is it true you can go to the 79 with out an adjustments?Just looked at your sig...yes, many people say the 85mm has no whine at all to it...We have a nearly identical set up except for the pulley...here is mine with the 79mm.
If I remember correctly the 85mm is the biggest pulley, which means the lowest amount of boost, which means lower whine. How were your numbers with that pulley?
Not sure but I would think not. Your talking 3-5lbs of boost difference. That's probably 60hp at least...new tune would probably be required.is it true you can go to the 79 with out an adjustments?
ok i thought i saw somewhere you can to like the 80 or something without modifications but they maybe just meant able to use the same belt.Not sure but I would think not. Your talking 3-5lbs of boost difference. That's probably 60hp at least...new tune would probably be required.
A 69mm with a 20% OD crank pulley should do the trick
buy a kenne bell? :shrug:

The external things like air lid removing or overdriving the SC for more Rotor Whine can make a difference on the outside on some however it usually changes very little inside the car. It's nice to have both a loud external whine and also be able to hear it inside the car, but that becomes very difficult on these new cars and SC setups, they just don't seem to transfer as much whine as the 2.3l whipple's on the 03 or smaller KB's on the 3 valves. The other issue with overdriving the SC is added boost and cal pressure starts to require high octane fuel. I've spent over a year developing a way to transfer more Rotor Whine into the cabin and have now a solid method using a sound tube I designed. It will without any other change but my sound tube mod increase the whine to the cabin by as much as 50-75%. Check out the reviews here. I have developed kits for 2010-2017 WHIPPLE, KB, ROUSH, GT500, windstorm and E-Force systems.Not sure but I would think not. Your talking 3-5lbs of boost difference.
