Lol good one. I would rather a ms3 make it to the 11 in the states since no ms6 in the states has done it. Congratulations a ms6 did it first though....more commitment from overseas I guess.

And again. Awesome run pat. Would have loved to see that 11.39, hope you break 10's dude.

It had been the greatest drag event of the year in Ukraine on saturday 150 miles away of my home. It was way better traction there - aviation concrete versus slippery asphalt I've used to. So I had to raise LC revs from my usual 5,800 to 6,600 to wheelspin. Though I still had wheelspin to the end of 1st gear and missed 2nd gear several times. It's becoming my headache - I miss 2nd gear every time it wheelspins at 7,000+ rpm :worried:

So I've managed to drive the whole distance only three times and each time I had random problems like fuel cuts and limiters. And there still were rich AFR and relatively low boost.
The best run was 11.4.
Now I have several ideas of further time improvement but they all need some time to be embodied so I'll let myself take a lil break.

Though that track has both speed trap and 60ft sensors, they neither showed them to people nor even installed the clock they have :worried: They told only ETs.

Fuck that looks fun.



Pat, i'm glad your proofing out the transmission, PTO and rear differential. Giant thanks man!

Man i have to get back into my car!!!! good job got me by a 1sec..

lol i can't believe i just watched a video of a ms6 hanging with a gtr.:notworthy:

are you flat foot shifting?

Are they making you start after the gtr? Looks like he gets a split-second jump on you both runs

Damn man, very impressive keeping up with a GT-R. Both runs it seems the GT-R is jumping first, otherwise I think you would have had him. Either way good job man.

Shit like this is why i am trying to slow down getting on the forums!!!! here i am trying to focus on other things and now my friends are all over me about going back to get in the 11's FULL TILT.....

So its back on i will be back SOON!!!!!!!!!!!!!!!! sorry for the thread jack.... credit cards are going to start going :aargh4: again

Meh forget it.....

three things:

1) nice run
2) was the techno viking there? that was the first thing i thought of when i heard the music
3) everything is in a foreign language except at 0:53 when the guy says, "ferocious start"

Nice runs man! Keep up the good work!

The time starts when you cross the light path, not when the light goes green, so he was probably just getting settled. Note in OP he sits there for several seconds after the light turns green.... this is the way to do it. F the person next to you, and concentrate on your launch.

7900 RPM is the thing I'm most impressed at. I saw that hertz pic and I was like WTF! I guess I missed that on the last thread. Congrats on such an amazingly successful and consistent setup. You probably build engines better than I build sammiches.

10's are in your near future...I have no doubt. Even if your track IS off, you are still the fastest guy on here by FAR. :147:

Eibach Pro-Kit & Bilstein HD remained as they were.
Cuz Eibach Sportline kit isn't being produced anymore, I need to choose other tough springs or maybe some coil-over kit.

But I've installed HardRace trailing arm bushings and adj camber arms and set 0 degree camber at the rear instead of -2.5 degree I was running for last year.


Sure, unless you know some aftermarket ones for MZR-DISI ;)


Thanks, I hope too :)
10s trip def wouldn't be as easy as 11s one. Since I've made first 11s run I had no 12s runs, but some ten 11s ones. Now I can actually claim that the recipe is simple (at least for MS6): 400 awhp to the redline, car strip and have nothing break - and you are in mid 11s already. Even with soft suspension, dirty asphalt and some 1.8 sec 60 ft time.


first I release the throttle and push the clutch pedal, turn off gear, then release the clutch pedal, push it again, switch to next gear, release clutch pedal and push the throttle lol
of course FFS ! no FFS = no good ET


Thanks.
It was only one run with GT-R, but two different cameras lol
But no way I could have had him. With catless exhaust and AMS reflash it showed 480 awhp at local Mustang dyno where my MS6 showed 394 awhp last time when I ran 12.01.
This GT-R's best time is 10.9 or 11.0.


And thanks again.
I wish to rev 8,500 at 1st gear but I'm afraid of breaking something down. Also I have some doubts about HPFP durability at those revs.
I've set 8,000 rpm limiter and each time I miss 2nd gear it hits 8,200 several times. Scary lol

so what you're saying is that you're granny shifting and not double clutching like you should?

I'll have to go back to your build thread and check... but what springs are you running in the valve train again?


I'm so lazy... had to ask instead of search lol.

stock valvetrain can take 8k all day, its the stroke length thats the biggest factor (at least on stock bottom end)

How do you know lol. Most i've rev'd anyone out to was 7200.


And Pat, your revving to 8000 AAANNNDDD maintaining 400whp? Plus running as rich as you are in those logs you posted? How in the hell are you getting so much fuel in the cylinders?

His car is a squirter...that's how.

At 0:53 the guy said "хороший старт" ("horoshiy start") that means "good start" in russian lol


stock springs.
do you know any aftermarket ones ?


I'd like to know maximum safe revs for my engine...
Could you suggest ? :)


It gets fuel to cylinders itself, I just push the pedal lol
Seriously, I didn't understand what do you mean.. CP-E HPFP still holds 1750 psi to my current rev limiter, injectors aren't maxed out and also 625 ml/min methanol nozzle helps with 75:25 mixture.

I don't know my actual power in 11 sec runs since last time I visited dyno before 12.01 sec run.
And I actually had rich AFR in 11 sec runs, especially in the last ones - you could notice contunious black smoke in my last video.

I'll visit dyno soon I hope, but I already calculated my power approx by acceleration/weight. I'll post some graphs later.

squirt squirt...

wish I could get my girl to squirt.

This Australian guy says he's running eibach springs:
http://www.mazdaspeedforums.org/foru...85/#post681984

I was just curious if you had upgraded the springs or retainers. Judging by how his threaded ended.... i kinda question the credibility of the valvetrain.

I don't have any advice on what the upper rpm limits of the stock valvetrain is. I've rev'd a few cars out to 7200, and i think some people have done 7500, but above that is unknown imo. If your revving to 8000, then that's amazing.


I'm not sure how your measuring dutycycle, but with direct injection, you only get half the normal window to inject fuel (even less when you take into consideration spark advance).

So perhaps your 45% IDC corresponds to 90%????


The AP reports duty cycle appropriately (at least as far as i know), and many people have kissed the 100% mark, and even gone above it a few times. They're probably spraying during combustion.

As RPMs increase, this problem is exaggerated. Increasing fuel pressure helps, but is limited to the relief valve crack pressure of 1885 psi. Bigger injectors aren't available yet. And 5th port injection, like your doing with the meth, is probably the simplest solution. Your 625 ml/min nozzle is probably very similar to what most of us are running (d07) with bigger turbos.


Here's a lil video showing the injector pulse width on a ~360awhp ms6. You can see first hand how the injection pulse width gets very close to the spark.

Here's a pic showing which trace is which:

Here's the video:

If your running stock injectors, and stock fuel pressure, your probably getting pretty close to the limits of the stock fuel system.

Do you have any issues with spark blow out?

Holy shit! That MS6 is crazy. The way it leaves the line.......

Great job!

Hot dang! :arms:

WOW! This is some impressive shit.

I still don't know what you mean about your shifting. Whatever it is its working for ya.

Glad to see 10s getting closer O_O.

Keep up the good work.

I gotta wonder:

A) What this car's 0-60 time is? Gotta be under 4 sec.
B) How much torque is this thing making?

He was being sarcastic. The technique he was referring to was double clutching. not something you do drag racing.

He said hes flatfoot shifting. slam gas, slam clutch, slam gear, pop clutch. wide open on the gas pedal the whole time.

He feel like our Ukrainain friend still has some secrets

Ya i was a little l8 picking up on the sarcasm.

Stock springs and retainers, but my valves lightening saves more weight than any titanium retainers could.

My device (MAF Emulator) simply reads absolute injector duty (% of injection time at 4 cycles (720 degrees) period).
From that you've written about AP logging and its ability to show 100%+ values I can make the conclusion that it utilizes the formula to show some 'useful' injector duty, like:
AP INJECTOR DUTY (%) = ABSOLUTE INJECTOR DUTY + (SPARK ADVANCE deg / 360 deg * 100%) + 50%.
In example, some engine sprays fuel strictly till the ignition and it has 18 degrees of spark advance. In this situation my log would show absolute injectior duty = 50% - (18/360 * 100%) = 50% - 5% = 45%. While AP log would show 45% + 5% + 50% = 100%.

Since I already saw 46% of duty in my logs several times with some 18 deg spark advance I believe I've already kissed 100% AP injector duty lol

This is bad news for me.
But good news are that I was running very rich AFR and middle size methanol nozzle. I can still try 12.0....12.5 AFR, some 1000 ml/min methanol nozzle and 100% methanol itself.
Or do you already know some safe way to rise the fuel pressure in the rail ?

I believe I had not, even with 31...32 psi of boost.


A) My best 0-60 was 3.1 sec by my logs
B) 434 awtq WCF in the last dyno run http://www.mazdaspeedforums.org/foru...433-wcf-90975/

any hard part updates pat?

PTP makes an upgraded relief valve that raises the possible rail pressure to like 2250 psi... and from what i've read they actually work. My guess is the fuel would become pretty hot at that pressure, but i'm sure you'd still see some improvement in fueling.

I think most people are simply supplementing with meth like you are.... more nozzles, bigger nozzles.... multi port meth injection....

It's not pretty hahaha.

While tuning the car at July 2011 I've made 'dyno run' with accelerometer Sprint SG-2 (like G-Tech) on public road. It calculates power by acceleration taking in consideration multiple parameters like weight, chassis rigidity, gear ratio, air resistance etc. But it knows nothing about the ambient air temperature and density, so such run should be considered as uncorrected.

http://mazdagarage.com.ua/pat/www/110713x800.jpg

Two days past I've ran 11.393 with the same setup and tune. I simultaneosly wrote the logs with MAF Emulator (it was posted earlier http://www.mazdaspeedforums.org/foru...49/) and the same accelerometer Sprint SG-2 in 1/4 mile mode (Sprint SG-2 - ..).

With roll-out 0" set it showed little worse time than Race America with its 12" roll-out.

http://mazdagarage.com.ua/pat/www/110715x800.jpg

I've dynoed 434 awhp corrected only at September (http://www.mazdaspeedforums.org/foru...433-wcf-90975/) and actually never tried that tune at quarter mile. 434 awhp were shown with higher boost, leaner mixture and more advanced ignition.

Nice. That's one quick ms6.

I feel like some suspension tuning would make a big difference? Coilovers mayhaps? Seems aweful squishy on your first shift or two...
