I hope you aren't talking about racing on the streets by removing your front swaybar. Hell, Civics will beat you on a road course. If straight line dragging, then go ahead though.

Anyways..

Put a straight pipe through the core of your cat, your setup is only hurting power over even a non-altered hi-flow cat. How about a blower?

Put some real springs on those Vortec's, those Z28 springs aren't going to cut it. They will float the valves really early with a cam like the XE274. Get real an put the springs comp recommends for that cam.

A blower with 9.3:1 compression? Hardly worth the money unless he goes to race gas. Which I dunno, maybe he intends to, but otherwise, a big waste of money in my opinion.

that's not much compression at all for a street blower. i'd recomend putting on a 144 holley blower pushing around 8-10psi of boost. the only next step otherwise is more weight reduction and going through the engine again with more cam, compression, and better heads.

Put a cold air intake set-up on it.

how do you put a cai on a carbed car? in this case it would be better to use an open element wouldn't it?

you could also change the heads from vortec's to fast burn's. less weight and more flow.

as for the cold air kit, it can be done with a cowl type hood or hood scoop sealed off to only take in outside air. the custom ram air set up also works well.

The infamous dual snorkel set up comes to mind.

Randel, you could get away with a blower on that set up, just can't get crazy on the pulley sizes.

89 formy... You need to kind of set limits here. BBC or a stroker come to mind. AFRs. Nitrous Oxide is another, what exactly are your goals and cash limits?

Yeah there really isn't much to do besides working the heads over and getting boost (or nitrous!). Change rear-end gears to 4.10s? Change the valvesprings as mentioned. If you get the heads worked over, get a 3-angle valve job. Rebuild the motor with around 9.0:1 dished pistions and get blown.

Yes, a CAI will give you a little bit more power if done correctly, and like I said in my first post, un-gut that cat! Either by replacing it with a hi-flow 3" cat, replacing it with a 3" piece of piping, or cut the cat open and put a piece of 3" pipe through the middle of it and weld it back up (if you have to pass a visual or what-not). The way it is right now is only creating back pressure because the gas gets VERY turbulent inside the cat when it expands into a larger volume area and has to get forced back down into 3" piping. Just keep it at 3" the whole time and you'll get a noticeable difference.

I see a nice 1.9x 60' time, is this with slicks? If not, get some!

Also, maybe invest in a new transmission or a overhaul of your current one with some stronger parts. Those WC T-5s are only good to about 350lb-ft torque unless you are very gentle with them, aren't they? You have to be pushing at least that much torque with this setup..

EDIT: Wow, I just noticed your 1.9x 60' time was on street tires. That's amazing for street tires and a manual! And I see you bought some drag radials, so that should help ya out even more then. Forget slicks for now (or at all with a T-5 I guess, could put too much force on the trans/stock rear if you hook up with enough power)..

Within your set up. Damn.

Victor Jr. if they have a set up for the vortcs, better headers, get rid of the gutted cat, or put the pipe in it as suggested. Power adder next. Suspension mods would probably give you a big gain as well.

More suspension ideas..
---LCA relocation brackets
---Aftermarket body-mounted torque arm (stronger, and less wear on tranny)
---Poly bushings all around (Energy Suspension Hyperflex)
---Poly transmission mount (should be included in above package)
---Drag launch springs in rear at least
---Drag rear shocks

All of those should get you some more "stick" and should improve your 60' even more.

Start cutting weight. Drop backseats, any engine bay stuff you don't need (A/C, smog, P/S and/or convert to R&P steering). Drop spare tire/jack. If you have T-tops, drop those out for the race (as long as you have supporting suspension mods). Go to a light-weight fiberglass hood and front bumper cover, fenders, doors, etc. This stuff will get expensive though, but will cut probably a few HUNDRED pounds off..

ok guys your rigth I was unclear. I am not into power adders, I'm more of an all motor type of guy. My goal in the end as of rigth now is run high 11's with this car, The motor only has around 2000 miles on it and everything is brand new inside, I know that with my heads and my cam I can get low 12's out of the car if I put a holley on there, So pretty much I am just asking if anyone knows any other little tricks with these cars to help me out. I will be partialy gutting the car soon and I figure if I can hook with tires theres no need to do suspension work beyound what I have right?? Also the trans ha sa fresh rebuild on it and so does the rear, I was thinking of putting a turbo350 in it later on down the road though..

would pulling your t-tops make you faster? wouldn't the added wind resistance slow you down?

Yea I know, you could easily run some boost on that, just not a heaping pile of it, I just thought maybe there were some wiser options, that's all.
