Kim did a little math and said that corrected for sea level, it was closer to 625hp. Bret said that he has a very stingy dyno and is usually 50-100hp lower than most dyno's. All I know is that it is one bad dude when you hit the loud pedal. I had no problems turning the cut boggers up in Sturgis and most guys say you need over 750hp to make them work. I did a little calculating and figured I was turning the tires over 100mph in that pit. I came out the big end bouncing off of the rev limiter at 6200 in the high hole, low lock with a 205 T/C. The rears were 35" cut boggers with a 3.50 rear gear. If you have never run a set of cuts, they are bad ass. Twisted Evil

I'd stick with the Boggers, they are a better tire.

How does it sound at idle? Very erratic or is it pretty smooth. Do you have any video of the dyno pulls, I'd love to hear it. I have to pull 18" in my class! Thanks.

Free is always a good reason to try somethin' new... I got a new set of Toyo Slicks for my truck for free a couple years back so I thought I'd run them this year... Wink

Well no documentation on HP numbers here, but we did a little work this summer and upped the power with a cam and intake swap. New headers too. I havn't had a chance to put a vac guage on it, but it should be close to 14" @1000rpm. The cam is Damon's old one. Lemonator Saturday Night Special. Intake is one of the TFS prototype units. Added an MSD dizzy also. I am hoping to hit a dyno this winter with it and get some new numbers to compare to the old ones, but the seat of the pants-O-meter says we added at least 100 hp to it minimum. I can flog the wee out of a set of 38" uncut boggers and it handled a set of 18X39.5 cut boggers quite well up in Sturgis. Very Happy
