Found the above on boxanet.

$50K seems a pretty good price!

.....but 0-150,000RPM in 0.7 secs?
Typo?
or windup?

Thats the speed that the turbo spins.... don't think it it was refering to the cars redline somehow

Phew!

(......does a turbo really spin that fast!!!!?)

wadswoaj

Yep..... some have been known to get so hot that they can glow..... usually before exploding

Definitely a wind up, i used to have GTT F1 Hybrid Turbo fitted to a Renault 5 GT Turbo and that only wound up to 60,000 rpm and that could put out 60 psi easy (not that the engine could take that). A turbo which span to 150,000 would either have very shallow blades or be a wind up (They usually test Turbo's to 130,000rpm).

Second thing, there would be no point in putting twin turbo's on a car with an in line 6 cylinder engine, twin turbo's are for V engines with two inlet and exhaust manifolds.

I think the only way we will know for sure is if we all club together and buy it.

The Porsche Boxter is a flat 6 (Boxer Engine), it is easier typically to use 2 smaller turbos than one big one (space problems)

If you look at the Garret MAPS you will see that for a the smaller frame GT series fairly High RPM's are achieved, even a GT30R can do 120K+


On this link you will see that the IHI RFH3 turbo's max speed is 250 000 RPM

The fact that they say "self lubricating, variable geometry turbo's" implies that they are possibly using Aerocharger VATN units (which I thought were out of production ?).
