Rumor is we are making an intake manifold

And spray meth. Long-term solution that'll keep them clean. And all sorts of added benefits It's also the perfect time to install an OCC. The process is literally like 10x easier with the IM off.

 

Alright here's some data!
Average Runner Length: 8.75 in
Runner Cross-Sectional Area: 2.60 in^2
Flow per Runner @ 28" H20 below (Intake Manifold Only):
Note: the engine shop labeled the cylinders backwards

 

So when's the release.

 

So on the one hand we have the Damond ST IM adapted kit, which costs $449 (with TB wiring harness extension and modified ST manifold options included), plus at least $250 or so for the under-routed hotpipe, custom-figuring out the coldpipe situation, has no PCV return (need EGR block-off) and VTCS disabling, and offers ~330 cfm/cylinder with ~2% variance between runners. So the out-the-door cost would probably be in the $750-$800 range with incidentals, etc. This actually brings the price in the same range as the JMF.

On the other hand, we have the CS. Although it flows ~275 cfm (as opposed to 330), it has <1% variance between cylinders and still flows a LOT more air than the ~200 or so of the stock IM. I'm curious, @Barett@CorkSport, will this retain the PCV return fitting and work with FMIC piping that descends between the IM and the radiator, or will under piping be needed also? What about with a thicker radiator, like the Koyo? How about needing TB extension harnesses for the wiring? Will it include a solution to address no VTCS CELs? Ports for supplemental PI or methanol nozzles? And finally (something I'm sure we all want to know), what price point range are we looking at?

 

According to their page

 

yeah, it's is a drop-in replacement to the stock IM. this doesn't need no adapter plate, TB extension, have to go under route like the DM.

also when are you going to release this manifold?

 

I don't see that verbiage on the page you linked. Am I just blind? (And I believe you, I just wanted to see the original content.)
Just saw the CS blog saying the price would be ~$725. That makes it the front runner, since it includes everything needed. And for 275 cfm/cylinder (up over 200), that's an amazing boost. It's not the 300+ of the JMF and FoST ones, but on a 500whp build, this would still be a great choice. You may want one of the others for an all-out 700-800whp build.

Paragraph right under the first pic sir!

 

Hey Redline,
The CS IM does retain the PCV port (or you can get a plug for it instead of a rubber cap) as well as mounting locations for the TMIC. The only mandatory losses are the EGR and VTCS which is a common mod for even the stock IM, however we do not have a solution for the CEL's.
As stated by a few others, the CS IM is designed to be a OEM replacement therefore maintaining the TB, PCV, TMIC, and packaging constraints.
This may be surprising, but the CS IM actually provides more room between the radiator and the IM. This allowed us to located the runner meth ports on the front of the IM instead of the top so that the customer could still use a TMIC. dale_gribble should be able to confirm this, especially driving an MS6.
We do not provide provision for PI on the runners other than the 1/8-27 NPT meth ports.
I can't give you an exact price point right now, but I can say that it will be at or below the price stated in the blog...and the idea of a pre-buy is interesting...

EDIT: dale_gribble in MSF (not MSO) is a beta tester and has posted pictures.

 

Sweet! So, I'm guessing you made provision to plug in the stock vacuum line, etc., too (like near the intersection of runners 3/4 on the stock IM)?

 

Yup. Ports, hardware, and lines for the brake booster, EVAP, and BPV along with an extra port.

 

Is there a provision for mounting the vcts solenoid? The cel can be fixed by simply leaving the module plugged in, no need to actually do anything. If there was a provision for mounting it somwhere that the stock wiring would reach it would completely solve that problem.

 

nope

 

are you saying it simply needs to be plugged in? bc the little valve can come off the black box, or does it still need the vac lines hooked up?
[doublepost=1470880056][/doublepost]I think under the price point stated in the blog would be a good start, since when you think about it, it removes all emission stuff which already limits the amount of buyers

 

Looks like you need to put in some overtime this weekend then.

 

Let me get out my chisel to modify the mold real quick...

 

LOL... I do think the vtcs box could be mocked up tho

 

GEEZ GUYS! I'm trying to get you all the POOOWWWAAA and you're wanting provisions for VTCS...

 

We appreciate it! It's just that some of us can only have so many "not readys" for emissions, so being able to have the actuator bolted up/plugged in is helpful, even if it's not doing anything.

 

haha ya I get it. I can only have one "not ready" to get through emission so to choose I flip a coin between EGR and VTCS
