how good i a t70
 

how good i a t70 on a big port motor i currently have a t3/ t4 50-63 a/r's the t70 is 70-84a/r's how well will this t70 work on my block?

well the .84 should make it spool faster. there are a few people on here that are using the t70 with good sucess including someone that ran it on a half bridge at 19 psi and made 490rwhp however he had a 1.15 hotside. Do some searches. I'm running a mpt70 and am still putting the car together so I don't have any numbers for you but have done a ton and a half searches on t70's.

well
 

i am doing the research its just alot of turbos to go thru i dont want to spend a fortune i just think that my hybrid is maxing out at top end i think the efficiency is like 55% i am pretty sure the t70 has like a 70% effeciency and it will flow more volume.i just want to know if the t70 will make a huge difference?

lol, take a look at a t70 compressor map. The efficiency range is huuuuuuge. it will be a night and day differance between the two turbos.

well
 

i have often heard that people shouldnt use a t3 flange type for rotary i guess it doesnt flow enough exhaust volume what do you all think?

step up and go T4 :)
