Its kind of funny. I live in Alberta farm land where everybody drives a truck and someone did a similar test for our local county newspaper. Again they were really just testing "towing power" using a bobcat on a trailer and came to pretty much the same conlcusion. Of course these "reviews" do...

I hope i am not hijacking the thread too badly but I have a farily relevant question. I currently have a prodigy brake controller. I wanted to get a brakesmart but they were not available for a brief period of time last spring when I needed to buy it. I plan on getting an exhaust brake and was...

I think the same thing you think, it is just electrolysis. I looked further into this and there may be some merit to his claims. In his first application it is clear he is just using electrolysis to get hydrogen and oxygen that he then recombines in a torch head used to cut metal, simple enough...

Nice update to the website Sean! I just got back from vacation last night and was pleasantly surprised to have a UPS notice waiting for me. I picked up the IR coils and can't wait to get them installed. I can tell just by looking at them they will have a nice smooth progression curve. As to...

Ryan, we are obviously on the same page in regards to the purely thermodynamic impact of nitrogen, but get this. I phoned my local industrial gas supplier (Praxair) to inquire about the relative pricing of bottled gases and for 99. 98% pure nitrogen it was $CAN 82. 68/cylinder and for "dry" air...

Here ya go, http://www.tomorrowstechnician.com/tt/tt020532.htm It is not because the nitrogen makes it cooler because of its thermodynamic properties, but that air "aged" tires become degraded internally by moisture and oxygen and generate more heat internally in the rubber. Also air filled...

Further to my post above the constant R for CO2 IS quite a bit lower than air (R for CO2 = 35. 1) which means it would want to expand less than air for a given temperature change. The problem is that it also has a low specific heat (0. 2016) which means for a given amount of heat it changes...

Now I am honestly not trying to be a smartty pants here or make anyone look stupid but here is an image from a thermodynamics table. As someone else pointed out above air is predominantly nitrogen and as a result their thermodynamic properties are very similar. In the range of temperatures and...

I am not sure what part of Alberta you're from but here in Calgary I have had mixed results at the dealers. Actually I just posted a couple of days ago about a problem I was having with steering/brakes and I was preparing myself for a fight about my steering system which was messed up before I...

Class specifications? Does any body know or have a copy of SAEJ684 (SAE wants like $50 for a copy)? It would appear that this document outlines the specifications for the hitch classes. From what I can gather class 4 is for hitches for trailers from 5,000 to 10,000 lb. I am just wondering if...

Was driving back from a camping trip this weekend towing a light trailer (~3000 lb) and I had to stop fairly quickly, not to the floor with the brake pedal or anything like that, but fairly aggresive. When this happened the brake system made a pretty loud hissing sound (not ABS, it did not...

Get a gacket Another option is to just buy a rubber PTO gasket. The six bolt PTO cover is standard and can be picked up from any truck hydraulic outfitter. I think I read on another thread here that you can get one from GM as their transmission uses a rubber gasket. This will save you the headache of...

Paint info for Canadians Not sure if the US has a similar book, but here in Canada we have this used car guide called the "Lemon-aid Car Guides". Here is a link to it http://www.lemonaidcars.com/background.htm . One of the interesting things this guy does in his books is he studies and presents...

I was also going to suggest a holster behind the knee bolster, it doesn't take much, just a quick tug and your handgun is righ there. Here is an good link www.packing.org that lists all of the various state laws for CCW, open and general gun laws including a state-by-state reciprocity map (use...

I propose we change the thread to "Vehicle Safety" anybody with me? (not) Its true isn't it and often it is not only the small companies that feel forced to make this decision. Even for someone with big pockets like Dodge sometimes (apparently, mind you) it seems like they choose not to test...

I really don't feel I have been showing-off, it is just that this is my background, I was actually trying very hard not to be condescending, which can sometimes be hard to do in this format, you can't really read a person. I am sorry you feel this way. Otherwise I like your post we actually...

My intent here was simply to engage in the discussions that happened at the beginning of the thread. Yes the original first post in the thread was about the length, but it quickly went the direction of the price of the arms and to a discussion about alternative designs (i. e. nodular iron). At...

Here are some photos from the Component Failure Museum at Open University (http://materials.open.ac.uk/mem/mem_mf.htm). In response to your quote above: Also not uncommon to see them fail in fatigue, yet you seem to have blind faith. And very graphic proof showing that it is not only thin...

Better than tube? I was admiring the photos of the control arms posted in the thread above. They do look nice (now if they were just made from steel... just kidding). Does anyone know if they are right and left hand threaded so that they can be adjusted on the truck? One advantage that the...

Well we agree on something! Says who? Perhaps you should have prefixed that statement with "In my opinion... " I mean, come on, if the part were made from say, ice, would (in my mind) disqualify it from being considered as a part of my truck, but not according to your statement. For my...
