Most popular mods.....
The most popular mods seem to be: CAI, longtubes, catback, and a tune. I have seen the dyno charts, but can someone tell me what these mods gain in 0-60, quarter mile times? Thanks, EagleEye

)Racing and time trials are as much or more the driver than the car.Learn the car, launch techniques,how it reacts to cold/heat,track conditions, etc.The CAIs seem to give little back for the $$, as well as the cat back, but at least the sound is improved for the $$.

I think he's asking what would be the 0-60 gain when HE drives his modded car. To compare the performance improvement, we should fix a driver to the same person, IMO. If an average driver can cut 4.5 sec for 0-60, what would he do after 50 rwhp gain?

In my experience, the faster you go, the harder it is to get faster. If your car stock is 4.5 0-60, it may take 75hp to get it to 4.0, but then another 100hp to 3.9-3.8. I cut a 4.0 in my bone stock (except for k&n filters) c6 Z51 using a comp g meter I borrowed from a friend.Accurate or not, to shave that to sub-4 sec, it takes more then just HP, because you're likely to fishtail or spin with more hp. If he wants to cut time on the street/strip and doesn't drive in the rain, get a good pair of drag radials and run low psi.Two of those bolt ons he listed show great improvement on HP,the headers and a tune, two do not, cai and cat back, together,all four may cut .2-.4 off a 1/4 mile or drop a 4.5 0-60 to 4.3. The tires alone could do that.

, because he probally will try to kill it and turn it sideways or forget to take off TC or something else.An experienced driver with 50 extra hp may cut a tenth or two off a 0-60

). I sometimes feel my Z51 tries to sideways when I step on it hard.
