Busa oil system

[Nohair]

Hello- reading on another site and found someone who says that to use the Hayabusa engine in a 7 type car in place of a auto engine would need a dry sump system or a new pan with a swinging pick-up -- has anyone here had experience with the Busa in a 7 and could give me some good info on the oil system thing? I have used bike engines in Dwarf cars with no change to the oil system and they worked great, so I am wondering if the Busa is that different??
thanks for reading

I don't have any personal experience with BEC's, but you can check out Hank's website which has a lot of good info: http://www.hanksmegabusa.com/index.html (http://www.hanksmegabusa.com/index.html)

Looks like a lot of nice Hayabusa parts and info here too: http://www.sbdev.co.uk/Hayabusa/Hayabusa%20Parts%20Catalogue.htm (http://www.sbdev.co.uk/Hayabusa/Hayabusa%20Parts%20Catalogue.htm)

I have heard the same thing about Busa motors needing to be sump'ed. I am not 100% sure if it is due to ground clearance issues or oil issues.

I have a Honda CBR 900 motor in my car and did not have any oil pan mods. I have since added a baffle plate. The guys that race in Class C in 750 Motor Club - RGB say that is all that is needed. I think almost everyone racing Busa motors in 750 MC do have their motors sump'ed.

well it seems that the Busa needs some kind of oil control system if it is used in a drive shaft type of install-- so now I have to ask, does the Kawasaki ZX14 have the same problem? I really want to use a larger/torquer engine if at all possible - I have a Honda1200CBRXX(efi) in a Dwarf car that I am autoX ing now and has no changes to the oil system and it gets run very hard- it is just down on torque/HP to the larger engines
thanks for all the info

My cars sister car has a Kawasaki ZX-9 in it and it is not sump'ed.

FYI it's for sale:

Our Radical has a Busa engine and we do have a swinging oil pick up arm, but it's not dry sumped.

I did tons of research prior to my chosing the R1 for my build,yes its down in power/tq to the larger engines but I intend to add boost after sorting the car this season.
I simply couldn't afford the 'busa/zx14 car kits especially once the $$ to make them survive is included.I can fab all my own stuff to turbo the R1 for peanuts and make well over 200hp with tq to match for less.

Just a thought.

I have a Busa motor in my car and it has a swinging oil pick up. I did it for two reasons.
1). It allowed me to lower the engine, my oil pan is 2" thick.
2). I knew the oiling system would be operating in a non bike mode and without the "well" that the stock unit has to pick up the oil I wanted the pick up to follow the oil.

It is cheap insurance and I am pleasantly surprised to read Feff uses one in his Radical. My car will not corner as fast as his, and that is the bottom line. The more G's you pull the closer you get to needing a dry sump (I believe this is a $2,000.00 expense). If you autocross you may like to consider an Accusump.

Good luck.

If you keep the stock pan with it's vee shape I don't think you will have any trouble. The real advantage of a dry sump is that it allows you to run a nearly flat plate where the pan used to go. Better clearance.
