Question Differences between T66-T72 and T-78??

Can someone tell me the difference between the T66-T72 and the T-78? specs and hp capabilities please. My mechanic is swapping his T3-T4 hybrid for something much larger and asked me to get one for him so I am wondering the differences cuz these seem to be the best for big power on a third gen.

Lookin for about 450rwhp at 15 psi with a ported motor.

Thanks

Hey, I don't know where to find compressor info on mitsubishi turbos... just search the net. Here's a good write-up on some general math for picking an efficient turbo setup. Obviously you'll have to fudge some, 'cause it's not designed for rotories, but it'll give you a general idea. Look at the compressor maps for the turbonetics turbos, and check the efficiency at or around 15psi....

Remove the ".5" from the formula, and it will work for a rotary engine just fine.

Yeah, I was thinking that... What about VE? I thought it was alot less efficient for a rotory.
