high conmpression turbo builds?
I was curious on how people's high compression turbo builds have been? I know lately a lot of guys with cyl engines are going from the low compression with tons of boost to higher compression with less boost.
The topic interests me because I would like more response. I recently built the block on a supercharged e36 bmw with even higher compression forged pistons and rods, and the thing has awesome response now!

My job is to blow **** up

ran 9.7 to 1 n/a rotors on a stock turbo FC on 87 OCTANE at 12 psi to boot. timing was 14 degrees advanced 6 split at were torq peak should have been. full boost by 2200 rpm, eventually a vac hose going to the map sensor blew off... the block did not survive. probably going back to 9.4 s4 rotors, as the s5's are too pricey and expensive. s4 n/a rotors are the most common.

What negative and positive effects do you have running n/a rotors on a turbo engine im curious? I heard someone tell me that but did not believe them because i thought you had to use low compression rotors on a turbo engine

I rant a turbocharged Renesis (10:1) for 4 years and managed to get 518whp @ 19psi on E85. The problem with that engine is the exhaust geometry/layout which is prone to causing detonation etc. I think Renesis interiors on a REW or B-RE engine would be an interesting combination...ie. more power with less boost.
Cheers!

I'm wondering if there is more reliability with more weight of the rotors. I know the rx8 rotors are light, I'm wondering if thinner materials would mean less strength.
I was reading how the rotors on s5 and up are made with a diferent process. How much more strength is there

Our FD LeMon makes 330 hp at 10 psi-ish:
Half bridgeported.
S4 NA rotating assembly
T04B ebay Ching Chong turbo
3" exhaust
Power FC
850 pri / sec injectors
Walbro 255
Home grown V-mounted intercooler / oil cooler
I'm totally sold on this setup and when my other FD pukes its innards, its getting NA rotors too!
You can make more with less.
