the car was completely done and running and down at cincy speed for tuning.Tracey got a little bit of street tuning done on it and said it felt really strong but the car kept getting hot after running for a while and some other odds and ends
So i brought it back to the shop and cut out the front end, moved the IC up about 6 inches, leaned the radiator way forward and redid the braided lines getting rid of some non ideal routing, added in the remote coolant fill/cap. fabbed up some tubular bumper supports, dzus tab bar, tubular lower radiator xmember, and lower ic support. Bought a nice turbo blanket for it, 3 bar map, and a dual stage MBC. thinking about redoing all the vacuum lines with instant fittings and nylon hard line too while im hooking up the new boost controller

finally started making some pulls on the dyno. first pull had a coupler blow off and shut down made 446 rwhp@ 3300 rpm
got it all fixed up next pull heres what the tune looked like
18* initial timing with it sloping off linearly with boost, 11:1 AFR, 16 psi, rev limit set at 6300
results: 611 rwhp @ 6300 rpm
tune is super safe right now still on straight 93 pump.The cars got a single plane, big solid roller setup, and afr 227's so its meant to rev and breath. Gonna lean on it a little more next time around and take it to 7200 rpm
shooting for 700-720 on pump to keep it safe. then gonna switch to c16 tuning.
this is through a th400 and 9'' too. Right now were dealing with some intermittent charging system problems not keeping a solid 13.5v all the time. trying to get that sorted then its back to tuning
