what do you think about guys running gas engines? if you cant run electric?

[Haynes Forest Products]

well gas is the next best option Im thinking propane would be nice only because Im tired of smelling like gas at the end of the day.

You can certainly run gas engines just be sure to match up the proper HP and speed of the vac pump. I'm not sure of the ratio but I know you need more HP for gas than you do for electric. Some one on the trader has discussed this before.

Is this another one of the dryline booster pump things? HP is HP is HP is it not? Do you guys say you need a bigger hp gas motor compared to an electric motor due to the rpm's not the actuall hp?

[brookledge]

This thread is starting to get off topic but I'm sure someone can help, All I know is that I have been told that if you have, say a 3HP electric motor and you want to run the same thing with a gas engine you will need alot bigger gas engine like a 8 or 10 HP to equal the electic regardless of the rpm's.
I might be wrong that is why I'm questioning it

I could be wrong but I understood 1HP electric equals 2 HP in gasoline....

[caseyssugarshack93]

I was told if you have a 2.5hp electic you need a 5hp gas, and i think thats pretty acuarte

gas engines don't have the torque that elect motors do

[3rdgen.maple]

Ok guys here is the answer to the mystery. Horsepower = Torque (lbs-ft) X RPM / 5252. If an engine or motor can produce a little torque at high speed, it can produce as much horsepower as another engine that can produce a lot of torque but can't run as fast.

Remember once you get a electric motor started and especially the bigger ones the armature weighs a lot so the stored energy makes it turn with more force easyier. With gas you are working on the combustion of the fuel to keep the piston turning at the same speed and with the same force. Thats why its easy to over work a gas engine if it's not big enough. The old one cylinder bangers had heavy flywheels for a reason the piston just kept the fly wheel turning and that gave you the power.
