New UCW project

[Petr Brezina]

First test fit today.
Old cooler out, new cooler in You can see the difference.

[Adam Bech]

Wow! Well done. How it works? Better efficiency? What kind of muffers you have installed in your Carrier?

[Petr Brezina]

Yes Adam, bigger is always better
There are some custom made inox mufflers from the previous owner. Ugly, but will last forever

well done Petr, great to see it being used and lived off ! Being a Mk3 you don't have the luxury of the additional airflow being scooped in from the duct behind your head ala all previous Mk's I am guessing they thought it didn't make a difference, or the radiators in the mk3's were perhaps much larger / efficient.

your mufflers being drilled, good move, I also drilled the edge of the can at its lowest point (if that makes sense) so water couldn't sit in the cans.

nice use of the ratchet strap for the track bashing. Lynn is correct in what he is saying with regards to best practice to break the track at the sprocket, however, I have also had success breaking the track like you did.

quick tip (unless you know this already) when putting the track back together remember to loosen the front idlers so they slide to their rear most positions, it helps a bit, plus you have all the adjustment again when it comes to re tension.

I have no doubt you did this, but thought I would chime in anyway.


its never stopped me before !

Cheers

Richard, the scooping effect at 7 mph is not that great, however the possibility that the carriers were being slowed down by excessive drag was seen as justification for deleting the scoop. Carriers were not the base design for Bluebird (a small plug for another great Kiwi)
Getting away from the heifer dust, (and FYI) the MkIIIw does have a slightly larger hole in the div plate, I assume, to compensate. I found this out when I used a MkI U.C. blanking board for a pattern, and cut a second one for my AOP MkIIIw, which then fell through the hole.

I think that all this is mainly about the airflow.
On the older Marks there were relatively big intakes, but small or badly placed "exhausts", which caused that hot air couldn't escape fast enough.
I believe that evolution of the air ducts and engine covers on Mk.IIIs should fix that. They removed air ducts, but added a massive grill to the rear. With the slightly bigger intake hole in the divisional plate it should guarantee the optimal airflow through the engine compartment.
Coolers and all the rest remains the same.

Petr, my AOP at serial 84xxx (which is much earlier than your MKIII) still has the two holes in the rear lower hull. It then had a bolted on duct that took the air flow to vertical up through the rear deck via a chimney with a closeable baffle.
I'm not sure how it was used- I guess it was to keep the snow out, at which time the total air flow exited via the rear vented engine cover.
