I tilted mine up about that far to get the 'V' angle close to level so I could make the exhaust work.
Packaging wise, with the motor sideways in the car- it's kinda screwy anyways, since bike engines never have side loads.
The sump on the 800 is pretty square, and the pickup is right in the middle, so it really should get a FSAE-style sump/pickup extension. But the motor's so darn tall already it would be a pain. That's why I put a pressure gauge in place of the idiot light, so I'll at least be able to observe if it holds pressure under acceleration. The few 1st/2nd gear blasts I've done with it so far look promising.
Right now at the angle it's at (tilted back so the driveshaft has a straight run to the reverse box) and rotated to make the cylinders level leave it about 3/4 of a quart more than stock to fill the sight glass.
I see Anton you've had to overcome the same problem in virtually the same application... Did you fab/install a baffle into the pan?- I plan to do this no matter how I end up tilting/angling the motor- I'm so freaked out about oil startvation it may just be to make me feel better than anyting else.. Also, as I read your post, you tilted your motor in both directions as I'd like to do mine, and having done that requires that you now add an additional 3/4 of a quart of oil to get up to the marks on the sight glass?-- If so, I see this as a benefit; more oil= more cooling (these engines run notoriously hot in the bike-maybe an air flow issue?).. also, more oil would furthur submerge the sump- another gain methinks- if only by a few mm...
I haven't done anything to the sump yet, as a street car I think it'll be ok with the extra oil that's in it -> yes, the tilt gives some extra capacity... The pan is baffled a bit in the left/right orientation in the car:
The thing to worry about is having the oil level high enough that the trans froths the oil around, raising temps and overworking the stock air/oil separator. I think the raised level is pretty much a wash, since the pickup is forward of the sight glass
I've been able to keep the engine around 185-190* with extra radiator and a Swift thermostat to replace the famously 'fail open' Honda thermostat.
I think it'll work, but I'll let you know more shortly, once I get the Yahshuatwo reverse box. I still have a pile of DMV paperwork to wade through as well, but moving permits here I come!
