What injectors are you running and what are your duty cycles? Also, at what boost levels?

Reason I'm asking is for a comparison on my own personal setup.

 

ETS T4 35R, fully ported head, AEM EMS AEM Meth kit, 546 HP @ 29lbs 1000cc @60% from what my tuner told me

 

You would be fine with 880s.

 

i'd like to think so, but i'm running 1000ccs at 87% duty with 23 psi, and dual pumps! something is awry.

BTW about the same duties with cam2 and about 6 more psi.

 

554 whp on our dyno, just finished another car, ONLY 93 octane. At 8,000 rpm the dyno cycle is about 80% with 1200's and our double pumpers. This is typical, of course, as we build most of these high HP pump gas cars with about the same combination.

What dual pumps do you have?

 

full blown with walbro 255. -8 feed, -6 return. Aeromotive FPR at 46psi.

 

OK, good luck.

 

Do you see a problem with this as well or is this average?

I would appreciate your input

 

I'd appreciate your business

What HP are you at on what kind of dyno? What AFR's are you running?

I'd say you have something wrong. Should be easy to figure it out. Who is doing the tuning?

 

for what it's worth, DLL shows 526awhp currently, 30psi 93 octane

PTE 1000cc , BR twin pump 80-85% IDC

previously with 880cc, single walbro and kenne bell boost a pump 110% IDC

 

Don't tempt me, lol. I've been looking VERY hard at your camshafts, I'm tired of the 280's. Regardless, thank you very much for your input!

The hp I'm unsure of(at 24psi it made 470 on TTR's dynojet, on the hp61 turbo). I've been road tuning this car recently since I switched to a straight 35r. On pump gas I've been targeting 11.5, on the cam2(28psi 90%IDC) I was looking for 11.7-11.8.(I've decided this fuel is not that great...motor is quite noisy on it).

I went back and looked at some logs when I first had the car tuned after the motor build and dual pump and all that good stuff, at 32-33psi on c16 with the hp61 turbo I was at 94-95%!!!! So I'd say the problem has been there, its just now for me to find it.

Just as well on the stock engine @23psi the IDC's were about 80-81....that was with the stock lines and single pump.

Maybe the injectors I purchased were misrepresented? I forget where I got them from, I'm thinking dejontool...(like 2 years ago..)

 

Are you using the open source stuff to tune the stock ECU?
Do you have a FP gauge?

 

EMS, I have one on the FPR, but the local musclecar shop was closed today when I went to get an AN line to temporarily move the gauge in the car.

 

610hp at the flywheel UK HP over 90% Duty on RC 1000cc injectors running 3.5bar base fuel pressure, And the correct fuel supply .

BR 35R w/ HKS 280s (Id kill for BR cams btw), running 29lbs of boost and seeing 95-96% IDC. Im on Apexi Pfc btw.
