We now have our 25% underdrive pullies in stock and ready to ship. These pullies were good for 11rwhp on a stock SRT8 and 14rwhp on our 426 300. They are SFI approved as a harmonic balancer. This is not just a pulley that could vibrate and destroy your engine, it is an actual balancer as well.

Cost is $249.99 including the belt and bolt needed for install. We are also having a group buy on these. If we get 10-19 orders, the price will be $219.99 and if we get 20+ orders, the price will be $199.99 with free shipping to the continental US.

No issues that we have found after 11,000 miles. Its about a 2-3 our install.

Any perf gains noticed at the track(1/4 mile times). Any problems with accessories such as a/c, windows slow to go up/down etc.... I would like to these things before I invest in one.

thanks

Common sense says yes as your giving less power to the accessories

But for me its hard to tell being that I installed it along with Andys Tune :rolleyes:

Typically with most if not all new crank pulleys it's best to let the car warm up a bit to recharge the battery and not stomp on it immediately. Other than that as long as the alternator isn't crap you shouldn't have any power issues with accessories running the pulley.

14rwhp is going to help in the 1/4 mile. As mentioned before, there are no ill effects from the pulley.
