I am glad that you took my post the way that I intended. One way or another, whether positive or negative, I felt that relaying my experiences objectively as best that I can would help serve the community more than pointing fingers and creating unnecessary drama. I don’t have any personal grudge or stake in pointing fingers at you or discrediting your products – I’ve never met you, and I have never had any arguments with you – if you were Greg Dupree or Tom Green I would have made a similar post relaying my trials and tribulations with your product whether good or bad. Like I pointed out in the original post, I appreciate your enthusiasm for a platform that other larger companies like HKS or Stillen have long given up on and moved onto the newer more popular vehicles. I am sure you could be making a lot more money doing something else but the fact that you wear so many hats in your own company shows where your head is at – that you do this because you want to not to get filthy rich. However, as I stated in the first post, my Z just never ran right with your fan. I attempted many other band aids, such as getting a vented hood, changing to a smaller oil cooler, and performed the basic maintenance to make sure all the air was bled out of the system from the leak in the radiator hose. I eliminated all the other considerations which left me with your 3000 cfm fan pinpointed. You say that the fan was intended for the Koyo radiator and that without the shroud it will not run right. On a radiator with a much larger mounting surface than the 16” fan, I agree (such as for a stock radiator or Koyo application). My radiator’s mounting surface is a little more than 16”, so a 16” electric fan would fit it to a tee. As you can see in the pictures I posted in the original post, there really is no substantial area for the air flow created by the fan to bypass the radiator. That is why SPAL distributors told me that a shroud would not dramatically decrease the effectiveness of the fan for a radiator with such dimensions. Perhaps those are the words I should have used instead of saying “waste of time” for a 16.5” core of a radiator. However, with no other modifications performed, just by switching to a 2470 cfm SPAL fan (with no shroud) and taking off your fan, temperatures decreased to 175-195 F. When my car would be stuck in traffic and water temps would slowly increase to 195, the e-fan would then kick in and drop temps back down, to a low of 177 F. When I had your fan on my Z, when it was stuck in traffic and temperatures hit 195, I could hear the fan kick in but temperatures still hovered around 195 or at times it slowly kept increasing to the 215-220 range. I admit, I am no expert when it comes to radiators or electric fans and I am trying to learn about them as I go along, but if a huge part of an electric fan’s effectiveness lies within a properly made shroud, then why did simply replacing your fan with a SPAL fan, still with no shroud, that should theoretically pull even less cfm (2470 cfm) than your 3000 cfm fan result in such dramatic decrease in temperatures? I would think that a fan that claims 3000 cfm should blow away one that only pulls 2470, not even close. Also, on the box of my SPAL fan is a disclaimer; it states that the 3000 cfm fan doesn’t have a sealed motor, and that it absolutely should not be used in areas with dust, rain, dirt, or high ambient temperatures, and that it shouldn’t be used for continuous periods of operation at a time. You say that you never your fan is not a SPAL unit or never claimed it was. Is your model so different from how SPAL makes their 3000 cfm fan in such a slim package that it is fit for a daily driver and is so durable that you have proclaimed it a success? I don’t have a great memory, but did you market the fans as being only for race use? I dont recall them as such. 
Once again, I think this discussion will help everyone in the community who has or has been thinking about an electric fan or your double pass radiator kit. Thanks for keeping it professional and not making it personal.
got me a bottle
