To Make things simple?????
O.K. Einstein, If it takes a chickin in a half a day in a half to lay an egg in a half how long does it take a rooster settin on a doorknob to hatch out a hardware store????? I need to Know cuz we got eggs to fry!!!!!


Sorry (no offence intended) but you lost me somewhere around the word simple and the smart @$$ in me couldn't resist. *[smilie=non_banana1.gif]

Bug, *IF everything was perfect and you always ran at wide open, then maybe you wouldn't need it. *I keep the thermostat in, otherwise I'd run too cool. *Being in the desert I decided to have the most cooling I could possibly get, without extreme expense. *I have a 2 seater and am pretty much just in the sand, however we will go out for some trail riding in the summer to get that speed fix. *I now get the best of both worlds, I never come close to overheating and with the thermostat I always run where Honda intended the engine to run. *I don't know my exact temps, it is in analog gauge from the '95CBR900RR that is graduated in zones.

In the picture is a radiator from a small block Chevy. *The inlet is in the upper right, so I biased the fan there to get the most out of it. *The fan is 10" for size reference. *Many changes to the mounting have taken place since the picture was taken, but it is still the same radiator and fan.

Phil, *Sorry if I lost you with the math, but I really dislike when someone give a "thechnical" explantion with no background or support. *I did keep it very simple, and only pointed out the main governing equation in an attempt to show why changing different varaibles in your cooling system has the affects they do. *Thanks for the compliment, however I can only imagine the mind of Einstein.

Thanks, I like when someone shows there background as well...The difference i see is that yuor rad is about 6 times the size of mone, lol....I am not posative i will have a cooling issue yet, I have read suzuki motors rn hot, nature of the beast, I have yet to see 220 degrees were most are running....Time will tell if i have problems, hopefully by the weekend ill be able to put it to a true test....

*Hi Mike, *No apoligy nessessary, I understood what you said and it makes perfect sense although I am ignorant to the technical terms and equasions you were using. I am a 46 year old high school grad with no further education so alot of the formulas and calculations used in advanced math and physics don't mean much to me as I've never worked with them. The same explination you gave but in laymans terms would have been easier for me to comprehend the first time through. I have found that there are alot of people like me that are more than capable of understanding very techincal things but because of a lack in education it is very easy to talk over our ability to understand. Thats why I think it's good to add laymens terms in with technical terms so we can all get it. *I am in complete agreement with your oppinion about backing up what you say with facts and/or proof. The old "do it my way because it's right and I said so" has never flown very far with me either. I have met way to many like that and have found that they usually know less on the subject than I do. One of my favorite things is meeting people smarter than me as I usually learn something new or even get my oppinion changed on somthing old.
*
* The bottom line is my previous post had nothing to do with your explination. I just got a thought in my brain that I thought was funny and *posted it. It's not uncommen for others to have a different oppinion than mine when it comes to my humor. The wife and kids are always telling me to shut up. So if the Einstein thing was out of line I'm sorry.

The amount of air that can flow through the radiator when vertical is less than what will flow through an open hole of the same size. The tubes and fins reduce the actual area the air can flow through. When you tilt the radiator at an angle, the frontal area decreases, but up to a point not less than what can actually flow through the radiator. I believe yours is beyond that point, but just as a guess. Adding shrouds would increase the frontal area. I would leave the fan as a push complimenting the convection of air rising through the radiator and air movement from moving. I assume the top of the radiator is the end that is forward.

Yes the hoses hook on top, the cap and bleeders are at the ut most highest point....I dont think i am going to have a problem, i was seeing 205 the other day, I was told gsxr can run 220 safely....
