Thread: Slug finally ready for dyno.. motor pics

    I was not planning on building that much boost/power. I was running a 5" Blower Pulley at 6lbs (738hp). I switched from a PC 324 IC to the larger 504 IC and wanted to try a smaller pulley . My 4.75" did not fit so. They had a 4.25" at the shop so we put it on. We tried a pull on the dyno and the dyno was set to low so we backed off. When I saw this I chanked up the fuel pressure from 60 to 75lbs, this made my little 55lbs Seimans feel like 72 lb per hour. The DC was 100% by 6700 rpm and got a little lean 12.5 A/F by 7000, approx 576lbs of fuel. This was the only pulley change I had while at the dyno. It was one quick pull. Waiting for larger injectors. I'm switching to a larger pulley 4.75" or 4.5" don't need that much power..
    The TB is an old Cutler, like the new Holley, 1000cfm.
    I'm going to run 72lbs @ 60 psi.
