when I went 10.41@135 on 93 octane at 32psi I was on the HTA 35R with a .63 turbine housing. I changed to the slightly bigger HTA 86, it still has the same 35R center section but instead of a 59mm billet compressor wheel it has a 62mm wheel. Also the turbine wheel and the housing are bigger. The housing went from a .62 to .82 to reduce that choke point in anticipation of running 40psi+ (still with me?) On pump gas the previous best was 617 and on the new turbo 633, not a big increase and it's slightly laggier by 300 rpm or so. However, it's going to be able to stretch it's legs at high boost. I stopped at 40psi on race gas with 701awhp because 1) my EBC only goes up to 43psi (3 bar pressure sensor) and 2) I ran out of q16. I still haven't bumped up the timing, it's on the dismal pump gas timing map, so there may be a little more in it. The knock sensor isn't picking up anything worth mentioning so that's a good sign. My goal is to go high 9's on the race gas tune. I hold the world record for the stock ecu/mas at 10.41 but I think carrying it with me into the 9's in full street trim daily driver mode would be cool.
Love the car man, Allways look forward to watching new videos from ya

Good turbo set-up! Im also running a 35r on my 2g DSM. With your power level have you thought of going with something a little bit bigger like a 37r or maybe a 42r? Are you running big injectors also? and have you run e85 on it yet?
