Cutting Out!

[JonTurpening]

Took my car to the dyno today. It did pretty well it made 327whp on a dyno dynamics at 14lbs. Had some problem with boost creep.

Drove the car home and about 1/2 way here it starting missing/cutting out when it started to hit about 10psi or so. It just all of a sudden started doing this.

Now when we had it on the dyno it did this and we regaped the plugs to 32. It did great after this! The plugs are NGK 6es's. I just wanted to know if it could be the plugs. I’m going to be taking it back to the dyno again tomorrow.

My set up:

RB25DET

JUN Intake manifold

90mm throttle body

550cc Low impendence top fed injectors

Garrett GT3582R

Tial 44mm V band waste gate

Apexi SAFC II

Apexi ITC

Walbro 255hp fuel pump

Aeromotive fuel pressure regulator

3" ss turbo back exhaust

FMIC

Z32 MAF

Any relative information would be helpful!!

coil packs

[JonTurpening]

Dang! I was kinda of hoping that, coils were not the problem.

It only does it when I get on the car. If I give it throttle nice and easy it will take it as long as I don't build any boost. Will coil packs do that?

get on the car as in "more boost"?

more boost = more air flow etc etc..

try budget option of taping up the coil packs.

search for "Tape+up+coil+packs"

it costs you 30 minutes and the cost of a few rolls of good electrical tape.

should give you some time to buy splitfires or something.

also, when you say you gapped the plugs down to "32" what measurement is that?

Yes. When it starts to see about 10psi or so.

Sorry, that’s .032”.

Thanks!
