Miss matched cams

[overboosted1g]

So I have heard of people running miss matched cams like 262 intake and 272 exhaust, or something like that. I was just wondering what the purpose of doing this is?

Midrange torque and streetability

It's usually 264/272

Would a combo like 264/272 help to spool up a Turbo faster?

Faster than 272/272, yes. It's not much of a difference though, maybe 200rpm.

I am using this to illustrate the differences among 264/264 cams, 264/272 cams, and 272/272 cams, yet I am not endorsing, or disapproving of, the manufacturer of these cams. You can determine which cam manufacturer pleases you.

The RPM range is the most apparent difference, as well as their other specifications. Basically, the "bigger" the cam, the higher in the RPM range the cams go. The 264/264 here (stage 1) shows form idle to 7500RPM, whereas the 264/272 here shows idle to 7750RPM, and the 272/272 here shows 1000 - 8000RPM.
