looking back at it, it's really not that funny

I don't get why you think the gt30 is laggy. I don't really consider my 35r that laggy and im at 8.1:1 compression.

J, whats your powerband like?

the gt30 is NOT laggy. I start feeling some hard pull in the low 3000's and by 3800-4000.... you forget there ever was any. The only time it feels bad is if you bog.... and then it just means you forgot to shift.

I have 10-12psi by 4000 and by 4400-4600 i usually have full boost...i havent datalog'd in a while and my rpms just sky rocket once you hit 8psi. by 3800 rpms ur already pinned in your seat. when my second head gets back from dee at reactive racing I will be able to rev to 8500rpms so i'll have full boost from 4500-8500 rpms. should make for a fun day at moroso the first time i go back :)

I would love to be rev my car up to 8k......now how do i do that?

Well its easier for me. I just have to build my head and have springs retainers and valves that can flow enough to tolerate it. That and a turbo that is efficient in those ranges. You guys have to many issues since you have fuel problems as it is and the throttle plate issue. on pump gas i make 404whp just under 5000 rpms so i'll realistically have a 3600rpm span of 404whp. i make 310whp by 3800rpms and 250 by 3000 rpms so i should have a solid FAST 5000rpms in each gear. i am hoping to be able to do 12.2 or 12.3 with this setup on pump gas and steet tires. and then im gonna add water meth at the end of the year to try for 10s on slicks

the next question im gonna ask is COMPLETELY just out of curiousity...im not trying to start anything. is the majority of this site all protege garage fan boys?

This site has fanbois from all the companies. Cpe has their cheerleaders here, pg has theirs, streetunit has theirs ect ect

whats bugging me here is that you go read what the ms6 guys are doing and the come read what the ms3 guys are doing and you see the same mods but less power on the ms6 guys. i honestly think that the three guys are apples and the six guys are oranges. i don't think we can really look at what they are doing and expect the same on our cars for whatever reason. the three guys are making 30 or so more horse with less mods than the six guys in some cases. case in point Laloosh and Driver.

day of release we can get custom tunes made for the Accessport thanks to our friends here in Chicago named P&L.

say what? Dont drop that little tidbit and then runaway zach. how the hell will this be done?

red:i thought they weren't going to release tuning software till the AP sold enough units.

and J at this point I'm a fan of whoever can get the parts at the lowest rate. Shit I ran onlyTXS for almost a year........... fmic, tbe, sri.
Than i started ordering things from PG..Ken just has the things i'm loking for at the prices at I could afford. I think at this point i've bought things from every major vendor. I've had 2xfmic 3xsri 2xdp 1xmid pipe 3xbov/pbv 2xcbe 2x rear engine mount ..... i'm pretty much a parts whore.
p.s. nice street unit sticker j/k

I'm saving up for fuel pump upgrade right now. I also prefer the responsiveness of a smaller turbo for daily driving. If I eventually am able to afford another daily driver, I will probably go with a larger turbo.

I dont think P&L is going to be able to do that since ive now confirmed with 2 Cobb tuners in Ca that tuning software will not be ready for the MS3 for a few months. If they are going to be able to do that for you guys, im sure a lot of Cobb tuners will be raising their eyebrows...

oh i wont deny im an SU fanboy. cullen is probably one of my closest friends so of course im going to support him. the only reason i dont support ken is because he confused me with someone else and then bashed on me for asking for free parts when i already was fully built under sponsorship from hiboost turbos...he claimed i wanted him to GIVE me everything...i dont think i've ever asked any company to give me anything...anyways but ya i was just curious...i actually really enjoy these forums. theres no bickering like the m3f board. if you look at my posts over there im always a dick cuz im so tired of the same shit over and over but here its so much better and so much calmer and just friendly people with friendly attitudes. i sometimes feel like i shouldnt post because i have different components but w/e heh...i just wish some guys were closer. id love to film me running some of the faster speed3's

Ive been sponsored on several vehicles and never paid a dime afterwards for parts/tuning. You have to get to a certain point and prove you are worthy to get kickdown's.

Oh believe me i know. I've saved 12 grand now as a result of sponsorships...it took me being boosted and fully built to start getting attention. At that point I got things under cost, labor free, some parts, free (only from 2 of my sponsors) but I more than make up for it for them. For example, tbk performance (brother of juan from hiboost) has had to 11k builds, sold about 9 kits, and 3 gears as a result of sponsoring me.

They are beta testing the software for COBB. It helps to have friends with connections.

Ahh, well there it is. Are they going to hook you guys up than?

So what is the final diagnosis on your engine? I last saw that you had a very wicked metallic sound that ramped with RPM. Did you find you actually toasted your engine? If so what failed?

Tks,

yeah these forums are much better, i was getting tired of people asking stupid questions on other forums like if they need to use premium gas....DUH. Well your car is a beast man I am sure it would give the faster speed's more than a run for their money.:love:

PG fanboi here, but that has nothing to do with my turbo choice. i could have gotten a gt 30 from them for a steal too, but that isnt what i wanted. now that i hear people saying "its not bad i have full boost by 4k!) i say HOLY SHIT THAT IS LAGGY !! with my set up, which keep in mind still has a stock intercooler and downpipe i can have a full 20PSI by 3k. now with the new forge WGA and turbo, DP, and IC on its way i only expect it to get better !

I definately would not want full boost by 3000rpm. I would never stop spinning. I have a quaife lsd which FAR out performs the speed3's oem lsd and I still have trouble keeping traction in certain conditions. I have a 35r and spool from about 2800rpms on. I make wastegate (6psi) by 3600 I would guess and my full 16psi on pump gas by 4400. On days where there is little humidity (i live in miami so its almost always 100%) i spin my tires STARTiNG at 5000rpms because it gets so torquey up top for me. If i were to have full boost at 3000rpms I would have a useless daily driver. To say that you are happy spooling at 3k its like saying your happy not making big power. Your turbo (I am guessing still the stock k04) is completely innefficient at 20psi. Not only will it be flowing excessively hot air but it doesnt flow that much air to make good power at that boost pressure. I don't know why people think 4000 and 4400 rpms to hit full boost is laggy. If i punch it in second gear at 30 or 3rd gear at 45 you may get a car jump on me but within 1 second i will be next to you and the next second 2 cars in front of you. Lag is bad - I do agree. But a properly sized turbo and a good tune allowing for a decent spool up (and yes full boost by 4400 on a car that revs to 7k and now revs to 8500 since i built the head) is a GREAT spool. I would MUCH prefer 1000rpm later spool for a much more efficient and powerful turbo. While you spin I'll maintain traction. Once you stop spinning I'll be in full boost. Now don't get me wrong. I LOVE the speed3. If it had been out when i started building my car I would have gotten it. I am glad i didn't because of how tricky it is to mod it and go big b/c of fuel issues but its a great car. I just love the platform I started on. I had to build my motor and tranny but to go big on the speed3 you have to as well. I make 400+whp daily and it will be more once the new head is on. To have that you will have to build your block as well. I would say the tranny might not hold up as well but thats up in the air because your gears are stronger than mine were stock so I had to get billet 3rds and 4ths since i snapped so many stock ones. Anyways....this is why i like this forum...much more intelligent bickering as opposed to m3f where its people with no knowledge making statements :)

the last thing i want on this car is faster spool downlow.... I want that lag till high 3s low 4s. This motor doesnt like to be loaded up downlow.

I agree!!!! This is the same reason I argued the gt30 or even the gt35 may be safer than the 2871 in previous discussion. Of course not at full bosst, but like Whoosh and I are doing it.

I still dont have that lean spot that was so noticeable with my old turbo and these mods.... even tuned. The fuel we dump goes in and stays in...whether its the standback doing it or the later spool... who cares.

Id bet that lean spot is the motor killer in all of this if I had to bet.

^the best i could do, to fix the lean spot was 12.6 before 4k...guess that doesn't help the motor blowing up.

In what way does the quaife lsd "far outperform" the ms3 lsd? Just curious.

oh, and with huge power, you still arent going to have traction at 4000rpm in a fwd car, as srt dudes, they spin through third with bigger, laggier turbos. wheels spin is an inevitability no matter how your car is tuned when you are fwd, the real answer is stickier tires, not laggy turbos. Run 245 dr's in front and enjoy the boost more. I do agree with loosh though about the low rpm load, this car hates it, anyone who has got on the gas when in fifth at 50 or so or in sixth at 60 or so knows this. Car feels like it's going to shit it's guts all over the place, this car just isn't a huge fan of boost, like I have always said. I can't comment on guys with upgraded cdfp's, but stock, this car seems like it pissed off about being boosted.

the quaife lsd in my tranny is aftermarket and is a true mechanical / gear'd lsd...the one in the speed if im not mistaken is electronically controlled...

nope it's not electronically controlled

what kind of LSD is it?

cone-type Super LSD limited slip differential.

yeah... but the issue isnt at 4000 its more like 3000-3500. I'll go look at my old dynos, but if full boost is on in that range, I just dont think we have enough fuel there to support a turbo fully spooled in that range.

Yes, cone clutch, like an Auburn, except without much preload....

According to cobb there is no throttle plate closing problem and the dropoff of power is due to the turbo running out of air. So I will ask in this thread are you guys with big turbos making power till redline?

I have driven Paleriders beast. It was pulling like a scalded ape at 6600 rpm in 4th with no signs of dropping off, in fact it seemed to be pulling harder as the tach climbed (or maybe I was running out of 2-lane road, its all a blur....).
-enganear

It does in fact fall off after 6400 rpms... but only down to about 300whp.... then the real drop off is after about 6600.

http://i253.photobucket.com/albums/h.../346whprpm.jpg

on this particular subject i.e. the throttle plate
I'm going to have to say that Cobb doesn't know what they are talking about

at 5000 RPM my plate is open over 80%
at 6000 RPM mid 60% open
anything past 6200 it drops like a sack of potatoes
that's at 20PSI on my GT turbo

although the car is seemingly still pulling hard and it is in comparo to the stock turbo...you are actually losing power>big time

I think its a combo issue. The TP is closing, and the stock turbo is leaving its compressor map, and blowing hot air.

http://i165.photobucket.com/albums/u...pressormap.jpg

Whoosh,
Do you know if anyone actually watched the TP on the speed6's to see if it had the 110-115% issue that the standard 6s's had? I remember that twowheeling did some experiments with the 6s Throttlebody, and found the plate actually went past the 0 mark (with 0 being 100% open and completely flat -- ) and actually started to close again. ie, at max throttle input, the car would be at 115%, which was actually 85% (because it started closing again as it went past the 0 mark)

Below is an exaggeration, due to lack of degree options with text. :)

Closed [ \ ]
Open [ / ]

This was one of the reasons a large # of owners felt the car was faster with less then max throttle input. (ie accelerated faster with partial input over full input).
