I am getting a rebuild and am trying to decide if i should go with the TII 8.5:1 compression rotors (which will be lightened and Balanced) or the 93 9:1 compression rotors. I need some Help once again on this


Pros of the TII rotors would be:
1.Stronger, unlikely to be damaged by detonation
2. can possibly run more boost due to the lower compression

Cons
1. still a little heavier then the 93 rotors adding to more turbo lag and less torque???
2. Would the car actually make less cranking compression? possibly making it harder to start

I cant really see there being any noticeable difference, and should definetly be able make up for the lag with more boost. the car was the perfect beast for me the way it was with the 93 rotors, but i keep denting them due to tuning issues. 60-1 turbo with .84 divided hotside, very large streetport and a aluminum flywheel are possilby relevant mods.

Can anybody shed anymore insight on this?
What would u do, or what have u done?

 

the more rotating mass you have the better the torque will be but the slower the revs ( general rule of thumb) either one will be fine so long as you have a good tune. But if i could choose, i might go with the lower comp ones.... i tend to run alot of boost

 

More rotating mass does not give you more torque. It only matters if your drag racing where you want to keep the momentum when you drop the clutch. There is no other reason.

yes sir

 

i've detonated the living daylights out of of my T2 rotors and they are fine

 

T2 rotors.
You wont notice any negative effects what so ever.
their wont be less torque etc.
You wont notice that the t2 rotors are heavier.

All the negatives you have put up, are just theoritical negatives. Most of them dont actually play out in the real world.
