This might have been discussed already... (couldnt find it) But is an intake a waste of money for an LS3? After reading this http://www.vetteweb.com/tech/vemp_09...t_results.html It sure looks like it is. Is the ported throttle body the better way to go, and just keep the stock intake? Or is it that intakes dont show gains on the dyno from lack of "ram air"

no doubt anytime you can gain less restriction and better mated/matched runners to the heads you will gain performance. Just like adding headers you gain flow, if you blueprint those as well you gain even more. Better, cleaner flow is waht your after. The fast intake is a gain as well. Its just better tuned for the our engines. T-body gains? Well if you can again get better cleaner flow then it will help as well. They are easy to port yourself and so are the intakes if your brave enuf. gains from both? i have seen dynos of around 30 i think?? might be more with the proper ECM tune

Intake manifold or do you mean an air cleaner assembly?

Sparo2

Whether you're talking about an air intake assembly (like a Varararm) or a intake manifold, it's all worth it. I noticed the difference the day i put on my vararam. I even noticed a bigger difference when I ported my intake manifold and throttle body. Anytime you free up restrictions, you're going to gain power.

Now the question is, how do you spend the money. I have about $200 in my intake setup. I bought my Varararm used for $175 a while back and the rest of the money I spent on sand paper, burls, etc...everything to port my throttle body and manifold. Of course, I did do all the work myself so that helped out a lot.

i have the vararam and ported tb with a tune and exhaust and i really could feel a deference next headers and a cam, modding gets addicting lol

Air cleaner assembly

While you may gain little in stock form, its all part of the "grand scheme" and when more mods come, the better it works/helps. Baisc concept of air in/air out. The corvette community is the only performance group ive been in where people dont like using a cold air in general. Id go with one and did on my LS3.

It's part of a bigger picture, CAI will be the first, then you go to Spin Monster and then Kooks and the Corsa and so on $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$.

Agreed..

IMO it's not a waste of money. IMO a true cold air intake is an essential component of one's overall performance modifications. You can't, however, expect a CAI to work miracles as a stand-alone modification.

well, it looks like SOME people are finally stating to learn, 90 mm WILL support 1200HP, I feel this way about headers too.. unless it's an extreme build, the average build just does'nt support cost per HP, the "ram air" is a fairy story too.....

Matt@Texas-Speed

We've seen nice gains from the intake kits, particularly Halltech, even on basically stock vehicles! And like stated, it makes way for more power down the road when you continue modding the vehicle!

BLACK 08

Exactly..

Like above, it's usually the first step towards more power. I have a Halltech & ported TB......so far

Mike's LS3

The stock LS3 intake is a good intake. There is a forum member who was turning 10's in the quarter using the stock LS3/LS7 air intake with cold air. BTW - it was an LS7 engine in a base corvette. What the LS3 intake lacks is cold air. Keeping the IAT's down is the key to preventing timing from being pulled back resulting in lose of hp. I modified an intake shroud cover (Halltech's Beehive) to fit the stock air intake and opened two holes at the bottom of the shroud for cold air. My plans are to keep my car stock until the powertrain warranty is expired.

For those who intend to do further mods, an aftermarket air intake is part of the whole mod package. Stand alone, don't expect much from an aftermarket intake. The stock air intake provides plenty of air for the corvette family of motors - just make sure its cold air

VaraRam Industries

All our units come with a Performance Guarantee - "If you don't like it - If you don't love it - If it does not perform the way we say it will - We will take the unit back no questions asked and pay the shipping both ways! " No waste of money there!!!!!
Thanks

Not trying to be a dick, but stating the obvious...you are one of the few on the forums that actively try and steer people away from performance mods and seem to always try and justify why NOT to install such and such mod. Im not going to get into a forum argument or debate over why or why not, again just stating the obvious and basically disagree with everything you say in general Either way, guess "it is what it is"

I usually ignore your '1200hp is supported posts' but when they are false and misleading to others, I have to jump in.

First the Vararam has been shown to get a 400rwhp car 3 tenths in the 1/4 mile and 3mph on the trap speed which at that power level is about 30HP under the curve when the car is moving that fast. Dennis from this very thread is one such vararam owner who posted his results that counter your 'ram air is a fairy story'. Youre wrong.

Second, you have posted on countless threads that this part or that part supports 1200HP. Sir the FAST intake manifold makes 30HP on FI cars and N/A cars alike. 30hp is 30hp. Some guys max out their head unit and go the distance to make power without super heated over driven head units so they try a FAST. Mr BIG did this with proven results.

Yes the stock intake manifold can appear on a car with that amount of power but that doesnt mean its optimum. What one chooses when boost pressure is so high that it would blow a FAST intake to peices, the stock unit is a better choice but on an N/A car looking for 500rwhp from a 6 liter, you can bet your rear that a ported FAST, Vararam, and ported TB with be responsible in making that car 1/2 a second faster in the 1/4. Bottlenecks in fI cars dont require the airflow when boost pressure overcomes the restriction so the 1200P car you speak of wont need to open up a TB to make that power but a 500rwhp car will see a bump with a bigger MAF and bigger TB. I base this on FACTUAL INSTALLS THAT TESTED THESE THINGS. The TB and MAF going to 100mm and ported TB gains 10hp at this level. I have seen a 100mm MAF and ported TB on a 440 stroker go from 510rwhp to 540rwhp.

As for your header statement, You show me any car running a 1 3/4 header at 1000HP and I'll show you a 50HP jump with a 1 7/8 header. Even as low as 500rwhp the bigger header starts to win out over 5000rpm which is meaningful to certain types of racing.

All these parts are proven to work documented with repeated back to back dyno runs and track runs. If you have factual data that supports your statements please post it. I will consider any input from anyone looking to share personal experience. You seem to be somewhat bashing at times and I dont get why. You can share info in a learning and mutually beneficial way but you seem to always post info like we're all idiots buying miracle tonics at a circus. Its a little demeaning at times.

SpinMonster

Yet another reason to put your money where your typing is. Get it and keep it if it isnt making your car faster.

That would be me and the car actually ran a 9.950 with the stock air intake, stock intake manifold and stock injectors. Like I've said for quite a while now, GM did a lot of things very well with the LS7.

I did once try a Vortex Rammer and unlike most people who do comparisons on different days, I switched it out in between runs one night and only saw a rather pathetic .04 second improvement which is pretty bad considering it cost me $539 and made the car run rough because of the LS3/LS7 MAF sensitivity.
