How about from Whipple themselves, geez that was an easy one..... :rollseyes

I want a 3.25..... That along with my 2lb lower will give me 17psi

LOL, had the Whipple on for a day and you already need more boost!?!?!

lol.... :lol1: Yeah I got a custom dyno tune set-up for Tuesday Morning so I might as well go ahead and make sure I will be at 550 to 575 rwhp....

Do you think I will be at 550 or so with just 15 psi??? If so I'm not worried about it..

I made 554 STD (abt 540 SAE) @ 13 psi. You should have no problem making 550 w/ 15 psi. Its up to you but i'd get the smaller pulley. You should make 590 - 600 sae with the 3.25 upper and 2 lb lower. Depending on your other mods, maybe more, maybe less.

Go with the RR Non slip....it builds boost faster that the stock style whipple pulley....Amazon is a direct dealer for RR products.

I have a 3.25" I can sell you... PM me for more info...

And how does it build boost faster than a pulley from whipple direct ? :shrug:

Definately - and then some. I made 560ish at 15lbs - still have the factory h pipe too!

I PM'd xtremejc for the 3.25, but all I really want know is 550 to 590 rwhp and tq to be 550 or so..

PM'ed you back !!!

it is an patented ultra gripping pulley with features designed for minimal belt slip..we have dyno tuned many Whipple cars and the ones with the RR pulleys build boost faster than a pulley with no RR features.

So it doesn't build boost faster, But allows less belt slip.
So lets just say that the RR design in which RR and Billetflow pulleys use increases the drive performance.
But if belt slip wasn't an issue or you switched to the new BILLETFLOW IDLER BRACKET which gives you even more belt rap the performance of two different manufactured pulleys of the same size. There would be no difference in which the level of boost is obtained.

Belt slip is what we are talking about in this case.
Thank god for people like RR and BILLETFLOW which adress this problem and have a working pulley system to combat belt slip.
