« on: Saturday, December 17, 2011. 07:29:25 AM. »
Was looking at the crane site and see they have  whqt the3y call the 290. 570 lift and  a 42 intake close.  anyone have any experiance with this cam and what compression will it take to make it do what it does best without detonation??
Thanks

I've run this cam in 2 bikes.. One was advanced 2,  88 ci SnS evo create motor, another is a 95 ci road king..  Still have the road kink..  I would expect that it works well at about 10.2 to 1 and would provide a nice power band..  I'm running 10.8 to 1 and it can ping a bit when the temps get over 100.. Not sure about the chain driven version but the gear one rattles the valve train at idle a little when the motor is hot.. Running down the road sound is good.  Gears are tight.. In the 88 ci evo the cam was dead quiet. Cr was about 9.2-9.6 to 1 in it.. Worked real well there with staggered dual cycle shacks on a softail..

I have the EVO version and love it... It hits so much quicker then the SE57 I had in her with the 10.5 forged pistons in her....

was looking at  the cam for a 103". shoulld run decent  with a  little head work and a a decent exhaust.. A/C. imagine  on a honest dyno it should just break 100hp and a little more tq.   i friend told me  the valve train is very quite with this cam on a 96" and a 103..
thanks

The 290 is not noted for quiet operation

I have worked with it a few times @ 9.0 corrected in various displacements,... no complaints.

did you experiance any noise with the gear driven or the chain drives?? have heard where the  gear drive can make a bit of noise at certain rpm's like a lot of other cams. and tquite with chain drives!..
what kind of numbers can a person expect on a 103" with your heads with the 1.94 intake ? of couirse decent A/C and exhaust, also a good tune
Thanks

IME build an engine for a guy who has a focus on "noise" and "noisey cams" and the engine will be noisey no matter what cam you put in, even putting the stock cam back in will be "noisey". You can never win that one.

>what kind of numbers can a person expect on a 103" with your heads with the 1.94 intake ?<

260 @ 28" on the intake 220 @ 28" on the exhaust.

what about those of us that don't focus on noise, but have the ability to know the differance between  a lot of clatter versus a little ticking somewhere in the rpm range?  we all know harleys make noise. i think!
now any idea on HP and TQ. on the question.. flow #'s i do not fully understand
Thanks
