Anyone every experience what appears to be a cut out at WOT? I run through the entire RPM range as long as I don't put the pedal on the floor. Here's my setup.

13B Street Ported Race Motor
Garrett T04E Turbo
HKS tubular manifold
40mm HKS Wastegate
Custom 3” exhaust
HKS additional injector controller
Aluminum Radiator upgrade
MSD 6al ignition
Nology ignition wires
NGK plugs
Blitz Dual Turbo timer II
Tokico suspension
HKS SSQV BOV
ACT clutch
Short shifter
#1 3” Muffler
Turbonetics Boost Controller
MSD 750cc Injectors x 2
MSD 1000cc Injectors x 2
Custom Intercooler piping
HKS style FMIC
255 Walbro fuel pump
S4 Intake Plenum; lower & upper

 

What kind of fuel management system are you running?

That's alot of big fuel injectors you have there.

I would imagine that a setup like that would have to run a standalone, and in the tuening of said system lies your problem.

I really don't know **** about forced induction or aftermarket efi, so I'm shure I won't be able to help. but good luck.


Very nice car.

 

May have to make that my new sig.

 

What I experienced was different. I would floor it, be fine through first and second, then when I hit third it would sputter out like it was flooding out. I'd shut the car off and I realized that the carb wasn't closing, causing fuel to just dump right into the carb and it was flooding out the engine under hard loads. When I finally stopped driving it I was having to readjust my carb three times a day just to make it home. I wouldn't rule out the possibility of too much fuel over not enough fuel considering the amount of fuel that could go through those injectors.

Oh yeah, and let's see some more pics of that car.

 

Go to my web site on cardomain

 

 

I see no fuel management or standalone listed in your mods. If you have none, I don't see how you make any power once the secondarys come one. Gotta be pig rich.

Any wideband/dyno tuning done?

 

What type NGKs, heat range and plug gap are you running? How much boost? You could try a smaller gap to rule out ignition issues, although the MSD should be able to fire even a large gap under boost. I have not owned Nology wires but I have a few friends who had issues with them. Maybe ohm out the wires? If none of this helps then A/F issue is likely to be the problem. Do you have an A/F meter/gauge? Do you have access to a digital VOM? Use the VOM to see what the O2 sensor is doing. That should give you an idea of where the A/F is.

 

HKS Additional Injector Controller is my fuel managment. I still run the factory ecu to drive the primarys. A 1st gen only runs primarys. While normal driving, the additional injectors are not needed, just as a 2nd gen is set up from the factory. The HKS AIC is fully adjustable on the fly and will supply more than fuel to compensate.

 

but how does the stock ecu know that you're putting more fuel in? It's not giving it more air to go with the fuel... That's just my take on it, I could be way off, and seeing now that there's a turbo involved...
