Thunder Products (Big Venom Viper kit) with Heavy Hitters

[NOS-PRO]

His new website looks great!

I have to personally thank Lonn at Thunder Products for a great year racing and a much better year trail riding coming up

Just ordered my big venom kit.
This is my first time tinkering with clutch work.
I hope this kit does the trick to this sleepy sled.
Lonn was great and explained exactly what this kit should do.
If it works like it's supposed to I will be very pleased.

Excuse my ignorance in clutching but Was just thinking....
If I'm not mistaken the COTC uses a GWG spring in the primary and original secondary spring ???
The thunder kit uses the original primary spring but uses a different secondary spring.
If this is correct what's the difference and how does it effect the clutching.
Also I'm wondering if there would be a benefit to using a different primary spring with the thunder kit.

I'm sure this was concidered with the thunder kit as they obviously know what they're doing.
I'm just asking for the education part of it as I have limited knowledge of clutching.
Thanks

No easy answer here. Clutching is a science. Spring rates, fly weights, and helix angle all affect how clutches work. They control shift and rpm to move the sled. The goal is to do it as efficiently as possible to achieve the best results. Changing one component effects the others. Many miles of testing were done to produce this kit and make it great. I suggest you don't change components as the result might be undesirable. It's hard to explain 30+ years of clutching in one paragraph. If you really want to learn clutching read this book at least twice. Olav Aaen's clutch tuning handbook. It's a good start to try and understand what going on. It's not easy to explain and olav does a great job. I hope this helps. Pm me if you need more help.

Thanks for the reply.
I guess it's just different means to the same end.
Everyone is looking for the best possible performance from their sled and I guess through clutching there are many different ways to achieve a certain goal.
Sorry for what may be a vague and difficult question to answer but I like to have some understanding of what I'm doing when I change things with my sled. Especially such a major component as the clutching.
I assure u I was not imply that I would be changing any components to my big venom kit when I receive it. It will be installed and that's it. I am certainly not qualified to make modifications to something I know very little about.

Just wanting to learn!!!

And I will read that book...lol!!
Thanks.

LOl. I was not trying to avoid your question but there were to many variables for specific answers. Once setup if you have any specific questions please ask. I am more than happy to help.

Like Shagman mentioned, clutching can be a real pain in the butt and really hard to understand from a blindsided point of view. We were all at that point one time or another.

Basically the other kits that use different springs for the primary need the heavier or lighter spring for the weights to keep engagement down, to raise engagement...but then the weights need to shift the clutch correctly or you will either bog or rev too high.

Thunder Products kit, we tried to keep it as simple as possible and with Lonn's advice, use a custom made spring for the secondary that will twist pretty much the same as the stock, but prevent coil bind. The original primary spring works great and gives you a very low (as low as 2,550) engagement which allows you to just idle up to the gas pump, next to your buddy's on the trail. Also, it doesn't give you that unexpected jerk when trying to take off.

As Shag mentioned, we are both here to help

I think the key here is that any of these clutch setups will get you very close using their own combination of weights/springs, etc. With any of the common clutch setups you have the option of running the prescribed recipe OR you can adjust to fine tune to your liking and your sled's performance with moveable weight, shims, etc. One thing that I will add is that with the commercially available kits you have the benefit of countless hours R&D tinkering and testing in a wide variety of conditions. Depending on the kit you have the ability to fine tune the weights without clutch removal in a matter of a couple of minutes in some cases.

P.S. The COTC flavor of the month has gone to the BOP soft start primary spring which I believe has the same or similar start rate as the stock spring which in my opinion is a good thing.

Thanks guys for the education!!!
I can't wait for the kit to arrive and start tinkering with it.
At least there's a good technical support team here on standby..lol
Thanks

My Viper starts off at 2600 to 2800 RPM on the soft touch spring, couldn't be happier

My clutch kit arrived a gates belt the 911 cover and OSP secondary adjuster is here. Now if this job thing would go away I could do something.
