+1. Just be like me and start building a shortblock on the side. I've only got 1200 into mine so far and the only thing i need still is bearings and to get it balanced, and will be good to 900hp.

Yea, I really need to.


I got that edelbrock manifold which im not even sure if it will make the car any faster at the track but we shall see.

Im swapping to an 8 rib pulley setup so hopefully it will make full boost all the time cause it showed 13 psi on the dyno and I barely hit 10-11 on the street so I know im getting belt slip.

Also, the crank pulley is 7 inches vs stock 6 7/8. aka .125

Is that the same as dropping from a 3.125 to a 3.0 supercharger pulley? Anyone know?

I'm not sure about the pulley sizes, you'd think they'd be the same thing, but there may be a difference between the s/c pulley which gets driven, and the crank pulley that drives.

also i'm sure you'll pick up a few ponies up top with that intake. a lot of people talk down on it if you're putting it on a stock block because you cant rev it high enough, but i heard from many that you pick up power from 4k plus so it should still work well.

Yea, honestly, its probably not a good intake on the stock bottom end.

It really didnt start making more power till about 4500 rpms but it definitely does out perform the PI a good bit from 4500-6500 rpms.

Just depends how high you want to rev it.

I would say I gained a solid 30 rwhp up top, being modest. Gains could easily be 40-60 rwhp at some points, especially if you compare PI vs this one at like 61-6400 rpms

It may work off a percentage so that .125 on the crank pulley isnt the same as .125 on the blower pulley since the crank pulley is twice the diameter

justinschmidt1

Baseline impellar speed is 54120 at 6k now

3.125 to 3.0 pulley would be 56375
with same pulley and crank pulley up .125 to 7 inches only takes rpms to 54670


so the crank pulley is less effective

I too recommend getting to the tens via suspension and weight, rather than more horsepower, for the sake of your engine's longevity.
