k thksThunder doesn't reveal his rates... But I can tell you it's one the most stout springs I've handled

I put this spring in this weekend and wrapped it at 60. My hands still hurt!! Made my stock sled much more responsive with the stock 35degree helix. I was also wondering how different brand helixes measure out compared to the stock helix. Turk had a post years ago comparing different helixes (he measured them)and they were off by a couple of degrees compared to the stock helix. For example a Bender or Dalton may say 35 but they act much steeper or shallower than the stock helix. I miss Turks clutching posts. He helped me a lot with my RX1, APEX and Nytro.Thunder doesn't reveal his rates... But I can tell you it's one the most stout springs I've handled
I knew it wouldn't take long for Mr dalton to chime in. I'm not singling out anyone's brand just pointing out the fact that they're not all same. Testing is a must.
what torsion you have to be? 6-2?Ulmers spring next to TPs spring. View attachment 134645
9-1, ulmer says its equivalent to stock spring at 3-3 when you compare with a fish scale.what torsion you have to be? 6-2?
make sense and look like have more compression and no coil bind.9-1, ulmer says its equivalent to stock spring at 3-3 when you compare with a fish scale.
I also found the same results as you back in the day with 835 SRX running HeelX roller secondary 41/32 stiff spring, motor had plenty of grunt to accelerate and top end was amazingNo details needed, shallower angles have always work better 4 me. If you remember the old days back on the TY two stroke forums Turk or Srx Majic had tested some roller clutches. The conclusion was after 1:1 shift the clutches become very inefficient and belt tension drops off significantly. Best top speed was achieved with a 32 degree straight helix and heavy secondary spring. So I started testing the theory also and found I could get 5~6 mph more on a shallow helix and stiff spring. I had my SRX over 120 on Radar bone stock motor, killing ZRT 800’s on a wide open lake only clutching. Yea they accelerated faster but with some room I always reeled them in. Even button clutches gain a bit below 40 degrees. I believe I was running a 42/32 helix on a Haulk roller silver secondary spring.
Maybe this heavy orange secondary spring from TP is doing the trick and keeping the belt tighter?? Just my experience with helix angles is all I’m trying to convey.
I bought the same set up, waiting to give it a tryI ordered and installed the big venom kit along with the 33/35 helix and orange secondary spring based on you and Shagmans reports. Thank you for all your hard work. I'm sure I will be very pleased with the results.
