BEC radiators

Hi Guys,

1st post in the BEC section as I'm using a Pinto in my Indy.

Does anybody use bike radiators in their BEC cars?

Cheers

Nick

Yes, for example see here. I am using the R1 rad in my BEC too. Nice and light, and if you have an R1, it has the right number of inputs and outputs (not just IN and OUT).

Most don't as the airflow is not normally adequate.

Most go for Micra or Polo. The micra also has a thermostat built into the rad for fan switching.

Fitted micra rad with a high flow Spal fan





If you're not living life on the edge you're taking up too much room.

Bike radiators are fine if you site them well and get good airflow with them. As a matter of fact the airflow in a seven is as good or better than in the bike (no fairing forks and frame to distrub airflow etc).

My R1 has never been above 95 degrees even when being thrashed on a hot trackday. Only problem will be sitting in queues, you just need to wire a manual or temp sensitive switch to bring on the fan.

Car rads are potentially better (just because the are big) but are overkill for most applications other than racing.

And apparently car rads can be worse than the bike rad when the number of inlets and outlets is more complex than just IN and OUT - ie. fusing the various flows into one pipe can be problematic. This is why I went bike rad on my R1.

cheers for the info guys!

Next question is do you think a bike rad would be enough to keep a 2L Pinto cool?

I would imagine it wouldn't be sufficient. I'm even surprised at progers' coments about using the R1 rad in his car.
In my (and other club members' experience, the engines do so much more work in a car than in the bike that the original rad just cant cope. Nothing to do with the frontal exposure or airflow. BUT, it obviously works OK for him.
I would just choose a rad similar in capacity to the original Pinto one. Just my 2d.





The pay isn't very good , but the work's hard.

the R1 rad worked fine in my car the only time it got realy hot was at traffic lights or a traffic jam but the fan kicked in and out and was never a problem.
I dont think the R1 rad is bigger anough to cool your 2L tho
