Great results - can't wait to see what the 3.3L does in comparison. What is the stock pulley on the 600sci? I am almost certain tha tthe 700sci comes with a 4.0" from and stage II is 3.75".

Can I recommend making a chart (excel style) to summarize all the diff stages, options, hp/tq, as an easy reference guide. Also maybe start new thread with results for easy to find reference!!!! Great Thread!!! Great Results!!!

Dustin, Is there a gear reduciton on the blower or is it just one to one? Assuming there is not, when I multiply my pulley ratio times my max rpm's, I am only at 75% the maximum rated blower speed. Since the 3.3L is not maxed out, are there any advantages to going with a 4.0L other than lower air intake temps? Using rough calculations, 2,000 cfm should be good for at least 1,000hp.

Update:
The motor made 905 hp at 6100rpm, and 855 ft/lbs of torque.
This is with a stage IV setup: reprogramed PCM, Whipple cam, 4.0 supercharger at 13 lbs of boost.
Dustin feels that boost is once again stacking up in the intake manifold, and not getting into the cylinders, and that the heads are now the limiting factor in the equation.
The next step is stage V modification... ported cylinder heads. The heads on the 525, 600 and 700 are all the same, and specially designed for their closed cooling system. Dustin feels that with opening up the heads, he can produce the same horsepower and torque with 2-3 lbs less of boost.
Of note, Dustin discovered that once this motor starts flowing enough air to get over the 750hp mark, that the stock air cleaner is reducing power by over 20 horsepower. He is in the process of building an new billet air cleaner for 600 and 700 sci motors that will be a nice addition to any 600/700 motor owners looking for some added bling and performance.
