Racing clutch

[Jrdragbike]

Hey guys how much of a diffrence does a clutch make I got 200 to spend and I'm a bigger guy and I want to be able to launch hard and still have my top speed I want to run bigger than a 13 t gear,
I wanted to buy a torque converter but I don't think my bike will have as much top speed as it did or is there a spring combo that works for the race for top speed,
My mods are
Billet rod +10
Flat top piston
Black mamba cam
Billet flywheel 37lb springs
1.1 ratio champion rockers
22 mm mikuni

Find a rebuilt bully clutch. They are well within your price range. I had a cheetah clutch and had problems with it locking up. It wouldn't disengage when I let off the throttle. I race karts and have used many clutches. Bully clutches are one of the best.

Truth be told I have a new bully turbo to try out atm

maybe its just me but 37lb springs sounds a little excessive.

yes but he is running stainless valves which are heavier and larger valves, it is recommended that you use 26lb springs as far as I can remember, but that all depend on your installed height too and type of rockers etc.

Heavier springs are needed for high revs with larger valves to avoid valve float.

The mamba cams come with springs. In my opinion if you don't have valve float you don't need monster springs. You end up wasting horsepower overcoming your spring pressure.

The CHEETAH is junk . We had it on the super powell with the NR racing limited mod honda and it would lock up and was very hard to tune if not impossible .
Look at the Hillard shoe clutches , i have the FLAME on my rupp and love it you can change springs in about 2 minutes and its the smoothest clutch i have tried .

Or you can try the BLAZE model , cost a little more but is more tunable for RPM's . We run this on the super powell which is a heavy bike and makes big power . Its set at 2700 and has a 11 to 1 gear and jumps off the line and pulls to 9 k with no problem .

With either of these we have seen little to no slippage or any sign of lock up .:thumbsup:

I have a lot more lift and much bigger valves then what your running. You don't need anything more then 26# springs, your actually taking power away trying to compress those springs.

and not to mention more pressure which equals wiping the cam

Ok I'm gonna switch back to the 26s I did feel a diffrence in the 37s it got less torque

I thought this was a clutch thread :shrug:.

With your hillard clutches which launches the best the flame or blaze

 

[David wulf]

You know I can't tell a difference in the two . I know you have more options on rpm engagement with the blaze .

Is there a way to have decent speed with a tav I want to have a 15th gear on the tav and 60th on the rear sprocket

 

[David wulf]

I really don't know much about TAV s with high rpm motors . The VW guy I think does and could help you with a TAV
