ROUSH/VMP - WHAT PULLEY DO YOU RUN

[Dntalman]

I run a 79mm now and think I am going to change to a 69mm and run a Hasty bracket. List what you have and if you know your boost amount. If you would like a different size, list what size you want.

82mm wasn't an option in the poll. That's what I run on the vmp g2r.

Sorry about that. I meant to add that size.

My stock 85mm pulley with my Lund tune and Kook's headers is plenty enough HP for me. I think they said I was at 8-10psi? Either way, I'm not really feeling the desire for a smaller pulley. Lund did have me get a fuel pump booster and 170 degree thermostat with his tune. I notice a difference, it does run cooler.

Do you know how much boost you are running?

I've gone from 85, 80, 79 and now on 75/w 93 & torco and about to upgrade fuel system and use a 69mm. Lund tells me with the 69mm and e85 I should be around 15ish psi.

I'm still surprised how well my 85mm pulley runs.... 10.7@128 on average..... I'd like to drop a size or 2 in the future though.... I have run against a 2014 Roush that is running a size smaller pulley and I walk him the entire time. He can get me out of the hole due to his drag radials, but after the 60' I'm out ahead and finish the 1/4 by a car.... We have made multiple passes and it's the same result every time...... We're both auto too....

Sounds like you got a runner. I see you are from Spring Hill. Is that in Tennessee?
