Thomas what size intercooler are you running
that it fits behind the euro front bumper? Also
what grill is that you have? Is it the kamei grill?

Weekend trackday, part wet track, was quite fun, no slicks, no fast laps, just fun.

Ended up with a N/A engine at the end of the day. No boost at all, really nice to drive home, it isn't directly fast without overpressure. Will take it apart soon, I suspect the big valve has loose the flap... and you know... parts in the turbo doesn't mean good.

Love the drifting parts The sound is brutal!

Yes it was. Haha, this was 650 MC so not so soft either. I will try to make a totally new design valve, now when I have a lathe.

Was that flat before????

Time to make a new one from Ramor 500

Ok, good news. Only the flap had fall off. But it's so big so it can't go up to the turbo comp wheel. Luckily no bolt hadn get loose either, only the small washers had been eaten thru. Why the turbo didn't start to rise the boost was because my dump valve is so loose theat low boost escaped thru it. And of course I didn't test any big rpm's/high boost because something was broken. 1.6 bar has leave the mark on the flap, I was quite suprised of this.

You thought about water/meth injection to control inlet temperatures?

Well, I have some plans... Don't know if I will go with the radiator in trunk way or not. It would let room for a big size cooler though. Water/meth inj. could be nice, but I don't know yet...

Thomas you need some good tires my friend lol

Yes. Wheelspin was great espeacilly with first gear. Tyres are brand new "made in singapore" Gerutti LPR 728 235/35R19. Cheapest one I could find.

[mushasho!]

Lower the pressure in your tires to avoid wheelspin... i use about 22psi and it allows me to cut consistent 1.7 second 60ft with half the power you're making.... this should be a deep 11 second car with that ~117mph trap speed...
