for the sake of discussion - ive experimented with 2 different cars using 2 different pre-turbo water injection configs and a couple different nozzle configurations. both lost quite a lot of power for me. While i am sure that every setup is different there is a reason that the AEM guys mutter under their breath "you can run straight meth in our system"

Shaun and Elliot have talked me into getting this little hairdryer for my 91....
I'm running on 15 year old Knightsports stuff and the car has always been rock solid so the fixing what aint broke part has me a bit nervous. But, the flex fuel option, E85, IWG, IBV, cast manifold, ID injectors, adaptronic...all add up to a modern package that i expect will breath some serious new life/fun into the car. I'm sure i'll find out quickly that a 235 rear tire wont be nearly enough...
Here we go...it should be done just in time to stick under a cover for the winter

S363(aka s362) setups I have tuned make a tick less power and a lot laggier than the EFRs.
On a side note another customer of ours had made 426rwhp at 15.5 psi on our EFR IWG 8374 kit. He has 3 inch exhaust, a ported motor and is on E85. Adaptronic pnp is being tuned by Luke at Redline Perf. Higher boost pulls to come.

here are my dyno graphs with the same turbo and manifold as Elliot posted above (mine is at 12psi with medium street port engine and rich tuning):
the slight dip in torque is from tuning.
the torque curve is VERY broad with this turbo setup. i got the turbo and manifold via Turbosource/Turblown, and i highly recommend their kit.
scales changed to look a little more normal:

Im running a street port at 12psi and rich tune also. 338 with a tdx61 on a dynotech.
Cant get too much more safely on donkey fuel, but with a sniff of meth (and a diff upgrade) the sky's the limit. But its just an fb, dont really need much more power.
Just chasing more throttle response really. Tossing up whether to go 7670 or 8374.

Hi Jacob. Are the dyno pics you posted here still available? And how did you find the 8374 at that state of tune? Would it be possible to describe it as N/A - like throttle response at all?

Hey Elliot, I know some Ecu make a difference when it comes to tuning, I saw only see 1 tune with power fc with the 7670 setup. However can the power fc with the 8374 IWG setup make similar power like the adaptronic Ecu? I am trying to justify if I need to replaced my ECU.

Dyno starts right around 4,000rpm.
To me it looks like this car has slightly taller tire than the usual 25" (25.4") or 8,100rpm redline (which would be weird).
Would like to see 2,000-8,000rpm sweep on this because 4,000-8,000rpm doesn't show the EFR 8374 strengths compared to the usual GT3582R turbos in my opinion.
Thanks for posting what you had though!

I have another dyno sheet of a car I remotely tuned. It was tuned on pump gas only. The owner hooked up and turned on the water/alcohol injection for the dyno. It is an 8374 IWG FD3S with a 3" exhaust and large streetport.
@ 17.25 psi it made 440rwhp/371rwtq running mid 10s. No RPMs on the dyno sheet and the car is now parked for the winter. It would hold 10.9 psi with no controller on all the way to redline.

I don't want to run e85, and all i have here is 91 octane and 50/50 water/meth.
