TR224 Cam

Who's using it?

Do you have any audio or video of it?

What kind of HP gain did you see?

Does it idle pretty mild or big?

Hey man, try searching around the forum with the search button.. The idle sound/chop is not solely determined by how big the cam is, but mainly by the lope seperation (LSA) and overlap. You can have a 220/220 cam with a 111LSA, and it could sound "nastier" or "bigger" than a 232/232 with a 115LSA...

Thats a proven performer. If you search you'll see how many people used/use this cam.
It will idle pretty mild but it will have some lope to it. The lsa only has a small effect on the lope of the cam. The more overlap a cam has the harder it will lope

Mainly on LSA? Maybe, but as I understand it, it's based squarely on Overlap. The more overlap, the harder it lopes. Lope sounds like **** to non-car people ("Uh... is your car running ok? You get some bad gas? It sounds like it's going to die"). Lope sounds like "DAMN, what kind of cam's in that bitch" to people who know.

Overlap = [(Intake duration + Exaust duration)/4] - LSA * 2

A 224/224-112 has zero degrees of overlap.

A stock cam is like 199/209-119, which is like, more than negative 25 degrees of overlap, IIRC.

A T-REX has like 25 degrees.

I'm sure someone will correct me if I'm wrong.

It also depends on where the tuner sets the idle. It's going to lope a lot harder if the idle is set at 600 rpms than if it's set at 1,000 rpm's. Tuners can adjust the choppiness of the idle to an extent. I've heard 21x cams that sound a lot bigger than 23x cams. In the sound clips of TR224 cams with a 112LSA, they sound pretty mean to me. I guess you could say they "sounded" a lot bigger than they were. Hell, you could probably make a stock cam sound mean with a small enough LSA
