The Official Centrifugal Pulley/Boost Combo Thread!!!

[SVTPete83]

Beast mode Pete!! Great freaking numbers man!!

Nice gains there Pete! Bet it sure is a kick in the pants when the boost starts to ramp up.

Thanks guys! She sure pulls way harder in the midrange. My average HP and TQ both went up over 30 each. The t trim seems to grab boost much sooner then my old s trim. Good times for sure. 10 second slips are in my future!

11. Yes Powerpipe
12. 449/413 @ 5800 rpm with 9° of timing on 91

I didnt realize the tech stopped at 5800 on the dyno till it was to late. Always wondered what it would have dynoed at the 6700 redline.

Current setup is still in build progress. Will post once complete.

Changes - mmr shortblock and 18psi. Made 513/504 @ 6k rpm in a 100 degree shop hitting 150+ intake temps. I'll probably go back in winter to see what the difference is.

Get a 10% OD crank 3.125" pulley and you have the recipe to hit 600 to the tire. You can get it done with the PI intake manifold.
