Sorry no measurements at hand. Here's a few bad pics, sorry for cluttering your thread Bruce!





A bit hidden pic of the upper A-arm and shock mount of the front

Shoot I also meant to Oooh and ahhhh over your sexy new pump. What do those things run, if i may be so bold? How did you calculate what you needed?

V2Rocket

well f*ck me...that is awesome.

just the other day i was pondering if the rear suspension of a 2006 subaru could be adapted to a 944...looked somewhat feasible. very basic design they have (3 pivot bars and a Mac strut), but very cool still and fairly lightweight...

No ooohs and ahhhs necessary. Thank you though.

I didn't have to calculate at all. It's designed / made specifically for this Motor by Gary Armstrong at ARE. Fantastic person to deal with - when you can get him to stop moving.. Just the pump and pulleys you see here are $1,650. The crank pulley and belt and dampener are another $600. Then there's the Pan, and Dry sump tank, fittings and plumbing. I think the whole kit would be close to $3500, but I have most or all of the other necessary parts at much cheaper cost.



No need to apologize! I was going to ask for pics of the same thing! lol

very very nice build

Think outside of box is always fun

odurandina

wow.

amazing what you guys are doing with your cars.

OH... I thought this was the, Winter Project thread for a second. This is the V8 build thread.. ok.. Nothing on this front for a little while. Much on the car has to get done first.

95ONE

Since the chassis is mostly done, it's time to revisit this Thread.

I started back with the custom header.
I'm going to run stepped. Sorta. The ports off the chamber will run straight with the head port angle, not the flange angle and might be as small as 1 5/8". The collectors will be top notch with runners connecting in firing order to attempt a swirl and will neck down and back out.

10-12-13
Most of the car is done and the paint is finally finished. I have some more red accents to make, but I got the car completely painted before the Paint booth got torn down. Shop is closing this month.
Now that that is done, I can move back to the motor part of the project since the car is ready to receive it. I will start with the Engine Mounts and Headers;

The engine mounts I made were solid. I decided against it and rebuilt them to include an Isolator bushing and clear the dry sump pump, steering rack, and Leave lots of room for the header. That part took a long time. But, in a rare moment, I will leave all that explaining out and just post some pics of the final result.

1 5/8" is the size of the ports even though they are "D" shaped, so I made some 1 3/4" tubes into smaller D shapes on one side and kept the full "O" on the other. This mates the head side of the flange and port to the full tubular size of the Header. It took me quite a while to weld in all the excess space. The Header flange Kit I have is a Full "O" port and is way too big for the "D" shape, so after I made the adapter tubes, I tacked in the tubes and filled in the gaps. I then did a quick port and clean up job to keep things tidy. There is still a small amount of mis match, but It will have to stay since I don't think I will be able to bolt it up the exact same way every time. The bolt hole tolerances and fitment will be too random. So I left a little more room rather than less. I will leave the header flanges like this until the motor is in the car. I can then tack up the rest of the header at that time. At this point I get a stepped up header with hopes of scavenging. And hopefully it keeps the exhaust velocity at it's highest.

Next is the driveshaft pilot bearing adapter to fit the Porsche input shaft, a Canton Dry sump Oil pan, Clutch set up and release bearing alignment, 153 tooth starter adapter.

Always interesting to see what you´re up to. Nice work, impressed with your energy and know-how!

The big deal with header design at the port, is that the floor of the exhaust port is maintained into the primary. That's where there's power to be had.

The port has to maintain its laminar flow around the bend. Any steps or gaps screw that up and flow is reduced.

Also... you need to radius the pipe where it meets the port so that you have a smooth continuous radius (without sharp cheater angles) out of the port and gradually downward .

That's probably more important than the collector shape.

If you do it right, get the proper shape primaries and merge collector... you'll maybe see another 10-15RWHP over what you get from the Renegade Headers (out our power levels)

TonyG

PS> That's why I didn't bother with spending another $2k on high end custom built headers.... :-)

Thanks! This part of the project should have the most work over the next month.


EXACTLY. I am trying to achieve that exact thing, but getting the header to bolt in the exact spot where the bottom radius connects perfectly will prove to be difficult at best. Very difficult. 2 more days of work would have to be done to get the bottom radius perfect. I'm not sure If I'm committed to that right now. Finishing the project is priority and the work I have done so far is better than 98% of any Header out there. The collector will be a Burns "STYLE" and will do the system justice.

- What I know and you guys don't (yet) is that I double checked my combustion chamber size and it is cut out to a 4.1 bore!!!!! I just bitched out my head porter. I want to throw up. We discussed boring it out for a future date, and he took that as it needed to happen now. So flow is already all screwed up. I'm pretty sick about it and just want to throw these heads through his window. This is why the intake port is so much bigger than I asked for. He thought that IS WHAT I ASKED FOR. So these heads will Rock on any 383 cubic inch motor or larger. I don't doubt it. Unfortunately they are just going to HURT my current size, and cost me power. Sure, they'll be a little better than LS6 heads, which is still a strong combo. Just not the $3K worth of Heads I paid for. .. ... ... .. sigh. $2200 would have gotten me a fantastic set of Trick Flow heads proven to make 500whp on this combo. After all I've been through and learned, I STILL did it wrong. And I knew better.

The plan is to just get her together and running. I'll polish and perfect the Header later. maybe. I just want to drive the damn thing. So damn bad.

I'm sure many of you know exactly what I am saying.

TonyG

Just get a set of core LS6 heads and my head shop will run them through their CNC machine for $600 and be done with it.

And their program must be decent because the LS6 is making 461RWHP/400RWTQ on pump gas.

Just a thought....

BTW... I meant to say DAMN!

Someone else beat me to the rear GT3 in a 944 suspension setup!

Nice job BTW!

Now that I've slept, and credit due to Tony's prodding, - I've decided that I could do a little better in this direction. (with minimal work) Not perfection, but as good as it's going to get. I dimpled up the bottom of the ports to better match the short radius.

I also finished the last custom part of the drive train to make it all do the Porsche/Chevy dance. It's the pilot bearing adapter. Good thing the 944 bearing is smaller. That made this possible. This was my second attempt and took very tiny cuts around both diameters to make sure there was JUST the smallest amount of interference fit. It took quite a while to make this little guy.

Now I can install the clutch and move on to the hydraulic slave cylinder shimming. I had to make a special engine stand that lets me have clear access to the flywheel. I'll post a pic of that too.

Here are some pics.
