Solid engine mounts

[fast924S]

Hey guys, quick question. IS anyone on the forum running solid engine/tranny mounts or driven in a NA that has had them. I have been looking at LindseyRacings solid mounts that also allow some hight adjutablity. I think it would be sweet to drop the engine a little more (inch or so) to lower the center of gravity and I dont mind a little extra noise but if its gonna be crazy annoying then forget it I will stick with my turbo mounts. Thanx

Just wanted to throw in my 2cents.

I would think that if you go with solid mounts for the engine you would NOT want solid mounts for the trans. If you get solid mounts for both ends, what happens when you hit some rough uneven road, and the chassis twists a little while going over bumps? If the engine and trans are both held tight, you'll transfer some of the chassis loads into the torque tube, which i'm pretty sure it wasn't designed for. You might damage something.

Since the torque tube links the engine and transmission together anyway, i doubt you would gain anything with solid trans mounts, but i could be wrong.

If his chassis is stiff enough (read: welded-in cage) there shouldn't be any flex when going over un-even road.

It will be fine with solid mounts. The torque tube is very sturdy, not weak by any means. If it can be used to absorb some of the torsional flex of the body all the better. To do any damage you would have to seriously tweak the motor or trans on the chassis -- like maybe running over a boulder.

From what I've heard (and I admit this is second hand info from other people) if you solid mount an engine you can run into some interesting problems.

As well as a lot of additional vibraton and noise in the cockpit, the vibration through the engine and every thing attached to it can actualy start to undo bolts and nuts even head bolts! To counteract this virtualy every fixing, nut and bolt will need loctite-ing as well as being correctly torqued to start with.

Always wondered why the engine wasn't equipped with shock type vibration dampers instead of balance shafts..

Just an idle thought by a very tired poster...

[nynor]

balance shafts actually minimize the vibration, while vibration dampers just absorb the vibration. thus, with balance shafts, the root problem is minimized, if not eliminated.

[Moneyguy1]

But the balance shaft system adds a number of rotating parts, seals and potential trouble parts. Granted, the damper system is probably not as efficient, but it is passive in nature and not rotating at twice engine speed.

Hey..just wondering...
