Reading a bunch of posts saying that an intake won’t do much on an otherwise stock car. Planning on headers at some point and have cat back at the moment.

Seems like the z06 intake in an improvement over base c5 intake. Can anyone confirm that a 2001 z06 intake would work on a 2002 base? And is it worth it? Looks like I can get one for about 100. Need a new filter anyhow so seems like the right time.

 

Technically, there is no such thing as an LS6 manifold . All 2001-2004 LS1 and LS6 have the same intake manifold.

Fill out your profile so forum members know what type of C5 you have.

 

Ah - sorry, not the manifold, I’m referring to the intake air box/filter.
i have a 2002 vert. Will do on the profile.

 

Zero to gain with an air cleaner swap. Stick with what you have until you are ready to make impactful changes.

 

The air bridge & all of the intake pre-throttle body doesn't do much for the LS1/LS6. You can get a Calloway Honker that changes WHERE you get your air supply and breathes more air from the bottom through the radiator shroud & does give you a larger filter area as well. This has shown some gains, more so on modified cars.
The "Flip-Tie" mod also does the same thing for a lot less & you could watch some videos on how to do it. It's a fairly simple mod to do by removing part of the airbox restriction on any 97-04 intake, flipping it 180*, cutting a hole in your radiator shroud, and using zipties or bolts with rivnuts to hold the filter up above the shroud.

On my 03 Z06 it had to add a good bit to my fuel trim across the board from going to a Fliptie. Even capping off the Airpump part was nice as well.

 

An air intake might net you 0.1 to 0.2 second decrease in 1/4 mile time. You won’t notice a difference from 0-60mph. I have a VR intake, headers, exhaust, tuned, 3.73 gears, and 3200 stall converter. I like mods, it’s just a personal preference. In the end, it’s your car and do what you want with it. IMO, best intakes would be Halltech, VR, or the honker. K&N, Blackwing, or a twin filter setup are similar to the halltech.

 

Picked up a blackwing - I enjoy doing the mods even if there isn't a dramatic benefit to performance. Always like the additional growl an intake provides. Headers might be next but a bit concerned with the additional heat and then the need to find a tuner to get the most bang. Something to look forward to.

 

Unless you are going to place a microphone by the air cleaner, don't expect much. There is virtually no induction noise at all. It's not like installing an open element air cleaner on holley.

 

yup, did that to my old 1977impala that my Dad owned and gave it to me in 1995. It ended up with more mods when I got done with it. 350 block, bored 60 over, stroker crank, dart heads, performer RPM intake, 750holley, hooker headers, 350 trans, shift kit, and 3.73 gears out back. Pulled consistent 13.9 at a drag strip, had a mild comp cam in it with a .490 lift. My Dad is a retired auto mechanic. He did the build. He wouldn’t let me have a bigger cam in it. It was a street car, and I was 17/18 years old at that time. Probably would have done even more stupid stuff with a 12second 4 door box Chevy.

 

You want more power? This is what you need to do. More air and more fuel.

To do it right it takes a cam with more lift, better flow Intake and heads with better flow. Everything else is just a small gain you will not even feel. There are superchargers too but the basic area to clean up is air flow into the engine.

If you are not willing to do this you will see gains much smaller and anything less than 30 HP is really not noticeable. Also each part can be assigned a HP but they do not add up collectively. Intakes and exhaust have minimal gains.

If you want even more power you stoke larger the engine and more compression. The same old stuff they did years ago still apply today. Make sure all the parts work together as do you have the right gear for the cam. Do you have an auto? do you need a converter with more stall? Will you gain enough power to need to beef up mounts and shafts etc.

Best to set a goal and then plan all the part needed to build it and then see if it fits your needs and budget.

Also document all the changes with photos and receipts. This will help retain the integrity of the build and add value. Corvettes and many performance modified cars can kill their value even with a ton of money invested if you can show exactly what they did and the quality of the parts and work. This separates the hack jobs from often well sorted cars and buyers like this.

 

Understood - not planning to do too much to increase power. Really just thinking intake, have a borla cat back already and then potentially headers and tune. It already has more than enough power for me, just trying to make it my own at this point. Appreciate the feedback/comments.

 

Do what you want. The gains are there. My A4 coupe did 103mph 1/4 mile bone stock, now it does 111mph on street tires.

Mods, VR, LG longtubes, cats, cat back, tuned, 3.73 gears, 3200 stall. Will be trying drag radials in the summer hopefully. Current best 12.5 sec 1/4 mile. Would love to see a 12.3 with drag radials and loading the converter. I could probably see an 11.9 with a 3600 or 4000 converter, but it’s a street car. 3200 is fine.

All stock internals BTW.
