Anybody using a Feuling Reaper 525 or 543 cams in a 103
« on: Tuesday, October 16, 2012. 07:01:36 AM. »
Looking at these two cams for a 103 with ported heads, 10 to 1 compression, Jackpot 2 1/2 head pipe, V&H Hi-output mufflers with quiet baffles, Screamin Eagle CVO 110 air cleaner, PCV w/auto tune. Wanting Low to Mid- Range Torque. Also looking at the Woods TW 5-6 cam.

525      1,750-5,500
Intake  Lift 525    4/42 Open/ Close    226 Duration   Lift TDC .099  LC 109
Exhaust   Lift 535   51/5 Open/ Close   236 Duration   Lift TDC .112    LC 113

543      1,900 - 6,000
Intake  Lift  543    15/43  Open/Close    238 Duration   Lift TDC .160     LC 104
Exhaust   Lift  553    56/12 Open/Close    248 Duration    Lift TDC  .140    LC 112

have to think  the 543 would do real good with a bump in compression  a cleanup of the heads and prhaps a good valve job.

I'm also happy with the 574 in my 103, no head work when it dynoed at 97hp/107ftlb. Planning on 107 and heads this winter.

I know that this cam loves more compression, only problem is 91 octane is it around here :( , thinking 10.5 would be a nice balance.

How's the valvetrain noise level?

That 525 is a real strange cam.  Look at the valve events.  Almost no overlap.

I am curious if anyone knows if Harold Brookshire ,AKA UD Harold had any input in the the design of these cams before his stroke?

  Would the fueling  574g be a good cam for the 98 big bore in a carb roadking 328 gearing would have heads done

  Forget the two puppy grinds if you are intent on a fueling cam

  The 574 with about 10.2 would run ok

how much squeeze will that cam take before it is on the edge? will it take 10.8? Safely! Would not want to be on the edge where ya have to dial it down and loss all the performance good $$ paid for, just nuff to opimize the cam,along with the rest of the build.

I set up my 107 with the 574's targeting 10.1 CR in my bagger and I am very pleased with the outcome and tuning ease.  I run 93 octane but here in Chicago it's reformulated blend with corn squeezins and oxygenates.  I don't want to start a fuel debate, some on here think the corn is no problem...well that has not been my experience with higher CR in air cooled engines  :angry:

Lighter bike or different gasoline blend maybe ya might be able to squeeze it more...

Way easier IME to end up at 9.0 corrected being able to dial up the timing to help cool it down then to end up pulling timing looking for ways to keep the ping & heat in check.

The additional performance gains from the added compression is far less then what is at risk IMO & IME.

I realize corrected CR target at 9.1 is not the number that most builders favor here on on this forum but it is my experience learned with money that I would have rather spent on booze women gambling or  :dgust: :idea:  :missed:

i understand not wanting to have motor that is pinging.. seems at 10.1 with the cam your runnning it would be soft down low. forget what your ccp is. ya the detuning a bike cause of compression would be a huge bummer and waste of money.
