well i have been on jbo, and O.E.M. is working on making a manifold for their ld9 m62 project, they stuck with water/air cooling, and ended up doing the following deisgn...





that is it...now that is their proto, but from what i saw the cooling system is staying as is(despite my many attempts to tell them it wont cool enough)


now every one, based on your personaly experience with your m62, how do u think this design will work? I have personally advised them too:

-use bigger tubes, or more of them
-if they are going to run them in 4 like that, to go all single pass
-to add some fins to help xfer heat from air to the water


but what do you guys think? would u run this set up on you m62?

Wow, at least they are trying? lol

looks like someone might have actually made a manifold worse than the stocker. lol.

BLKLS

you know if they pit a small oil cooler in their and ran the coolant threw that, it would work way better. i doubt that would cool the air very much, bearly any contact area. its all lantent heat transfer(sp).....

josh with your expirience with th em62 and the TVS, would u run that manifold on your car?

Josh@ottp

iTrader: (4)

Thats a no followed by a hell no. Like was stated above, there is next to zero surface area to extract the heat to plus it's a 4 pass design. It will fail hardcore, it might make some torque though, but once again hp will be limited.

god man, u mean me LOL at work... yeah i feel the same way, and have been tryign to make suggestions to the manf of that manifold, and they wouldnt listen saying their design would work...so i had to see what others though of it...

yeah those tubes are not going to do squat. who is building this? want to make sure I never buy anything from these guys. I don't believe they understand what they are doing. The stock laminovas would be better than that thing, more surface area anyways. Has anyone tried a brick and plate style manifold like the zr1? or a fin type cooler like mini madness made for the mini obviously?

me and slowswap we working on one using a garret water/air core rated to support 750hp...pitched the idea to vulcan, dont think its getting done(havent heard back from them)...but who knows...

^^^they are making it

damn that is ugly. but i would like to see if it does work properly.

Jn2

iTrader: (1)

you really think it will work? quad pass, little tubes, no fins, our laminovas are set up better than it is

idk thats why i aint gonna be the test car lol

Jn2

iTrader: (1)

me and you both, would hate to be the car running that thing

berto

looks fancy

i bet the welds on the cooling tubing have mad sugar inside. which is going to cut down on flow even more than those jank 90s they are using. i wouldnt put that on my car if you paid me.

wow, just wow. Only in this market...

i dont think you realize this is going on a 2.4 ld9 for the j-body (not an ecotec). there isn't a manifold in production for the m62 to go on the ld9. what they have is hacked up m45 manifold. OEM did make a claim it dropped iat's from 165 to 125.

Jn2

iTrader: (1)

still...165 sounds like DD temps to me...especially if they are unintercooled, temps get in excess of 200*f during WOT w/o a intercooler....now imagine a 2.8" pulley running THAT system....

very true, those 90*'s are killers in flow, some nice U bends would of been nice, o rbetter yet, no bends at all, in one side, out the other, single pass....

There is no *********** on the tubes, and after a little modifying the tubes flow alot more. You are not realizing that we are running a 500 gph pump and a extra large 600hp water to air intercooler. Yes this is a proto kit, but it does work. Also with a little modifying to the tubes to add surface area, or cap one end off and make it a c02 system, it will work even better.

Mark-OEM

Doc

maybe a subie style intercooler instead of those tubes....you could even spray it

cutting tubing on 45s to make a 90 is cheap and hackish and wont flow good i dont care how big the pump is.

check out swagelock.com or hylock.com they sell premade bends. if you need help finding them pm me and ill look um up at work.


you could even get a tubing bender and bend the tubing yourself. a couple back to back 180* bends will out flow your set up easily.

i do like the co2 idea you suggested. ive got a few similar ideas brewing for c02 setups.

I think it looks very rough. The IC wont cool worth a crap like that without fins.

The best part is the equal-ish runners but thats about it.

The Vulcan prototype looks much more professional.

1. No it doesn't work.

2. The tubes are taking so liitle heat out of the system that the large pump and IC are doing more harm than good. You'd be better off with no intercooling. The 2 or 3 deg cooling you're getting doesn't offset the weight disadvantage.

3. The temperature of the intake manifold makes more of a difference than the IC tubes. It's just common sense. There is far more surface area on the inside of the intake touching air than the exterior of the 'cooling' tubes. You'd make more power and have lower charge temps with a colder T-stat in the car.

dohc v6

Thats because their manifold is done. They have not done any testing with it, so they have no idea how it will work.

Humm, I would say you are right but with the IAT temps I was showing it does work. With a better design of the tubes and more sureface area we are shooting for 50% better flow and efficiency.
