the weight of the pulley is where your increase will be, and the might have a gain of up to 5 hp.. might. usually you see a gain of 5-7 hp on a light weight pulley for an engine in the 200-250 hp range. but different engine design only drop different amounts of weight safely. since the pulley is not undersized you will still have the same drag from your accessories. this is where most pulleys claim to increases of 10-15 hp,because there is less drag. the real benefit of this pulley is less mass will help you gain rpms faster. a light weight pulley with a light weight flywheel and high performance clutch will run through the rpm's much faster than stock, getting you into the power band faster for better throttle response.
speaking of which i am interested. will this fit the new engine? and why such a long lead time?

You forgot that you can increase your MPG as well because your engine does not have to work as hard. Pulleys have been in and out of production for a few years, just nothing staple because of lack of demand (or at least people actually buying).
Re: JBP Crankshaft Pulley
sorry,i forgot that. i dont mod to increase mpg. i mod to go faster. :lol:
Re: JBP Crankshaft Pulley
Thanks Dan. Yea, we did a small production attempt with Daniel's UDP, but it never hit off and now it's sitting here. JBP is willing to produce it in mass if it is desired (and paid for).
With Daniel's, we saw an immediate increase of I believe 4hp on his Automatic Aveo with The Goat Intake, Ported Exhaust Manifold, Custom Exhaust w/ Magnaflow Muffler, and NGK Plugs/Wires. Before was 86fwhp, after was 90-91fwhp.
Tuned and with a 5spd and lightweight drivetrain it can make a difference.
Re: JBP Crankshaft Pulley
I'm interested, but our excess cash got absorbed into a family emergency. So, I will watch this thread until thins go through.
I'm possibly into this.

was the dyno before and after only the pulley? or was all that stuff put on for 4 hp?

Just the pulley
