This is just a great motor, plain and simple! Well maybe not stock, but boy oh boy does it have potential!!! By adding our high flow performance y-pipe and Fatt Azz single pipe alone, the power jumps up 22 horsepower! We have found the '07 models typically make around 169-170 HP stock so with a 2.5 degree timing key and full exhaust that's around 193-195 HP!! Crazy, crazy power for just bolting on an exhaust system and timing key! Now other companies have had pipes making similar horsepower, but our pipe just has so much more grunty torque it's nuts! We include a pair of our special exhaust valve spacers to increase the mid-range power by another 15 HP and that's part of why our pipe smokes the competitions. This is because the exhaust valves open at 6800 RPM and when they do the power just skyrockets, which is good, but hard to clutch in the mid-range. By using our exhaust valve spacers, the machines are able to pull much heavier clutch weights, which in turn puts a lot more power to the ground because of the much broader powerband with so much torque. So you get our pipe and manifold, offset timing key, billet big flow intake on the M/CFR or bullseyes on the F1000, a Power Commander EFI controller, and our Stage 2 clutch kit with adjustable weights and overdrive secondary components. Now you have one bad muscle machine!
Adds our billet head kit. If you opt to add our pump gas Billet head and Boyesen Rad Valves we were getting 200-202 HP with stock cylinders and over 140 lb/ft of torque!
This is where we go big! Add our cylinder porting on top of the Stage 1 and 2 kits. Gains are typically in the 9-10 HP range! Be sure to box up your cylinders and exhaust valves with care and send them in. Turnaround time is normally 8-12 business days. We can also have your cylinders repaired if needed. Stage 3 also comes with Boyesen Rage Cages for added power and mid-range.
At Dynotechresearch.com for independent dyno testing this kit produced 213-214 HP and 143-144 lb/ft of torque! We have also found that the ported cylinders really like the larger 56mm throttle bodies producing another 5-6 HP! Hold on! This is the ultimate package for your machine! This motor is just making crazy horsepower with stump pulling torque and an extremely broad powerband from 7500-7900 RPM. It just loves to be worked hard! Be the king of the lake or the king of the hill
