I will be needing a damper for my 383. Who makes the best one? I have seen a fluid one by March, The ATI Super Damper and some others. I already have a ASP underdrive pully, but want to upgrade if it will be helpful.
The motor will be spending a lot of time at high RPM for autocross events.

Thanks

ATI- dampner

I had ordered an ATI but they were on perpetual back order ...

So, I opted for a March. They look amazingly similar and the March is a little lighter ...

I thought the ATI was a double rubber dampner, not a fluid type???

I believe you are correct.

ATI is elastomer and the March and Fluidamper are fluid filled.

I would use an aluminum shell underdrive ATI. I have a march on my car now and it seems to work OK but how can you really tell - it hasnt broken a timing chain or anything yet The March was heavier then my stock damper but I prefer the one piece fluid damper over the ASP.

And I wanted fluid, not elastomer.

I too am looking at sustained high rpms on a road course.
