Hay guys, wondering if anyone can help, it’s a btt off topic I’m afraid.

I am starting a busa conversion on my megablde, and just wandered to assess the current thinking with regards to dry sumpping the engine. I get lots of people telling me I will need to, but when I ask them who they know who has had an engine blow, they cant answer, and I get the impression they are just perpetuating what they hear on the internet.

Any direct wisdom on this subject would be great Thanks (any good links to info too would be cool)
This will be a road/track car (it will be run on slicks)

Thanks guys

The wisdom with the 'busa engine, certainly from a Radical perspective is that it's best not to. Just make sure you keep the oil topped up to the correct level at all times.

i think radical are probarly right there appears to be more engine failures attributed to the dry sump system

What preparation should I take for the engine then, if it is left wet

A baffled sump? Anyone know where to get one

I'd advise having a chat with the folks at Powertec (the engine division of Radical) as they'll know exactly what to do (and will, of course, be able to supply the necessary bits).

The engine would presumably be mounted longitudinally in the Megablade rather than transversely in the Radical though? But it will see less overall force, so presumably if you can get away with it in a Radical at all it should be fine with a baffled sump?

From what i've deduced... all problems associated with bike engines blowing up due to oil surge are when the engines are mounted along the length of the car. when the engines are mounted transversly (sp?) (as in the radical and the donor motorcycle) the engines are not subjected to the same oil surge under acceleration and braking.

My opinion dry sump when not tranversly mounted... there's always the baffled sump option though but thats another discussion

A bike doesn't see any lateral G though (due to leaning), whereas a Radical will see over 2 - so I imagine baffling is critical!

Have run both dry and wet sump on 1300cc busa, Dry sump is definately more reliable. In wet sump the oil level is super critical.
The dry sump sytem produced by powertec is problem free in my experience.
