Radiators

[Scotty-Boy]

Was thinking about changing my standard rad over for a lighter ali one.

Then started to wonder if it will need such a large radiator at all?

Sure the Ultima one is undoubtedly required for an SBC, but for an 07 RS4 engine? Worried it might actually 'over-cool' with all those rows and copper.

Anyone have any opinions?

is the rad out of teh rs4 vs the ultima.
are you going to up the power of thers4 engine or track the car at all, if so the rs4 rad might be to small.

Cooling is marginal on the SBC anyhow so I would get an alloy one made to the same dimensions... the std one weighs a ton so you should loose over 20kgs doing it as well.

I do know Wayne had one made for his car but my alloy rads which are larger but with half the cores (which were from pace) cost me under £300 each so I guess they should be around £400 to get made?

A problem with reducing the weight at the front end is the potential to increase the amount of understeer these cars are already prone to.

It will also move the centre of gravity further back - Porche 911 comes to mind!!

Good point... well made!

I had Rad Tec manufacture my alloy radiator. The people know there cooling!
