Has anyone had any problem with lack of air flow in engine compartment using true cold air induction from vents in front of car? Getting a plan together of what I want to do to c5. Going to go with long tube headers and full exhaust, new air induction, getting ready for supercharger. Troubled by lack of air flow with headers and supercharger.

Any input?

 

"Going with full exhaust" ?
Is there such a thing as {Partial exhaust...}

Your use of the term " True air induction, is also questionable... Air induction is a product of air flow to the throttle body, not air flow to the engine bay. Cold dense air is introduced to the Mix ( Fuel air mix ratio via an outside source. )

So in order to develop a plan, you need to understand what is going on under the hood. Use correct terms to seek help from very experience people who hang out here. Many of us Have superchargers, turbos, long tube headers, an no one has partial exhaust. Many use a CAI system to introduce denser air to their engine but no one used CAI to cool off their engine bay. Many will use a heat extracting hood.
Welcome to the forum..

Personally I have opened my fog surrounds and installed a heat extracting hood , also lightening the stock hood weight by ten lbs.

these two features have noting to do with CAI.

open fog light surrounds. Air flows in low and cold... forces hot air up and out the hood vent. Sams as you see on any C5R.



Heat extracting hood.



If you are talking about replacing the blocked off fog surround with a Vararam which removed those blocked off panels and replaces them with CAI ducts. Those surrounds were never open in the first place. The other scoops in the front fascia are to direct air the front rotors.

 

Ditto.....^^^^^^

Heat Extractor hood is a plus. The intercooler is mounted in front of the radiator and gets it's cool air from the bottom (Not from any vents in front) massive HP increase means more heat produced by way of exhaust pipes and radiator temp increases....FYI. If you intend to track your car...get better radiator, if it's just a street machine it'll be marginal.

I take it you are new to the game....research posts on this forum.

 

Well, I have read on here people doing cat back, no headers. People doing headers, plan on cat back later. In saying full exhaust I am implying I'm doing Headers and cat back at one time (full exhaust).
Have also read on here people putting on new air induction pulling air from same place as factory, calling it cold air and being corrected saying cold air comes from outside.
Don't have fog lights on mine, thought the screen was air to engine compartment. Saw small vents in front was for rotors.
I thought being a new member and just getting a plan on what to do would make it obvious I am new to modern corvettes, last vette I had was a 1968.
That is why I post on here asking questions before I make a move.
No I don't know all the new terminology, just learning.
Sorry I offended your delicate sensibilities. Been busy last 25 years, haven't had time for hobby or luxury.
Just looking for input before I make wrong move. Have money to do a little. Just don't have money to do anything wrong.

 

Don't come here complaining about your job sucking up all your hobby time...for a lot of us our job WAS our hobby.

 

We came here to help you and welcome you here and correct a few misconceptions you have. I've been busy for 71 years, yet I found the time to welcome you and offer you some insight into your car... I'm a disabled retired Army veteran, and a retire GM engineer and I have advanced stage Cancer. So don't tell us you have been busy for 25 years.
You have read on here.. this and that, but obviously you never read the 1,000 times Ive said." Be careful who you listen too here ".. So if you are ready to start over...
Welcome to the forum, my name is Bill also known as ET, and we are happy to help you get the most out of your C5

 

Welcome to the forum...IF your heading for forced induction.. ie. turbo, superharger... then you need to really consider ALL the implications that go with that.... AROUND 400 RWHP you need pretty deep pockets because everything changes...
You can do LOTS of upgrades and enhance performance with bolt on mods and a TUNE...
I did a Vararam CIA, Ti Z06 catback exhaust, and a Chuck CoW street tune... It really woke the car up... is it like driving a 600hp car, NO. But it's still MORE car than I can really use on the highway and still can get you in trouble in the blink of an eye...
You do headers, cam, cat back, tune, and you'll be impressed... I think, but then I'm pretty easy to impress lol
There is a learning curve to the LS1 and to all the C5 corvette linguistics, and the acronyms... but, don't be intimidated, keep asking questions and learning you'll get it...

Well said!

 

if you're going to supercharge it then skip the intake because you will get rid of that when the supercharger goes on... I would recommend a dewitts full size radiator and spal fans if you have the extra money when that time comes, anything you can do to keep the car running cooler after boosting is a good thing... the guys I see having cooling issues usually have either a big cube motor, iron block, or both, and any of those will generate a lot of heat when making big power... if you keep the aluminum 5.7 those generally don't have many issues unless something is mechanically wrong in the cooling system (bad waterpump, thermostat, etc) or there is a blockage due to debris

 

Thanks for the useful feedback, knew someone would come thru for me . The more I read and think on it I will just stick to improving air flow, a cam, some head work and tune, its bone stock. A lot more expense than just initial cost of s/c I didn't realize, and don't really want to stress my car that hard. All I really want is a toy to run around in on nice days. Putting it on a dyno soon for base line and go from there.

Thanks again..

 

Welcome to the forum! You could also install a Ram-Air intake=CAI that utilizes the front air ducts bringing cold air into the engine for increase performance. (Vararam) is a well known and used product that a lot of Vette owners run on their cars. Also the Callaway Honker is a well known product. Do a search on the forum and you will get a lot of information. Welcome again Glassport and bring all questions here! I hope your vision and projects yield great results for you!

 

IF your car is an automatic...gear changes can be a VERY big performance boost... also with a TUNE they can change shift points and throttle response which will feel much better...

 

Just because the OP said he was busy didn't imply everyone else on here has been sitting on their *** for 25 years. Jeez. Guy posts up and immediately gets chided for lack of correct nomenclature? Isn't it more important to help with the answer than criticize how the question was asked. To the OP, I can't agree more with the statement "be careful who you listen to". Sometimes hard to wade through the manusha to get to the info your looking for. This is, for better or worse the absolute best place to go to for information advice and help with anything you need for a C5 Corvette. Welcome and good luck with your project.
