Too expensive for me but i think you're talking about the Harrop intake manifold that is made "down under" for the HSV's. Cool looking intake and has two 52mm tb's and looks like an old school intake. I know a couple people were interested in getting it for older hotrods for kinda a vintage look.



Click the pic to go to the website of Harrop Engineering where those are made.

Hope this helps,
William

Also just saw you can get it with 55mm tb's as well and the price looks to be VERY high. Not sure if i'm doing the conversion right but it looks like it's over 4k!!!

I believe that is right cause there were threads about this manifold. It isn't worth the money IMO.

yea if i had cash to burn i'd get it because it's sick looking however the gains cant be good enough to warrant a 4-5k price tag.

you guys do realize that intake doesn't have just 2 throttle bodies, it has 8, one for each cylinder.

Yeah, 2 52mm throttle bodies would be less than impressive for 3k.

A = 2 x (pi x radius x radius) = 17,000 mm squared

FAST 90

A = 25,450 mm squared

How big are the 8 throttle bodies anyways? If they are all 52mm, then that would be 68,000 mm squared total area....that's a crap load.

Yea i realize it has butterfly's in the intake it's similar setup to the FR500 intake for the ford guys. They weren't claiming those at "tb's" though so i just said the two 52 or 55's they claim. Looks interesting but waste of cash with the intakes that are out.
