After changing the headgasket I was afraid to go to the track. New mods that I wanted to test: srt intercooler and underdrive pulley.
My previous best was a 15.119s, that was with stock IC, Grainger valves on MAP and turbo, boost set at 17psi, timing at 12°.
Now without Graingers the boost hovered around 14psi, timing was at 10° and ran 15.051s, 15.057 and 15.055s. Other mods are no balance shafts, AFPR, TurboXS RFL BOV, 17" wheels. This track is at 7000ft altitude (stock SRTs run 14.6s here). My best time did not show speed
but in other runs I avareged 145-146kmh (90mph), 60ft was 2.28s, the other runs also were in the 2.2 range. Here is the ticket: http://turbosmx.com/phantom15_05.JPG
I want to try boost at 18psi with the extra injector method, I already have the adjustable switch, but can not find any cold start injectors from Saab or VWs. 2.8 and 3.1 V6 Chevrolet engines do have them but I see nobody here uses them, should I try them? or raising the gasoline pressure will be enough?
