Anyone run 3.25 or smaller on a whipple

[HRSEPLA]

I just tried, but the 3.0 6 rib Griptec was out of stock...
I’m ordering the Whipple 10 rib kit tomorrow morning instead!
Someone else will have to be the 6 rib guinea pig this time! Lol

No fear here! Proper installation is key! I think...
All good so far

Fear of it? I haven’t researched it yet, what am I missing?

Fear of snapping the crank (snout)

I just read all 16 pages, whew. The common denominator 'seems' to be installation related issues?

I believe that’s it exactly. There’s a lot of fast cars running it with no issues

May be but it also seems it’s more common with the ATI damper .

Proper installation includes measuring and honing fro proper fitment. These are not made to pull on to the crank without measurements and honing done. Some get away without doing so and some don't.

Changed my mind again.. lol
I have a new 2.85" Griptec pulley coming for the Gen 5 and will give that a shot! I was happy with the 3.25" Griptec performance and with Jon Lund's awesome help on the timing ramp and tuneup, will give it a GO!
Who's joining me! lol

I'm totally interested in the 2.85" pulley results. I'm running a 3.125" 6-rib and want MORE BOOST. Where you sourcing the pulley from?

Straight from Griptec

Straight from Griptec

I thought the sizes decreased (or increased ) by .125 ?
I would thought the next size/ down from 3.0 would have been 2.875 then a 2.75 .

 

[HRSEPLA]

Griptec said 2.850 was it

 

[olaosunt]

How much boost are you expecting .

I think the 3.25 is ~ 15-16 psi .
19 psi ?
