It's all good, no worries. I can't wait for it to be welded up and then we can get the ball rolling on the recirculation tank. I still have a few things to do... All with steel line... gahhhh.

Went to a local hydraulics shop and had them flare this out for me: Here's a Mock Up:

Welding should be done today around 5 or so.

I are furious! I installed the mount and radiator then while I was driving home a hose slipped off an adapter and dumped all my coolant on the road in front of my apartment. Pulled it into a parking spot, turned it off (clouds of coolant all over the place), opened the hood and see the entire engine bay sprayed in coolant.

Here's what it originally looked like before the coolant spraying everywhere:

so the line was made by the shop or you did it and the shop flared for the B-nut? im curious cause i want to venture into some hard line stuff as its cheaper than all rubber/teflon AN's by about half even after getting the tools. and was wondering how it is to work with for bending fitting?

I bent, they flared. Not a bad gig honestly. I'm hoping for much more compact attachments.

I'll get pictures posted up tomorrow sometime with the new setup (fan, and mounting scheme)

Made that mounting scheme for the fan in 4.5 hours just in time to go drag racing. Now i'm looking forward to constructing my own intake manifold, and getting a proper standalone in there.

Looks good man... you back in Culpeper yet? We've been having some fun days in the garages working on 8s...

Not yet. Mid may... I'll check my voice mail tomorrow to double check but I want to say I start May 17th.

:icon_tup:

Will be back in town around May 17th (will have some work to do on the car too; just found out i'm leaking from a pin-hole leak behind the water pump housing).


Well, it's finals here at VT so I've been kind of swamped with studying (have a final at 445 in structures, which should be fun), but in between studying for finals I've found some fun in doing some CFD analysis for my manifold design (off the shelf manifold parts available for purchase via your local google store search)

Here are two pictures: First flow is roughly NA, second flow is under pressure.

I figure it's time for an update. Consequently a lot of work has been done with research into the proper intake manifold design. Here are some of my results. As you'll no doubt notice, the flow characteristics have not improved, but in fact have decreased significantly from the original flow pattern. Have no fear though, I still have a few things up my sleeve to nail down the proper flow.

Design Iteration 2: Modified Plenum Chamber:
Low Velocity

High Velocity

Design Iteration 3: Modified Runner Inlet Angle:
Low Velocity

High Velocity

So I talked to a guy I work with that actually does CFD analysis for a living and he's informed me that the reason that the manifold doesn't work correctly at high speeds is because the intake flow is too fast. This means it might be much, much easier to solve my problem than I originally thought, and it will mean I have ability to add some nice fancy features.

That is some really cool shit T

Quick text update: I'm running more CFD and adjusting my design for the intake now. Talking with my only source for CFD understanding I have come to the conclusion the intake will be fairly transient with the current setup. I'm doing minor alterations to further correct the flow distribution to the runners, and should be close in the next few days. (I'm getting some flutter--not large--between the primary runners)

Here's a movie (or 2). The first video is actually the progression of the latter video (the latest design iteration). I need just a little more work to even out the flow on the number 3 and 4 runners (you'll see what I mean), but it's coming together a lot more quickly now.
