Did locate an alternative stainless sheet metal plenum ... Polder 216204 should fit better in the V but might transfer too much heat.... again not plug and play.

I think the Polder 210201-30 will be faster.

as they always say Greg.... Ignorance is Bliss! enjoy your little corner with blindfolds on.

you too Sean!

you guys are SO juvenile:bigbye:!

I am! :)

Looks great and built for speed my friend!! :)

Ha, Ha just a play on the red is faster but I still prefer the more stock look of polished metal..

i made mine as dirty as you would want, aside from "fine" tuning.. i think 335rwhp off a 5 liter was respectable. thats 320 going to about 400 with only removing smog stuff and making it run a little fatter and less restrictive. so we agree here too.
however, there is more to go with the intake and you know it. Im not talkng makinig a balloon out of tin foil and calling it an intake, but a little thought or bastardizing something that actualy is in production might be a good bet.

after all if anderson and fan can put that stuff on their engine and have it give 100hp with no tuning, there is room for more, dont you think, over the stock intake ON a 5 liter. again, when i talk, i could care less about anything under 4000rpm, post shift 4500rpm and redlining near 6600rpm.
that narrow window opens lots of options

At least my bread will be crispy. :p

Okay, time to tame the bearded lady and the midgets in this circus....

With regard to sheet metal intakes, still not a bad idea. :)

I googled some images to use as samples.

Below is an S2000 sheet metal. Take note of the tapered runners again.

And another great picture cutaway of tapering.

Diameter is important according to the book I am reading. The bottom taper must match the diameter of the cylinder head's intake port. Common sense of course. However, We run into diameter size at the velocity stack, or mouth. Objective of course is to funnel as much air in and at as fast of a velocity as we can (tapering helps this too), and with as long of a runner as required for the engine to exhibit gains in torque and power. This mathematical formula is what needs to be solved in order to get the desired length of runner.

Again, pointing to Greg's intake, his curved runners egressing from the large plenum have the perfect length to yield these gains. They appear to be significantly longer than the factory setup. As for diameter? Well that's Greg's secret and I am sure that he would have to kill you after telling you.

those look good!

I'm pain free too, and yet it still has perfect continuity :) I'm really enjoying Jims thinking 'outside the box' to arrive at affordable and practical solutions. Keep up that lateral thinking :thumbup:

Often wondered where the term " it is toast " came from when referring to a blown up engine but I think I am seeing the connection. It is not like someone sent me a letter explaining it....
Been looking at vuvuzelas as a low cost velocity stack option... the solution is out there !!

I dont need to get credit for anything here, but I'm glad our interactions and information started to get folks thinking.. regardless if sean or greg knew what i was saying, its all discussion and talk. i dont know why they have to act like 3rd graders and be so proud to push someone out of their "group". real mature. It's ok, Jim and i still banter back and forth and i suspect things i say get him thinking, as seen by his responses.
the bottom line, im here to learn or find new ways to improve on the 928 platform.

Just a thought, I wonder what Todd's manifold would do without the turbos pumping through it ?

It strikes me as the kind of thing I'd be looking at if I were building a NA manifold.

Hacker ?

Your arrogance has no limit, does it?

Todd's intake is not a "bolt on" endeavor to a stock 928. If he ever takes his engine apart again, and I think I can sneak that intake away for a weekend......one could jimmy rig something just for a dyno test.
It won't be petty and the hood won't close, but it could be done.

Not that I've given this any thought or anything...... :icon107:
