Just curious what you guys think of these intakes? I'm looking at maybe getting rid of my LS6/Stock TB and going this route. Car has a F1A on it and it is leveling off before it even reaches 6k, more like about 5800. What hood on a camaro allows you to use these intakes? I have an Ultra Z hood currently.

What cam are you using ? That will have more impact than the intake.

Running the "EPP" blower cam. 232/240

Yes I would run a Holley High ram. The LS6 will do a legit job for that RPM though.

Far as clearance your wipers will be gone.

I figured my LS6 would be fine too. May be this thing has a crack somewhere. Power fell off on the last setup too with the 6 speed. The intake is only 11 years old.

LS6 shouldn't be having issues, definitely check for leaks. Also, I would do the Pro Flo XT if its a street car, you would keep most of your cowl intact that way, it would also provide good low end torque.

Another option The holley Mid ram Gives you about .64" of extra space

if it levels off... it means you have a restriction and your airflow is stalling out...meaning, you cant force more air in that it can flow.

the ls6 intake is done by 6200 anyways, so upgrade to a new intake
and I would guess that the Heads and/or intake is probably your restriction.
stock TB isnt helping either...

the Hi Rams are great, but dont expect a bunch of low end torque...they are designed for upper RPMs
3500-8000 dependent on your cam choice...and it will want a much lower LSA than an LS6 intake wants...think 108 or 106....which isnt always supplimentary to a supercharger...

you are going to need a 3" or 4" cowl hood for sure with the Hi-Ram...

I have the pro flow on my truck. Its not there for performance though lol, just for looks. And if its missing any low end, I wouldn't know about it. Truck is nasty on the bottom.

If it's cathedral it likely won't fit unless you start cutting at the windshield or space the k-member down. The cathedral version of the Holley Hi-Rams are 1/4" taller than the LS3 versions (which is the one I had on my previous car and it barely fit, it was like almost touching the windshield).

For the above comment about the Pro Flo ^^^ You still have to cut the cowl a bit and you still lose your wipers with either intake.

Some pics of my old car... It's sitting a little lower than it should, I didn't have motor mounts on in this pic and the motor was just laying on the k-member so it came up about 1/8" higher than the pics.

If I remember correctly, I think stangklr got his to fit under his hood in his camaro by spacing down the k-member. Whatever hood that is... I think the VFN 3" hood.

I have the proflo & it defiantly pulls past 5800rpm even with the tiny cam I have in it I shift around 6200-6300rpm. Cant really comment on how it compares to ls6 intake since its the only thing I've ever run on this combo. It doesn't feel like its missing any low end.

Ive got TF235 heads, I hope they arent a restriction lol.

I appreciate the info guys.

I may go with a super victor and an elbow. Im keeping my options open.

KP ran 8.8 something with the same cam, an F-1A and an LS6 intake. I'd look to see if it is cracked. Bob

Or also ensure the valvetrain is in good order to handle the rpm's

I have the proflo, and even on an N/A setup, my HP curve is FLAT past 5500, and I pull it all the way to 6800rpm without the power dying off at all. I like the Pro-flo XT manifold, but one thing to keep in mind though is that with the ProFlo, Edelbrock pretty much forces you to run their rails and TB. I don't know if the Holley is the same way. It seems like everyone I have seen has the Holley rails in addition to the intake, so it might be true as well.

GLS

My Hi ram came with rails, and i would look into the mid ram. I would have gotten it if i were not running ls3 heads just for the fact that the intake wouldnt be so close to my windshield

I can attest to this. The XT holds pretty steady up high. This is the pro flow XT on an LQ4 with the Isky triple 12 cam and boost:

the holley comes with their rails. I have fast rails on my proflo but it was not a direct bolt up, I had to fab some small brackets to make them work.
