Drag racing BS thread
 

The official 1/4 mile time threads were being overrun by BS posts, so I created this thread as a place to discuss anything drag racing.

Since this is the BS section, @Tenchix; and I got a ticket last night going "80" on a highway. No radar used. He tried to say we were racing, even though Nick was just following me... in the same lane... Bullshit end of the month ticket. I don't even think we were going 80, just cruising.
/End Rant

Im pretty fucking pissed about it.

how do either of those posts have to do with drag racing? ^^ lol

We are talking drag strip, legal 1/4 mile racing.

On a side note someone buy me some Belak Industry wheels please.

Chasing 12s on 15.5K Factory tire Full Weight 2013 MS3
 

'Sup guys... saturday 1/25 I was able to cut a 1.958 and that's my best. Know its not 'the best' but on a factory 2050 with 15,600mi, 40lbs of N2 (approx 3-4/32 left) felt pretty good. Went back to full weight from 12/21/13 when the car went 12.988 @ -178lbs. Stock it went 13.715@100.49 -178lbs @ 1600 + DA with a ford oem rmm and some plug tuning. My last stock full weight time was a 13.85@99.1 @ 2200 + DA with said ford oem rmm and plug tuning. Feeling good about the direction so far with a month off, glad to see 13.085 wanting 12.80s. The track was a bit wet out of the 60' and got out of shape a bit, on me... prob wasn't in the right groove. With more time in the car, hopefully we will see better 12s with the weight in than out. Last time when the car went 12.988 it did it at 1107 DA and @ 1/25 it was 145 DA at the time of the run + 200lbs roughly. I simply wanted to 'shake down' the car. My oil change was at 4100+ miles. Next time out I will make more preparation and see if I can bring back some good news having driven better. The car is sporting a new 93 tune/mid pipe I made and had tig welded together for my 3" eco. These are the only changes since 12.988 @ 12/21/13 :reporter:

that's a better 60' than I ever got on DR's
I think I need to pull more power out of 1st and 2nd

hey man, thank you very much. maybe this visual might help from my logs. I learned in reverse by feel to do this:

'boost with mph' look at green over blue. this is the 12.988 second pass @ 1.983. my RMM is an adjustable CFM uniit and I had 6 holes filled around back and 3 open. I did see a 1.96 on that setting on 12/21 but on 1/25 I was at 8/9 filled at 1.958. I can post the 1.958 once I figure out which log is which. for reference this car was making about 300whp @ sea level air at this time VD CF 1.09.

I'm going to have to start logging my runs and compairing what I think is going on with what the computer is telling me is going on and see if I can figure it all out.

yes. its a huge benefit

for those of you who use Drag Radials/slicks what kind of wheels do you have them mounted on, and what kind of tire did you use?

so far ive only used a nitto 555 dr 245/45/17 on an aluminum rim.

have 15x8.5 rims waiting on 8.5x26 slicks for this summer

Subscribed! I need all the tips and tricks I can get to help get my car to move faster down the track. I'm also looking to buy some drag radials and wheels.

Has anyone compared running bias-ply tires to drag radials? I'm going with Hoosier QTPs next, and on my platform the bias-ply tires are more forgiving on the drivetrain and they are easier to hook up of the line with manual cars.

I'm going to be the goat of this thread because I am going to be trying a set of 255/40/18 Lexus IS250 rear 2050 Sp Sports on stock rims haha. They are about as wide as a 245/40 Direzza Z2... if they fit might be a nice cheap option. $55 per tire shaved down to 5/32 even wear :O overall diameter will be about 25.5 shaved halfway and I'm at about 24.8 now with my shaved Factory 225mm 2050s. NTM... another 13LBS per tire might help with the launch... I might bomb. Looking to get into the 1.8's in my 60' ;D

If you want a low 60' in FWD, you need to get away from street tires.

Slicks or bust.

Everything else is just a waste of time and money.

16x7s and QTP 26 x 9.5 x 16 Slicks'..

doubleflusher: I know its slow and I am on factory tires @ 1.958 right now @ 3570lbs race weight. I want 1.8s on factory tire and once I have gained full goat-status maybe consistent 1.8s with this crazy wide 2050 tire unless I bomb. and yes you are right, I'm just a nut that thinks I can do it another way haha I just know nothing of these things you call 'slicks' before I played with drag racing I was turning laps at sebring with my stock 2009 MS3 I'm the idiot that took $40 shaved er33 bridgestones from the used tire guy and took em 41 laps deep. yup I'm that guy... but def. wanna learn. the car has so much more in it its silly I'm just not picking it up properly. I am confident that with a better setup with the same whp I can get to 12.50s with time. when the time comes, maybe something more rediculous... needing race gas and slicks to do it.

anyone car to share what rpm they have their launch control set at and why? I'm BT MS6 and have mine set at 4200 rpm but I was curious what other people were running.

I'm launching between 4000-4500 rpm, depending on conditions. 302 N/A on MT ET street DR's at 20 psi. No launch control, good old fashion clutch/gas pedal swap. Any lower and I bog, and higher and I spin. Not sure how this is going to help you though :wink1:

This was from the 26th at Test & Tune, was also my first time ever drag racing my car. Reactions times blow but the ET's are not so bad. Only mod is a JBR 88a RMM, still on stock dunflops

7200

5000 for me.

gotta ease into it. anything under that for me kind of just bogs.

w/ sprung 6-puck

Honestly, don't worry about reation times until you get better at launching your car. Trying to improve two things at once generally leads you to doing them both badly. When you do work on the RT you should be comming off the clutch when the third light comes on.

8% TP @ 3000-3200 and about .88-1.05 on the hit pull the clutch out and work in the gas, I get the foot to the floor around 5100 on a good run (stays there) and boost psi tuned to 1:1 with MPH till about 18.5, FFS at about 1.85-1.90 load. FFS limit @ 4777rpm. factory tire launch on n2@37.50psi. I pulled back my closed loop gate to .85 so I am in partial throttle fuel tuning for the hit. 1.958-1.999 currently. I think I'm trying a larger 2050 tire on saturday.

Curious what the minimum oil temperature guys wait for before a run down the strip.

I have to drive almost an hour to the track, wait about a half hour to hour before I get to run.
if my car was trailered i'd probably let it idle 5-10 mins.

Hitting up the drag strip for the first time and was looking for any recommendations you might have - coilover stiffness front and rear, tire pressure etc. I'm picking up some nt05s today currently on v12s, hoping to run mid 13s:tongue:

Just depends on how serious you wanna take it, if you wanna try and get the most out of the car, remove as much weight as possible, seats, spare/tools/sub, try to have about 1/4 tank of gas. My Nitto DR's seem to like around 15-16 psi, rear tires you wanna air up to 60psi.

With your mods, even at full weight, mid 13's should be easy as long as you're not blowing the tires off in 1st and 2nd.

Good luck

I run 255/40/17 NT05s. They're not gonna help off the line. They are for the road track and twisty roads.

Before you were on slicks would you feather the clutch off the line or just dump it at a lower rpm. With my current tire setup (v12s) and launching on the street I feather the hell out of the clutch so I don't spin. In your experience how much more grip will I see with a better street tires and launching at the track.

This is also coming from a bt speed!:deal:

Drag racing BS thread
 

I would launch at 4500, get a slight chirp if the tires sticking, and go wot. Track prep is going to dictate a lot in your launch. You could dial the power back in 1st and some in second to help. Tbh, if you want to get the most out of the car at the track, at the least get some Hoosier QTP's and let that shit rip!

*edit- if you're BT, I would think slicks should be the only option if you're wanting any kind of consistent short time.


Sent from my iPhone using Tapatalk

Yeah but I still spun easily with the torque spike of the k04. preload the drivetrain a little (as opposed to just dumping the clutch) and short shift 1st and 2nd are my recommendations.

I'll see if I can do some practice runs tonight after I get the tires mounted, if I'm launching at 3k short shift at 5k first and second?

yes. I only say that because 1st and 2nd rip by so quickly, and sitting and bouncing off the limiter does nothing to help your time. Also because it will be mostly wheel spin anyway. Everyone is different though, takes a ton of practice. My only other suggestion would be to make sure you flat-foot shift into 3rd and 4th. If youre worried about the 2nd-3rd shift, just don't think about it too much. An open-palm shove up and to the right slightly will knock it right into 3rd gear. Shifting 4th-5th is sometimes not necessary, because you will be right at the line. Its a judgement call. I suggest trying both. The shift 4th-5th takes a chunk of time though.

If track prep is shit and youre on street tires, you'll be lucky to get under 14s. Hope that there are a lot of people there using slicks that night, it will help a lot.

Also might be worth asking Mike or Lex to make sure your 1st and 2nd gears are detuned heavily. Running 20psi in 1st and 2nd will hurt more than it will help.

I will give this a go tonight, not to worried about FFS. Lex did detune the car, I'm only seeing 14-15psi in 1st snd 15-16psi in 2nd and full boost in third. Thanks for the help.:You_Rock_Emoticon:

I wish I could afford some radials or slicks for eecnm. It will be nt05's for me again. Hopefully I can cut down to a 2.1 with a little moderation on the right foot. I just want to get into the 12's on street tire and not fail so bad at tracshun. Last track day a year ago I was doing 2.3-2.4 60ft's which is worse when I was stock and all seasons.

About to purchase some wheels for slicks.

Found some 16x8 with a 4.5backspacing which is a 0 offset. Is that too much? I'm still on stock suspension. It'll be a huge poke I know.

Where are you guys finding slicks that are around 26-28x8-9x16. Only thing I can find is 28x10x16, which I'm assuming would work with the 4.5" backspacing.

You'll want a Hoosier qtp in a 26x9.5 16

Hahahahahahaha

I'm here again today

tapafuck

@lilred; Hahaha, good shit! Some fast cars there today?
@MZRSPEED; Do you think those wheels would be ok? Thank you for the link for the tires, I will get those ordered :)

They should be fine, it's really the only option you have if you're going with a 16" wheel. Good luck, looking forward to your track times.

Looking for some quick advise from a few drag masters. I am starting to read up more and more after getting addicted this weekend (my first time ever at the drag strip). I was only at an 1/8 mile track but I was mostly concerned about practicing my launch and getting a feel for the car at the track. My quickest 60' was a 2.03 and my quickest 1/8 was only a 9.2 with a 2.1 60'.

I was launching around 4k and let the clutch slip a little. I currently have the full face ACT clutch with a streetlite flywheel. After a few runs I really felt like the clutch wasn't grabbing as hard as it could. Maybe I was feathering the clutch too much? Is that the correct way to do it? I was spinning all four out of the gate until I was at about 25 mph. I could tell because of the logs I took during the run. The vehicle speed was bouncing everywhere. I am currently on all seasons and stock wheels. Is this affecting my time much??

Other than weight reduction and a custom tune, is there anything else that should be improved before I head back out and try again? I did make 10 passes without breaking anything, and that includes a rear end that isn't mounted yet. I feel my luck running out though lol

I know that I need to work on upgrading my cooling if I want to make solid passes back to back so that is also in the future.

Fully mounted and still wheel hopping. Should I give it more power coming off the line? I usually take off at around 3kand feather the clutch slightly before letting off. I was going to try Friday but, someone hit the wall at 120 and I was at the end of the line.

Yo guys, made goal today. Went faster this time so I was able to post: Full weight 12 second pass sub 12.988 on 93 driver tuned on the factory tire. Only had 1/32 left and it was nearly the same DA I had 1107 on 12/21 and today 1071. Only changes: Modded stock airbox and revised midpipe to remove a restriction wtih a re-tune. Thanks guys! SDG, Michael tire_1294_slip | Flickr - Photo Sharing!

dang good job.
how the heck you get under 2 sec 60 fts
so you gutted second cat?

thanks brother, I have a vid in my sig that shows how I did it. this latest pass was full weight, the pipe is revised to remove a restriction and I added a short cai stack to my stock intake box. 78 degrees and seeing about 265g/s I trapped with about 17.99 psi which really helped on the top end. car is making about 285-290 in the daytime now, it actually runs hotter in the 1000-1500 density altitude range now. https://vimeo.com/82587394 there's more in the car, I didn't quite drive its wheels off on saturday but I did on 12/21/13 I could not have gone any faster and it was enough... really pleased to have seen 4 passes 1.96-1.953 down to the wire on the factory tire. the last day it ran it was during the day with more track temp and that really helped... as soon as it got cooler for first elimination round... hop/spin. time for something new! haha I got to get back at that Mustang! DANG IT

I've seen clearer video's watching porn through static channels.

yup. my go pro had seen finer days. it eventually took a dive off of a 572 chevelle.

So close... wanted to say I was really happy I got to run with MZRSPEED tonight, he did awesome. Trifecta 12.1s on my home track in the 1.85 60' range, then belted out a 1.70 at the end of the night which was an incomplete run. I'll let him say more about it if he likes but from my end was awesome to have him back. Last time he was here and we met we were both running 14s haha. He was a full second faster than my car tonight. Much respect.

Who cuts a 1.70 sixty on the last pass and then misses 3rd like a rookie...me, that's who. Ran three 12.1@114 with 1.8xx sixties, adjusted air pressure, lowered LC and ripped a 1.70 sixty to only miss FUCKING 3rd gear, still managed a 12.2...fuck me 11's are soooo close.

Really great times! Goes to show, practice pays off. Can't imagine what you would do with a bigger turbo :o

P.S. Update your sig ;)

Subing.

Shoot. I went first time couple weeks ago. I hit 13.6 @ 111mph. My 60 was awful at 2.6. Get my 60 down to 2 or less I should be twelves easily.

Not bad for my first time. It was a fudging adrenaline rush. I'm hooked:)

I've been practicing my Launching and it's useless, I just sit there and spin! I'm hitting the track tomorrow and the only thing that's keeping my hopes alive is that I'll be able to lower my tire pressure.

Those are great runs, and I have sooo done that. Get a great launch and it throws me off and I miss a shift, or hit the rev limiter :)

Again, that is some great driving!

À prepped track must make a nice difference compared to back road launching

It's at the auto club speed way in fontana. I don't think they've ever heard of track prep!

Drag racing BS thread
 

First pass, Grand Sport Vette, stock I think, he ran a 12.281@115.96 with a 1.96 sixty. I went 12.118@114.57 on a 1.86 sixty. Second pass against the vw, lost the slip. Third pass, LS3 maro, cam'd I believe, street tires. He went 13.108@119.37 with a 2.19 sixty. I went 12.158@114.31 on a 1.82 sixty. Last pass, cut a 1.70 sixty, then missed 3rd. Still managed a 12.246@113.65

Was good fun watching your runs @MZRSPEED;

I need more practice to lower my 14.9 @95 lol

Yeah man, I launched in reverse my first time at the track in a ms3, so you're not doing THAT bad, lol.

Heres a crappy video of me running down a cummins

And no reason to get an upgraded tmic either if you can trap those speeds on a stock one. Good job as always.

Wish you were around when i started modifying.

First time at the strip, on street tires.

Solid work. 12s are close.

wkd of 3/1 I entered a NHRA bracket race because I got so close the night before to see 12s again in my factory tire car with all the furniture in place @ 3450lbs on 93. I had made some changes to the setup (minor, my new V2 SDG Racing eco midpipe and modified stock airbox, retune) and wanted to see a deeper time than my weight reduced time of 12.988. wasnt able to back it up that session, just not enough runs but I was able to see 1.954/12.943@108.94 which is my personal best at 1071 DA, my 12.988 run was at 1107 DA ;D tire_1294_slip | Flickr - Photo Sharing!

So first time at the strip was a blast, hoping to dip into the 12's with slicks. I've noticed a lot of people running Hoosiers, I'm looking to pick up some DR soon. What do you guys recommend as far as - brand, size, rim, etc?

My budget is about $600.

Drag racing BS thread
 

$600 could get you damn close to a 15" wheel/slick setup man, do it right te first time if you're gonna be serious about it.

Two 15" wheels will run about $260
Two slicks will be roughly $400
Spacers about $100.

And that's close to full price on everything, shop around for some used wheels, and I went with eibach spacers, so I'm sure a no name brand set would be much cheaper.

Thanks man, what were you running up front?

VW521- 5865P0 is the part #

McCormack Racing : Vision Wheels-Sports Star

8.5/24.5-15

As far as the spacers, you can find them on amazon, just look for an off brand.

One more thing, DONATE BROWNIE :wink1:

m & h have a new 26/8.5/17

8.5/26.0-17 New Tire!

makes me want to sell the 15"rims and spacers to try the 17s out

The 17's are tempting, but not enough sidewall.

Ohhhhh I ran a superslow.superslow at superslow mph. My 60' was forever and a half. Wassup?





























Seriously though best pass to date was 12.7@119. Wherever the hell the time slip is. Time to run real times with real tires this year :)

anybody actually make less power going from a stock TMIC to a FMIC? I had no idea that my old bag'O ice trick would be more efficient at the dragstrip than my new FMIC setup. now on the street fooling around its MUCH BETTER but at the track I cant seem to get the bats down to where they used to be without being a moron and boosting around the return road then hauling ass to the staging lanes and hoping the cool air stays in the car.

btw, this is in a ms6 at the 1/8th mile instead of the QTR mile so I don't have as much time to suck up cool air while going down the track. its all about the launch at the 1.8th mile and im going slower now that ive gone FMIC and its killing me..... ugh!

Get jbr thermal insulating gaskets.
Maybe spray some methanol.
Post a slip.

I just saw the throttle body gasket jbr spacer thingie that jbr sells last night and I think for $30 bux I can handle that.

I have absolutely no experience with meth on disi cars, what are some good kits?

lemme see if I can find a slip that doesn't suck.

last Thursday I ran a 8.7sumthing with a 1.85 60ft at 81mph but I cant find the slip anywhere. my goal is to eventually run a 12.99 at the 1/4mile or a time equivalent to it at the 1/8th mile.

Get the coolant bypass and manifold ones too.
Big difference.

thanks, I REALLY hope you aren't screwing with me, ive seen these kind of "gizmo's" on mustangs and other cars and they never seem to work. but I will trust you and order em next time I get some cash. I think I will do at least 2 of both to make them as thick as possible. has anyone done that? or has every one just done 1 of each? jbr says you can do up to 4...

I have them on my car, yesterday my intake air temp was 9 deg higher then ambent temp after city driving for half hour.

thanks man. if I cant get this under control I don't know how I will continue to drag race with a FMIC setup at a shorter track like the 1/8th mile

So why did you decide to go with such a short tire? Wouldn't the 26" help keep you in the k04 power band even more?

I was just wanting to try a different setup. I haven't had a chance to try the 26" tires since I've had the spring bags installed, prob try that next.


Sent from my iPhone using Tapatalk

I mean this setup is obviously working for you! I was just curious. I still haven't had a chance to try out my slicks yet, but I need every bit of height I can possibly get with this setup, so I can ride out 4th.

Those look like a decent option for pretty much bolt up slick setup. May not be a whole lot of sidewall but I'm sure will do the trick.

With an MS6 - stock clutch, Has anyone used the handbrake to pre-load the drivetrain before launching?

What are you guys doing about springrates for the rear?

p.s. who's launching in 2nd?

Footballs.

Diddo, i think i might try a 27" tire.

A 27" definitely will not fit on a Gen1. Found out the hard way that my 26's wouldn't even fit without rubbing the bumper if I turned the wheel even a little bit. Hence me running at ENM with no front bumper.

What were you running?

26x8.5x15 M&H Racemasters with the vision wheels on 25mm spacers.

I adjusted the front height all over the place and that didn't matter at all. As so as I would turn in some, hit the font bumper. Gotta modify it somehow so I can start running with my bumper on.

Are you lower then stock?

Nope, and I even went up quite a bit higher than stock to test, but it really wasn't the height that was the problem.

Rain on my parade...

I know the M&H RM have a:

8.3" Tread W
10.5" Section W
26" diameter

Where the hoosier's I was looking at 27/10.5 - 15

9" Tread W
10.1" SW
27" diameter.

Current 245/40/18

9.1" TW
9.8" SW
25.8" diameter

I figured there may be a chance. Guess I'll just do regular qtp and 16" rim. Sigh.

I'll be trying to set them on a smaller spacer first to see if that clears it up. I'll let you know once I try it.

Yeah biggest thing is not to get a wheel that pokes so much...but hard to fit a 15" wheel on the front.

for the guys running slicks... what are you guys setting LC at if at all? i have a set of 26x10.50x15 MT streets ready to go. previous owner (only made 2 passes on them) was dumping the clutch in the 5-6k range to keep from bogging down. suggestions on where to start?


Al

5250 and go up/down by 100 rpm depending on track conditions, until you find the sweet spot.

Have you test fit them yet? Could you post pix of them on the car when you get a chance please, that's some serious tire.

here is a test fit with h&r springs. i'm switching back to stock springs next week so i have more room.

@LumberJack;

The reason those ET Streets fit so well is because actual tread width is only 8.3" measuring according to the MT site, section width is 10.5" huge difference. They're fitting very similar to the MT ET Drag of 26x8.5x15 because the actual tread width is only 0.2" different at 8.3" tread width.

interesting. i just put a tape across the tread and came up with ~8.5". gotta love inconsistency of tire measurements, even within the same manufacturer.
