We ran Boss's (2) 05RX1's in the wet hay field against a stock 04 warrior with 5000 miles and my ex-warrior with 13,000 plus miles.
The 05's were consistantly 3 to five lenghts behind the stock warrior and at least 10 behind the 13,000 mile warrior. The 05's only pulled around 9600 RPM.
This morning we put the stage two clutch kit on one of the 05's, it was used on a fast 04 warrior last year. It now pulls the stock 05 by about 3 lenghts and hangs close to the stock warrior. It now pulls up to 10200 RPM.
Tonight we will start the updates we used on my warrior last year and do a test in a few days.
