I just joined this forum because I'm looking for the actual torque number for the 2016 708 cc motor. I've found the HP number but not torque. Can anyone help me?
Exactly. That equation JimP posted is accurate and notice that for the Ford 5.0, the torque rating given over the years is published at different RPMs for peak torque. Those are also flywheel rated which will be the same for the Yamaha engines since the HP number given will also be at the flywheel.So my 5.0 making 380 ft lbs in my truck only makes 127 ft lbs more torque than my kodiak ?
Interesting...I used your link to the calculator and put in 5000rpm and it came out at 50.7 ft/lb of torque...It is fun to play with the numbers and see the results.So my 5.0 making 380 ft lbs in my truck only makes 127 ft lbs more torque than my kodiak ?
Your not using the calculation properly..To find the torque of any engine follow this formula:
torque = Hp x 5252 / RPM
So for the 700 engine it is 48.3 x 5252 / what ever RPM you are at so if you are at 1000 RPM the torque value is 253 ft/lbs of torque
All you need to know is the RPM's of the engine
Every engine out there if you look at a chart Hp vs torque they equal out at 5252 RPM's
Yes but you don't make 48 hp at a 1000 RPM.... So this calculation if completely point less.I agree but I just stuck the rpm figure in for a example, not saying that was the actual toque number at that time. As you say it is dependent on the actual horsepower at the RPM's.
That's already been done by Eric at EHS tuning. The 2016 to 2020 Grizzlys dyno at around 33 hp at the rear wheels in stock formBut until we get someone that comes up with a tachometer for these machines and then sticks it onto a dyno all of us are just guessing
Even the 48 hp is suspect because that is quite likely at the flywheel and you would loose quite a bit through the transmission, belt, and the rear end.
