03 track model w/ vortech v3sci . 600cc injctrs, 340 aero Fp, cjm stg 2 frs, uprev maf, Osiris tune, long tube headers no cats Borla exhaust, jwt flywheel/clutch combo, 2.87 pulley 34/28 cog, treadstone IC, built bottom end, stock heads cams valves etc, snow meth kit, making about 11lbs, but only 475whp and 415lbs of tq. I was making this before on a 2.6 pulley and 32t cog...with the stg0 cjm system.... any thoughts on why there's no increase in power?

Assuming the main variables changes supercharger wise was the 32 cog for a 34 and you went from a 2.62 to a 2.87 your actually are spinning the blower slower(less impeller speed) so it should actually make less power then you made w the 2.62 now as far as the meth that's all on the tuner

Go to the Vortech calculator and you will see what I mean. The 2.62 and 32 cog actually spins higher than the 34 tooth and the 2.87

Right, I new it would but I couldn't get the 2.6 to stop slipping which is why I went from 9lbs on that to 11lbs on the new setup...so couldn't I throw on a crank pulley or the 2.6 and make more power
