I'm having some pieces cut out on the waterjet/CNC to build a plenum with a volume of around 5 liters.. It'll have 90* 2" aluminum elbows welded to a 1/2" aluminum flange, which will bolt to the stock lower portion of the intake manifold. The face plate will have a 1/4" radiused entry into each runner, cut out on the CNC. That will give us a nice/smooth transition into each runner, versus a 90* edge. The TB opening will be cut for a Q45 throttle body. Anyway.. Here's a scan from the autocad program..



If testing goes well, I will probably build a few more..

Hmm, cant wait..

 

Wow i wonder how much you could sell these for...?

 

oh wow...if i'm looking at this correctly...it looks like a casket

i remember SSR engineering made a coffin like IM for their rwd vq35de

 

Are you in Tucson yet?

 

This is way different than SSR's manifold... They had a box that mounted to the lower portion of the plenum. It had WAY too little plenum volume and runner length. This is actually designed more like the Kinetix manifold, except with the correct plenum volume, and radiused entries into the runners..

Not yet... still stuck here in humid/hot Louisiana..

 

From what I have read, so far the best VQ35 intake design had a plenum volume of 7 liters, velocity stacks protruding about 3 inches inside so they're roughly in the middle of the plenum, and a triangular shape for the lower part of the chamber. They claimed something like 20whp over the 350z intake but I've never seen any actual proof or dynos of this.

Isn't the FWD manifold 5 liters in volume too?

 

Not sure.. This one is exactly 5.6 liters in displacement. It should be plenty adequate for a FI application. N/A and FI intake manifold design can vary greatly.. It's all experimental.. If it needs more plenum volume, we have plenty of room to expand.

What ever happened with this??

 

My machine guy has been a little slow, lately... Here's a few pics of the pieces that I picked up this week/last week..

Just waiting for my aluminum 90 degree elbows to show up, and I can get this thing TIG'd up..

Oh, also.. that's not the correct orientation of the TB.. the throttle cable will actually be facing down.. and hidden under the plenum.

Now thats what I'm talking about. Keep us in the loop.

Thanks,

Will this fit a 6th gen Maxima?

 

Maybe.. I'll let you know when I've completed the fitment and testing...

 

You will have to get rid of the EGR.
