ive got one off ur older style ones might update to these new ones soon. is there much difference between them.

no not really just a more precise spread of flow between cylinders. since figuring that part out (still more to come though) i am concentrating on making them more uniform with less "parts to the puzzle" so its easier for the welder and easier on the eye.

cheers for that. hey r these purge welded

no just with tig and rod

do u run your sheilding gas through the chamber while tigging it up to sheild penetration?thats purging

You don't need to with alloy, usually only stainless. And most welds will be "filleted" so they will in the corner anyway, I've never seen anyone purge plenums or cooler plumbing, or intercoolers for that matter in 7 years in teh business, including some of the best names out there. 6BOOST:)

exactly, there is simply no need to

sorry boys wasnt trying to knock your product or your knowledge. i was just trying to find out more on build quality. yes it probobly was a stupid question cause of the low pressures they will contain but i have seen a plenem split open at the weld seem. just thought id ask it as im a boilermaker/pressure welder by trade so i do have some knowledge on the subject but anyways this is a great product and its build quality is second to none and cheap would highly recomend it to anyone. thanks for your time

thanks for that lowpsi. all my works is guaranteed. if you or anyone has a problem with any of my products, i fix it for free. havent had a plenum split yet (even after being sent to customer via aust post lol).

Also if anyone wants a chance to get $400 off one of these plenums, come to a Wollongong Dyno Comp. Look in the NSW section for details. Im a little far away for the Dyno comp... but i'd still like a chance to get $400 off a Plenum! Maybe I can be your 1st S.A customer and wave the flag for CPC!!!???

wyndup - pm me your car details and we will see if we can sort something out.

These plenums are top notch. I got mine about a month ago and have just ordered a fuel rail to suit. I am 100% happy with mine and every1 that see's it has nothing but good things to say about it...

how much extra rw power do these kits give?

it all depends on setup. you will notice i have never quoted hp figures for that exact reason, everyones car is different. the main reason for using a custom plenum is for the whole system to be less restricted compared to standard. having said that, there are benefits no matter what the your mods are.

PM sent mate.

Sent email about ordering plenums These are sweet lookin things man, cant wait to get my hands on one...

king-3l - email replid to.

have you a pic of the fuel rail in a car? im worried about the bend radius for the fuel hoses feeding it. can you do em with 90's or feed nipples out the bottom like std?

Here is a couple of pics for a ca18det for a customer in the UK complete with 80mm tb. Has seen 475rwhp (std stroke/crank) and is now hoping for 550rwhp. Also one of an 95% complete sr20det, just missing throttle body plate plate. This is one for the s13 (low mount inlet), but they are also available for s14 (high mount inlet). It may look like a weird angle, but sits perfectly perpendicular (90 degrees) to engine.
