Cams for all 2007-up Twin Cam models & ‘06 Dyna HQ-TC-500-HC Hurricane uses stock hydraulic chain tensioner system. This asymmetrical double patterned cam is an absolute winner as a bolt-in cam. It will increase power across the whole range and is compression friendly too. Designed as a bolt in replacement, it broadly enhances the power curve. If used in a 103 or larger motor (keeping compression at or below 10.5:1, this cam will still be compatible) HQ-TC-525-HC Paul Bunyan uses stock hydraulic chain tensioner system. Specifically designed for use in 09 and later touring models with lower 1st - 3rd gearing and for those who want more mid to upper range power with stock and SE heads. Also complimented with the new 2-1-2 stock exhaust head pipes. Works extremely well as a bolt in for stock SE110 engines. Uses stock hydraulic chain tensioner system. This asymmetrical double patterned cam is an absolute winner as a bolt-in cam. It will increase power across the whole range and is compression friendly too. Intake 18/40 238 .525" lift HQ-TC-600-HC Josey Wales uses stock hydraulic chain tensioner system. Use with compression up to 11:1. Pulls very hard from 3000 RPM up. Good bottom end, very strong top end.

HQ-0034 Hurricane uses stock chain drive Bolt-in cams for 1450 and 1550cc engines using stock or modified heads. Good power increases throughout the whole RPM range. Makes the mid-range very responsive. This cam is extremely popular with the dealers that use it It could arguably be the best bolt in cam on the market if we had the advertising budget to market it properly. John’s Performance in Washington state used one of these in a stock 88 cubic inch 2006 Street Glide using a Power Commander and Rhinehart Tru-Dual exhaust. John made 89.8 HP and 95.4 foot pounds of torque. A very impressive dyno sheet and said he could have got more if the customer would have paid for more dyno time. We have seen the 95 cubic inch motors at 9.6:1 produce 88 HP and 101 foot pounds with stock heads. HQ-0039 Cyclone uses stock chain drive Cams for use with ported heads on the 1450 & 1550cc motors. Also works well in 103s for bagger style bikes. Pulls progressively harder from idle all the way up. Works well with both 9.5 and 10.5:1 motors. Very strong mid-range ideal for touring bikes. Requires our HQ-2007 valve spring kit. (the owner of the company uses this cam in his 10.5:1 95 inch Dyna because he likes the neck snapping torque feel) this cam makes a great bolt-in for waking up CVO SE 103 motors. Timing specs measured at .053" tappet lift HQ-TC-575 Fire Storm chain drive 1999-06 (except ‘06 Dyna) This cam was designed for baggers with compression ratios 9.75 - 10.5:1. It will provide very strong torque figures HQ-0033 Tornado uses stock chain drive We developed this grind back in 1989 for the Evolution motors. It was very unusual for the time and it’s success took the market by storm. Many of our competitors were inspired to *borrow* from it’s design, as can be seen by their own cam specs. Unfortunately for our competitors, we nailed it, they can only come close. These cams are for use with Twin Cam ported heads used on the 1450 & 1550cc motors. Pulls progressively harder from idle all the way up. Works best with 10.5 thru 11:1 motors. Very strong upper range making it ideal for lighter bikes like the Dyna. Also woks extremely well in 103, 106 and 107" engines around 10:1- 11:1 compression ratios. Requires our HQ-2007 valve spring kit. Timing specs measured at .053" tappet lift. HQ-0036-G Blizzard special gear driven type Extended intake timing version of our HQ-0033 series cams. Works best with strokers or motors exceeding 11:1 compression. Very strong upper range making it ideal big motored bikes. Requires our HQ-2007 valve spring kit. Timing specs measured at .053" tappet lift.
HQ-0038-G Storm special gear driven type Extended intake timing version of our HQ-0036 series cams. This is the one for the biggest stroker and large bore motors using high compression. A good example would be an S&S 116 or 124 with compression ratio higher than 11:1. We have seen over 150 horsepower and foot pounds of torque using this cam. Requires our HQ-2007 valve spring kit. Timing specs measured at .053" tappet lift. HQ-0037-G Twin Camzilla Combination drag and street. We made this cam for the HUGE motors that have become popular recently. It works really well with a healthy increase in compression. These cams are not suitable for stock heads. Very snappy bottom and mid-range. Wait ‘till you hear one idle. Nasty! Timing specs measured at .053" tappet lift. |
