Some some pics of manifolds I've built over a couple months.

Have a new one sent out to my buddies at ECS they will be receiving next Thursday!

The intercooled ltx manifold is for my personal car, 2016 SS Camaro, the turbo kit in picture is what is going in the car with a 416 stroker build.

Pretty cool looking stuff. Have any IAT data pre/post boost for intercooler setup?

0G1Pro

I should within the next few weeks.

Should be getting engine from machine shop this coming week and Circle D converter on the 7th. Then put it all together, in the car, and hook it all up and dyno etc.

Will post data as it comes.

Peace of art bro, really nice work and perfect finish,

I know a little about manifold design... I like the "humpback" design of your personal manifold, really helps slow down the air and equals out the airflow to all the cylinders...

How long are the intake runners!?
Any taper in the runner?
CSA size?
Plenum volume size?

Judging by the pics only, I would believe this would work better then Procharger's manifold for most Centri builds I see and work on

My personal intake is the one on the ltx engine with twin turbos.

It is bottom fed intercooler so that I could use the longest runner and keep everything under the factory ss camaro hood (the humpback manifold is a coyote intake for a direct drive vortech car)

I generally don't discuss intake manifold design to much but I will say what my manifolds are.

Currently my newest design manifold I just shipped to ECS is the longest runner manifold (next to stock) that will clear a baseline c7 hood.

The runner length is 5.5" (center line from head flange surface to vstack entrance)
Plenum volume is roughly 450ci

This design does not use a tapered runner, a tapered runners great csa at the entrance changes the harmonics for primary length tuning. Depending on the % greater at the entrance you have to run an even longer runner to get the same harmonic tune for the desired rpm range. Basically in english if I did it I would need to use a 1.5" longer runner to get the same powerband and we are already tapped out on hood clearance.

Manifold that shipped to the ECS guys, should be our final version for C7 stock hood friendly manifold.

Not a vette but pics of my camaro.

Older design (4.5" tapered runner) installed on c7 vette with A&A Kit

Newer design is all same physical dimensions on the outside just with 5.5" non tapered runner for greater velocity (better mid range)

Also newer design has slight differences to tb snout to better mimic the factory intake manifold tb placement.

Old manifold (as pictured above in c7)
vs new manifold shipped out

Old was 4.5" tapered runner, new is 5.5" non tapered.

Clears baseline c7 hood, new mimics factory tb location much better.

Chart 1 Stock VS G1 4.5 tapered

Chart 2 G1 4.5 tapered vs MSD

Chart 3 comparisons

Notes:
there was zero tuning done between manifolds. If you look at the afrs on the comparisons page our manifold ran the leanest during the mid section where it lost power.
Also notice the g1 registers more boost on the map pickup. This is a more accurate map pickup than a msd or stock located map. With the stock and msd the map is shrouded on the plenum wall while the vstack entrances are in the center of the manifold. This causes the plenum wall to be a lower pressure zone. Our map is right beside the rear vstack entrances, what your reading is what the engine is actually getting.

The newer 5.5" non tapered runner will pickup tremendously in the midrange vs this old 4.5" tapered design.

This is hardly a engine combination that needs the manifold. The manifold is meant for engines that actually need greater airflow. Big cam, big inches, big boost, bigger rpm or any combination is where this manifold will shine.

Also take into account the inability to add additional fueling to the stock manifold and the msds likelyness to start splitting and leaking boost under higher pressures and then the additional costs of other producers out there and we think we have found our sweet spot middle ground.

Do you have anything for LT4? Like that bottom feed with cooler and injector bungs in rails for a Zo6?

0G1Pro

All my manifolds are already dual bolt pattern lt1/lt4

G1, any more details on the intercooler LS intake? What sized core is used? The runner 'look' small do they pose any restriction?

Any plans on doing a intercooled LT intake? I know LPE has one out but heard it's like waiting for santa to get one! Lol

0G1Pro

That is an intercooled lt manifold (specially for my Gen 6 SS Camaro Parts Development Car)

The runners are no smaller than the runners on the alternative sheet metal/billet intake manifold out there. They are just double the length making them look smaller.

My manifolds car a 2-4 week ETA. Hardly a Santa wait time.
Cores I use Bell Intercoolers located in San Antonio Texas. We are in Houston/Katy area so when ordered the cores arrive within 1-2 days. Sheet Metal parts I have proprietary cut at a laser/brake press shop for me, they carry a 1-2 week eta and all cnc parts we machine in house. Also all welding is done in house by me.

The core used for the LT intercooled intake manifold posted above is 15.5" long, 6.1" wide and 3.5" thick. The roof of the plenum to the plenum is 8" if the manifold is sat down on a table, it clears a stock ss camaro hood with about 3/4" to spare. I have not yet test fit in in a z06. If a shorter one is needed to be made I can reduce the plenum height by shortening the runner length and reducing the plenum thickness.

I've made a slight design improvements to the intercooled manifold for better fitment at the pcv nipple (it is close right now but you can get a hose over it no problem) and in other places. The first manifold always has the most flaws for obvious reasons...

That looks like Jesse Alley's intake. Are you the new owner of it?

Looks great.
