Hey guys there are no threads about making the intake manifold more efficient? Well actually there is only 1. from rebelautoworx. They were looking into getting the blower ported and the intake manifold, since the M62 makes soo much heat and is basically efficent up to 7psi or so because of the manifold sucking major ass. My question is: is there anybody out there able to port an intake manifold or any site outthere with an aftermarket intake manifold. This would most likely drop IATs alot so it may be worth getting before a heat exchanger... lets get some info

 

I run a shop where we do alot of port work, and I recently ported my S/C and Intake. It definitly made a noticeable difference. The Intake has a lot of rough casting areas that can be smooted out which help lower iats alot.

 

PM sent
Anybody with any more info

 

Ummm... how about waiting patiently like everyone else...
I'll have a how to in a few weeks.

On the difficulty scale... I'll call it a 7/10
On the no-brainer scale... it's a 2/10


Edit:
Also, I'm working with a local company on getting a few new intake manifolds made up for production... should be pretty minty...
One being an FMIC capable manifold... and after that hopefully a more free flowing water to air manifold.

new custom intake manifold.... sounds good to me.. add me to the list

 

ive been waiting.... for 2 years...... just like everyone else...... im sick of waiting, i have thaught of porting the intake manifold as well.....

 

As I told rockkrawler in a PM... this project is more about time than money...
I've got a lot of other projects on the go, plus my build up...

I'll keep everyone up to date when things really start rolling in a few weeks.

 

well how much money we talking here? lol I've got someone that'll charge 85 bucks plus shipping to do a port on the intake manifold. wont the work for a fmic outweigh the benefits?? im not trying to be a dick, i just don't wanna blow my wad of cash i don't have...
im sorry for rambaling.. i've been on the computer for like uh around 6 hrs straight just looking **** up and uhh gained nothing from it..

 

Well... I know for a fact that the $85 won't get the real important part of the manifold ported.
I spent $50 on welding alone, plus about 4 hours on the milling machine, and another 3 hours with the dremel.

Yes, the FMIC idea might not be feasible for most guys on an M62, but when the big flow number of the TVS start rolling... you don't want to be caught with that restriction in the OEM IM.

 

who is doing this? i am interested for doing this?

 

to who me or omega?

 

What part?

I'm doing a how to on porting the IM in a few weeks....
I'm also co-designing the FMIC capable manifold, as well as beginning to design a bigger water to air IM.

 

lol he prolly was pertaining to you nobody gives a damn about me

 

personally i would like to see a new one in production but if it doesnt work out i would want someone to port it

youz think I'll need a new tune for the porting of the intake manifold?

 

I'm not really sure..... but if the flow data I've seen is correct, it would be a good idea.

 

If the intake manifold is ported to allow air to pass around the laminova cores, then wouldn't the cooling ability be reduced?

 

Hey Omega, since we're both working on basically the same things, let me know how I can help.

 

hmm.. i guess i'll just hafta wait till i get around to getting a wideband to end up porting... depending on how long it takes for you to get a how to going i may just wait

 

No.... unless you take off too much material.
Opcon recommends a 15mm width for all laminova ports. The OEM manifold is 15mm in the middle, but tapers off to about 11mm at the ends.
After doing some research, I found that you can maximize air flow, while keeping cooling area at a maximum if the slot is increases to 22-24mm.
Anything over 24mm is too much, and you loose effective cooling area.

Sure thing!

 

Very, very interrested in this, as I don't see how "a $85,- porting job" will address the restrictive Laminova path inside. (And an extrude hone will not help much and besides that it is simply impossible because of the Laminova chambers...)

Will your new watercooled version use Laminova's or a plate type heat exchanger?

Oh wait, there was more to read (Sorry, I should just be patient):
Good to see that you investigated the Laminova slots inside. Looked into this myself but scratched my head how to widen and smooth these without cutting and welding...

 

Very good chance that I'll use the laminova's again, as they have 3 times more surface area than a conventional HE.... but if the costs from Opcon get too high, I'll probably get a hold of another retailer of high density HE bricks (same as what the ZR-1 uses), and try to work with those.

 

Yes, the Laminova surface area is huge, but we also need some airflow THROUGH the intercooler to avoid a big pressure difference...
