Anyone interested in a new custom intake for the DE motor?
The one dyno I recall is from Z1 and it was 10 whp, but of course they also sell the product. 3rd party independent dynos seem to be lacking. I wonder why?Increasing the runner diameter and using true bell mouth velocity stacks looks good. I don't know how you'll get around the tight bend at the neck - too bad there's no room for symmetry without reducing airflow... Runner airflow imbalance could be compensated for by changing the angle of the bell mouths, but you'd need to do some modeling using a MAF sensor and experiment - probably too much trouble for one off pieces.

SG already did quite a bit of volume vs. airflow vs. TB size research.

Choke points appear to be a combination of Plenum volume and TB size. Unless those two choke points are both addressed - nothing dramatic increases.

Werd.

Guys, let's not hijack this thread into a Kinetix debate.
Here's a couple of threads on the subject...

Ok correct me if I'm wrong but I see what Citris pointed out with the 2 choke points... I may be either a complete moron or I'm just pointing out the obvious but why hasn't anyone made an intake mani where the throttle body is relocated and throttle body pipe to the front of the intake many similar to the LS V8's. I've seen Vipers and Vettes that have large short piping. Idk... just a thought.
this is the idea i had for this a while back with an ls1 throttle body!

only thing is relocating the oil fill. any one done this? maybe this is somehting that OP can think of if his project is not to far along

Same would occur where as now the front cylinders struggle for air, the rear cylinders would then struggle and a spacer would have same effect for the rears instead of fronts.
You would, however, prob get air in more efficiently through less pipe and bends in intake tubing having the TB in the front of plenum (instead of forcing the air to go through more pipe and what is essentially a 180 degree turn feeding into the plenum.)
I would venture to guess maybe Nissan might not have done this because of not enough benefit realized for something like this that would throw hood clearance to chit and require a much higher hood near the front, thereby prob throwing off the outside lines to the Z. But i have no idea
I'll be using a phenolic spacer on this manifold also. Probably do a before and after dyno with that as well.
Manifold was not completed this past weekend. Things came up.

Tard noobs strike again... ugh take your advice moron.
