2.3L whipple pulley coyote

[Davidx9x]

Anyone know what would be the smallest pulley on a 2.3l whipple blower the stock 5.0 engine can take? (93octane tune) also what would be the biggest cai to go with the pulley?

I would say 3.25. That is what I ran when stock. With my longtubes and off road x I saw 9.5lbs. I believe the JLT is the biggest you can get for Cai.

Awesome, thanks! Which tune did you run? And how big was the JLT?

I ran a Lund tune that was done on a dyno and back up with street logs and it just never ever ran right. I gave the car to JPC for two days and it's been flawless ever since. Not sure on the JLT I'd have to look it up.

Great info! Thank you.

Digging this thread up from the dead but I ran a 3.125" all last summer and will be trying a 3.0 this spring...

Also Lund tuned on 93, I don't see any knock or timing being pulled
