we have been to the track 5 times and the dyno 3 times. one trip to the dyno we made 34runs. we have around 150runs on this set up between the dyno and the track. at least another 30 hard runs on the street. at least 50 full runs at full power of around 600rwhp.
the motor makes no smoke, no funny sounds, idles smooth and quiet and uses very little oil. since the track made us remove our front exit exhaust we dont have any crank case evac at all, just a valve cover filter and strangely there is no oil coming out of that filter at all.
our exact set up is a junkyard 5.3 with unknown miles that was siting in the corner of someones garage for at least 2 years. zo6 cam, decent valve springs. mp70 turbo, ebay intercooler, 50lb injectors, single gss392 with boost a pump. turbo400 with a stall that flashes to 5000+, 2step and brake.
even if this thing blows up tomorrow i feel like we have shown how strong these things are when tuned and fueled properly. in a stick car i bet we would be over 700rwhp on the dyno.
