Thanks for the warm welcome!

I believe so. yes, I think the magazine adds might be off. I don't think the MAF sensor and throttle body would be a big jump, however I do agree with you that the air intake would be the big helper. I also think the thermostat would help out a good bit. I really wish I had the money to add one mod, dyno, add another dyno...but I think the mechanic would tell me to go to hell, lol.

I hope I don't eat my words when I get this stuff, but I think I will be around 364 after the above mods are added.

You asked about the extra 5hp after a tune. Those words came from the man himself, (Lou Gigliotti, owner of LG). Lou is a great guy and very easy to speak with. He mentioned the air intake he had in stock at the time would give me another 15 at least and a tune would get me another 5. If so, that is giving me the 17 in question here. I'll be getting these two things done towards the end of this month. I will follow up with ya'll here when I do.

Great to meet ya. :cheers:

Edit: oops almost forgot. Yes I got no cats. I'm not worried about emissions around here. I got 2 yrs left on my sticker :thumbs: and I know others that passed it with no cats. Half these places don't even care to check for it.

Good luck Chad :thumbs: I hope you make it. 360+ at the rear wheels, normally aspirated, with the most expensive add on being headers would be very impressive.

 

:iagree: I agree with NVR here. Most cars will never see those rwhp numbers, with just bolt-ons. Better go ahead and get your wetsuit on for some deep diving! :lol:
You're just scratching the surface of MOD RIVER. Watch out, if you're not careful, you might get in over your head! :lol:
GO FOR IT!!! :thumbs: :cheers:

My buddy has a 02 and he is adding the same two mods I have plus the black wing air intake. The Black wing is suppose to add 18 hp. We'll see and I will let ya'll know how it does. He gets it done Wednesday (10/15/03)

 

Without headers I would also so you can't get to the 360 level on an honest chassis dyno....I'm about max "bolt-on" right now, and I will be soon installing a pair of long tubes in my quest to see 370 HP at the wheel with a bone-stock shortblock. Currently I am making 346....need an additional 24 to get me to the 370 mark....Header install coming within a month or two....so we will see what the grand total is soon.

Good Luck...Keep us posted

No no
I said headers are OK, i wanted to stay away from heads, for now

 

I've got the set-up you're mentioning but you will probably need injectors as well and some serious LS1Edit tuning (we spent three days scanning with Ease and tuning with LS1Edit). From the RWHP numbers derrived from the cars PCM; I'm pulling 368RWHP.

 

I didn't need any tuning. Depends on how your car reacts to the headers. Every car is different. However I will be getting the Godspeed LS1 edit just for kicks! :auto:

 

I think you might come close, especially on a dynojet.

I would go with LG long tubes, no cats, and eletronic cut outs to bypass your mufflers. You aren't going to gain much out of an aftermarket exhaust. I have the electronic cut outs and on back to back dyno runs they were worth 10rwhp open vs closed.

IMHO a new MAF is a waste. On my friends WS6 it acutally caused the car to act erratic and severly hurt the tuning.

With a good intake, good headers and a basically open exhaust you could come very close with good tuning.

 

My friend with a c5 coupe makes around 360 RWHP. Not only does the HP count, the power band is important as well.

This is what you need if you want to make that much. Don't waste your money on anything else, stuff like MAF's TB's, wires can de-perform on vettes.

-intake (blackwing is the best) with cut shroud for ram effect
-ls6 manifold
-SVO 30 injectors
-long tube headers (must be jet coated or wrapped-tempature is important)
-high flow cats (if not off road)
-x pipe
-cat back of your choice
-175 thermo stat
-NGK 55 plugs
-MAF screen removal, TB-bypass
-engine decarb (not necessary if its newer)
-LS1 edit tuning (most important) {my tuner is the best in the country}

With those parts you will for certain make 360RWHP. I have seen tons of people on this forum that get all this other crap that doesn't do anything for them besides waste money (unless its for looks)

Tuning is very important, and must be done by someone who knows their corvettes like no other.

 

ahahaha, this is the c5 coupe I was talking about. A good example of research and locating a great tuner.

 

If you think you don't need tuning, you are missing out on a lot. That is what Sebrock said to me at first. Then we got his car analyzed, tuner told him he need a tune. Got car tuned, came back with 15 or more HP. Hmmmm

Assuming you are talking about your '98. Answer to first question -- No. Answer to second question -- No, but it should get you close to 340-350 rwhp. The individual quotes you see for each mod component are not additive. It is what you end up with as a "system" and that will usually be lower than adding up the quoted individual gains for each mod. See my sig, I have bolt ons, without a LS1 edit, and dyno'd at 331 SAE rwhp, or roughly 390 hp at the flywheel. :cheers:

 

im barely made 360 rwhp on a 408 stroker fully built with long tube headers cold air intake cat delete true dual exhaust with a x pipe on a forth gen 6.0
