Well I have 215 miles on mine and still only hits 8750 so I guess I have a boost leak?you got hustled...and if you only ran 8700 you most likely have a boost leak...find it and you might find another 10-hp
stutter box with 6 lbs and 1.325's..I bet his exhaust had a funny scent to it...uh like race fuel..
I was born at night..but not last night..

Limited rpm could be a boost leak?
What should the rpm be. I thought it was 8800+/-?

It started out at 8350 for the first 15 miles then 8500 and by the time I had 90 miles on 8750 it might have hit 8800 over rev but 8750 seems to be where it is nowLimited rpm could be a boost leak?

I would check the intake boots as some are not seated properly and it looses some boost. Just something to check. IT can make a big difference.

5-600 ft? Sorry, but I say who cares. Why buy the big dog if your only worrying about running the length of the porch? Where is he at in over 1000 ft? Across the field or Lake my guess is your buddy sucking hind tit. No disrespect, but don't worry about it and wait until break in or when you are going across the lake. Or if you care about the short distance, just clutch it.

He got the bust.I'm not a speed guru but something more seems to be going here. How does a NA Nytro with an exhaust beat both boosted sleds? Especially when nearly all the other posts are how fast the SW is?

Gonna put some miles on tomorrow then try again. I don't want to suck hind tit to a $6000 Nytro with 8700 miles.

Can't remember but is your secondary wrapped 3/3 or 6/1?
8650 is peak hp on a stock sled. Much over that, your loosing hp...
Better figure out how to hook up and get it to transfer, that's why you lost. That and who only runs 6 pounds of boost? You got punked!
Not only this but that race was over before it started. He drilled you out of the hole because he either started before you, or you were sleeping. That and his track didn't spin.Better figure out how to hook up and get it to transfer, that's why you lost. That and who only runs 6 pounds of boost? You got punked!
