I'm building a new motor for my car, I currently have Polyurethane motor mounts. The new motor is going to be a bit beefier and I'd like to step up to solid motor mounts. However when I mentioned it to a friend of mine, he brought up the issue of triggering the knock sensors. I'm going to be running YT Ultralite rockers as well which I know can be a bit noisy... So my question to you all is do you think the solid mounts would cause me any issues?

Thanks guys!

 

good question, i have no idea but i have never seen a thread or someone saying that their solid motor mounts were giving their knock sensors problems

 

I don't think the mounts themselves would either... But my concern is that it's going to be a combination of the solid mounts which will cause more noise/vibration, Yella Terra Ultralite rockers which also cause more noise/vibration, and an aggressive motor. Again I don't THINK I'd have a problem... But I don't wanna shell out a few hundred dollars for solid mounts to get better power/performance, just to have the knock sensors yank timing and ruin everything.

 

It's not any kind of issue at all.

FWIW, it's also hard to tell the difference in-car between polys and solids.

 

Thanks

 

no problems with my solids. they made the car feel tighter.
