What radiator for Duratec?

[The Pikey]

Can't decide what radiator to get for my new build. The engine should be doing 260 ish bhp and I want to use a Laminova so it will also be cooling the oil in a round about sort of way. I am currently looking at the Caterham Triple pass

 

The Radtec 45mm core and also the Radtec extreme but this seems way over priced...

 

Any other suggestions?

 

thanks

Have just received a Radtec (non-Extreme) as replacement for my Caterham rad which sprung a leak, great service, very well made and will cover up to 250bhp according to Darren at Radtec.

 

They are made to order so would be worth chatting to Darren since they may be able to adjust to your needs.

Additional notes:

(not to be used on the road with race springs fitted)

 

Why not a C400 one? should be better for hoses

 

[The Pikey]

yes that is worth a thought. I'll speak to CC Tuesday to find out if there is any difference between the C400 TP rad and the normal TP rad.

 

thanks

Jason,

Let me know what CC said...I just bought a C400 one for a race car

[The Pikey]

I think you will find that the C400 rad is the same size as the triple pass but is just a standard flow radiator.

Spoked to Darren at CC and he says both the C400 and triple pass are the same cores (so both triple pass) and the only difference is the fittings.

They look the same but the c400 is not triple pass. Check the header tanks, the triple pass has welds in two places on the header face, these are not there on the C400 rad.

Caterham have done lots of testing with different radiators, which I've been involved with. A triple pass rad will restrict the flow on a Duratec engine and may cause rad to expand.

if that's true then it's the first bit of duff info Darren has ever given me ☹️ I'm sort of edging towards the R500/R300 race rad at the moment anyway as these seem good value for money at 350 quid for a combined water/oil cooler and I have been told there's a version coming that the two are separately replaceable if needed.

I have used the Radtec Extreme on my 250 hp Cosworth/Duratec 2.3, and am very pleased.

 

One advantage over the triple-pass I earlier received from CC (don't know if this has changed), is that I specifically ordered the Radtec with the upper inlet and outlet ports on their proper sides, so that the radiator hoses would not have to do crossovers to reach their proper ports.
