It's one of the best upgrades for the price. You should notice a decent increase, but don't expect it to add mass amounts of power. I added it with a Diablosport chip so I just noticed them together.

Com'on man, we have been talk about this over and over and over for the last 3yrs. Get over it, I have my UDP since 40k KM and now I am at 130k km. I don't care what theory you have about Harmonic Damp, I just know my car is still running strong(90k km or 54k milages w/ UDP). And I enjoy every single km I drove w/ my UDP.As long as you keep the STOCK Harmonic Damp.(stock bottom pulley)
The rubber is there for a reason use it

I agree, this unit has been on test cars for years now with over 75,000 miles and ZERO issues. We still are running the very first prototype that was made in early 2000 and everything is fine.Com'on man, we have been talk about this over and over and over for the last 3yrs.
