Car already has 373's, 2800 stall, flowmaster muffler, msd ignition, HPP to tune gear's, and is a bit lowered. All stock motor & tranny. TC was best babg for the buck mod, then gears............Also has added cooling capacity. With ac off, temp gets about 175-180.

I'd ditch the muffler (you're not gaining much by just a muffler) and replace it with a full cat-back system such as the Hooker Aerochamber.

I also don't see a CAI on your list.

I would personally get a magnaflow catback over the hooker catback. But both are really nice pieces, except the audible noise is very different.

How about some headers too.

leave the muffler for now. Get a cold air intake. It will be a solid 12rwhp. After that get a whole new exhaust system. Hooker, magnaflow, whatever you like and can afford.

Ditch the exhaust and put on a set of long tubes and either true duals or a good cat back, After that do the intake

Cold air intake.
catback exhaust.
headers.
intake and throttle body.

injectors? nitrous? H/C? Rear End?

Better catback,air intake,long tube headers,some suspension, good drag tires and nitrous. Oh and if you can peddle off the stall get a bigger one.

BTC

Even though I have an SLP, I have trouble believing that just a cai will add 12 rwhp.

BTC

Maybe I'm just old, but nitrous just seems like cheating. If the power isn't there all of the time, it doesn't really count in my book, but I'm not a drag racer.

Haha well it's just there when you need it

Like everyone else said get some exhaust (LT's, ORY, better catback) and a CAI. Eventually you will want a higher stall, but you could put it off until you go heads/cam.

in GM hi tech performance they had a 94 TA that was bone stock. It put down 242rwhp, after intake and exhaust it put down 271rw. 29rwhp gain. half must be from the CAI.

BTC

Why must half be attributable to the intake?

slomarao

because ive seen before and after dyno's from a catback and have never seen more than a 10-15rwhp gain.

I have also installed CAI's on stock LT1's and you can feel a small seat of the pants gain.

BTC

Then why didn't you say that initially as opposed to using the GM article as reference? Making two mods, and attributing half of the realized gains to each certainly isn't sound logic. I still have trouble believing that the stock intake is that restrictive. I've installed intakes on other automobiles, and aside from the sound, there didn't seem to be much performance gain at all, aside from manufacturer claims. I'm glad to know that a CAI on these cars falls just short of long tubes in added performance.

My guess is that an intake and exhaust work in conjunction with one another, and that just an intake isn't going to net you 10-15RWHP. But again that's just a guess.

IMO, the exhaust should provide more substantial gains than the CAI, which is why I mentioned the exhaust first.

BTC

I agree.

trex600450

Hello again everyone. I forgot to mention, it does have a CAI.......... I've been told that a full cat-back exhaust on LT1 cars is a waste of money, for the conceived amount of gain. I've also been told that the stock exhaust manifolds actually help keep the low rpm torque "up". As the car is set up now, I barely have traction from a WOT start, and if its even remotely wet, I have to drive the car like a 4 cylinder. What tires do you' recommend ?

RamAir95TA

Whoever told you upgrading the stock exhaust is a turd-burglar. One look at the stock log-type exhaust manifolds compared to even a mid-length header and the difference is obvious.

As far as tires are concerned, for the street or strip? On the street you'll want a drag radial of some type (BFGs, Nittos, M/T). Standard bias-ply tires won't do you much good from a stop (except roast), although they will last 10x longer than drag radials (all things being even). Hooking on the street is very difficult as it is - drag radials will make it a bit easier.

after you get some goodies i would suggest you get the USM HSR Intake manifold with full set up its kinda pricey around $1800 but itll help you tons in the long run. Had a buddy put it on his swapped tpi to lt1 iroc it helped alot..... heres the link if your thinking about it http://www.usmracer.com/USM-HSR-FOR-...N-_p_4325.html
