Before
 
   
Suspension:
The front a-arms were replaced with JD Performance +2 Standard Travel A-Arms. Works Triple Rate MXC Front Springs/Fast Mann Racing Revalving  and a Works Rear Shock replace the standard items. Rear travel increased to 10.5in of travel
Chassis:
Pro Armor Full chassis and A-Arm skid shields were used to provide protection, DG Pro V Alloy Front Bumper and the rear grab bar was replaced with a Moose Racing Item.
A WppRacing Steering System was used which includes 909BFB Taper Wall Bars, Fly Racing Bar Adapters(1 1/8 and 3/4 rise) and Grip Lock grips. White Brothers Nerf Bars provide side protection. A Denton Steering Damper was also installed to reduce steering bump.

Drive Train:
The stock gearing was changed from 14/38 to 13/39. A Renthal Ultralite Front Sprocket and a PBI Aluminum Rear Sprocket were used to transfer the power to the rear axle. A Renthal Works Gold Chain replaces the stock chain. The OEM tires were replaced with ITP Holeshot XC Front and XCR Rear Tires along with ITP Pro Series 10x5(adds 1 in width) Front and 9x9 Rear Rims. To aid in stopping a Galfer
Front and Rear Wave Rotor were installed.
Engine:
Stock compression was raised from 10.5:1 to 13.8:1 by replacing the oem piston with a Curtis Sparks/ JE Piston. 110octane Leaded Cam 2 Race Gas is used. The stock camshaft was replaced with a more radical HRC Camshaft. The carburetor has been fitted with a WppRacing jet kit(50 pilot, 180 main, stock needle set on the 5th clip) . An LRD Pro 4 Exhaust System replaced the restrictive stock system along with a K&N Air filter and  K&N Crankcase Vent filter were used. The stock air box lid was modified to increase air flow.

The Venom Ported Head did provide a HP increase at 7200rpms
but lost some hp/tq below that. On the track this set up runs very good .

Also tested was the Ron Wood Intake system and a Modified stock air box. The DASA intake system still provided the best HP and TQ.

This test was with the air resonator removed and a custom plug installed. The mod smoothed out the dip in the curve and made the A/F line flatter.

The first graph was the base line for the test with the DASA Filter installed
The second graph was with a Wpp/Mod DASA Filter installed
The third graph was with a Durablue Foam Filter installed

The last is an overlay of the first test(5/28/06) showing the dip in the curve and the runs from the day.

WppRacing/Wicked Motors Ported Head

 Springs, VP MR8 Race Gas , DASA Air Filter Kit/with WppRacing Mod Filter, 190 Main, 50 pilot, 2 turn open, and 13/39 Gearing

 

The porting was a joint venture between WppRacing and Wicked Motors. Wicked Motors is now part of Watercraft Performance & ATV and will provide cylinder porting and valve work. We are still in the R&D stage and now that we have the needed info, changes will be made and improved with the next cylinder head. More HP will be coming soon. All will be done using the STOCK Carb.
 



I was hoping for 54hp and fell a little short. By having the head ported with a software program it laid the foundation for making changes. Since the head has been mapped ,now along with the graph, we can see what and where the port change needs changed. IMO Its not bad for the first shot 1022.gif

53.02hp / 35.78tq (best HP and TQ)
 

52.74hp / 34.99tq (average)

 Springs, VP MR8 Race Gas , DASA Air Filter Kit/with WppRacing Mod Filter, 190 Main, 50 pilot, 2 turn open, and 13/39 Gearing

 

 I now have the next ported head with the changes made. The before and after figures were installed in the program and it showed about 1-1.5 gain on bottom/mid and .5-1.0 on top. It also had a smoother flow pattern and should not have the choppy graph as the first dyno test did.

Went on the dyno today and the head performed like the program showed



53.72hp / 34.27tq (best HP)
