Smitty,

Appreciate any info you can provide.

I have a printer, but I’m not sure the surface finish would be ideal for airflow. My intention was either aluminum or Delrin, but seeing what they are selling for on eBay, I can’t even buy the material for one. They seem to be fairly sought after. Would there be a market if someone were to make a few?

At $10-$15 off ebay, I wouldn't even look at my material supplier catalog.

Rookie,

I agree. When I initially asked Smitty about sending me one, I didn’t realize they were so inexpensive. They must be a blow molded piece….?

​​​​​​​That said, since they seem to be sought after, would they be marketable at a higher price if they are no longer available for $20?

Thanks. Brad.

I doubt theres any real market for this piece since manufacturer quit making them, I just stumbled onto fact on flow bench/dyno that it took a modded tb from 1200 cfm to 1500+ and a 650 hp engine with nothing on tb to 685 hp in back to back testing. BTW, to answer your question the other day, I watched the scanner on the whippled 8.1 when it was on my dyno yesterday and at 8 lbs of boost it was commanding 23 degrees of timing so im sure 24 would be fine too tuned rich,Smitty

I ordered in one of these intakes to.evaluate and test with, pretty impressive, definitely "big"https://cimg3.ibsrv.net/gimg/www.off...5f39b942ae.jpg

nice :cool-smiley-026:

to much for a 454? LOL

What I'm not sure about is that if I have a larger intake port than a larger head port, the CSA will be driven by the port inside the head.
On the other hand, I don't know how bad the port mismatch can be. I've read several post on forums that in carburetor versions, the rect intake with oval heads didn't lose performance.:confused:

There is some support for a 0.050" smaller int port. It promotes fuel atomization with the shear.

I wouldn't do it.

A rec port intake feeding an oval port head would be a disaster.

Thats a really good question that i DONT have definitive answer for. I can say this, I used a 2000 cfm throttle body on my street car, a 11.4-1 pontiac 461 with mefi4 ecm. I made roughly 580/590 hp on dyno and similar tq, it made 95% power at like 5/8 throttle too. I was able to tune any bog out of it with AE so even a really fast stab does NOT cause it to bog, it comes alive instantly. I was having a discussion about this intake and since the whole ports NOT big, IDK what it will really do on something its not appropriate for like a mild 509. It has a 5.31 CSA at entry and tapers / funnels down to a somewhat normal bbc opening , I wouldnt put it on a 454 unless it was gonna turn some serious rpms, like 7500/8000 BUT it WOULD be interesting to see what it does on like a stock 500 efi. Since a stock 500 efi is as cam restricted as intake restricted my guess would be it would give up 30/40 ft lbs tq sub 3000, 20-30 ft lbs tq 3000 to 4500 then gain 20/30 hp on top and 200 rpms based on shorter runner length and other intake experiments Ive done BUT you really DONT know until I pull lever on the dyno. Im gonna cast a mold of one of the ports to map/ measure size of csa top to bottom

The mismatch it's a disaster....
:throw:
