REV 1116's or Comp 918's? Hey guys I've finaly decided I'm going to put in a TR224 114 since Thunder is giving us a killer deal on a GP. The only problem is, they are selling a cam package with REV 1116 dual spings cheaper than with Comp 918's! The only disadvantge of using the REV's I can think of is they are heavier, and with the TR224 I shouldn't need dual springs, right? Any opinions on this greatly appreciated!

Re: REV 1116's or Comp 918's? The REVs aren't necessary for that cam and are a bit harder to install than the 918s. I installed them on my car, but I have a high lift cam. Of course, it won't hurt anything to have them, but I say again, they are harder to install. The question you need to ask yourself is... Is the money savings worth the extra hassle? 918s are good to .600 lift. Well over the lift (.561) of the TR224.

Re: REV 1116's or Comp 918's? You really don't need 1116s with that cam. But if you ever break a valve spring you will be glad you have dual valve springs. The inner spring will keep the valve from falling and hitting a piston. If a single spring like a 918 breaks it can result in tremendous engine damage.

Re: REV 1116's or Comp 918's? Other than the added PITA factor on the install, I can't see a reason not to go with them, especially if they're cheaper(!). True, 918s may be plenty for that cam, but nothing wrong with adding in the extra factor of safety. Additionally, I'd imagine the 1116s would fatigue at a sower rate than the 918s over time, which should give you longer intervals between spring changes. Although no one seems to be able to give me a straight answer of when I need to change my 918s with the T1. A longshot, but the only possible negative I could see with the 1116s vs. the 918s might be slightly quicker wear of the valveseats due to the higher seat pressure of the springs (resulting in the valves smacking the seats harder), but maybe I'm off base.
