Default Cooling Fans

Afternoon Gents

Life's a lesson as they say.

So I was going to purchase a welded and balanced fan for an engine I am building but have found out they are only for twin port (thicker Fan) housings.

Does anyone know the actual thickness of the different fans so I can compare please...

P/N 113 119 031A is the earlier SP fan with a width of 32mm.

P/N 113 119 031B is the later TP fan with a width of 35mm.

If you are building a single port motor I assume you are on a stock crank.

Stock (VW made) fans are good at stock and slightly higher engine speeds so no need for welded fans.

Aftermarket fans might lose a blade or two - can't comment.

You only really need a welded fan when your RPM is way above stock - by which stage your stock crank will be flexing like a brown banana anyway.

Just an assumption........

this is where you tell me that you have counter weighted your 1200 crank and you have super turbocharged a 1200 at 14:1 CR and have valve lift which you could drop marbles through........

No the confusion was that I'm building a twin-port unit but I am using a fan housing, non doghouse/heater pipes but just looking back through the paperwork it's classed as a 'single port' although fitting perfectly to a twin port......not realising that there are different thickness fans it just rung alarm bells......
