Term- he has a stock clutch. I honestly can't believe he doesn't fry it already. Some seem to be better than others, but we certainly can't be pushing more torque then he already does.

As far as my car goes, I have close to 500 dyno pulls on it now, to go along with hundreds of hours of experimentation and parts development. Obviously we wouldn't pour a 5 gallon can of E85 in someones car with half the mods, make 2 pulls and make the same power as my car.


Here's another example-
2003 Impala with stock bottom end was running our turbo kit. Lots of people have bought this kit. Many have run low 11s and trap in the high 120s. A couple have hit 130s, but with zzp attention, this Impala was running 10.0 and trapped close to 140. YouTube - Turbo Impala Runs 10.09 at 138

How about my Grand Prix drag car that ran 8.65 at 159?
Why did Zoom's Grand Prix run 10.8 on the stock gen 3 M90 blower?
Why did Tim's Grand prix run 10.9 with a 60-1 turbo on stock exhaust manifolds?
Why did Vanessa's GT run mid 12s at 107 on the motor when the next fastest on the motor was trapping less than 100?

It's because we are very good at what we do. It's just the way that it is.

I am glad you are good at what you do. But this is going way off topic. You ought to start another thread that explains all your shop projects and cars. Show pictures, dyno sheets, videos. I am sure you will get a following.

Matt M

I have plenty of other threads, but I don't see why that matters. This is the thread where people are trying to discredit what we do. Therefore, this is the thread where I am responding to these posts.

EXCESSboost

I don't see anyone descrediting what you do. The internet is full of people that just want to strike a nerve to get a reaction from you.

Matt M

Good point. I see what you are saying.

The 2011 turbo regals I see for sale only have 220 crank HP not 255 ?

Matt M

Yes, but they are designed for flex-fuel capability, so it's possible.

Yeah sorry. The 2012 is being advertised as having 255. The 2011 is 220.

BlackBeast!

I was thinking the same thing and the pump is rated to push more than ours, thats why i asked that question. If you guys get to try it out please let me know lol

Sorry, but this was funny. I just got done reading this thread. It took me two days.

91 octane 28 psi results coming soon on Drew's car. I am praying that the HPFP can pump enough gasoline to run at this power level. E-47 at this power level is a joke not enough fuel until 6K RPMs or higher.

425/425?

it will be a couple of weeks for the results, so please be patient. Also have an exhaust leak I need to track down. My guess is the exhaust manifold. I will look monday.

Do you actually hear the leak or are your logs a bit whacky? Good luck with it man!

Im still waiting for the turbo. I hope to god it arrives this week. According to BNR, hes still waiting on some special gaskets for the spacer to arrive.....sucks big time.

I can hear the leak. Fuel trims seem fine. Its got to be on the exhaust side because its holding boost so well. Just at part throttle I can hear the fast exhaust leak noise. It means its small.

EXCESSboost

I got some special gaskets in at about 4PM. Turbo will be shipped tomorrow!

BTW Term, what do you expect from a 91 tune? I know on my car the 91 tune just didn't do it for me, and I know my car is significantly faster on E. correct me if I'm wrong but 91 is awful for tuning and IIRC Brett's car was knocking on factory timing, so they reduced it to 8* of timing and still sometimes saw knock with 91, so...yeah....

HHRSSouth

91 Octane with Meth inj, should make for some good power.

^^^Great alternative for those that can't get E easy and have 91 Octane only or can't run E.

I'm getting ready to install a Meth inj kit on my vehicle in June and running 93 Octane because E stations are far and few between where I live.

If you're running out of fuel, try running meth to aid in the fueling. We usually run about 10% less fuel when running Meth.

Also.. raise the injector constant more.. all I will say, you can figure out the rest but you shouldn't have fueling issues yet.

Terminator2

If we are not past the injection limit on 91 octane at 28 psi I expect drews car to make ~430 whp and 475 wrtq currently. At this point adding timing is not making a big difference in acceleration at all.

cubaniche

iTrader: (1)

Awesome! Cant wait

tglems

iTrader: (3)

Right, but let's say you are currently at 22* of timing (or 18*, or whatever). Adding timing to go up to 26* may not make a difference in getting more power, but if you suddenly had to drop to 6* I'm sure you would lose a lot.

Edit: In this thread: https://www.cobaltss.net/forums/08-1...-100-a-251017/ the guy does a couple pulls, one on 93 and one on pure E85. E85 does a 60-100 of 5.2s, 93 does a 60-100 in 5.8s. I'm assuming 91 would do it in about 6.5 s. So, with the same tuner the difference between E85 and 91 is probably around 1s in 60-100 time. That is a helluva HP difference. I don't know as well as you do what to expect from the 91 tune, but I would be cautious of big numbers. If he put was able to put down ~400whp on an E-blend then I'd think that he'd be closer to 360-370whp on 91...

Terminator2

The boost levels are not the same nor the airflow numbers though. On 25 psi and E-47 with only 17* peak (it would start to knock past 11* midrange 17* up top) and 0.883 PE lambda it made nearly 400 whp on the mustang dyno (~430 whp on a dynojet) showing only 34-35lbs per min ve airflow in 3rd and 4th gear on my logs. Now on 28 psi E-47 is impossible to run. Even at 5800 RPMs we are well past the HPFPs maxiumum but even with that said it is seeing 41 lbs/min ve airflow and even on 10* or slightly less timing it will end up making quite a bit of power but I fear even on 91 octane we may be still past the HPFPs maximum. Just waiting on Drew to fix an exhaust leak and send me a data log on 91 octane.

its maxing out on 91 Oct @ 28PSI.... Runs great on the E30 blend!

Wonder what Full E on low boost would do?

iTrader: (10)

I see 4.6 to 4.8 sec. stock turbo 60 - 100 mph on the E47 with 5 gpm 50/50 meth. Same with or without the meth at 24* peak advance, just cooling the pistonies.

If he's still in the 5's with E85, there's more to get out of it. He may be maxing out the fueling and not know it. Anything over 60% E at 26 psi boost I start to lose rail fuel pressure and inj duty skyrockets.

His numbers on 93 are pretty close to what I saw, mid 5's.
