Thanks for the kudos, good to know I'm helping. I'll never get around to writing a book, but I figure that thanks to the Internet I'll be able to share a lot of what I've learned over the years with future VW fanatics even when I'm dead & buried. I've force-fed my son VW trivia since he was 5 (he's 23 now) and he's retained a respectable amount, hopefully he'll be able to take on the responsibility of filling in the gaps when I finally succumb to Alzheimer's ;)
I had an afterthought about your cooling-system question...long ago it was thought by most (myself included) that removing the stock cooler from a SP and replacing it with an externally-mounted tube & fin unit would be an upgrade - turns out that when you do that you end up with wasted air flow to the base of the LH cylinders and an overall INCREASE in engine operating temperature. The doghouse fan housing has internal vanes which even out the distribution of cooling air...if you were to take one of those and skin off the doghouse, and patch over the slot that feeds air to it, an external cooler could be used to advantage. You could still use the narrow SP fan with this setup, too, so the doghouse shroud would be the only stock part you'd need to hunt down. --- asad ishaque <[EMAIL PROTECTED]> wrote: > > Marc! > > Im convinced not to go ahead or plan such a > conversion.
