Engine balanced?

Hi guys, im working no putting a 95 750 motor in my 71' honda n600. Im working on mounting the engine and im trying to find out if it can be mounted directly to my subframe or will i need rubber mounts.

More details on the car.

They are bolted up. no rubber mounts that I know of, might be good to add those type of nyrod bushings thats used in a lot of rear suspension in cars for that added dampening.

 

Dear Colhogen; I think we have two different terminologies going on here all
at once. Engine balancing is a term meaning how all of the recriprocating
components have been and to what extent been balanced ie,pistons,rods crankshaft. Usually a racing engines internals are balanced differently than a street engine. I think what you are asking is how much vibration is within a particular engine and to what extent you need to dampen it. At least I think that is what you are trying to accomplish. eddie

 

This is an absolutely awesome project!!! I want you to keep this board appraised of your progress on this!!!

I think the VFR gauges in the dash are the tits!

The VFR motor is not particularly buzzy, so I think that you could get away with mounting it solidly to your frame. However, it may be a little buzzier if mounted solidly in a car frame. I would try to fab up some mounts using urethane bushings. I have heard that the rear trailing arm link bushings to a '92-'95 Civic/'94-'01 Integra are excellent to trim down and use as solid engine mount bushings...

Either tht or some hockey pucks...:biggrin:

 

How will you be connecting the tranny output shaft to the MG rearend? It's going to need some rubber damping to keep the teeth on the tranny gears.

 

Well i went ahead and made solid mounts. If its too bad i can always redesign them.

as far as driveshafts go, legdends cars and other bike powerd cars use a adapter in place of the gear and the driveshaft is splined so it can move freely.

 

What I've seen at the track is when the output shaft is rigidly connected to the rear wheel like that (no rubber dampers), the shock from hard up and down shifts can shock the transmission gears. I don't know how often the legends guys have to get into their trannys.
