I scheduled my car for the dyno this Wednesday. At partial to WOT, the driver side pipe bangs on the floorboard. I have poly motor mounts on the way. Will this banging have a negative affect on my numbers. I have read that the banging will set off knock sensors or something to that nature. I just want to make sure that this won't cause me lower or inaccurate numbers. If that is the case, I will wait until I get the poly motor mounts in. Thanks for any input.

 

it will probably cause some KR, mine did. i had to put some rubber inbetween so it wouldnt hit

 

I ended up using a five pound hammer to take care mine hitting the floor. I also had to use some rubber hose, just in case. My problem was with TSP TDs.

 

Exactly, it could cause some knock, hp loses less than 10. Or you could be fine.

 

So should I wait until the poly motor mounts are in, or go ahead and dyno as is?

 

lay the rubber in there then dyno. couldnt hurt. That is what I did when I had my y-pipe.

 

Thanks for the input, but I decided to delay the dyno until I get the poly motor mounts in there. Hopefully next week or the week after.
