Since the DI turbo cobalts are your best comparison fastest sock turbo time for the cobalt guys is 11.952@117.62

Fastest built motor big turbo owned by a normal person is 10.9 @ 133 with a pte5857


There's your benchmark guys go get em.

I didn't think their interior plastics could handle those kind of times


Sent from my iSlo

im sure with the right BOV, the ms3 can do 11.6 or11.5

Kmac and I will remember your statement and hold it to you.

I'm sure 11s on stock turbo is possible. Next summer seems pretty soon though

im just waiting for phate's e85 tune to hit the track.

Fastest stock turbo times was 2.5 years ago before really any e85 options were avaliable for the cobalt. As of now the only hpfp upgrade available to us is through zzp and I believe you have to buy the cam upgrade to even get it. I do know that a fellow trifecta dealer in florida who has just intake, catless downpipe and tune went 12.5's on drag radials with a e85 tune. So as with the ms3's I believe you will see more Slobalts in the 11's with stock turbo soon.

I won't be stock turbo next year so I can't exactly do 11's on it. On a 24psi aggressive 93 pump gas tune I ran 12.6 @ 116 with CIA catted down pipe, K&N Sri , and the tune. This was on nitto nt-05 street tires shaved a little (they are my autox tires I run). It sucks there isn't a e85 station within 1 hour from my home town so I went back to pump gas. But I will tell you this on e85 my car moved son lol sigh the woes of living in redneckville Mississippi.

Also another reason you don't see many cobalts in the lower numbers is honestly tire selection. Because we have the factory brembos unless you switch them out with the older 05-07 LSJ Cobalt SS brake calipers you can't run anything smaller than a 17 and then your options are severely limited because of our 5x110 bolt pattern unless you do the 5x114 hub conversion. So unless more people want to give up there brembos I doubt you will see to many fast track times from cobalts over what I have talked about. I myself will probably keep my brembos because I autox my car a lot.

i wouldn't say this is a fast track like MIR for instance, but it is a sea level track. the car could have went 12.3 but we were getting some head wind and i was not trying to break my car being 350 miles away from home

I agree with ya. 1.65-1.75 60ft. With a nice bolt on setup, a kick ass e85 tune, the right set of slicks and a few lbs of weight takin out and itll happen there is NO doubt. It just math. I still dont think 11.6 is out of the question but 11.8-11.9 is probably where we will see the first one. I definately wouldnt mind being the one to pilot it. LOL You never know.

if anyone wants to set up my car I'll let you pilot it!....no?

turboxs rfl???

your wrong,

stock turbo record is 11.6

*you're

you are not a reputable source of information. Post links for reference.

i owned a cobalt tc before this and there easy for a good driver to get into mid 12's and a great driver like the one at zzp into mid 11's.

@Darksun280

ZZPerformance - Go Fast... Not Broke

Fastest stock turbo LNF - 11.62@119mph
Fastest LNF- 10.99@ 133.6mph(27psi), 612 whp sae (34psi)

and for shits and giggles look what the lsj did
2.0 liter LSJ accomplishments- 9.82@ 141.6mph (30psi), 898whp (54psi)

I believe Darkie was talking about fastest stock turbo not a shop car which was cmiller at the time he posted. Or that is what I thought he was getting at since he said as much in his big turbo comparison which is why I did not correct him.

the 11.6 was stock turbo tho. they ran 10.9 i believe upgraded turbo

I was just going by the fastest one I could find a pic of a slip or some proof. cobaltss.net had the fastest with a slip listed as the 11.9 stock turbo.

yea i think that was cmiller. the lnf motor is badass. but i had it and the interior is wack and cheap as fuck. but i can say my speed3 is getting close to my balt speed wise.

so what is the cobalts T/C doing for fueling? (the DI models) to run 800 horse.

Y on earth would i put a cobalt as a benchmark...

Sent from my left nut.

Because performance wise they shit on us.

Not true. ON a track the cars are very comparable and with both setup similar suspension wise they are gonna be very close. Ive driven both setup similar and they are close and the cobalt driver agreed. Bolt on for bolt on they are close and fully bolted with aggressive e85 tune they arent that far off either. And the cobalt has a bigger/better turbo. I mean 360-380whp is about average max setup on the cobalt. The ms3 has proven to do 350whp and I dont think its to far fetched to say 360-370whp is doable on a nice setup. I think we have several on this board over 350whp with big torque. Then you put a bnr stg1 on our car which is gonna be very similar to the cobalts turbo and 380whp isnt out of the question. So no they dont shit on us, we just dont have enough guys on this site that are doing cool shit on stock turbo. Its small I know and its just so much easier to put a bigger turbo on and get your power that way. But you take a 350-375whp k04 powered speed and put it up against a 375-400whp 3071/3076 speed and you get a major ass whoopin put on the big turbo one. Why you ask.... (BIG BAB BOY TORQUE). Dont sell the ms3 short. It can hang and I think 2012 is the year for a few fellow members to prove the point that the speed3 isnt living in the shadow of the cobalts and srts any more. Several including myself have already passed plateaus that we thought couldnt be achieved. Next year we will see even more cool shit, including stock turbos hitting low 12s high 11s, and possibly the first 10 second speed3 and maybe even on stock motor. Mark my words with a slew of guys like, me, Dustin, Phate, Anthony, Kmac, Erich and many others doing cool shit, its gonna happen I already have a stock turbo speed as a donor car to beat my stock turbo record, and hopefully beat Phate or that fast genpoo cat to 11s. LOL Thanks Zlatan.


Continue on

im not knockin the ms3 nor the cobalt, its just a fact that they make power easier then us, obviously because of the slightly bigger turbo and that they don't have the fueling problem we do.

would i own one? probably not because of the inconvenience of the coupe and horrid interior, but i do admire and respect them for what they are and what they are capable of, same thing with the ms3.

Plus id love to see all those people you mentioned do great things on this platform with our without stock turbos.

:bigok:

lol cobalt rant

I really dont think a high 11 is impossible with a good driver on a good track. 2012!!!

You did say that they shit on us performance wise, which stock for stock its drivers race. however they do seem to respond to bolt ons better. I think their main advantage besides the turbo is the gearing. But i do not agree with them "shitting" on us at all.

ok so what are the cobalts (DI) doing for fueling? they got bigger di injectors?

The 800+ hp cobalt is a lsj cobalt so it is not DI.

Matt's 600+ hp cobalt uses a better cam driven hpfp that zzp has developed to coinside with their cam upgrade.

The 500+ whp cobalts are like the ms3's and use the stock system tweaked in the ecu.

Hope that answers some of your questions.

i looked up the cobalts forum, and found that the LNF stock turbo cars are the DI cars and they hit 10.99 in the quarter. so to say they are still really rocking in the 11s is a good guess, same as us.

DI is still so new and aftermarket kinda stays away from. we just gotta change that.
i think thats the only thing really holding the platform back, but feel its going to change soon.

and has anyone looked into better cams for the MS3, i mean on the HPFP side?

is it possible with a different lobe at the pump we could gain from it??

Interested to see 11s from the ko4, sucks the speed6 has the drivetrain loss.

i wanna see how your pu looks with a single exit exhaust

@2011speed

you looking at doing a single exhaust or something.

I did 12.737@108.51mph with Hossier DR

Mod are: Cobb AP , Cobb sri and tune

Im just curious how it looks on the pusince it has the two bumper holes

I'll post a pic sometime after I get it redone. Shit is to loud I'm adding a resonator and maybe aero muffler

I don't think the tiny K04 can trap in the 117-118 mph range even on E85.

with NNNAAAAAAAAAAAWWWWWWWWWWWWZZZZZZZZZZ?????

I'm gonna hit 11's on the stock K04. I went 13.82 the first week I had my car bone stock with 200 miles on it. Right now I'm working toward a very aggressive tune with @rfinkle2 trying to see what we can do. I think the stock K04 can handle 24-25psi safely if done correctly tapering low to redline. I have the driver mod to do it. Just need to hit my setup right and get the tune going well.

The problem with the K04 is that it is comfortable running high boost too early in the rev band.

After a shift, you are hitting a point on the compressor map that is really only good for 20 psi (very optimistically).

I think it doesn't hurt to try (to hit 11's), but if you eventually want to run > 21-22 psi on the k04, we need to think about upgrading to a 3 bar map sensor and run heavy concentrations of meth or e85.

@ this time, I think it will be very hard to hit 11's on the k04 without a 100 shot.
