Yes, *figures* is sort of like the phone number code. Although, we have no prices listed on this website so, I think we can say, prices are on the website listed above! If you haven't checked out the website yet, go check outMcKinney Racing!

We just added two pictures of the intake manifold on the website!

im a little late on this post. how much are we looking at paying for this new intake?

The 3rd time mentioned this post

Look at his WEBSITE!

I looked at it every time I posted on this thread

AM91Camaro_RS

The website is back up now, or it was a second ago anyways. I think I know what the problem is, we'll get it taken care of ASAP.

V6Camaroman, we will send you a PM.

Question
Does everyone want provisions to hook up the EGR tube? This manifold is intended for off-road use (as are most aftermarket parts) and does not have any CARB certification numbers. Our prototype manifold was not built to run with the EGR but provisions can be added if people want them. So, can we see a show of hands for who wants to still run the EGR?

Also, FYI, the prototype throttle body does not have the coolant lines hooked up to the bottom of it; it is not setup up for them. However, adding that should be no problem. We have had a couple of questions about this so we just decided to put it out as common knowledge now.

Most of us probably need smog legality.

Smog legality on intake manifolds is easy moutain to climb.
YET
I never said it wasn't costly expenditure

lucky me....no egr required =) so i wont be needing it

Aggp18

i would need a legal set up, pennsylvania is a wonderful state for emmissions

Supermann

well, the coolant isn't needed in the throttle body right? I thought that was for if you lived in a particularly cold area or something. I think the egr provisions would be cool cause it is nice to make it all legal

AM91Camaro_RS

We can put the EGR hook ups on the manifold but it won't have any CARB numbers, not at this time, anyways.

The coolant on the TB is just for cooler climates. More than likely, all of the TBs will be built so that you can use the piece off of the stock unit for the coolant tubes, if you want them. If you don't want them, you won't need that plate from the stock TB.

how much would it cost for a intake plenum/throttle body with the parts for smog and coolant lines for the throttle body?

Naft

i won't be buying one without a carb # . . .

AM91Camaro_RS

As far as I know right now, there shouldn't be any price differences between the smog "legal" and ones without smog hookups...same for the coolant lines.

I am sorry for you guys that need the CARB number. From what I hear, its a very long process to get that all done. We might check into in the future, though. Also, FYI, this will be a pretty simple swap, if you want to put it back to stock when you go for smog checks...

yeah simple...its only like 40 bolts but yeah it is simple not reason you guys couldnt put it back to stock for smog checks...dont be so lazy hahaha

Ill buy one without a carb number i just want it to bolt up to the smog and coolant lines

AM91Camaro_RS

Sorry we haven't updated on anything, guys and gals. We haven't decided against building the manifolds or anything. We just have had a lot going on lately and haven't had much time to mess with them. I did talk to my welder yesterday and he is still interested in welding these up for us. So, hopefully we'll be able to release them before very much longer. Again, we appologize for not posting any updates lately.

Just throwing out some questions I'm surprised no one asked yet! Those who purchase the intake will need to port their runners right?!

Just curious how much further did you port the runners from a typical gasket match porting job?

What did you find to be the best method for porting for them? I know when I ported my runners I was concerned with keeping the port as even as possible thru the whole runner!

AM91Camaro_RS

Attached is a picture of a stock gasket and a ported gasket (stock - top). Mainly if you look near the bolt holes, you can see how its a little more squared off than stock. Its difficult to see in the picture but it is a fair amount bigger.

We plan to include a flange that will bolt on top of the stock mid section that will have a taper in the port then the new manifold will bolt on top of that. This will be a pretty "short" taper seeing as how that flange/adaptor will probably only be about 1/4" thick. We are planning this method for ease of installation and so that porting is not *required.* We will still recommend porting the mid to see peak gains.

We ported the cast aluminum mid section using a rotary file in a pnuematic die grinder. If you use some WD40 or Zep 45 or something of that nature, the bit will not clog up with the aluminum. So far, we have only ported right inside the mid section; just into the top bend. We do plan to port all the way thru, just got too excited about getting the manifold on to see what it would do!

We ran a comparison test on the flowbench today with the head bolted to the bench and the full intake bolted up. We found approx. a 5% increase in airflow from .200" lift all the way to .600" lift. Keep in mind that this is without having the whole intake port matched. Really, none of the sections are matched up like they should be. The base has been ported mildly but the lower part of the mid section has not been matched to it yet. And, the base isn't matched very well to the heads. We will plan to do more testing later as the track times would suggest more of an increase in flow than the bench showed. Also, this bench is not a top of the line bench so it might not show the best numbers.

redraif

Well please post up some bench flow numbers after the full port! I would be very curious to see what happens!

Man I would love to see what my set up bench flowed after all the porting I did to the intake and heads! Though all that will be out the window soon! Just glad I only have to clean up the heads further and not report a new set like we were initially discussing! I plan to shark fin that darn lump in the heads and see if that helps. Wish I could remove the darn thing. If it was not so much work i would love to remove the hump and see what it really does! Esp with the car's mods as far as it will be going soon!

You have an opinion on the hump in the heads intake? Your heads are ported right? What did you do to yours?

AM91Camaro_RS

Here's a pic of the port work that we just finished on our heads that are going to go on the motor. We plan to "play" with a(nother) set of spare heads we have sitting around. We are going to grind the vane clear out of one to see what it does to the flow. As of right now, I am in no position to say one way or another whether it is really necessary to have in there. All I know right now is that everyone seems to think it needs to be there... We also just picked up some nickel rod for welding cast iron. It is also machinable. Depending on how lucky we get to feeling, we might see if we can do a little welding to change some angles...

redraif

Would be absolutely be interested in teh numbers both pull. How soon you going to remove the hump in the spare set?

I think I might thin mine out at the base a bit more...shark fin it further. All accounts I have read say its needed to help keep airflow control, so just having something should do the trick I would think! Another accound said it was there cause GM made the port too big and did this to compensate...well with the mods done to the car, I would say I could use some more room!

AM91Camaro_RS

I'm not real sure when we'll get around to working on the spare heads. It should be over the summer but it all depends on how other projects go. I think that the reason for the fin being there as to do with physics more than just what the motor has done to it, though.

redraif

Physics meaning for helping to control the airflow?

AM91Camaro_RS

Not just helping to control but also just helping airflow (velocity, maybe) in general. I have read that the hump helps the air make the sharp bend that we have going to the valve.
