are there any advantages in mounting a radiator at a different angle other than vertical?can you increase air flow?

Andrew.

allegedly it can actually be better to have a slight angle because more of the airflow hits the fins directly rather than rishing straight through. I don't think it would increase the actual flow, though. Something like this:

Apparently 20 degrees is the optimum angle for max cooling efficiency

Yup. Slight angle works well... Presumably you'ld also want the fan at a slight angle to the radiator though for the same reasoning!!

I think if you're trying to wring the last drops of cooling out of a radiator setup ducting is more important.... and making sure there's a way out for the air post radiator- this is often overlooked, resulting in a super hot engine bay and poor air flow through the radiator with the open nose cone acting like a big air brake

good point chris

I always tend to look at what companys like caterham do,they spend thousands of pounds in developement for me
Looks about 20 degree's to me

Thats a nice bit of work in that picture, you do get what you pay for.

any progress with the turbo paul?

Will you be ready for a blat at York in the summer?


Andrew

Yes hopefully I will be at the MK York drag meet again this year,I sure Chris Mason is looking at getting another one sorted for this summer,last years meet was such a great day,one of the highlights of the year for me

but!! if thats right why don't the manufacturers just make them with the fins at a 20degree angle to start with, all the cars i've ever owned have had the radiator vertical.
