Unleashed UTV 820 Kit Results

After 3 weeks we finally got our car on the dyno. Preliminary numbers are 62rhp with stock carbs and the Unleashed intake with out any tuning at all. The AFR is 10.5 after some jetting we should gain another hp or 4.

More HP!

Finally got back to the dyno this week with the 39FCR's and Muzzy Pro pipes. The number before with stock carbs and with the no pro Muzzy's was 62.3 to 62.8HP. The dyno pulls we were making today were 70.6HP. There may another .2or .3 in some fine tuning. Remember this motor has completely stock heads and stock carb spickets. Carbs and Muzzy pro seem to be worth around 8HP. I didn't have time to put the reg Muzzy's on and make a pull maybe sometime in the future.
