Dalton black/orange VS Dalton black/tan

[jonlafon1]

I tried the black tan briefly.

Was running the black orange at 90.
Belt would slip on top end with black orange.

Black tan would shift too quick down low and mid range without changing anything in primary. It was a tug of war contest with the belt. Would not even rpm. This was at 50°.
I put the black tan back on the shelf.
Didn't have time that day to adjust primary to see if I could get it to work.

Currently running the Thunder Products Orange spring set at 60°.

Good info. What helix you using these days?

35 for trail

37/33 helix should not need that much tension even at that tune. I don't run that helix but if i did I would run the black/orange @6/1 and do heat checks on the secondary after a good(WFO) 1/4 mile pull minimum. If its hot go up(twist more) until the temps come down.

Thanks!

What helix and spring combo are you running?

straight 38 from BDX. black/orange dalton V2 @6/3. Heavy hitters weights. Nothing wrong with that 37/33. I think maybe you had to much spring with that black/tan

That you sir.

I've also got an EPI purple and TP orange i could play with as well if either of those are better candidates.

Maybe mike or someone that runs a 37/33 will chime in with what spring they use and what twist. The black/orange has served me very well and other for many miles on tunes/ I think you may just have to test a little bit.. Always start with the lighter tension and work your way up. You will know when you hit "correct twist" your secondary temps should be able to the touch with hands anywhere on sheaves. One other thing would be your offset? Did the belt blow move your stub shaft? Get offset on point and then test ONE spring and start slightly lower and work your way up in twist.

Good advice.

My offset is in spec.

Also have the following helix’s that I can try. 35, 41/37, 35/33

Maybe stick with that 37/33 or the straight 35. Just one change at a time.

I am currently using a 41-37 with the B/O spring at 90.
I know I am running a smaller tune but I have no slippage and clutches are nice and cool.
Any time I ran anything under 35 deg, I would crush the belt in warmer temps.
