curious: how much solid tranny and motors mounts vibrate?

88rxn/a · 03-21-2008, 11:00 PM

i have these installed in my car and i only got to drive for 1 block (moved to new house) before it snowed and i really got a chance to do anything to the car. this was after i did a total tear down to the chassis and painted and rebuilt the car. some of you may seen this on the "evil forum" as my build up thread. but when i drove the car it almost sounded like a grind in the tranny? it didnt grind before the tear down and i might have mislead the noise for vibration since when i did give the car some gas it made a decent amount of vibration. i was hesitant(sp?) about my clutch install and thought i messed it up by installing it backwards and couldnt get the car to move or go in gear. it turned out to be the clutch pedal needed adjusted. fixed that. now i need to know if indeed these make your car vibrate enough to cause noises you wouldnt expect?

BTW:
a 4 inch DP, 3 inch test pipe (hollowed cat) and 3 inch exhaust didnt help matter either!

I run solid diff and motor mounts, you get some good vibration within' the 1500-2000 range, and running a kaaz diff with the mounts gives me a good chatter feeling.

its not as bad as you'd think.

I find the largest benfit is the help it gives on keeping the tranny in place during hard launches. It was alot easier to miss a 1 - 2 shift with stock mounts since the tranny was getting twistsed out of position with them.

Vibration's not that bad though.

maybe the fluid is either to much or not enough. once i get it going again i can find out if in fact its just an OLD car vibrating or the tranny. thanks for the input.

Hmm, does it make the sound with the tranny in neutral and the car idling? or with the clutch engaged in any gear with the car idling?

Or is it only while driving in gear you can hear it?

A couple of tests to do would be (presuming its makign it while driving) to get it going down the road and making the noise, then pull it out of gear and see if it goes away, or push in the clutch and see if it goes away. That will narrow down the possibilities.

But yeah, check the fluids as well.

pretty sure yeah,
i may just put it on jacks securely and have someone put it in gear and get it going so i can listen and check to see what it was.
