You have to remember your sled is a supercharged Sled ours are Turbos they require different set ups. Your sled delivers power instantly while mine takes a second or 2 to spool to full boost. I've had both and even suspension set up is different for both. We launch between 3400-3800 rpm

now that is interesting. lower launch rpm, thats a start.
track hookup is okay. at least for now, the only thing spinning is the belt.

today, went back to napi..
Worked on clutching... got her to grab that yamha belt for good now! but started having traction problems...
then solved traction problem...
and I am now right a 1.30 60ft time
Was running out of gear and engine rpm by end of track a 156mph.
My last run was a 8.56 (or 8.58??? nor sure) @ 156mph and sled started spinning track a little after the 60ft mark... (did not make a good burnout on that one... my fault)..
anyway, I have now figured out how to lower those ET on that pig heavy sled

Good to hear. Did you change your engagement and if so to what rpm?

3900-4000 rpm is the engagement now.
learner how to tune the 4 secundary arms on the rageVIII clutch... (which I never really did before) and some judicious tuning adjustments
Now I would need to get rid of some pig on this sled...
stock yamaha steel suspension brakets which weight a ton, exhaust weight a ton, seat too...
Is there an easy way to install a small gaz tank in the stock tank? because I always run 5 gallons or so or gas in there to avoid fuel problems... that is 30 easy pounds right there too.
Anybody have weight reduction ideas for me?
sled is weighting with 5 gal of gaz around 720# right now. would like to get it down around 620-630.. but don't want to sacrifice the appearance too.
Low 8's with same power might be possible if that weight goal is attained.

My last run of the day:
http://www.youtube.com/watch?v=KK06wESC ... e=youtu.be
still a little bit too much loaded on the start.. but I dont think there is much more to get out of such an heavy sled on the 60ft... maybe 1.25-1.26... ???
How much hp does a supercharged sled makes at 23 psi boost and 11500 rpm typically?
I only dynoed this sled at 28 psi of boost... and it was 380hp at 10800 rpm...
