my indie builder wants me to try the BW 39 cams in my 88" tc. its a 06' ultra. anyone had em?

 

tell him you will try them if he donates them and installs them for free. That will shut him up.

 

I was set on the andrews 26. he is a coworker and builder on the side. tells me the BW will work better thats all.

 

Go here and click on calculators and you can compare the 2 cams...

When does the intake close on both of them and where do you want your power?

 

the andrews 26 intake closes at 35 the BW 39 at 39. this bike is stock compression and bore, and I want more low and mid due to some loss of that with the true duals. the lifts are same at .49 but the overlap is the difference. the andrews 26 has overlap of 16, and the black widow 39 has overlap of 23.

 

Either one of them will give you MORE power in all areas, the BW will just pull out a little longer is all

 

thanks stafford, thats what I have heard. comes on around 1700 rpm and pulls good untill 5500 rpm.

 

You seem to already know that no matter how you build it, the cam is the heart of the motor. If it's the grind you want, go with it. If you know enough about cams, and the motors potential, have one ground to your spec. Stock material quality is equally or more important to me.
