Might be a dumb ? but...
 

If anyone done it and timed it, about how much time would you shave off your quarter mile or 0-60 by adding any type of intake? Just looking for a ball park.

Thanks again,

Actually I'd like to know myself. I can find how much gains in hp/tq everywhere, but actual times I've never seen.

Btt

An intake alone will not shed enough time for you to notice.

So intake and exhaust will do almost nothing for you, if that's what you're after. May look at drag radials, my car has 315 NT05Rs on the rear end and she hustles down to 60mph and down the 1320 faster than ever!

Nothing happened with just the intake other than about a tenth of a mph in the quarter. Exhaust with intake picked up almost 2 mph in the quarter but the ET slowed quite a bit. Intake spacer from JacFab got the ET back and then some. I have all my results in the ARH no cat threads...

depending on intake you might not gain anything. even the best intakes will only net you 10-15 rwhp which is not going to help your times any. exhaust nets 0 pretty much unless you go hi-flow cats. there is a difference in performance with some intakes but in the 1/4 mile you will not really notice it. running 91/93 may help with those mods, may, not certain tho.
