Hi, all havent been here in ages... 931's still in peices... you know how it goes....
But i have a 951 Im trying to get done first, funny thing is in a way I think I would like driving the 931 better.

Anyway, So was last working on equal length headers for the 931, placing the turbo where the AC compressor was (plumbing around the front of the motor)
However the turbo could be placed in the stock location if wanted.

Well So heres the deal, I made a mock up, did fitting etc, in mild steel and just tacking it, since I wasnt up to full welding.

anyway, Id like to find some one who would be interested in helping finish the project, and obviously youd get to copy this design, and make your own.

heres a few pics

what I mean is, I send them to whoever and they can complete/finalize the project, and make it so they are able to duplicate them.

looks great.

I had the same id on placement.

Project over here was also on a pause because my 944 engine blew up ....

Bulldog that pic is pretty sick looking..Are you worried what a ya shop will charge.. I know where to go cause like I said im gone. Ya know not in the great state of Colorado my birth place, " Aaah the scent of the wild grasses and fresh air mixed in the wind."

You did a crazy job on those headers.

How do you guys plan on draining oil from your turbo with it so low? Seems as though it would be extremely close to being below the oil pan oil level.

thnx,

i'm more afraid of the fact it is possible thad it can't be bend out of one tube per runner (3D bending) than the price it will cost me...

You don't whana know how many $$$ the intake has and will still cost me .

But it looks like MikeDanger his runners are re makable

Interested. PM me with details of your proposition.

PostPosted: Tue Mar 15, 2011 9:43 am    Post subject: 931 Manifold Concept Reply with quote

I've been looking at MikeDanger's header mock up and have a few reservations (not to throw cold water on the project). I think he's done some decent work there... but there is always difficulties involved in turning a piece built out of mild steel elbows & straights into 1 piece exhaust runners. Our company does lots of mandrel bending for the heavy equipment and automotive industry.

-It looks like some of the bends are a bit tight. There is definitely a minimum bend radius to bending due to material flow.
-It looks like some of the straight lengths are a little short. There needs to be enough straight length between the bends so that the clamp jaws can grab the tube to pull the next bend. Special jaws can be machined but that ups the cost significantly.
-Keeping radius measurement uniform should be a design goal. You have to reset the bender setup to change the bend radius. Mandrel benders don't like increasing or decreasing radius bends.
-Limited run, intricate bend projects get expensive quick.

I would like to hear, though, what it sounds like if he gets back to you.

Cheers, Brian

Why are you guys so concerned that the runners are mandrel bent from one single piece? Seems superfluous for our engines.

First let me say my comments above certainly weren't meant to denigrate all the thought, time, and skill that Mr. Danger put into this concept, it looks great. I think it is a very worthwhile project. To get to an end product you have to start somewhere and this is a good start.

Point taken, there sure is the option of making the runners in segments, though I'm not quite sure what you mean by single piece runners being superfluous. For one off or limited run projects a segmented construction might be the best solution. I guess I was looking at it from a production run viewpoint where we are always looking for ways to take individual operational steps out... more operations, more time, more money.

I do think that it would be preferable to use one piece runners but obviously there are numerous factors yet to be determined that will affect the ultimate end design.

Keep up the dialogue.

Cheers, Brian

I wonder why more people don't use a simple tubular header and copy the 951 solution.
