dry sump drive system

[kovacs]

I was curious to know what teams have done for drive systems for dry sumps. im sure you run some sort of shaft extended from the crank, but how do you go about attaching this to the crank??

thanks guys

The most common method (in fact the only method I have heard of in fsae) is to use the drive shaft from the water pump to run a gyrotor oil pump. Most teams then use a electric water pump for the cooling circuit but you could accommodate both off the one shaft.

Ditto for us. Arizona has run a system like the one you described above, I think it worked well. Washington ran one too.

At Oregon State we have run a custom drysump off of the trigger wheel connection for four years. We replace the stock trigger wheel with a love joy coupler. The first year the pump was belt driven from this connection, but since then it has used a gear drive instead.

removing the water pump and connecting there negates the need for a gear system (keep it simple). this is how the majority of teams running the CBR600 operate, but it depends on your engine.

That's how we have run it, just be careful you pick the right water pump. Otherwise using the stock water pump drive off of the oil pump works extremely well! Granted you have to machine a mount for it.

hi all

just wondering what oil pumps other teams are using? in 04 we ran with a zzr1100 pump, then went to a wet sump in 05, and i stopped looking into it. but would be curious as to what esle is getting around these days.

cheers

most teams, including ourselves run with the Pace pump (http://www.paceproducts.co.uk). though it is expensive. ive toyed with the idea of trying to mate two standard gerroters from a cbr600 together in a custom housing, as ive seen a couple of teams do with other engines. anyone tried this?
