I'll take a shot at this for dave (though he probably has other reason's) His Custom manifolds are made out of steel, this is due to, after extensive search's, not being able to find good quailty aluminum mandrel bends. So in his case it is for corrosion resistance as well as heat resistance as aluminum disapates heat naturally much better then steel. Personally I will run a reat shield as well as coating when I go to his manifolds in my winter buildup. :wink:

Dave, why coat the intake manifold? Wouldn't a heatshield between exhaust and intake manifold be as effective and less expensive? Perhpas not for the lazy.

Andrew

A heatshield the stock manifolds is plenty adequete, but there is just no reasonable way make a heatshield fit with my tubular manifolds. I am header wrapping the exhaust manifolds along with the ceramic coating. You can actually grab one of the runners with your bare hand while its running and not burn yourself. I reccomend ceramic coating the intake to help fight heatsink that much more, and of course get you style points

Wll lets see em...

Or send me some pics and I wont share.

I will be sharing these dont worry

The head flanges are one week away today(or so the laser cutter tells me, pray its true!) Than give me a couple days and the weekend to get some pics. I should have taken some pictures of the othermanifolds I made :roll: I cant wait to pop off a few more

Well Im in line....

Dave,

Yes, I'd certainly be interested in your exhaust manifolds for IDI TDs. So you also have plans for a nice flowing intake to work with this setup? That would be sweet. So if the turbo sits straight out from the exhaust ports ( not up or down as dictated by the factory manifold ) it would clear the shift linkage ( in a MKI ) and allow for a properly radiused intake tract? Will require downpipe mods for those already committed, but I suppose you'll have that too?
Maybe you should create a finance portion of Passenger Performance so I can afford all the goodies you offer...

Thanks, Derek

Guess I should update everyone, I got a few laser cut flanges, and lets just say I am going for better quality. The new flanges will be cut on a CNC mill and will be port matched. The added flow I will get from these new flanges will be worth the wait. The intake manifold head flange will incorporate the intake ports 60degree angle for maximum flow. Unfortunately the flanges are approx. 4 weeks away :cry: So its still gonna be a while, which sucks because I have so many people asking for tubular manifolds!

Next week I will have the end caps for the intake plenums comming in so I will get some plenums fabricated and post some pictures. If I have time I will try and fab up some collectors for the exhaust manifolds as well.

The 2 different exhaust manifolds will fit a1-a4 chassis and engines, its the downpipes that will vary from chassis to chassis. So I will need someone to volunteer their mk1 and mk4 for those.

Financing... I already have my plate full so it looks like it overtime for you :lol: Once I get a few of these suckers made I'm sure you'll find ways to come up with the cash, I will make them as affordable as I can, but I will not sacrafice quality for cost. You won't be seeing any log style manifolds here

Nice update, I'm looking forward to results

zagarus · « **Reply #23 on:** September 18, 2006, 07:36:21 pm »

hmmm, so should i just wait for one of thses manifolds before i go ahead and drill a hole for my EGT sensor into my stock manifold? so i take it we're looking at better air flow, lower EGTs, better spool up time, mo power!

935racer · « **Reply #24 on:** September 18, 2006, 07:48:27 pm »

The more power and boost you want to run the more necessary it is to upgrade your manifolds!

Kudagra · « **Reply #25 on:** September 18, 2006, 10:03:26 pm »

I want ONE MIEEEELION pounds of boost!

Here is a ghetto draft of the exhaust flange on solid works, I plan to have the flanges done in 3d on saturday. You can see a little bit how the port goes from the stock oval shape to a round shape to match the primaries.

And I got the machinest to do some test pieces for me so I could see his work. Seems all is well, here are some of the T3 style turbine inlet flanges I got him to cut, and drill/tap.

dave,
don't know if this is the right place to post, but if you're having a bunch done up, put me on the manifold list....no rush as you know, but I'll pick up whenever they're ready (also, let me know when you have an intercooler for mock up )

RabbitJockey · « **Reply #28 on:** September 25, 2006, 10:04:42 pm »

i'm kinda curious what's up with making manifolds, they already are available for the gassers, and, they will obviously work on our cars...

Your machinest must have a 5 axis mill. The transition from round to oval will be tricky to machine without one. I suppose it could be picked out with a ball mill on 3 axis equipment but it would cost alot, machine time = money. I'd be tempted to squish the tubes a bit to get the transition, the result would be smoother and the machining WAY easier. Better clearance from the intake as well.
