cams came after the race header. But the cams and the CAI were installed at the same time. Beware though, you lose a little toque in low RPM with BOTH, actually, with all three of these mods 4-1 header, crower stg 2's, and the CAI. It might be different with other cams though, Im not sure.
I definately felt a loss of torque (low rpm) when the cams and CAI were installed at the same time. But the high end was worth it
ok, let me rephrase my question.
As of right now, i have an OBX short ram intake, and an OBX muffler. Not much to smile about engine wise. I plan on an AEM Cold Air soon, but have heard that cams are one of the best mods for your money. I am going to build moderate to high compression, and go all motor on this engine. So, with this in mind, being the CAI and little else, would it be wise to go with cams now, or is there another part that should be considered first?
i also have the gude cams. like someone said earlier its all in what you want to do with your car.and how much of an concern is with a smooth idle.
my car idles pretty choppy. but i like it. and its really not that bad for how big the cams are.i would say something like this do some research because you dont want to get stuck with something you dont like.
Reground cams are cams that use a finished stock cam and put it back in a grinding machine to change the profile. They reduce the base circle to increase the lift. By reducing the base circle, you increase the gap, or clearance between the cam and the lifter. You have to use thicker buckets, or shim the stock ones to make up for the added clearance. Thick buckets and shims add weight, which is the opposite of what you want. Regrinds also can suffer from excessive wear if they are not rehardened. When a cam is made, they are hardened to reduce the wear. When you regrind them, you grind through the surface hardening. If that isn't done correctly, they will wear quickly. Reground cams are not always bad, but there is a better chance of them failing.
Cams from major manufacturers like Crower, Crane and Kent use blank cores to start with. These are the same type of cores that the OEM, Ford for example, use to make the stock cams. They are usually higher quality and hold tolerances closer to stock so that excessive shimming is not usually needed.
Regrinds are usually done when blank cores are not available such as antique, or uncommon cars. If blanks are available they are the best way to produce performance cams.
