My best so far this year was a 10.05 with the new motor and that was with a stumble in the carb at launch. Butch(6t5Belv1) and I headed out to Thompson Raceway Park today, the weather was perfect, early morning air was around 300-400', later in the day when I got a grip on the tune it was much much warmer out but I think it was still great air.
1st pass the only thing I tried was launching off the 2 step to bypass the squirters and the stumble, went
9.93@135.68 MPH with a 1.40 60 ft!
2nd pass I removed the carb/hoodscoop seal pan just because I've never tried it w/o it, plus I slightly short shifted into 2nd, ran 10.000 at 135, 1.42 60 ft.
3rd pass I installed the air bleeds that Monte Smith and Jesse from BIGS suggested(Thanks Jesse for overnighting the bleeds!!!). I'm now at .060 idle, .045 intermediate, and .033 high speed in my 9375 1050 Dominator.
It responded nicely with a 9.900 at 135.68 with my best ever
1.36 60 ft'!!!!
4th pass I dropped the exhaust system which consists of 3.5" pipe and 3.5" PYPES RACE PRO mufflers, no crossover or X-pipe yet.
It went 9.88 at 135.70 but 60' slipped to a 1.39.
5th pass I went from 97 jets to 98's and it went 9.90 at 134.80 with a 1.37 60.
6th pass I went down to 96 jets and boy did it respond with a
9.82 at 136.09 with a 1.36 60 ft'!!! 7th pass I went to 95 jets and it slowed to a 9.86 at 135.69 with a 1.38 60 ft' so I will put the 96 jets back in.
I was thrilled, had a blast today and went home very happy! It really feels like a hot rod now and it will go 9.80's through the exhaust on a true 10.5 tire on pump gas which is all I asked out of this combo. I'm running 93 octane on the street and putting one gallon of 110 Cam2 in the cell on race day for a little added insurance til I creep my way towards straight 93 octane.
The cam is wrong for this combo so winter plans will call for a custom roller and a switch to E85 and possible 9.60's next summer on cheap gas. But if the money isn't there to switch I'm perfectly happy with the way it's running just the way it is........for now.
Oh and I did my first ever wheelie with both wheels up about 3 inches for the first time in my life. LOL!
Next spring we'll play with the weight and do some wheelies, and I'd love to put a transbrake in it.
Here's a video thanks to Butch!
