Motor mounts

[hensleyt]

At what ET is poly mounts needed ?
I have had a pass or two with KR I believe it to be false it happened at 2-3 shift straight up straight down to fast for me to see it on scanmaster showed up on logger.
Mount are new stock type (all three) I cant see the head pipe touching or any thing else
Thanks

Don't know what my new build will run but got a good deal on H&R's so we threw them in. Nice way of getting rid of the torque strap and like to feel the engine a little more in my seat. Shooting for 11's myself (but didnt build with a number in mind.)

There always a good idea but i dont believe theres a magic number for when they are needed, when i pulled my engine to build it i went ahead and went with both HR poly mounts just to be on the safe side.

I wanted to be safe and 11.5 did not seem like it was asking too much out of a good new stock set .
this KR I get is not every pass ,I think its false ? a mount is a lot cheaper than a engine
So have you done all three mounts , just the front two ,or just the drivers side

its not, healthy stock mounts and a good t strap should be fine,there are lots of things that can cause kr.
