Roush S/C Pulley Options

[Doctor Fishtail]

I have basically the same setup plus the vmp 67 throttle body and long tube headers and it makes a world of difference. ken is the man.

Is the blower whine more noticeable with this smaller pulley? And how many lbs. of boost are you getting? Also where did you buy the 79mm from?

Couldn't tell you. I have long tube headers with corsa extreme catback so I can't here any blower noise. I got it from vmp performance.

LOL. Yea after I posted that I thought he is gonna comeback with "Are you kidding I am deaf after running this exhaust setup :lol:" Thanks. Boost #s?

Any reason you guys are running smaller pullies than 79? Just wondering thanks.

If you run smaller than 79mm, you will need fuel upgrades as listed.
Would surely be a beast though.

I have 75mm pulley on. Lund gave me a tune for it with 93 and a tube for it with torco. I did have to put a smaller belt on but making 14psi no heat soak issues or anything. Mods in sig.

No I just went to advance with the belt asked for next size down which was an inch smaller installed it and instantly felt the tension difference. Trying to find time and money to get back out to dyno but pretty sure I'm in the 700rwhp range
