I was just about to buy a JT trim blower the other day when I thought to myslef that I have yet to max out this T trim So when I get back from my Trip Im taking the GT back to Kurgan for some other upgrades. While im there I want To pulley down and retune. right now im running about 18 PSI at around 6400RPM on a RR 2.9 with Zero Slippage. Since I converted to E-85 I want to take advantage of the extra octane and spin the Blower to about 21-22 PSI who has done it and on what pulley? Im already running a 10% overdrive and I am just going to keep it rather then upgrade that as well. Right now Im at 600RWHP so Im thinking picking up about 4 PSI will put me around 650ISH and Then my project will end cause It time to concetrate on my new car that I purchase in the next month or so.
