Okay listen up... I dont need you to tell me that I am stubborn. I know i am uninformed...obviously that is why I am asking around. I am just relaying what the rotary shops have told me. Get that through to yourself.

You have NO clue what your talking about. People like you spilling misinformation on this forum are bringing it down. Demetrios K. and myself both use stock 2 piece 2mm seals. He has boosted upwards of 45psi with no damage. Its all tuning. 3mm seals will make less power and when you detonate they will break just as easily. If you don't want people to call you out, don't post on a thread when you have no knowledge of the subject.

"and 400WHP RE will feel much faster than any 400WHP piston engine car"


Hp is HP. Sorry to burst your bubble. It doesn't matter where it comes from.

I was told by local Japanese shops not to run over 1.4bar with good tuning on stock seals. Thats all i've ran and haven't had any problems. i would also look into running twin walbro's. Since you already have one. No since pushing 1 pump to it's near max. It's not that hard to add another intank pump.

This I have to disagree. let's talk about DRAG first. what is the first RWD to brake into " 9." in japan. A Purple FC with Twin HKS GT turbo. make about 700HP or under it . but check out other RWD CAR. like SUPRA they make like 800HP+ but still cant brake into 9 at that time.

RE rev faster than Piston engine and respond better to. that what I mean it will feel faster..
No mater in any type of race if piston and RE got similar HP. RE will most likely win ..

Your not puting in a factor of weight or traction on your claims. Supras dont pull good times at the drag strip due to there very limited traction and there very peaky power band. Not because they are piston motors. One of my friends brother has a 68 camaro that is only making 600 and some change flywheel horsepower that is running in the 8s. His car also wieghs 1900 pounds and he is tubbed and uses huge slicks in the back.

I somewhat agree, but when mentioning 45psi, also mention race fuel. Stronger seals will resist knock. Knock knock knock.

3mm apex seals are not a must trust me. Boosted over 30psi on GT4088 RE and a q-trim T70 REW, both are fine. Then again I saw a fully built REW with 3mm apex seals, blow up at 14 psi (T78). In my humble opinion, it all comes down to the tunning, even though 3mm seals help some what (marginal amount).
