Is this the start of Workhorse again? Isuzu?

As they say, torque is real and can be measured, HP is just the result of a mathematical formula.

Just like any other engine/transmission combination. :W Now toss in the rear end gear and you can really confuse the issue.

The fact of the matter is this engine does NOT make diesel like torque. Through gearing, etc, it can get a decent tow rating, but it will never have diesel like torque.

The Cummins ISB, the smallest main stream diesel used today, starts at 660 #/ft of torque, and depending on the application goes all the way to 800 #/ft.

There is nothing wrong with a gas engine, but to say this engine will compete with a diesel is stretching it a bit.

People still care about the torque numbers these days? Funny.

Only those who understand it. :W

I wonder how many people know you have to know the torque # first to get to the HP number.

The original article mentions nothing about Workhorse or PSI. It only mentions that GM will partner with Isuzu AGAIN and put their badge on some medium duty trucks, like they are now doing with Nissan. GM will be supplying their own engine.

Looks like the current gas version of PSI 8.8L is rated for around 550 Lb-ft torque max.






PSI brochure indicates that the block is capable up to 1,000 Lb-ft.

The engine produces 550 ft. lbs. of torque. The torque converter is the multiplier, making it capable of over 1000 ft. lbs.

But will they have the expertise to work on the new motor being supplied by PSI? I have seen no parts available at the local stores, and the nearest Workhorse service center to me (2 hrs away) is a Chevy dealership. Will they train their mechanics to work on a PSI motor?

There are many stories on this blog about Ford dealerships turning away F53 and Class C chassis for warrenty work, so would a Chevy dealer work on a PSI motor? I am skeptical...

Not to worry; I am quite positive Workhorse/ PSI will make any and all information available.

Any Workhorse service center. :S
