I'm using a temp gun now. I take a reading... pull away and count to 5, re-check and the difference could be 10 degrees Farenheit!

As I'm running a $300 plus dollar motor I don't want to fry it because my temp gun sucks.

Any help would be greatly appreciated.

there is only one best temp gun , not cheap at 250$ but it is the exergen gun !!!! the standard in pro rc racing !

+/- 10 degrees isn't too bad. Just go a little on the rich side and use the temp readout as a guide. keep it under 240 and you'll be fine.

I was looking for a temp gun aout a year ago. My son and several friends bought cheapos that never did live up to their expectations. I won't name names.

At the time a lot of people were talking about the Ray-Tech. Nice, but I didn't want to spend 80.00. Then I found this one at Napa, an auto parts store.



It's almost identical, but made by Performance-Tech. It was 40.00, and I took a chance. I've tested it against a number of thermometers, boiling water and even ice. All were within 5 degrees.

Well worth the money, and I can't say that about the others.

Exergen DX501 Infra Red Temperature Gun. It is by far the most accurate temperature gun you can buy, and is what most of the top drivers use to measure the temperature of their engines. This temp gun is the most accurate you can get, so if you want the best, this is it PERIOD!!!

its on the o'donnel site, they only make one,

You guys are silly, a little saliva on the head is always accurate. Besides, we all know how to tune a motor so who needs a temp gun?

boiling point is at 100c so what is spit going to prove

iTrader: (5)

Water boils at 212 degrees Fahrenheit. So if you spit on your head, and the spit doesnt boil, you're below 212. If it sizzles right off you're way above 212. If it boils a little you're just about right.

How many of you guys own the O'Donnell Temp Gun. When I read my temp, it reads a little high. I guess this is because it's reading the glowplug temp and not the head temp. Anyone agree? Mine temps roughly 25 degrees higher??

i bought one of those odonnel temp gauges to have a smaller gun , that thing is not too bad , within 20 degrees only if you have an odonnel head otherwise its about 60 degrees off with a stock head . measuring against the exergen gun that is . i threw it in the pit box and that is where it stays . the only reason you should even need a temp gauge is to make sure your engine is staying consistent , tune with smoke and power not always by temp gun . example , i have two identical 5 port novarossi engines , one makes insane power at 175 - 180and i cant run it any leaner or it'll blow , the other one wont make near as much power in that temp range , doesnt start running good till 245 - 260 no matter what pipe what clutch , head shimming , etc. so tune to what the engine likes , not necessarily temp.

Has anyone seen the Raytek MT6 or know anything about it. It seems to be middle of the road at $100 vs the $250 for the DX501.

Again, thank you one and all for your input... keep it coming!
