Anyone running Whipple Gen 5 on 3.75 pulley?

[Stang78]

Anyone out there running running the 3.75 pulley on their Whipple Gen 5? I'm just curious to see what times you are getting with your combo in what DA?

I haven't ran this combo in the 1/4th yet. My best 1/8th with this combo is 6.7 @109.4. It's consistent 6.7's. Just trying to see if I'm in the ball park of what others are getting? This was in 2900 DA and 1000ft elevation. I've got to get my 60ft down. I'm cutting the same 60ft as some NA cars.

I'd like to see what others are running based on their combos? Car made 820hp/691tq at 7200rpms in 6th gear.

Seems about right .

Slips below of my first 2 passes this season in my 18/Gen 5 whipple /PBD tuned/ 3.625 pulley /E85/stock exhaust and cats/3.55 rear end / full weight PP1/premium with magneride .
Made about same power as you did in 7th gear but less torque .

Faster slip with big and littles same day
DA was about 400

Thanks! What rpm are you launching the car at? Your 60’s are way better. Are you on stock suspension?

About 1500 rpm launch .

Magneride but lowered with eibach springs (more for looks but may be hurting the launch )

I had a 3.55 rear end then but since switched to 3.31’s
I would have done 3.15’s but I already had the 3.31 assembly and its iron so should be stronger .

Looks like my clutches may now be toast since we got rid of most of the torque management

Waiting for ship to instal the McLeod steels/clutches.
