Cooling, would this work?
Turbo Mini Forums

Hi all,
Would it be possible to add behind the grille a mpi radiator in series to my actual minispares aluminium 2 core ? Flow wise, could I make thermostat housing to top of mpi then bottom of mpi to top of minispares then bottom to water pump?

Fitting an MPI rad in anything but an MPI Mini is a pig. The alternator, dizzy, oil filter and bonnet catch will all foul.

I have plumbed in a 125cc scooter rad which I would say helps.

How big is the scooter rad ? Idealy i' d like to find something that fit behind the grille and could help the cooling. Haven't plumbed the turbo water cooling yet so I think it will be even hotter with it ...

How did you plumbed yours ?

Mine is far from standard as I have dry deck and electric water pump.

But if you plumb it in inline with the heater it should work fine.

It's about 300mm x 150mm at a guess.

Do you know which scooter model it came from ?
I don't have the heater matrix but did drilled the take off in the head for turbo cooling so I' probably plumb it between the head and turbo.
Thanks

I think it was a suziki 125cc scooter. That's all I remember. It came with a small electric spal fan.

Why isn’t the Minispares 2 core keeping it cool enough? It should easily keep temps in check.

I’d be looking at getting the rad sealed to the inner wing better or adding an auxiliary fan.

In the 13's at last!.. Just

It can be very hot where I live... the auxiliary fan maybe the best option as last time it spit coolant from the rad was stucked in trafic. Was just a bit scared at how fast the temperature rise on boost but that is probably normal as long as it stops where it should !
What is the optimum temp for a turbo mini ?

Sealing the fan to the wing is also a good idea as the gap is large at the moment. I'm using the plastic 11 blades fan as I couldn't fit the export metal one with the timing cover breather. Is the metal one really more efficient?
