Would you be interested in an intake manifold?
Hey,
I'm toying with the idea of producing some custom hand built parts as a hobby and have noticed that everybody wants a nice short runner intake manifold for the VQ but nobody makes a good one specifically for the FWD chassis.
I'd like to know if there would be a market for this. If I sold 5-10 I'd call it a successful adventure, if I sold 1 or 2 it wouldn't be worth it to me since I don't even own a Maxima right now. I'd be most interested in the VQ35 since it is the most current version.
So, who would be seriously interested in laying down several hundred dollars (3-500$ probably) for a short runner, all aluminum intake manifold that put the throttle body in the stock location?
I'd need a volunteer to do some careful before and after dyno testing and work with me on some critical dimensions, etc.
thanks,
allen

Just saw the post about the Kinetix manifold, what a coincidence, I didn't even know they were making one. I'll wait and see what the dyno says on their product and their retail price. I'm sure my design would match theirs atleast in terms of power, actually I'm sure I could beat them on price too.

Even if you can't beat em in terms of gains (which I'm sure you could do as well or better) you'll definitely beat em in price because it seems that they have their branding and some of the "bling" factor taken into account there.
Regardless, keep us posted because I'd definitely be interested in your IMs as well.

Depends on the interest, if I had a few people who could prove their interest by putting a certain percentage down to help cover the cost of materials then I could get started on it right away.
Bottom line, if I had a few definately "sold" then things would progress quickly, I don't see it taking longer than a few weeks if all went well.

I'm interested, but i have a vq30, so does that count? how far is joplin, MO from stl? i went to undergrad in stl and wouldn't mind making trips down from chicago when i have time this summer if you need a vq30 test mule.

For now at least this will be for VQ35's only. If this goes well I could change the design easily enough for the VQ30 people, all I'd have to change would be the flange.

if it is under the kinetix price and show the same gains people will get it.
if you need 100 to start i'll deposit that amount. but first you have to find the test car and as soon as you get everything straight i give 100 down for the manifold.

I'd need it tested on a 3.5 though first.

Alright, I've got one deposit confirmed by PM, if I get 2 more we may be in business.
As far as the dimensions go I can get that here at work from cars we have. I'll definatly need a tester though to do some accurate before and after dyno tests w/ no bull and no other changes to the car like exhaust, different dyno, etc.
If you want to confirm a deposit PM me. Once I get atleast 3 and a confirmed tester that I can trust I'll feel good about it and we can go from there.

PM recieved, that makes 3 confirmed deposits but I still need someone trustworthy who's been around the .org for a while who will volunteer for the testing. Anybody?
Also, we need to discuss some things regarding cosmetics. Does anybody care if the stock engine cover remains? I don't want to design around it honestly, I'd much rather not have to worry about that. I think most 4th gen 3.5 swappers won't care but not sure about the 5th and 6th gen'ers.
And, I need to know what throttle body to design for, the old cable type or the new drive by wire type? Maybe it can be drilled for both.

I know u already touched on this ...but once the 3.5 ones sre done and tested u would be willing to mindidy ur design to accomodate 3.0s...right...since our TB and Lower IM are different....is there anythign special in the BOX portion of the mainfold or is it wide open...or does it have runners for each cylinder hidden in there

Modifying this design for a 3.0 would be easy enough, if the 3.5's go well I'll definatley be looking into that.

I will chime in on the other stuff though: I don't really care for the stock cover, so won't matter to me. I have DBW, so I'd have to vote for that too.

Here's a couple links to pics of some general ideas I have:

i was also thinking bringing the TB from teh side like sotck and tappering a the main plenum box down kind of like Supra and Skyline aftermarket manifold....jsut to eliminate the bent around behind the maniold....and going strait in....i am gonna go some drawings in inventor when i get home form work and ill send them to you

cool design but is it going to be even flow?

as far as dual TB i dont think the gains if any would be worth tha hassle ...now Individual throttle bodies per cyline like an RB26dett now that would be sometign to think about...but again thats alot more research and development and that will further increase cost

thanks
looks very promising. material? sheet metal? aluminum?
#37
...yea the angle of the plenum is more for forcing air to the far end of the plenum...if u look at aftermaket supra and skyline sheet metal manifolds its a similar design ....i have it as aluminum....but its really upto Allen22 when he decides to do it what he wants to used....both would be fine..but aluminum would be lighter obviously....i am gonna tweak it some more tonite and hopefullt get some hard dimensions and do some flow calcs
