aircooled WBX 2546ccm

[aircooledWBX]

Hi Folks,
i want to show you my 2.6 Typ5 Project. My goal is a powerfull street-engine for more or less everyday life.

I want to use:
-New 103mm AA Typ4 pistons and cylinders (modified)
-New 76,4mm Vw crank
-lightened and polished Vw piston-rods
-New Limbach heads with 42mm and 37mm valves
-Cam (German 328°, 11.8mm lift) and lifters (56g) by Jürgen Nowak (don't own them yet)
-Titanium springretainers
-Straight cut cam-gears (Steel)
-lightened flywheel (3kg)
-EFI --> Megasquirt

Exhaust and fan: don't know yet

Here are some pics:

I'm looking forward to your opinions and advice !

Greets from Germany,

nice work and a cool project!

have u kept the stock WBX pattern and made new pattern on the heads??
did the heads come undrilled then?

[ruffbiker]

limbach heads come in wbx headstud pattern as standard

[fastback]

nice
where cani find more info on these heads??

thx

exactly !

where cani find more info on these heads??

Limbach is a german producer of aircraft engines, based on Typ1/Wbx.
They are very close to Type1 Heads. Double ignition is applicable, maybe i wanna use it.

I polished the Case, so the heat stays in
instead of warming up the engine bay. Polished surfaces emit much less heat than rough ones !
Of course it looks great too !
The next thing i'll do, is to work on the inside of the case, to minimize the loss of power
caused by the airflow. In German we call it "Pumpverluste".

thats a new one on me!!

I found that in google:

I don't know if it works, but its a try !

[Unkl Ian]

Why do you want the heat to stay in the case ?
Won't that increase oil temperatures ?

[aircooledWBX]

You're right, but if the oil cooler is big enough that shouldn't be a problem.
The colder intake air is, the more power you get !
I noticed, that my 1678ccm with 40 Drla ran best in cold, dry weather !

You quoted the wrong person

[buildabiggerboxer]

apologies wally, i see that now, i cant emagine how your name came to be in there. i will investigate further, very strange...

[Wally]

Don't worry too much about it BBB

BTT!
Now that I think of it, the wbx-air heads that Gerd Weiser has/had, were Sauer(&Sohn?) heads, not Limbach.

Not much usefull info, but I am back on topic
