Company called Performance Manifolds in Australia have developed a inlet manifold that adds 25rwhp for the V6.

This is without any other mods!

They also have a V6 with this Manifold, headwork, cams that puts out 421hp at the flywheel.

Two hours, four spanners, an extra 25hp at the wheels

Look them up

I called them about a month ago and the prices well lets just say are out of sight.

What kind of $$ are we talking about? :driving:

First they do not sell the intake. From what little information I got they sell through a exhaust / muffler distributor. I can not remember the name, but it took them a week to get the price and the cam information.

The price was over $2,000.00 without shipment and the cam information seemed to be secret. I even went as far as to see if GM performance had the cam grinds only to find out they did not exist.

Nice! Thanks for the info... Sounds kind of shaddy. :slap:

Last i read was that the manifolds are around $2000 AUD.

Cams grinds if custom made in house would always be secret, why would they just give them out? Like you said that their is no cam grinds available...

Just imagine doing the intake, cam, and headwork than installing a supercharger that someone mentioned in another post a month or so ago. That would be one bad ass V-6 sleeper.

It would be much easier to take the existing manifold and have it ported and polished on a flow bench.

Cams will not be secret for long.

IMHO this group is all about the money.

You are not going to gain anywhere near 25+hp from your stock V6 manifold. You would be lucky to get 10hp out of it.

2k for a custom manifold that adds 25+hp is not as bad as you think. Custom Hogan's and Wilson manifolds are not cheap and they sell like hot cakes.

That manifold plus cams and then a single turbo at 6ps would be a bad ass V6..........

I believe that Performance Manifolds gets the full 25 HP gain. Hogan's and Wilson are hand made (very nice) pure racing intakes. Between boost and cubic inches I would just choose a certified used GXP LS3 @ 415 HP.

if you read the website carefully it is 25 hp on an otherwise tuned motor...
