That’s nasty. I would expect that to be high 9s at the track. You should be cutting 1.3-1.5 60s.
Honestly if expect low 9’s with this pulley. If it goes slower than 9.50’s I’ll be very surprised. It all will rest on the 60’ though. It has 325/50’s though so hooking shouldn’t be an issue

I was talking about N/A. With the blower high 8s with traction shouldn’t be a to hard to accomplish. All about getting the weight down in those cars.

Holy Holy Holy! This thing is going to FLY!!!

A 4.38 pulley in this light of a car...will be a monster. Its going to come down to the trans tune, cause I have seen 1 second gain with just trans tuning, and no change in blower pulley. THAT is where the gains are.


I have a Gen2 Coyote Coupe with a P1X almost finished! You are motivating me!

That’s what I like to hear. Yea Lund has the 10R80 trans tuning down, so as long as I can make the 325/50’s hook she should move out pretty well. Any idea what kind of boost/power the 4.38 is good for on E85? I have Longtubes and full 3” exhaust with ID1050x’s. Got it running last night just working on cooling system and catch can now.

On a p1x with a4.38 pulley 7-8 pounds maybe less.

On a 18+? Are you sure? Guy above said his 4.25 made 13...

4.75" @7400 rpm = 8.5psi

I would say with some good RPM you will make at least 13+ psi
And I can say that a P-1X on 15.5 psi on 110 octane will make 937 rwhp in SAE (DynoJet) and that wasn't even me leaning on it. That was literally the stock procharger tune, with good gas and a little more boost.

Your car will flat out FLY FLY. I can't wait to see it

So I need to step down to a 4.75 is what you’re saying Lolol great results, I’ll be on E85 so should be pretty wild. I got plugs and coolant system done last night late, so going to take a first drive tonight if I get off work early enough. Otherwise be tomorrow, y’all wish me luck!!
