I would PM NOS-PRO, I have the TP kit on my turbo viper and it is awesome! It is set up with there orange primary and orange secondary spring. I'm around 3200-3300 at engagement and can creep around just fine(I had to do some fuel tuning to the power commander to actually get it so it wouldn't jump around so much on engagement- way too lean). but I would get there opinion on tuning before saying anything else because for me anyways this kit works very well.That would be appreciated

My engine changes speed too quickly at engagement to give RPM number. I’ll say that I ran BSB with two glide washers, the WPW with two washers is lower and smoother. It doesn’t slap the belt as much as the BSB. It makes it easer unloading/loading sleds and creeping up to road crossings/gas pumps. No blipping the throttle any more.I was looking at that spring, what are you seeing for engagement speed? Mine with the TPvenom / 2 glide washers and stock BSB is around 3100. Also thinking that it should shift out just a tiny bit quicker down low which should help with mine still tapping the limiter a bit out of the hole.

Thanks for the replies. I went with the Schmidt Bro's kit and driving it around the yard it is super smooth. Can creep as slow as you want and not jumpy. Perfect for what I was looking for!

Snowdust can you tell me which Schmidt kit you went with and what you are seeing for an engagement rpm? Did you stick with the BOP primary spring?Thanks for the replies.

It is their comfort clutch kit. I just did the basic which is a primary spring and new rollers. Didn't check engagement but it says 2800 I think and I'm sure that is about right. It'll be great to keep it engaged more in the corners as well.

I'm sure Ulmers setup is great as well! I have ran his stuff in the past with great luck.
