Martin, it is very hard for people to understand... heck, I've only tested BLOCKS and I can barely find the time. You are doing fans, rads, fittings, blocks, pumps etc, etc etc. People don't realize that it takes me about 12 hours to test one block with 5 mounts... If I make $100/hour you can see how it adds up... Manufacturers should really be PAYING people like you to independently test and validate data - of course this data would not be public but you would be PAID. This is what BillA tried to do at one time but never succeeded at it. I mean for a mfgr to pay a few hundred dollars for you to test and validate seems to be chump change.
