Difference - MMS and Thunder 224/112 cams? When comparing the TR 224/112 and the MMS 224/112, what are some obvious differences besides the stated numbers:
MMS 224/224 571/571 112
TR 224/224 561/561 112
The TR224 seems to carry more weight on this forum, why is that?
MMS 224/224 571/571 112
TR 224/224 561/561 112

Re: Difference - MMS and Thunder 224/112 cams? I do know that TR cams have some pretty fast ramp rates <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
I don't know how they compare to MMS though <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

Re: Difference - MMS and Thunder 224/112 cams? My MMS 224 gained me 43 rwhp on THUNDER RACINGS dyno. It has pretty quick ramps, dont know the diff, but it helped me bust a lifter.
BUT, if I could do it all over again, I would go with the Thunder cam.
confused yet?
customer service at TR is outstanding.

The duration at 0.006" for both cams is 275 degrees, which indicates their ramp rates should be similar (since the profiles cross are equal at two points the average slope is equal between those points, makes it likely the curves are similar). They'll at least be more similar than either one is to an MTI T1 or B1, which has slower ramps (as evidenced by the T1/B1's 0.006" duration of 280 degrees). The TR224 and MMS224 ought to both be pretty similar to the MTI C1 cam, which also has 275 degrees at 0.006" of lift.
The TR224 comes with either a 112 or 114 LSA. AFAIK the MMS224 only comes with a 114LSA, but I could be wrong (MMS website is *still* down, so I can't double check). I do know the MTI C1 only comes with a 112 LSA.
