Default How much better is a Torque Convertor than a Centrifugal clutch?

Today the guy at the Kart shop tried to talk me out of my TC plan and into a CC. Realise that it's very difficult to compare apples and apples here but I'd love to hear from anyone who has changed from one to the other on the same kart about performance differences they have noticed. What ballpark increase are we talking in spending the extra cash for the torque convertor? A extra 5%? 10%? 50%?

I'll be running a 6.5 clone over flat-ish ground on an off road course, through rough paddocks mainly. I'm competing against ride on mowers with a lot more power but much worse handling so any power boost for me is vital.

Thanks as always.

I dont know much about them personally, but in case you need info quickly, everyone usually says if you have the money go for the TC. What I do know is that in theory the torque converter is multiple times better if you are requiring a broad range of capabilities. IE, rough off road AND high speed on road. Due to the range of ratios available

I had a cent clutch on my 6.5 and changed to a tc. Made a world of difference offroad (and on hills)
I would really reccomend one if you can afford it. I was almost burning up my clutch. I would say it seemed to act like a 10hp not a 6.5!

Hey Andy, I checked out your racing videos. I think you'd turn faster lap times with a TC because they offer better acceleration and you have to slow down so much for the corners. But if your track had higher speed corners where you didnt have to slow down so much, a high quality centrifugal or disc clutch would be faster.

Thanks guys, I think I'll go ahead and stick with the TC.

I'm up against 125 and 250cc dirtbike powered mowers and while handling is always going to be my strength I still need as much performance as I can get my hands on.

Special thanks to Anderkart for taking the time to check out my races. This year's course should be a bit flatter than last year's but I still think the push from the torque convertor out of each corner is what I want.

Ok now to figure out a new wider axle setup and whether to keep the existing diff or go live.

So much to do in so little time. Good times.

Again I really appreciate the advice.
