Just a question on fans. I checked the two spare fans that I have and they are slightly different, the vanes on one of the fans are longer. So the question is are there different versions of fans for 126's?
I remembered Chris's question as I spent well over an hour trawling through every known web site trying to see if the high density plastic fan I am now using is still available anywhere. No luck but I think that it was on the Axel Gerst site that 3 fans are shown , Standard , Alloy & a Superior Fan that had those extended vanes, said to be balenced and about twice the price of the Standard.
While I was thinking about it I just checked the fan belt drive on my car & the engine pulley is about 6" diameter & about 4" at the dynamo so by my reconning if you hit 6,000 rpm then you are going to be pushing that dynamo & fan at about 9,000 rpm
Smallcox told me he has tried a very short run with the fan belt off & noticed a major increase in power. Might be alright for a standing quarter mile but do not try it out around town
