thanks all, it appears that for what I want, (a quick small bump in horsepower and and easy install) the Blackwing appears to be the winner. Are there any issues to worry about with the Blackwing? Also, I am interested in hearing about the mail order tune from ECS-how can I get more info on that??

Just as effective, but cheaper, is using a K&N custom, flattened conical shape, that connects to the MAF. About $54, IIRC.

If you haven't installed a Vararam B2 on your stock LS1 I wouldn't expect you to get it..I already said the mileage is probably due to more aggressive driving.

Link? Unsure what you're referring to.
I think I know what you mean, just a standard oval clamp on filter removing the entire stock assembly, air bridge...? Hot air drawn from engine bay?

Any open element filter runs you a somewhat higher risk of getting water in your engine (bad). But I've never heard of this from the Blackwing sitting up high type filter, more the Vararam.
Mail order tunes require you pull your PCM (inside passenger front wheel well behind panel at rear of wheel), mail it to them, they tune it, mail it back. Be ready to be without your car for a couple weeks unless one of the tuners is around the corner from you. I'd save a tune until you do other mods.

Really depends. On a stock motor maybe 10HP? I'd wait until you do other mods. I also agree BTW with the other poster about gears... if you're running 2.73, switching to a Z06 3.42 rear will make a great improvement in acceleration (with potentially some highway mileage reduction).

You, sir, are a very bad influence. Shame on you. But thanks for making me think of contacting A&A. Got my car back on Monday...it's killer!

NO. It connects to the MAF before the airbridge. 4" standard MAF on my LS6. Not sure if pre-'01s had different opening. K&N has many custom shapes, but only really large one that fits the space is as I described. Here's a link to one of the pages. http://www.knfilters.com/search/univ2.aspx?id=S0019

Thanks

There is NOTHING Quick and Easy to increase hp. (other than tiny increases)

Air filters and tunes MAY give you 15hp – on an otherwise bone stock engine. Its unlikely that you will feel that – or be able to measure the result of the additional 15hp. (Though it may sound faster)

The LS1 engine is a great platform that responds well to a variety of power adding modifications that work best when done in conjunction with each other.

If you want to actually accelerate faster, and don’t care about useless numbers, change the rear end gears as previously suggested.
Unfortunately – its neither, quick, easy or cheap….

Speed costs money – how fast do you want to go?

Google search 'ECS mail order tune for C5 Corvette' (or anything else), and you will find many threads here and elswhere about your questions.

Thanks all for your responses. After reading the many suggestions here, I have decided that just changing an air filter is not the wisest investment, especially since, as some of you have correctly pointed out - you will not even feel the additional 10 to 15 extra HP. I figure you either have to go big or not at all. So I may end up making a trip to a local garage to see how much HP $5K will get me. Any thoughts?

Quite a bit. For that you can do heads/cam or you can do long tubes, exhaust, and a tune with some $ to spare. I think most people seem to like American Racing headers the best on here. They fit very well and are high quality. Long tubes/exhaust should give you another 20-25 at the wheels. Most cars with headers tend to dyno about 345 rwhp on a Dyno Jet. Since you have a 98, an LS6 inake manifold (about $500) would also help with the headers.

Reducing weight will have similar effects. A nice set of lightweight wheels would help the car both accelerate and stop better.

Interesting, so if i do heads/cam, a tune, and an exhaust and maybe an LS6 intake, I am looking at maybe an additional 25 to 30 hp?

I'm unsure what you mean by "local garage", but I'd check with local Corvette guys on where is best to go near you.
$5000 buys you into a different area, but depends on how much you'll be doing as opposed to paying somebody to do for you (labor is $). Get some used LS6 parts; intake, 243 heads (ensure they have the blue springs), the right cam, headers... you can be up over the Z06's 405HP at the flywheel if you get the right parts.

No, heads/cam = about 80-100 rwhp (with supporting mods)

LS6 intake/headers/tune = 25-35 rwhp (and possibly more, these are conservative estimates).

The heads and cam could cost about 2000-2500 and the install would be about the same, maybe less. You definitely need a tune with that. Since you are there, doing headers would be smart.

The LS6 intake manifold/headers combo would cost about the same, but install would be less money.
