The old girls still running hard got it up at 23psi on 14 degrees making up for a loose converter.we twisted a b&m nitrous hotshot converter and it wouldn't stall up at all was almost like a clutch little bit of throttle and it would stop slipping couldn't get past 1500rpm.fitted a used 6500 rpm hughes converter out of a big cube big block methanol supercharged car that came up cheap.makes launching a breeze roll in hit the transbrake full throttle and it's at max boost near instant but it has put us up past max torque and max hp rpm and cost us a few mph but can roll off the trailor and run 1.5 60s and 10s every pass very easily now instead of battling to get in the lights and get it on boost.
Also fitting a 1.06 A/r single entry t3 turbine housing on in place of the 0.84 twin scroll to try get rid of some backpressure as every time we add boost max hp rpm moves lower so trying to get some more grunt up higher in the revs .it's currently running 3.08 diff gears and 27" tyres to get our mph back from the loose converter as a bandaid
