Added a blower cam to my LS3 C6 Picked up a blower cam. 224/234 .612/.600 113+3 Lunati cam. Tossed that in my LS3 and went from a 3.4" blower pulley to a 3.125" blower pulley on my T-trim. I figured the belt might slip being a 6 rib, so I put a Dallas Performance direct drive on also. Crank pulley is the stock 7.5" diameter. That puts the T-trim at max rated impellar speed at 6500rpm. At 7000rpm it's at 60,480rpm or 10% overdriven.
116F outside when we did the dyno. Intake air temps went from 120F to 198F during the pull and the ECU was pulling 4* of timing because of that. So total of 11* with 15* being commanded. AFR at 11.2 on the gas scale and 12psi up top. My stock LS7 clutch even held, lol. Not sure if it will still hold when I add a meth kit. Just going to do an AEM meth kit. Unsure if I should do a single or dual nozzle since I'll just be using the meth for IAT. I might be able to put more timing to it once the meth kit is installed, but with it pulling timing for IAT's we stopped adding timing.
stock cam & 3.4" pulley 604/515 vs Lunati cam & 3.125" pulley 673/584
