Cooling Question

[fast70]

I have a '68 Beetle that has a turboed 2110 and am looking for some ways to cool it. I have a tranny that has a 3.88 R&P and .82 4th. My engine builder thinks that I will be under revving it and it will build up heat due to reduced fan speed.

So, I had the idea that since Jake did tests that show that the 911 fans work better when there is not quite as much air trying to be forced through it, it would be a happy medium. Instead of using the hole drilling method that he used, would my reduced RPM from the transmission along with a good fan ratio be enough to get it to that point of good cooling.

I would really like to use a 911 fan because I have one and it would also free up a lot more room for the turbo setup. But, if it is going to destroy my engine if I use one then I won't.

Thanks for your help,
