Wasn't really posting for the 80 series kit to be honest.
They had some big ass radiators and different sized pumps to circulate your coolant that may help additional cooling for you intercooler? I guess if you could cool more coolant you would have a more efficient system...

That is for an 1HD-FT, they don't list one for a 1HD-T, not sure how many have been sold but not a lot posted info out there for diesel turbo, heaps for petrol engines.
Be interested to see what they use for the core in the heat exchanger. One kick arse sized radiator and why they only used 1 fan looks like there is room for a second.
How did you come to the conclusion they where not impressive, expensive yes.
Elementary watson.
Thanks for the informative reply, you have enlighten us all with such concise detail.
I would think for that kind of money you would get more data than just hp ratings. Im guessing one look at the size of the rad and you know it will perform just like all the other systems out there.
Ack I didnt see the 80 series specific one. The radiator is bigger than most, but the most impressive part is the price!
Already posted this in the "Official" thread but this was the one I actually wanted to put it in so I'll just double up...
I finally got around to throwing in a second radiator. If you recall, I had tested my intercooler core at about 75% effective, and the same for the 12x12x2" radiator. Put together the system was about 56%. Not overly impressive.
I had a second radiator from the old Denco system that I finally added in series with the bigger one. No fan on the little one at the moment. It measures about 9x9x1" but earlier testing had put it at about 75% effective as well. The math suggested that in a perfect world the two radiators and the core should add up to about 70% effective for the entire system.
So this past weekend I did my first trip up the Coquihalla with the new setup (also featuring my new intake plenum and improved intake path from turbo all the way to the head). Low and behold, all those book learnin's, often criticized by those who lack them, are actually worth something!
My real world testing is done at full heat soak - several minutes of sustained full boost, full load, pushing 1200F the whole way, temperatures are all stable including the water.
Boost @ intake manifold: 22psi
Pre-IC temp: 135C
Post-IC temp: 52C
Ambient Air: 15C
Water temp (post rad): 40C
System Effectiveness: 69%
Theory is cool. Backing it up with results is satisfying.
And for those who like interesting things as much as I do, I have a little more to add. Since I located my post-IC thermocouple downstream of my water/methanol nozzle in my new plenum I was able to see the results of turning the water/meth on and off during the test.
Adding the juice reduced the post-IC temp in the above test to 32C. When considered as part of the whole system that brings the effectiveness up to 86%. Not too shabby!
Now I have a new problem, though. The max EGT I was able to achieve was 1200F and most of the time I couldn't even get quite that high. On the big hill out of Hope right before Hwy 3 splits off I could only get 1100F in top gear holding just below the downshift point.
I'll have to add a bit more fuel so I can hit 1300 under maximum everything again. IC is a Frozenboost Type 10.
No pics of the two radiators but you can use your imagination. They have fins and stuff.
Excellent data thanks for posting Adam.
That was at 110km/h in 4th (top) gear, auto transmission, 35" rubber - according to a calculator I just used it should be about 2000rpm. I was going to guess slightly higher.
I'll get more data this weekend when the wife isn't in the truck with me and I can spend more time with a pen and paper while bombing along.
Adam,
Any ideas on how you could increase your efficiency?
Increase the amount of water in your system?
Larger pump?

Better radiator.
My limitation is based on the water temperature when I'm heat soaked. More water in the system would delay the onset of heat soak but, equally, it then takes longer to cool the water down once the load is removed.
I don't really care about an extra 10% effectiveness in the city. My system works just fine there. It's when I've had the system loaded up for 10 minutes or more and still have another 10 minutes to go before I get to the top of the hill...that's when I'd benefit most from colder water.
