Okay... the ctsv if im not mistaken is the only ls car that doesnt have an over the radiator option for an intake. A buddy of mine and myself were discussing our cars to find we had a similar problem. Our cars are both flatting out on power around 5800rpm. My tuner tells me my cam is too small or my intake isnt keeping up... I have a 219/230 .600 .600 117lsa comp cam with cnced ls3 heads... my friends car is a 418 ls3 with prc 237 heads fast etc. We were thinking that the volants and all the others are choking off the motor. Boxes are cut up underneath for extra power with no help from them opening. I was thinking holley high rise and a custom intake pipe... anyone else having this problems on their V?

So if u think this is the problem, y dont u make a temporary intake to test on the dyno and compare. Basically like a 90* silicone coupler with a straight piece of pipe and ur maf. Or maybe try out a different type of maf

Do you have a graph? Depending on your definition of flattening out I would tend to agree with your tuner.

Having said that I do have my own concerns about the stock airbox and am currently looking for a Volant.

i was wondering if a gto vararam or 2010 up style camaro vararam could be modded to work, honestly. I'm planning to do the small bore mast ls3 heads and a custom ls3 intake with ported ls2 tb...I would like the intake to NOT be a restriction point....so yea...same thought here.

you both have baby cams

I said nothing about cam profile I'll be running.

Op and his friend not you.

If you want power to carry further in the power band start with the exhaust

makes more sense.

if you take a look at the intake tube of the volant you'll see what we are talking about... we both have different cubes, cam ,exhaust yet peak at the exact same rpm... the intake tube is miserable

Do you have a scanner, you can verify the theory. Your MAP (kPa) should remain near constant throughout the pull if it falls off you have an intake restriction. I fall from 99-92 through the course of the pull with a FAST 102, Nick Williams 102 TB, DIY 3.5" Intake Tube and the stock airbox. I'd like to try the Volant and see if it does any better, I intend to reuse my DIY Intake Tube.

I think the best answer currently on the market is the Lingenfelter with a DIY Intake Tube but I'm not a fan of how it looks when you pop the hood and if I give up a few hp with the Volant so be it.

Having said all of this, I don't think any of this will change the shape of your graph significantly. I expect it will peak at approximately the same point, just likely make a little more power throughout.

I would love to fab an over the radiator CAI.

I have a Volant intake with a blackbear tune and it rips. Don't have any dyno numbers to prove it but I def can tell a difference.

I got the scan table tune and sent him a log with my stock pcm with just the volant and he thought something was wrong with my intake. Not sure what he saw but he said he would correct it with the tune. So I assume the intake was holding something back or doing something funny.

its been done. unless you just put a smaller radiator in to make space, i don't think its worth the effort.

Any more photos showing under the hood?

What good is an over the rad intake tube if its making two 90* bends ....in order to hit air stream?? Doesn't seem any better than a single 90* bend into an airbox.

I have an alradco radiator... not ditching it... been doing a little btw k and n and my volant. Ill see how it goes...

I can guarantee your cold air intake is not causing the power to flatline at 5800rpms. Thats likely an intake manifold restriction or a bigger issue like valve float or spark issue. It could even be a cam grind issue or timing error when the cam went in.

yeah...it could be something else. I've seen ls6 intakes turn some power for sure....so I don't know. This cheap spectre intake I have on my car has a stupid notch cutout to clear radiator. Tuner said the maf read like crap too but it was tunable. It rips now, previous tune lacked big time. The 2010 camaro vararam leans the radiator back a bit at the top...brackets come with kit. The scoop picks up air right over the top through grill opening. I don't think there is enough room on our cars to swing this kind of intake. If you are worried about intake restriction you can take the lid off the Volant. If the KN has you worried it could be the diameter of the pipe....but if that has to be bigger I would guess you are running a 90mm+ tb and intake?

Im running a ported ls3 intake manifold... doubt thats the problem. My friends 418 has a ls2 tb and fast 92. Both of us flatten at the same point. Recently had the push rod length checked so less likely on valve float. Degree on the cam is a possibility... I have a pic somewhere of how tight the bay is with the radiator and volant. Had to take a heat gun and massage a dent in to clear the top right radiator bolt and bracket. I dont see how im eating all the air on stock cube with a tiny cam. Previous dyno laid down 447hp 417 tq

You laid down 447 with a baby cam?
