The OFE is a very nice clutch.
I've been running my OFE since before last years Thunder in Muncie (June 6-8).
Since then I've put aout 20,000 miles on it.
I dyno'd 457RWHP/950RWTQ. My 1/4 times give me numbers between 480-500RWHP.
I "powershift" at the track, and this clutch holds good. After all night of racing, it starts getting a little weak when shifting from 5-6 but if I BARELY let up on the fuel pedal (during the shift) the clutch holds TIGHT.
It seems to me, the more you slip it, the better it starts holding. Break it in real nice, slip it some but don't smoke it.
Don't be suprised when you take the clutch out for a drive around the block and it doesn't hold the power. Your SBC will slip right out of the box, it takes about 500-1,500 miles to fully seat the clutch.
The only problem I have with my OFE,,, it's not big enough!

I'm wanting to do some more Ponies,, but I don't think the OFE will like me. So I'm just puttin' around with "only" 500RWHP.
I'm waitin' for the clutch to slip, but it's taking FOREVER.
Peter makes some serious clutches.
