waterboxer radiator location.
 

Good night Guys,

Other than putting the radiator up front could it be placed in another location outside the vehicle ( engine going into a beetle ).

I think the way Wally placed his intercooler would also be a really nice way to place a radiator.

He's gonna hate it that I use his car to promote watercooling! :lmao::););)

I think it looks pretty good, and it fits the German look.

Here is an unusual location:

^^^ That's really nice!:)

I think that will work very good. A shaft driven fan should provide more then enough cooling air (after all, the aircooled engines use the same construction).

One thing to watch out for is balancing the fan, so it will not shatter at higher rpm's .

well don't really like the positions shown there.

Well, then you are out of options! :lmao:

Put it in the front.:D

Behind the rear wheels using small radiator(s) and wider wings.

A pair of Mini rads (not BMW) venting into the space above the gearbox and ducted from the leading edge of the rear wing. The inlet hole doesn't have to be that large and probably no more than 1/3 of the rad size.

Great minds my friend... Guess who has already sized them up ;)

I've got a pair I bought for my Ghia and they'll work beautifully (I hope).

Someone post a photo of these radiators please. I had an idea to build a 5 pass 12 x 13 x 5 inch radiator.

That's very small. Where are you going to place it, and what kind of fan are you going to use with that?

I think another member on this forum used a small radiator to cool his waterboxer engine and that was placed in the rear fender area.

Why do people always try and reinvent the wheel?

All the ducting in the world is not going to make a rad in the parcel tray area work properly, the only way is something like Wallys.

Front is still the best option though, look at all factory setups that are rear or mid mount (Porsche, MR2, MGF just to name a few), they still use rads in the front, cos it gets the best air flow and the heat can get away as well.

The wheel has been re-invented many times because there is always room for improvement!:lmao:

For example, the Fiat 850 used a radiator mounted in the engine bay next to the engine! It had a really interesting fan / scoop arrangement. Have a look.

Yes, but the fast Abarth version of the 600 (same engine I think) eventually had the radiator up front.

No HP loss on the fan anymore, and better weight distribution.

But it will probably work nicely, a shaft driven fan.

Give a dog a bone here!

I was just saying that there are more than one way to skin a cat. Right how you just hold the tail and let me have at it!:lmao:

GL Volkswagens aren't fast like those cool old cars:D

By the way, how do you put pics in there without the silly links I use?

Lol, sorry DORIGTT! :)

You've got to surround your image with these img tags:

I'll step back now... :o ;)

2.5 wasserboxer
 

http://i254.photobucket.com/albums/h...6.jpg~original Here's my racing Okrasa wasser being redied for fire up after a rebuild and detune.... It was turbocharged with staged 8 injector system back in the mid '80, my cooling system wont help a road car install, but in my case it works well, it uses two Honda bike rads for L&R heads over the trans, these pair up and off up to the main rad at the front, control is electronic, no mechanical water pump is used. its on carbs short term for a shake down in a well known saloon car championship over here, before it gets its injection and ignition system back on. its built for corner exit torque and mid range power. more data to come when its looking more finished and set up, i have another build planned at 2.9 ltr, all the core is ready for machining etc, all i need is the time:lmao:
please don't fall for all the myth and rumor about unreliable wassers, its only the owners that introduce the weak links, as with any engine, ive made expensive mistakes myself:angry:... they also love turbos and have a very good head design, very det resistant, and the lower half can take prodigious power hikes as they come from stock, the coolant has better thermal efficiency than aircooled, allowing more power/ advance for longer time periods, plus all the T1 goodies can be used, from cranks to camshafts.
I Hope to see more wassers being built :beer:.
Best regards, spanners,,

:cool: love it.

Interested on your water pump removal solution - I've got an electric to fit to mine so would like to know. Did you just remove the impeller?

Al, thanks, i positioned the pump on the return side near the engine so its having it easyer than otherwise, they will work fine
with the mech' pump and belt still working, then run them on after shutdown to kill heatsink, but i was after getting the installed weight back and gaining every last h.p from reduced loads and belt drag, the impeller, shaft and bearings etc have recovered the weight. ive also machined the c/s pully and flywheel to reduce oil seal friction, and also run 100 % coolant, the difference can be felt turning by hand, i should have done a torque comparison before and after!!:rolleyes:

Cool. And the housing has just been welded up? Any cooling flow problems?

No, in my case i can pre bleed the system, with it all quiet, you can see and hear it bleeding out, all the rads are at the correct angle required to self bleed, i also use a high mounted main rad to protect the engine from any trapped air, bearing in mind time is tight at a race meet, you gotta go when they call ya!!:driving:

:) Would really love to see it. Itching to get mine ready.

I'm still set on rear mount rads. I think that the electric water pump will give some cooling benefits and I am confident that I can get enough flow through two aluminium radiators and some heavy duty fans.

Have a look in the bike world,:cool: rads and fans being far superior to car stuff regarding weight and efficiency, the only problems are adaptors etc, re' small pipe dia's on bike stuff, mine hooked up nicely with a bit of planning, also air control ducting is key, both in and out as you know.:)

Can you show us a photo of those bike radiators. I was thinking about using the Hayabusa bike radiator and tilting it 45 degrees.

Cool, I did look at some and will look again - I've hunted for some alu 3 core Mini race radiators. Look perfect and the actual rad, albeit a standard one, that I borrowed off a friend fits a treat ;)

Badbug, you can just see the l/h rad in the pic, the r/h one is in a similar position near the starter. Here's the front rad', its set high to self bleed easily, and allow some protection in the event of..... oops, it happens...plus other stuff is mounted under it, battery, oil coolers etc, the rake angle and ducting slow the air making it more efficient, it has a built in expansion tank and can be moved warward for service purposes without dismounting coolant pipes, exit air is ducted out in the low preasure area behind the front wings. regards....http://i254.photobucket.com/albums/h...5.jpg~original
