I have an 05 Ultra with 143k and I've been running 95in, stock heads, V&H propipe, SE air cleaner, SERT and 510 gear drive cams for the last 110k. I just installed SE CNC ported heads and I was wondering if there was a better cam to run with my new engine configuration. I do a lot of highway miles , and my RPMs are between 2500-3200. Any suggestions are welcome. Thanks.

 

what comp

 

Tw6hg cams by woods

 

I used the compression calculator on the Big Boyz head porting web site and I think with my current set up my static compression is 10.6:1 and my corrected compression is 9.83:1

 

9.8:1 Corrected can be high whats the ccp

 

whats the cc on your heads something isnt right also are you running dome pistons or flat tops or you must have 9.8:1 corected without your cam chioce if so tman 555 torqster would leave you 9.1 corrected 190 ccp

 

OK, I changed some #s and I came out with this: 9.41:1 static and 8.73:1 corrected. I picked the wrong pistons the first time.

 

Run the calculator again. No way static is 10.6:1 in a 95" motor with stock heads; more like 9.3. S&S 583 will wake things up........

Good, you found the bust. You need a cam with a very early intake close like the S&S 551 or 583 to get CCP up near 190psi......

 

DJI- you're right, I messed up the calculator the first time. New #s are above. I changed out my stock heads for se CNC ported heads.

 

FYI, SE CNC ported heads have the same chamber volume as your stock heads. Couple of cam recommendations were added to my previous post as an edit................
