is there a rwhp difference or acceleration power difference between a car using stock mounts, polyurethane mounts, and steel mounts, if so how big a difference between each??
anyone? I need new motor mounts and I wanna be certain about this one thing first...even tho I am pretty sure I wont do solid mounts...the NVH would be pretty bad as I hear
They are just motor mounts man, stop stressing. Stock is stock....poly would be the better choice, and solid will give you a massage everytime you drive if you have a cam. I say go with some poly's
You arent going to get any hp change from your mounts. I use the polys on my 347, cause solid let you feel every vibration and they have plenty of strength. I have heard cobra mounts are stronger than stock but cheaper than polys...but have never looked into it.
