Lock-up clutches

[gsbill]

We ran the mtc lockup on our nitrous bike. Only to help with clutch feel and to keep the clutch from slipping with a sticky race tire. Our bike made about 250hp. I rode it on the street too. More than likely you dont need a lock up on the street. You will never get the traction to get any benefit from it. You will spin and smoke the rear tire first.

Hi lecroy,

I am sorry if I wrote something to make you feel this way.

No, you didn't do anything wrong! Only thing I meant to say is that I only drive my bike on the streets and don't race it. This way things are much less critical than in your application and therefore I was surprised to find interest.

Anyway, you wanted to know the width of the MTC spacer: 33mm.

It's a good quality cast that lends itself to be fitted with a coupler for the return-oil from the turbo.

Marco.

I have been looking for a low cost solution for a data logger for a while now and had started to make an open source unit. Now I think I may have a better idea. The model airplane guys also use data loggers and there is a company in the USA that happens to make one that appears to be a very good. Check out their website:

They offer a few different units, all at a fraction of the cost of what the lowest cost logger I could find. They are also very light weight. All of their units have two 16-bit RPM inputs. This is just what you would need to do the clutch measurements I was showing. They can also measure EGT, pressure and a host of other things. The analog inputs are 12-bit for the low cost systems, which is more than enough for most applications. And again, they are very low cost! I'm talking $150. I am not sure I could sell my kit for this much.



I spoke with them about using their products for motorcycle drag racing and it sounds like they would be interested in supporting it. They would be willing to make changes to their software and hardware to fit our needs. The only question is if there is enough interest.


Please take the time to contact them expressing any interest you may have.
