I agree with you Ralph. The numbers and the circumstances do seem odd.

Rereading the OP, the car run out of fuel at 317hp and 425tq with the stage 2 injectors. At least that is what I see.

yeah I went and re-read it as well. It seems like an improvement over stock. Carries boost and the torque spike out a bit further before it dies at read line. Now I'd like to see the timing, and the knock count with the knock sensor actually hooked up.

LOL

I would like to know how much more this turbo flows vs a stock wheel.

Stock is 32? Lbs/min while a E1 is like 37.

This turbo is still technically a stock wheel with a extended tip and billet.

I think another problem is the review could have been drawn up better. Information on the car is kinda scattered. The read is a little confusing.

im just the messenger guys. he sent me this


Please forward this to the srtforums thread:
"RHunter: Nowhere did we ever claim it holds 25psi? I openly stated in the write-up that it drops down to 16psi by 6000rpm. You can clearly see the car is hitting 28psi and there's no knock from it. The only blip of knock you see there is where the car is leaning out.
Chicagoskittle: 104-108% injector duty cycle...leaning out...all signs of not enough injector.

If anyone has any questions, you're welcome to email me at matthew.cresto@gmail.com and I'll answer them the best that I can.

I'd like to see the IAT on that pull, but only because I'm curious. The facts given are pretty decent and not unbelievable to me. A 1:1 regulator or larger injectors should be safer, but there's nothing showing that it would or could make any more power with them.

Its seems to make good power but still has the same flaw the stock turbo has. no top end. at least with a bws or E1 u get better topend. and Certainly the exhaust manifold makes a difference.

Is that post intercooler temp or pre turbo temp? I don't know what their designated acronyms are on the srt4, but I was wanting post intercooler temps and that doesn't seem to be accurate unless it's in Celcius or pre turbo temps. I don't remember seeing what intercooler(I'll go look again), but I believe the stock IC wouldn't do that well or te pull wasn't at sustained rpm for long enough for temps to climb much. It's simply hard to believe a stock turbo running that much boost has as low or lower IAT's than my car with a DBB Delta65, 28x12x4" IC and WMI.

Is there any WMI injection before the IAT sensor?

It states that it has a Godspeed FMIC...not sure of the sizes of those. Celcius seems plausible though. 57*C=134*F and 70*C=158*F

Ok, I registered so I could answer the questions directly. My appologies to rrodney24 for him having to be a messenger, lol.

The temps are all in F, there is NO water meth injection on the car, and are POST intercooler. Ambient temps were between 57 and 61 degrees.

Here's the datalog in a spreadsheet format. I've seen several people ask for timing numbers....come on now...no tuner gives away every detail of how they did something...

https://docs.google.com/spreadsheet/...004U0J6cHB0bkE

keep the questions coming.
