My buschur racing pump gas evo
I'd like to actually start a new thread but since we are all here argueing already.........
I tuned two GT35R's in the last two days. Very interesting. Both of them were EVO9's. Both of them were atleast somewhat interested in having me try to match Trent's pump gas numbers. Neither car would even come close.
Maximum boost on the one car was 26 psi, the other 23 psi. Both of the car very prone to detonate and I had to stop.
Both cars were running 93 octane that was purchased in Ohio on their way here.
One had a TT header on it with a PTE 3582 turbo, the other had an ETS 35R on it with a T4 housing on it.
The car that should have made the least power made the most and was able to run more boost, it was equipped with stock cams and the stock intake/tb with the T3 housing 35r on it.
The car with the T4 ETS 35r on it also had Cosworth cams and an AMS intake manifold on it. It was horrible and knocked very easily.
The car with the T3 35r on it had an ETS FMIC on it, it did a pretty good job of keeping intake temps down and this has a lot to do with running big numbers on pump gas.
The car with the T4 ETS 35r turbo kit on it should have made big power from the T4 housing but was equipped with a Perrin FMIC that was gaining 49 degrees of intake temps in a single gear pull, so it killed the power potential.......
Not sure how many time I have to type it or say it but if the combination isn't right then the power isn't going to be stellar.
These were both two well put together cars with no problems. Not a drop of oil, water, boost leak or anything else. The guys did a great job on putting the cars together but in the end the power just couldn't be made.
Actually, the car with the stock intake/tb and cams did pretty well. I ended up making 515 on race gas which is pretty darn good. It could have however made substantially more had it not been so knock prone.

Interesting Dave and thank you again for sharing this information.
I hate to think how much you know considering the little you post on these boards, if only I could make a living doing this stuff!!!! Besides AIT what else specifically do you feel increases the knock threshold(boostwise)?
Thanks!

Those are just a few. Hard to dig them all up via search. There are plenty.

Also I keep asking... how are you listening for det? Just curious what type of gear you use to help me with my own stuff.
What increases knock?
Octane.
ANY-ANY-ANY restriction in the engine, whether it's in the head, intake tract, intercooler, turbine housing, 02 housing or the exhaust system itself. That is the key to making power on any engine, make it flow air in and out, its pretty simple actually.
High intake temps both at the air cleaner coming into the turbo and the outlet temps on the intercooler.
Of course there are just odd things that will cause it too, maybe a hot spot in the cylinder head, wrong heat range plugs etc.

I stopped looking at those threads when I saw that one was using the Optimax Shell fuel which is ~98 octane.. And others had superunleaded which is at least 97 octane if not more.
Octane too low increases knock.
I rely on two things when tuning, one is the factory knock sensor the other are the torque numbers on the dyno. I also have a chassis ear for listening but rarely need to use it. I use it more for finding problems than for tuning for maximum timing/torque numbers.
EVO7, the Power FC is an EXCELLENT ECU. If it weren't for it's few limitations that is probably what we would use almost exclusively. It is on my brother beater EVO, he ran 121 mph traps on an EVO Green last Friday night on 93 octane, he is running 28 psi of boost on 93-94 octane fuel in the car. The ECU performs flawlessly. I keep trying to get Apexi to put in a few features it is missing though.
