Not having studs will change everything IMO on what clutching will work. I have not moved off the stock gearing as we have zero proof racing others that gearing down is actually faster - but most runs are 1000' we've done. Where are you recommending Delrin's be placed in the Secondary?

Brock, will you be doing a pull on a sled with BMP staged components w/o the BMP Pistons?

Tom/Brock, are the SSI Adjustable weights similar to the BMP Goldstars? Where are you recommending Delrin's be placed in the Secondary? The BMP Secondary set-up is identical to what Tom used...you have the choice of 48/44 or 50/44 with the BMP Helix, same spring rate - just and FYI. What...

So, can a person reliably check your TPS with a multimeter? I've seen a couple posts on HCS and Snowest. I'd like to do it, if it can be done without Digital Wrench and have good results? 2015 Pro-S 800 SB

I'm running 1.500" Stud Boy Lake Racers on a 14" wide Hacksaw. It hooks good!

What about 1000' drag races in hardpack snow? Sled is a 2015 Axys SB 800 60th. BMP Pipe/Muffler with Bully Dog. I have BMP Goldstars to use or Dalton adjustables. Primary springs available: 165/310, 140/320, and 160/330. Primary has been to Indy Dan...set for Gates CF Belt. Secondary, I...

Wouldn't the dyno tell us if the engine needs more air when running a pipe, etc?

They updated recent pipes to do just that....

I'm guessing you didn't use any of the reinforcement screen for any purpose?

Photo isn't clear enough to read? What brand and part number?

What's your belt to sheave clearance with the belt your running? .010" to .020"?

I always wondered if it needed more air. But no one is pushing it, maybe other than SLP.

I'll have to try it again. Tried in the past and it seemed the RTV worked better......

Does it dry hard so it become brittle - or still flexible?

What kind of "silicone" are you using to seal up pipe to Y-Pipe?

140/220 works. I'm gonna try a 140/200 with three delrins. But I'm 165ish suited up...

I talked to Indy Dan about this the other day. He said there is no difference between the 2015 to 2016 that he had observed.

Yeah you will, I've seen it on at least 4 of them...

I'll be interested in those results as well!

BMP now recommends their orange primary spring - a 165/310 rate. You could also try a Team blue which is 150/310 so your engagement isn't as high. You'll probably need more magnets to keep rpm down. Heck, I'm around 76grams. What clickers are folks adjusting to keep the nose down, these...
