Well I've had the smaller pulley in my hands since last season
Been a little too chicken to install it
i've been thinking .. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> install it and lower my rev limiter and shift points and see what kind of boost I'm making right now i'm at 9 psi with the stock one
Then for the track raise the shift point and revs a bit for some more boost and add some race gas. Also looking to get a water injection kit to supress any detonation ..
The truck now launches something hard off the line with the 410's
I'm looking for a low 12 second slip.
Should i do the Pulley swap?

Whatcha waitin on, CHICKEN!! Cluck cluck cluck... I am ordering a smaller pulley for the Whipple monday morning. I think you are thinking along the right lines as far as the rpm's and the water inj. I say go for it.

 

Jim, what rpm's(best guess) will boost kick in with the new pulley?
I van imagine with the stall and 4.10's that thing just leaps outta the hole, specially a lighter 2wd!
