hahaha spot on mate!!! i got some inline fans aswell for the ducting but didnt know whether or not this was OTT

I think they maybe alittle ott but belt and braces approach is good.

Got a link to them? i saw some on USA ebay about £20 a throw

Wab i did not see any water plumbing in your car at ADI?

pipes run underneath the car, not plumbed up at the front yet, im still making my airbox to sit infront of the rad, basicly same design as yours but mine is abs plastic, i had taken the rad out before ADI, where are you taking your air feed from? side windows are prob easiest as you can get the clear naca ducts for poly carb windows, my side vents where quite easy to do, only time will tell how effective they are

Then you need to think up how your going to cool your rad

I turned my water pump in a lathe to make a neater job of removing the impellers, i then removed the thermostat. You need to keep the outer ring as this is the sealing face. Then the pipe work travels basically reverse of the OEM system.

Some people i spoke to kept the water pump impellers so hey ho on that one?

My Ecu controls the fans so there is no problem there, i have a speed controler unit for the water pump this is a dial knob with a box of tricks. I would like to have it mapped into the ECU i will have to see what Master Repo can come up with?

the electric ones pumped opposite direction

depends which way you install the pump, it will pump which ever wy you want it to

I started with mine in boot, then put it back in the front!
Grind the vanes off the engine pump as I seem to remember the electric ones pumped opposite direction
Keep the pump going after engine off otherwise heat soak from engine will pressurise header tank ( like mine did)
I needed boot space too so no big deal, plus it holds water now and keeps cool enough with 2 fans

you need to run a small diameter pipe from the top of your rad to the expansion bottle, prob as well to run a small one from your thermostat housing aswell as these are the areas most likely to be air locked, also makes bleeding a lot easier

can leave the thermostat in but drill a small hole through it like 6mm dia, then test it so see how it behaves, ive had a few audis with the thermostat stuck open and fuel consumption is ***** and they never really get up to temperature. i have an electric water pump wired up to my vems rad fan output, and the rear fans are contolled by a normal thermostatic switch with a manual overide. i had one of those davis craig thermostatic contollers but they dont seem to be great so never bothered fitting it

i've seen a different one as the aux pump flows coolant in the opposite direction?

[terrybullwon]

any progress updates on this?

Well its done.

But from speaking to atleast 6 different people there are many ways to do it.
