if you want a nice powerband..... why dont you just use high compression rotors..... that way you'll have a lot more low end power, and spool up your turbos quicker

i'd also be concerned with the thickness of the rotor on that face, remember that they are hallow and have to tolerate some high pressures.



perhaps changing the shape of the dish would have some benefits, but making it deeper i'm not sure about. At least you'd be removing some weight, but hurting compression at the same time.



if it's an NA i'd say probably pointless, turbo and it might be interesting since you can make up for less compression with more boost.

lots of fuel needed for that, but it can be done

Okay, I'll just save the rotors until I need them in the future. If I were to use high compression rotors on a turbo engine, what would be the main problems associated with that? Will detenation be more frequent?

the 12a's have a different chamber shape, it tapers on the trailing side.

to use high comp rotors with boost you need to tune really well, or you'll blow the engine
