All I can say is WOW! after my final clutch combo at Revy this weekend.
We have been chasing our tails all winter with the following ramps
414, 415, 417 and 441
Helixes
42, 44/42, 44, 47/44, the stock 43/47 and straight shockwave.
Also 1 mm oversize v.s. stock rollers and all kinds of pin weight combos.
To throw a monkey into the mix we had to deal with clutch alignment issues.
At the end of the season we are finally seeing cool clutches and great track speeds with sustained rpms.
The 2 e-tecs we ran had slightly different combos but the bottom line was that we have been way low in pin weight and too high in helix degrees all along.
Both had 1 mm oversized rollers and the one with the coolest clutch had 414 ramps, solid pins and a Shockwave running approx 42degrees.
This was pulling a 162, 3 inch paddle track and really low gearing.(2.55) This sled also had lots of shim to move the jackshaft over for alignment
The other machine is a stock 154 and had the pins full of set screws, (12+10+6 mm) oversized rollers, 42 degree helix, 415 ramps and a floating secondary. (2.45 gearing) Also a Purple/Pink primary spring for lower engagement.
This second sled had the hardest arm pull but on the short lake both were pretty even as the big track sled with its lower gearing and traction accelerated fast. The short track was about 10 km/hr faster up Super bowl.
Next season we will try to push it even more with 2 mm oversized rollers and try a shockwave helix around 40 degrees.
These sleds need lots of pin weight to stop belt slip in the primary but also need a helix to keep up the rpms. The secondary may be showing some signs of slippage now as they are a little warm but not hot. Still 103km/hr up Super-bowl in fairly tracked snow was great to see. We can still hold our bare hands on the primary or secondary clutches after this pull.
On my 154, I pulled strings on 2 belts in the first 500 kms. After floating the secondary at about 800km's I put one of these belts back on and have been running it for another 1200 km's with no further noticable problems.
Also there is next to nothing for venting on this machine.
Hope this helps.
