I have a 98 Z with 82,000 miles on it and it doesnt perform like I think it should. With MACs with ORP, Whisper lid, 3.42's, Yank ST3800, and a TR224/561 cam I should be able to eek out a 11 second run. The best I can get is a 12.07 @ 112 with a 1.69 60'. Raceweight is 3550.

When I see you guys runnin 11,s with bolt ons only I gets kinda jealous. Do you guys honestly think a cutout will help in this?

I am runnin the stock Z catback. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

What I am confused about is the 60' I should be able to pull a 1.60 if not a 1.5 with this setup but I am not.

Thanks, Stu

BTW: this was in 57 degree weather with 73% humidity at Cecil county in Maryland.

catback or cut-out will be worth 2mph on your setup. What it's worth in terms of E.T. is up to traction.

also, most bolt-on 11 sec. A4's have skinnies up front and are in the 34XX lb race-weight range.

I am running the same exhaust setup as you are except I have a cutout. For me the cutout is worth .10 - .2 in the 1/4.

Get the cutout and get in the 11s!

My race weight is 3350.

I guess for 35 bucks it is worth a shot. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Maybe 3 tenths for me with the cam if it is worth 1-2 for you J.

I guess I'll be callin Speed Inc. tomorrow. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Alot of those times you see are cars with weight reduction. Throw on some skinnies and ET streets and you'll have 11's. The other suggestions here are good too.
