If a stock Greddy turbo will make 250-260 comfortably on a MT then it will make 220-230 easily on an AT . Just need to wind up the BOOST mon !

Also : you won't need the fuel pump - but a good upgrade all the same .
Suggest you mount an extra rad where the 2nd oil cooler would go to get a handle on engine temps .

Nope. Jim has major plans for that car. But from what I heard...he is very interested in using an AP to tune it. His car is setup with a custom turbo and NX nitrous system. We'll see what it does in the future.

I'm just happy it runs so smooth and kicks you back in the seat lol.
Congrats!
I agree with Jeff, there' room for improvement in those #'s.

PING PING -- I detonated, we think twice when we got back on the dyno after everyone left.

We had thought earlier in the day that I may have a fuel pump problem... @ WOT I was running dangerously lean right around 6500-7000 RPM. It'd be fine up to that point but right around 6500 it was shooting up real bad.

So we had the dyno operator and JPR Jim construct a improv fuel pressure gauge and thinking we'd see a fuel pressure loss. Well pressure held solid at 60PSI all the way up to the point fuel leaned out again and then there was this all to subtle *twink* sound. Made a couple more changes to the map and tried again... ran even richer up to 6500 and wouldn't you efen know it, it *twinked* again.

Current thought is bad injector. Car doesn't feel any different but it was a smidge disturbing to hear detonation. Will have to keep a close watch over things as I await injector cleaning/replacement.

That 180 pull wasn't at full boost either.

Have run to 13.5 at 13psi when I experienced the dreaded ping . Below that was OK .
What was your AFR . You suspect one of the P2 injectors ?

Damn, how was the car running home? I'm going up to KDR tomorrow so I'll be able to get the engine cover for you. I'll see if they can get upgraded injectors, and a estimate on the new cooling layout Jeff suggested.

He doesn't have P2s - it is a 4-port auto.
His AFR was 11.7:1.
I think the AFR reading was an aggregate of a very lean rotor and a very rich rotor, caused by a secondary injector that is under-performing.
I was commanding 8.5:1 to get that 11.7:1. The other 4-port auto turbo was not so problematic in this regard (though it would sweep from 190° to 236°on a single dyno pull).

I guess the only practical way to check that is flow testing the injectors . Come across this before ? Seems unusual given the accuracy of the stock injectors
