ok guy I dont want to get in this but come on do you think Matt would take all the time out to make up these numbers?
My car is on full E and I picked up 21hp. Matt never had a problem or anything....I am sure BYT and TERM have done a lot of tunning BUT I am sure together they have half of what Matt has. Matt wakes up everyday and tunes/works on cars. he loves it so much he stays after hours and works weekends. Also when and If Matt cant figure somthing out he has Ryan and Tim there to help. Come on Matts been doing this for years. just saying

Im not even arguing with them but before you speak for people you should at least know what you're talking about. I tune these daily as well and I spend a real lot of hours not only tuning them but working on them and creating new parts for them as well.. Im not just a guy behind a PC, I own a shop too
in the end tho its always good to see new shops open for the Cobalt world.

Lol, it's not just the octane that matters. Obviously there is more power to be made with Ethanol over gasoline, otherwise we wouldn't be doing all this r&d to figure out how to effectively use Ethanol. Let's not get to the point where we say that it's only 47% E, so it's not really doing anything. We all know that most of the gains are in by that point. By comparison, we dyno'd a car yesterday that put down 304 on 93 and 327 on E70 just poured in. This would put it in the 50-60% E range at the most. Yes, Ethanol adds that much power.
On another note- I have never bashed the 2871 or said that you won't be able to make more power if you add boost, add timing, etc... I only said, "We need more data before I would accept the 75whp gain claim." After going in circles for a while, you point out that you could change a couple things and make more power. Well, gues what? If completed successfully, that would be more data! What we have now is more predictions, which is fine for discussion, but should never be stated as fact until actually achieved. Do you see what I'm saying?

I have 2 cars that gained over 30 whp going to E-47 from gasoline on the stock turbo so what? You are a perfect example of my argument though. Your car made ~40 whp and 60 wrtq less than their shop car on E-85 or E-74 or whatever you guys have up there. 40 whp is a big difference on the same dyno and just turning the boost up on the K-04 will not lead to more HP up top. My whole point is 360 whp and 420 wrtq on a properly reading mustang dyno is past the injection limits for the stock turbo on E-74 or E-85. Actually it close to the limits on E-47 and the stock turbo. Only their shop car has made their claimed numbers on E-74 and the stock injection system no other cars that I have seen that have been tuned there have been tuned there seem to come even remotely close to their shop cars numbers on gas or E-74.

You have about the same amount of boltons, airbox mod, cps, IC, catless DP. I thought you made ~310 whp 366 wrtq before the E-85? I had read your sig before. IIRC he is is not running a built engine ( I know it had stock head, stock cams and stock fueling system) and he was running ~24-25 psi ( maybe spiking higher but the boost and power will fall off up top with the stock turbo no matter how high you crank the boost in the midrange)

It is making more power now but his HPFP cannot keep up even at 5700 RPMs with the E-47. We are going try 91 octane to see if it has enough fuel to support 91 octane at its current power level.

The crazy part is it is running out of fuel at 3,500 ft above sea level where the baro pressure is only 90 kPa (13.0 psi) and in hot weather (80-100* temps). At sea level where the baro pressure is 101 kpa (14.6 psi) and cooler air temps it would be running out of fuel even sooner because he extra airmass/fuel demand. If I could get enough fuel into it with the E-47 with its current tune I believe it has the potential to make 430 whp and 470 wrtq at 28 psi on that same dyno.

Again the first company to come out with a HPFP upgrade is going to have the market as we dive deeper and deeper into bigger turbo set ups that need fuel.
No offense to ZZP but I don't want to run another rail, etc., I want a bolt on HPFP.

this has to be one of the most informative threads on css to date it actually saved me some money almost ran out and got a turbo listening to an idiot and didn't know all the fueling issues with our cars

So, I dont think the regals HPFP is any different than ours since its only trying to achieve 255hp on regular gas and E 85 as well.

This X10000000000000000000. I also find it funny that zzp made 509 whp on a dynojet with their S-252 and yet everyone I have seen dyno there ZZP kit with the S-252 has fallen 100 whp short of those numbers on dynojets. One-252 car made only 350 whp on a mustang dyno at 22 psi on 93 octane here in florida (I did not tune said car).
509 was on gas. DI only.
