I cant wait to check this manifold out.

 

Glad to see your project is coming along. Can't wait to see prototype information. This will be extremely beneficial for us guys running smaller pulley's on the M62 or TVS plans...

 

The TMAP in it's original location will only measure cilinder 1 in your new design, correct?
Best location should be somewhere in the mutual airflow of all cilinders, so just after the cooler...

For good flow this bypass channel is exactly in the wrong spot. Off course the routing can be changed with some angles and tube, but still.. Was also looking in the flow direction of the SC outlet. We want this to flow more to cilinder 4, so what if the complete SC is slided a little to the driver side? Then maybe the bypass also clears. Only problem... The pulley.. This should then be offset the equal amount in the other direction.. But this means extra load (Belt force x distance) on the bearings...

Thinking out loud on this... If the runners were angled a little to the passenger side. This way you can achieve the same effect without the pulley problem... (a bit hard to explain here.)
But then maybe there are clearing issues with the alternator???

 

Well... I'm planning to shift the manifold over about .75" to the passenger side to accommodate the blower a few things, as well as move the major flow are to the center of the pre-core plenum. As far as the runners, I'm trying to keep them as straight as possible. Hopefully by moving the whole manifold over, it should save us some grief.
Also, the addition of flow directors in and out of the cores should keep the flow as even as possible.

The T-MAP will probably be located on the bottom of the manifold, in the post-core plenum, so it can read the average pressure and temperature of the air (i will have to check with my contact at Bosch to see if this is a good idea).

 

That is a very common position for such a TMAP sensor. Should be ok as it will measure the average of all cilinders.
(Also, when positioned in a "fast moving air channel" like a runner, it will read a lower pressure just due to the airspeed...)

Keep up the good work and show us that the M62 is not that bad.

 

Speedy / Omega:

I just got home from work and read through both your suggestions and ideas - i had a bunch of comments to post - but it looks like you have addressed pretty much all of my concerns - and YES a flat-milled spot for Meth, nitrous, etc would kick ass!

Keep it up - this is, dare I say, MORE exciting than the TVS threads!

 

Cool...
If your spraying already... so you spray before or after the cores?

 

No, I am not spraying - BUT, I would spray Nitrous (wet shot) AFTER the cores.

I would spray METH before the throttle OR before the cores and as close to the SC outlet as possible so the meth could evaporate and mix with the air in the plenum.

 

Hmmm...
I'll look into how hard it would be to put in a face milled area on both sides of the cores.
I know the bottom won't be a problem, but the top might require an aluminum blank to be welded in to build thinkness, then milled to be at the right angle.

 

If this happens you can count me in for one as well...

 

bump

 

just waitin' on you mega'

 

Whew... I'm back from picking up my bike...
Coldest effin ride ever... ( -6*C for 3 hours... ouch!)

Anyways... I have the 3 designs finalized.
I'll be modeling the internals tomorrow, as I have the shell already modeled up.

Hopefully I can have something nailed down by late Monday, or Tuesday.

 

Sweet... after taking off my Supercharger and looking at the stock intercooler... I will DEFINITELY be getting this.

 

Posted a few pics of the stock IM in the 3rd post, 1st page.

 

I love it when people get to cut apart and gut perfectly good parts for R&D.

Thanks for the sacrifice Omega!

 

You can also count me in for one of these manifolds. I want it for my turbo build.

 

subscibed.... very interested

 

Sorry guys... I've been sick as hell for the past few days...
It might be a day or two before I have something visual...

 

Are you serious? If you are doing a Turbo Build... then SCREW that style Intake Mani. Get the Hahn IM or the Saab Intake Mani... and run an ACTUAL Intercooler.

 

No Prob, Omega.

I dont have much money right now anyways....so I can defiately afford to wait

Keep pluggin away - PM me if there is anything you think I could help you with if needed.

 

Na, that is too much for my setup and I already have a CHE and the dual pass, and it should help for less lag....and I don't plan on making like 400+ to the ground...Maybe just 350 and I will be content. The stock cooling system is more than adequite to handle this while still retaining its DD status.

 

Does anyone happen to know where I can find the GM drawing for the Ecotec intake flange?
I already have one modeled up, but I would like to have the actual specs and tolerances that GM uses, for QA reasons.
For now, it won't affect the design process... but i figured it's best to ask now, instead of waiting until the end.

 

 

Omega, let me be one of the many to thank you for this. I know I would have had a hell of a time with this one as it would be in my plans. Thanks for making a part that increases efficiency and doesn't just "add a billion hp". You are appreciate. All that said....

SUBSCRIBED FOR PICS!!!
