F14 or Comp XER 281???
I was going to get the F14 (good power with a lot of overlap, cammotion lobes), but someone is trying to talk me into Comp's XER281. Both would be on a 112 SLA. Both cams have durations at .50 of 232/234, the lift is very similar: just under .600. The Comp lobes are more aggressive though, duration at .006 is 281/283, so the ramp duration is only about 51 degrees, which seems pretty aggressive. I have 4.10's so I don't think either cam is too big. I have all the bolt-ons, and expect to add an LS6 intake shortly after the cam, and some ported LS6 heads by this summer. I'm looking to make as much over 400 rwhp as possible, but would like to keep the torque up as high as possible too.
Any suggestions or comments from folks who have these cams or know both of them? Is it worth grinding in a few degrees of advance to favor the torque, or is there a better way, like bigger split for the exhaust duration? Or maybe way bigger lift and smaller duration on the intake (a la TRAK Cam)?
Thx

The comp 232/234 is the TSP torquer. Same duration and lift specs, same XE-R lobes. Many people have made great power with both cams, although i have not seen any direct comparisons. I would think the XE-R lobes have a little more lobe area than the cammotion lobes, and thus should make a little more power. Even though both cams have 9 degrees of overlap, I have a feeling the comp will lope a little harder. For more docile drivability id look at the futral, but for power and sound, the comp.

I have an F14 and the actual specs are 232.8/234.2 .59788/.60109 on 112.1LSA, so it is actually a little bigger on duration and lift than advertised.....all i know is that it is a bad *** cam, i could not be happier with my choice, i would assume based on specs that both cams would perform similarly, however i have heard a lot more proven results from the F14 than the Torquer 2.......and now i have my own results that reinforced all the good things that i heard. Just my .02.

Similar specs, not the same cams. The Torquer 2 seems to have a little less lift, and plus, one VERY important difference: it is ground on Comp XE-R lobes, where as the FMS cam is ground on Cam Motion lobes. Which one you prefer is up to you. I personally like the Cam Motion lobes, a little nicer idle, more power under the curve, and not quite as hard on the valvetrain. That's just me, though.
