This weeks cooling system test summary

As many of you know I have been working to develop a better cooling system for the TI engine. It is based on the original design from the late Joe Locicero. At the same time I have incorporated extensive tests for 13 other systems.

Last week I prozed that my shroud needs more work before it can be sold. I was able to test 2 different other systems and will finish up by Wednesday of this week with the rest of the testing.

Here is a summary of my findings this week, more to follow.

Jake: I realize that this is difficult but it is really necessary to know the input power of each fan as well. One system may cool better but takes more power and at the same power may not cool as well. A 50 hp fan is bound to cool better than a 25hp fan.

Each system is getting tested @ 6,000 RPM pulling the fan belt, and then @ 6,000 RPM without the belt....

I have ALL the bases covered!

Jake,
You, without a doubt, definitely do!

hey speedytub any blems/prototypes available?

hi all,
i understand the need for testing/comparisons but what is being
checked, hp draw, lowest possible cyl. head temp?
and not to forget the performance/drivability loss till/if your
engine reaches normal operating temp.
the one thing that can't be dyno tested is "looks"
personally i would go for the 911 fan (on looks alone),
practically speaking the stock doghouse setup with operating
thermostat works great.
how much time does your engine spend at 6000rpm?

jake----i just read stf pages-wow you've been busy, you're a
very determined person. do you ever take a vacation?

Hey Jake.
This is David in Long Beach. That is some great information on the fan testing. We are a lucky group to have you as part of this club. You get to do the type of mechanical testing all of us only wish we were equipped to do. Stay with it, I'm sure a breakthrough is just around the corner.
I find your work inspiring and interesting.

I could care about looks less than anything else... Looks don't keep my reputation where it needs to be, or my engines cool!

The fact of it is that too many people are concerned with looks alone, and let that sell things for them. If you are in it for the long haul, usually even a big busted, beautiful Blonde isn't the best choice- even in women.....

I consider the 911 system to be the "Dumb Blonde" of all systems, good for one night, but then toss her away for a brunette that can cook and clean and wash your underwear without bitching! I'm out to PROVE it all, and hopefully I won't be eating my words about the 911. if the stock shroud beats the 911- I'm throwing one bad ass party!

I could build a generic 911 cooling system and sell it for a huge profit. Hell it has just one mold, not 4 like my shrouds do. It also just has one casting instead of 3... They just don't cut it for me, thats why I'm not even offering one till I do get a correctly designed system TESTED and proven.

When I do my tests I do runs at 3500 RPM and 4800 RPM with loads at 10 lb/ft and 14 lb/ft. Then data is logged every 2.5 minutes. At the end of each test a power run is accomplished at 6,000 RPM and at 3500 RPM both and without the fan belt. Data is logged on spreadhseets and then analyzed so we can create a summary when we are done.

This is VERY hard work and VERY expensive. To date I have spent over 5K bucks on the test engine, fuel, time water (50,000 gallons so far) etc.... BUT IT HAS to be done!! I spent over 6,500 on the TIV testing alone- atleast its an R&D tax write off.

when i test we are going for the best temperatures, and most even from side to side.. Most aftermarket systems cool 1-2 cylinders extremely well, but 3-4 really poorly.

I just added these graphs to my forumare posted here... more will come later and then a big summary when I'm done...
