Exhaust Gas Coolers? Good or Bad

I run the gas cooler and the tape on the fuel tank and have found that with the two in place i get 45 seconds a tank more run time in a truggy and the fuel is 9 degrees cooler at the carby, so read into it what you will i have swapped the tank and return line three times for the same results, 41 seconds, 43 seconds, 45 seconds and 8, 9 , 9 degrees cooler fuel which adding these all up in the end you get a fraction more run time, or need less fuel at each stop and the engine runs that little bit cooler due to colder fuel which means you could even lean the engine a little more and maybe grab 1 minute extra run time ifyour looking for the fine line......
Leaks are about the only issue you can run into but then again the standard set up can fail all the same....sometimes stuff just happens

How do I get in touch with him? As a side note am I missing something by running the B5 and B6 over the OS VSpec? I am new to nitro and read alot of good things about werks motors so that is what I went with. I do have a 2 gallon old Vspec and a new in the box Limited edition gold head Vspec.

"savagesam" have you run the same length of pressure line when you removed the gas cooler or a shorter one?
In general liquids need a long time to change their temperature and lots of energy.
7-10 minutes IMO is not enough time to heat it up to that extend where it will make a difference from the gas pressure. Not to mention the ability of any "cooler" to cool down the gas when it's constantly flowing into the tank as it goes down. Also a single tube with fines isn't that efficient to cool anything...you would want something to allow more contact area with the air going through.

I forgot to mention that the other reason for going with the Werks motors is that Ron's service is next to none. What other engine producer do you see always answering everyone's questions on the forum? Ron is always there if you need him and for a new nitro guy like me that's very important.

Yeah you have to tune them, but they don't change during a race... Without a gas cooler. It would take a lot to make the tune on an OS change during a race.
If the gas coolers help with tune consistency, that is another reason to use one, but still not enough for me. If I wasn't running OS engines that might not be the case. I'm a big fan of the "keep it simple stupid" philosophy. One of my biggest pet peevs is fuel system issues and air leaks. They're such a pain to deal with. They are hard to find, and can completely ruin a race weekend. I just like to keep it as simple as possible with the fuel system. Same reason I will NEVER run an inline fuel filter again. That's just me.

Exhaust coolers do work, especially in cooler temps. Worth it? Thats up to you. If runtime means enough to you to offset the added weight to the car, then yes.
