Evo 9 + CBRD BBK Full turbo upgrade on 91oct and E85
Well I got my BBk full in last monday.. My friend and I got it a fairly good road tune in 4th at the local track today. AFR top end are 11.4-11.5 @ 22-23 psi. Track is @ 4500 ft. we only used 91 pump from shell..I managed a 12.2 @ 113.222. 1.6 60 ft 88 mph in the 1/8...love this thing.
To CBRD.. I've got a 50 trim turbo running on 28 psi with 100% alky. Max hp: 500@6200rpm, max tq: 447@4750rpm. It hits full boost around 4200 rpm. I want something that will spool like stock but will make around 500 whp. I'm a noob, pls. help what turbo I need for a DD car.
So I'm replacing it with a 2.3L, I'm sure we'll let you know what that looks like on the BBK. Build is coming to an end and will hopefully be in the car in about a week, so stay tuned

Brian came back in for a retune after moving to a 2.3L stroker, and oversized valves in the head (stock head ports still).
Car is now even more of a torque monster. Still on E85
Same peak boost as before (32psi) but 2psi less from 4500 to redline.
While tuning, the car hit 400wtq at only 24.5 psi, the same 400wtq took 32psi on the 2.0L.
huge gains!
