ok yes i have stage 2 ported foxlake (modmax) heads and port matched lower intake. larger valves w/ stock cams. stepped long tubes w/ 3 inch exhaust x-pipe and 2 3 inch dynomax racemagnum ultraflow mufflers dumped in front of the axle and a fuel cell were the spare use to be(removed stock tank). STOCK BLOCK (gonna run it til it blows). the eaton is just about done. if all goes well this winter the truck will have a turbo on it by next spring. my truck was dyno tuned on a mustang dyne (puts real world loads on the rollers unlike a dynojet) my a/f's are 11.3-11.4 and i have a uego 1000 air/fuel meter on my steering column and watch it every pass. and my truck has never been a daily driver and in the last 2 outta the 3 years ive had i've only put about 1000 miles on it mostly at the track.John M. said:
rdy2rac, Whats the reason you are seeing only 15#'s with 19#'s of pulleys ? Im assumming that with that much boost and timing you have a built bottomend, are you heads also ported or is belt slipping that bad ?
