TR 224/227 Pros and Cons
Ok guys I have a 00 SS M6 Lid, LT Headers and SLP Loudmouth. I would like to be supercharged in the future (long time from now). Will this cam be good N/A until I can afford a blower in about 2 yrs?

Read the "sticky" cam guide.

There is a hell lot more to LSA than just "choppiness"
But for the lazy ones, here you go:
LSA is defined as spread in camshaft degrees between the intake centerline and the exhaust centerline.
- Overlap is the number of crankshaft degrees that both the intake and exhaust valves are open as the cylinder transitions through the end of the exhaust stroke and into the intake stroke
- LSA is ground into the cam and cannot be changed without grinding a new cam
- Bigger duration cams will have more overlap then a smaller duration cam even if both are on the same LSA.
- The key to making overlap work is maximizing the power in the rpm band where you want it.
- Long overlap periods work best for high-rpm power. For the street, a long overlap period combined with long-duration profiles combine to kill low-speed torque
- Reducing overlap on a long-duration cam will often increase midrange torque at the expense of peak power, but if the average torque improves, that’s probably a change worth making.
- Many enthusiasts purchase a camshaft strictly on the basis of how it sounds. A cam with generous overlap creates that distinctive choppy idle that just sounds cool.
- While doing my research on the T1 I cam across this dyno in which if I recall Tony (Nineball) stated that the blue graph was a T1 (112 lsa) and the other 2 where a B1 (114) lsa. 112 vs. 114
- What really affects where the cam makes the most power is the intake timing events. What affects drivability most is the exhaust-closing event.

Just to make sure, you do have a manual, correct?
I wouldn't worry about how the cam will act with boost if you don't even plan to get the blower for two more years. Considering how many other mods you will want before that time and how much a blower costs I'd just get a great NA cam for your current application and swap cams with the blower.

Sorry for the disruption. Good luck with the cam.
