Seems like some comp between March & ASP, lol. Glad to see that everyone thinks its a good buy....it seemed to be a cheap way to add a little extra get-up. Thanks for everyone's advice.
Harmonic Dampers Hey guys what's up. There one thing that I haven't seen anyone discuss is that almost every Cup engine uses ATI and they spin to 9k. In a fluid dampener you have a weight floating in silicone fluid , so what happens when you leave the starting line then shift @ 7k and your rpm's drop.That weight isn't going to immediately match the current rpm's. I believe the fluid damper are good and work very well @ lower rpm's but if you like rev's (like me) I don't think the ATI can be beat. They're available in steel and aluminum and they're adjustable and rebuildable. All you have to do is change the o rings whether you need harder , softer , or just new. And for the best part $$$$$$ anywhere from $400 - $500. You get what you pay for . I would like to see a dyno , track , and engine teardown comparison of these damper , but I always ask for a lot .
