Since going to the Haltech ecu earlier in the year I have been wondering what kind of power the car was putting down. I had the chance to take the car to Equilibrium Tuning in Fairfield, CA and after everything was said and done the car put down 474whp and 381ftlbs torque @ 19psi. I am happy at the numbers but disappointed at the same time. I was shooting for over 20psi pulls but the car was breaking up and only felt clean at 19psi and below. I think the main issue is that I am still running the stock non gapable bur9eq's and should be running race plug 10's.

 

NICE dude!


Which BW you running, S366?

 

This was with the S360 .88 undevided rear housing on a HKS cast manifold

 

Even MORE amazing!!

 

Great numbers! How much water/meth?
Also, 420whp at 13psi?? Nice!
Power didn't look like it was falling much, why stop at 7k rpm?

 

This was with a single 600cc nozzle

I could probably carry the revs until 8000, but the power starts to drop just past 7000. I just don't feel the need to carry it past that. I change gears around 7-7500rpms

 

Is there anything special done to the engine itself?
Those numbers are impressive and frankly ..uh..I want them too..(haha!).Currently I got 357 on a stock s5 TII with a garret T04s.

 

I picked up the short block from Rotary Resurrection. Large street port, S5 thicker front and rear plates, S4 rotors, fd corner seals, ALS apex seals.



Current mods are

Haltech Sprint RE
FIC 1150cc injectors
Delphi 1000cc injectors
AEM 50/50 water meth
bur9eqp plugs
Jacobs FC1000 cdi
MSD wires
Walbro high pressure 255 pump
Aeromotive fpr
Borg Warner S360 turbo
HKS mani
JGS 50mm wastegate

 

do you know what your max duty cycles was on the injectors? I'm wonder if i should be moving up from my 1000cc secondary and primaries.

 

Duty cycles are in the low 90's on 43.5psi static fuel pressure

 

Does that ignition box make a difference?

 

I have been running the Jacobs unit for some time now. Here is an old thread that I started showing a little test I did with the ignition

20 more tq and the difference is haltech vs rtek??

 

More boost. When I was running the Rtek the stock map sensor only read to around 14-15 or something like that. So when I would turn the boost up to around16-17psi I would richen the last fuel column on the palm and lower the timing to compensate. Since I was running it like that I would have to either run it way below 15 or above it. If I ran 15psi it would have been rich.

With the Haltech built in map sensor that reads almost 22psi I can run whatever boost pressure below that with the appropriate fuel/timing maps

 

i've been trying to come up with way around the 15 psi limit of the tek. i was thinking a voltage splitter at first, but i would need a map sensor with double the range, and double the voltage, but similar scale to the stock FC sensor. like that can just be,,, found.
