Staying as close to “six” form as possible, I tried to emulate the
heat flapper valves on the sixes. Took a page out of @mepstein technique.
I’ve never seen one for sale for quite a while, so a bit of diy.
Basically a hole saw cut in the mushroom cap.
I’m a bit pissed as the craftsman arbor refused to stay clamped
tightly and we had a wobble on the one cap. (IMG:style_emoticons/default/headbang.gif) So we don’t want to look at that one too closely. (IMG:style_emoticons/default/barf.gif)
Ran to Lowe’s and picked up a new Lenox arbor and 32mm hole saw.
A lick of paint later. We are ready for heat.


Can you tell me more about the difference between the caps? Have been saving a pair of NOS 914-4 flapper valves I used for a few years on my car before converting it to six cylinders. Is the hole there because the 914-6 makes too much heat?

One of the worst things about my 914-4 SSIs with the new heater flappers was too much heat (even without the blower up top) and heat bleed on hot days.

Thanks!

Rhodguy/Kevin was selling a six flapper box. I figured Porsche did it for a reason so I just copied it. I just used some regular 4 pieces, cut out the hole with a hole saw in a drill press and then blasted and powdercoated the parts. Mine weren’t in great shape so I had nothing to loose.

First one is Kevin’s original.
2nd is my modded one.
3rd pic is a comparison from Rory.

Just a wild guess, but I'm thinking the cooling fan on a six moves more air and can apply more pressure on those valves so Porsche added the holes to prevent blow-by and the heat bleed you mention.

The drone of a 3.2 with a sport muffler is numbing. 2000/2800 rpms. I’m considering a single outlet or convertible muffler like yours Mark.

Have Ben modify yours. Or sell it. They get good money on pelican
@914dave

That might be an option.

Or you can cap one end for highway driving.

Small update to chassis repair. A strip of steel added to the area where the floor meets
the outer Lt. long. It took some coaxing to put that bend in! Was surprised in all honesty! It does not run the whole length because Dave said to hold off because we will need to tie in a couple other pieces. The piece on the buck is not done yet, so
just a small patch for now. I used a piece of an outer long to line up where the outer edge should lie. Levels & straight edge where very important here. I’ll trim off the
excess later.
Wanted to make sure there was plenty of real estate to weld the out halves to.

Nice work! (IMG:style_emoticons/default/welder.gif) It's causing flashbacks though (IMG:style_emoticons/default/evilgrin.gif) I did the same thing leaving the weld flanges wide and I think it is a good idea. It is easy to trim those back to flush with the outer clam shell flanges for perfect alignment.
