Aftermarket Exhaust Manifold

[dansedgli]

The 6boost one looks good. Is that in the factory position?

If you are asking about the one I posted its not. Its a high mount manifold for an AU. I was just showing the coating.

do you have some pics of customers cars with these manifolds on that you could put in this thread? it seems a few ppl are interested in these manifolds.

Have a look at the pictures of RIP85 for the BF set up and mine for the FG.

here are a couple more pictures of the FG Manifold.

Awesome post Kyle!

Interested to see results of your upcoming testing...

xyz does that heatshield come with it or did you make that yourself. looks really neat

also, do you find there is too much heat on the side of your rocca cover or bonnet or even the overflow?

6boost mani's are notorious for quicker spool. I was makin 340kw with the stock mani and turb at 17psi. with the high mount fitted and same deal, 15psi made 373kw. full boost hits real hard smack on 3000rpm. the guys at elite loved what the mani was doin. I love the nasty exhaust note it makes 2. had for about 2 yrs now and still looks the same as the day I bought it, and its not even heat coated !!!!!

Hey Mate,

My tuner made the heat shielding for me, it is the same material that is on the standard manifold. you can buy it in sheets from places like repco etc...

Yes the manifold does create a bit of heat, however the heat shielding we made up does a great job protecting to coil cover and overflow. Took a bit of fiddling around making up different stencils, however the end result was great and even has a factory appearance.

Hi Adrian,

To show a little respect for the administrators, I am more than happy to help with any technical enquiries about the pro's and cons of an upgraded manifold, but lets not steer this into a for sale thread

To retain the turbo in the stock position, yes it will have to be an "upside down" style manifold, due to the position of the turbo flange. If you were to build a manifold without decent merge collectors as top level manufacturers do, you could get away with something very low in orientation, however the gains would probably be negligable over the stock manifold with this configuration. I will be doing some back to back testing with a HTA3794 turbo on the stock manifold vs aftermarket manifold, as I feel to get any true indication of the real gains, you need a turbo with enough headroom to demonstrate the difference which this turbo will. I will also the compare this to a twin scroll T4 high mount manifold as the turbo's now also come with a 1.00 T4 rear. I feel this will give the best spread of testing all with the same turbo, but with 3 different manifolds to really give a clear indication of what difference each makes.

As far as heat shielding goes, they aren't supplied with the manifold however it is highly recommended. Most people think the turbo is where all the heat comes from, however the surface area of the runners is huge in comparison, and when mounted high in the bay they do put a lot of heat into the engine bay. This doesn't seem to be a problem once correctly shielded like Ben has with the ACL material.

well im happy to buy 1 aslong as the dump pipe I have now will bolt up to the turbo without any dramas.

ill pm you regarding price availabilty etc.

how does the manifold go upside and the turbo still bolt upto the original dump pipe. im confused. by the way I have a 35/40 with .7 comp cover and t04z internal I think.

[Adrian_F6]

just out of curiousity, does a high mount bring in boost earlier and reduce the boost for the same power like 1 that retains the standard position?

are high mounts the same price as the standard mount aftermarket manifold?

[mic]

high mounts are the way to go because it allows for a better flange position. very cramped and not much room with the side mount to do this. I would imagine a high mount would breathe alot easier than a side mount, therefore making easier power. but kyle will have a better answer.
