Something I just noticed watching the dyno video again, is how difficult it looks to install the intake. Look how they put the runners on the motor, there are 3 bolts for each runner to attach to the plenum, 2 up top, and one below. How are you going to be able to get to those bolts on the bottom?

I have to update this:

I literally JUST hung up the phone with Patrick. The new VRX is literally the same height as the LS6 intake manifold. To a T... Straight edge... It's identical.

The pics that ARE available are the early versions before multiple and various tweaks.

So, as I stated earlier, the VRX ** WILL ABSOLUTELY ** fit under the cowl of the FBody, no cutting.

That is good news for a lot of people. Any word on how the field "testing" is coming along.

WOW! That is very interesting. Now, how much boost will it hold Think 20psi is too much for it feeding a 416ls3?

F'n sweet! I can't wait til a cathedral port version is available! Did they give you a time-frame?

They're "in the works" so to speak. Of course the louder the masses are will dictate the speed of same. It's on their radar.

So what im saying is the more voices there are, the quicker they'll come to fruition. I think once the test results are out, well, it's just a matter of time at that point.

When I asked Patrick regarding availability of cathedral port versions he said the factory rectangular (LS3-LS7) ports first to market because their high flow numbers are more restricted by the intake manifold. He said it could be 6-12 months before cathedral port versions may be produced. Obviously much thought and testing has gone into this intake manifold design and likely future designs from GM will follow it's design blueprint...

Ford already does....

I believe the ford coyote intake has a plastic cover that looks like a Varam. If you take the cover off the design looks more like an LS6.

NemesisC5

Thanks for pointing that out, I assumed design was similar to Vararam and cover only there for aesthetics.

Nelson Racing Engines has their X-Ram somewhat similar to Vararam product but with dual 90mm TB's. Throttle response of the NRE engine is insane. Not sure if twin 90's are required for performance or just a matter of availability and/or packaging. FWIW...427 CID C5R's, 427 CID C6R's had twin plenum cross rams with restrictor orifices about the size of a fifty cent coin.

Actually, it looks real close to an old SHO V-6 intake although they had high RPM and low RPM runners.

Got of the phone with Patrick yesterday. Great guy known him for
15 years, Patrick Ledford is to Intake Manifold Design as Tony Mamo
Is to Cylinder Head Design. Definitely going to run this on my
Big Bore 396 W/ MAMOFIED TFS LS3, W CAMMOTION LLSR, and
11.75:1 Compression, shooting for 675+ FWHP & 590+ RWHP.

1989GTA

Anything you can share with us on how the field testing is going with customers cars? I have a LS3 based 427 that I want to do the same thing. LLSR cam and hopefully Vararam intake manifold. I will be happy at 550rwhp.

If I have to install tall valve covers for the LLSR camshaft I hope there is enough clearance to clear the Vararam plenums.

Great Question! I did not think to ask about clearance with taller
valve covers/spacers when I spoke with Patrick yesterday. I
Just sent an E-Mail hope to hear soon! As far as I know, no
Customers have intakes yet, but testing is going very well!
and they Hope to have the LS3 Intakes available for sale
in the next 4-6 Weeks.
Are your heads stock? What is your compression and Engine/Vehicle goals,stats, and set-up?

i'd be curious to see how these stack up on the G8's! we pretty much just have RCR intake manifold mod.

"Are your heads stock? What is your compression and Engine/Vehicle goals,stats, and set-up?"

I sent the L92 heads to Texas Speed for their CNC program and to have their .650" lift dual spring setup installed. They are 144# on the seat and 402# at .600" lift and 425# at .650" lift. Stock L92 valves but with their valve job.

Compression is supposed to be 11.4:1 with the JE pistons. I am running 91 octane so I do not want to go any higher than that.

I deleted VVT and I currently have a Cam Motion camshaft 238/244 @ .050" with .629" lift on both. 114 +3 on the LSA.

The car is a 1965 Buick skylark 2 door post. I have a 6L80 transmission with a Yank SS3200 stall. Right now I am putting miles on the car and will have it dyno tuned on April 28. I am expecting around 490-500rwhp and torque on a Mustang dyno.

The car is between a resto-mod and a pro-touring car. It has elements of both. I mainly want a nice highway cruiser with performance in both cornering and acceleration. No power adders in the plans. Just the Vararam intake and the LLRC down the road.

Let me know what you have going on.

NAVYBLUE210

My plan is a LSX Iron Block Big Bore 4.175 X Stock Stroke 396 CI
TFS LS3 Heads (Tony Mamo Modified), CAMMOTION LLSR 243*/249* .670"/.637" LSA 115* + 3*, VARARAM INTAKE (hopefully fits with
Taller valve covers/spacers) Goal is 201MPH in a my 1999 C5
Coupe at the Mojave Magnum 1 1/2 Mile Event in CA.
Need 575 RWHP Between 6800-7200 RPM. Have a small Nitrous
Outlet Dry system, just for insurance if needed.

VaraRam Intake probably worth 30-40 lb ft & 20-30 HP on your
Current set-up!
How big is your displacement?
Do you need to turn more than 6500RPM?
How many Gs are you planning to generate with your suspension?
HIGH RPM + HIGH Gs = DRY SUMP Oil System, Big Bucks!

Hope this intake is the real deal. I need one for my 436 LSX build, just got the heads back from Chris Frank @ Frankenstein Cylinder heads. A stock LS3 intake manifold sucks for my build and I do not have enough room under the hood of my 240Z for a Holley High intake.

1989GTA

That is going to be a nice setup.

I have a LS3 based 427. 4.070" bore with a 4.100" stroke. I don't plan on turning much past 6500rpm. I will get with Kip at Cam Motion for the details. This will be a street car except for a few times going down the 1/4 mile. From another post it looks like I can use my Holley Valve covers with the thick Yella Terra gaskets and T&D shaft rockers. This looks like a go.

Mine is a stock LS6 short block, Mast small bore ls3 heads, a tight lash solid roller, T&D rockers specific to these heads, and THIS intake manifold.

Can't wait!!

I think I'm going to sit back and see how the MSD intake and the Vararam intake stack up against each other before I decide on one. Also curious which one is going to be setup better for boost.
