1641 Turbo EFI Manx. 250Hp/337Nm Turbotub

Lee,

I did not make the new fan setup. Its just a picture off google.
The boxing in the fans seems logic!

I will see how the fan mount i made performs and will adjust if necessary.

Panel, i got the fans off ebay. They are "spal" fans.
They move 342cfm a piece.

Not much progress this week.

My alloy and stainless steel will be in on monday.

I hope to make lots of progress next week.

Hi,

I got my alloy and stainless in today, looks like i need another 90° alloy bend short.
But i can start routing my pipes.

Going to pick up a pipe cutter from a friend tomorrow so i can make straight cuts on my alloy.

I will start with the centrepiece between the end-castings.
Looks like i will have dent it to fit under the dynamo.

What is a good gap between the end-castings and centrepiece?
I think 2mm?

"... Looks like i will have dent it to fit under the dynamo. …"

rubenski, if this were structural I would say no, I wouldn't advise it. Since it isn't the only thing I can say is that by denting the tube you might affect the air flow some... just how much I don't know or if it would make that much of a difference.

I think I posted that there could be some airflow advantages to an oval cross-section or using an oval tube with round ends to fit what you are hooking to… something that might be interesting to look up at some other time.

No real advice but just some things to think about.

You might be able to grind a little off the bottom of the dynamo stand if you look at it.
That is why I made mine 1 5/8ths diameter. It matched the stock style endpieces and it also made the couplers the same size so they would slide over the intake centerpiece when installing or removing. If the centerpiece is larger diameter then you can't move the coupler out of the way to get anything apart easily.
If going 2 inch you can clearance and pound some dents into the cross over tee. Leave a 1/4 to 1/2 inch clearance in length to be able to tip it into place.....it's going to be tight.

Yess, i know its tight. But i also dont think that a little dent will be an issue.

Not so hard to get off, just take the left endpiece off and slide the centre piece out... I

Not that easy if you have the heater ducts on your fan shroud.
You can’t take the intake off without pulling the fan shroud off.
I can’t pull my fanshroud off without pulling the body.

I plan to get a fanhouse without the heater outlets.

Just dent it. Airflow won't be hurt enough to notice anything, just dont crush it. Not like any of our setups are absolutely optimised in any way. Most of the choices we make while fabricating are based on fit rather than absolute performance.

So true, So true!

When life gives you lemobs, dent 'em!!!

All finished denting!


I had to use the selfie cam on my cellphone. The back one is toast...

Been working on how I want to route everything after the turbo outlet.

So my intercooler outlets are both on the left side. (Standing behind the car)

One is near the buggy shell and the out is at the back.



The turbo outlet will be in the centre of the IC. After the turbo, a 90° to the left and then a 180° upright to the IC inlet near the buggy shell.

Out the other outlet of the IC another 90° down at a slight angle pointing towards the engine.
The plan then is to feed the TB wich is laying flat at the same hight of the centre tube.
Taking pics is difficult when I'm alone in the garage and holding 2 pipes..

I will stare at that for a day or 2 before I make more cuts in my alloy pipe.

Ordered 1 meter of silicone hose so i can connect stuff a bit better. Using tape now but its a pita if you want to make small adjustments in allignment. Hope to get it tomorrow.

Oh, btw, the BOV, i know before the TB. But after the intercooler or before the intercooler?

Do you want to blow out hot air or cooled air?
