Does anyone have the powercurve graph of a standard Pinz engine laying around?

That and if a 2.7 could be posted as well, that'd be awesome.

This site has the Maintenance manual posted on line.
The Torque/HP curves are there. As far as a 2.7 goes
that will be self-relative based on Dyno pulls, since this
was not stock.

Dah! Now with the pointer

It may just be the fact that I don't know french, but even with the aid of Google translate, I was unable to find the power graphs on that website. Is it under a certain section I may be missing? Thank you!

Ha! Just kidding, I found it.

For those who struggle with the French (and metric) PS is roughly equal to horsepower.
m/kp is kilopond meter and one of those is equal to about 7.23 ft*lbs.

So max torque occurs at 2k and slowly falls off after that. I'm looking at the output of some small diesel engines which have a much lower max rpm and i wonder how it would work with the stock gearing.

I wonder how many people drive within the 3 to 4k rpm range on a normal basis?

I wonder how many people drive within the 3 to 4k rpm range on a normal basis?

For a 710, anything over about 50mph is over 3k rpm... I'd guess that 90% of the owners run in this range at least part of the time.

With 31 inch tires I run at about 3400 RPM to go about 48 to 50 MPH. After I changed from 33's I did notice a change from about 2800 to 3000 RPM for the same speed. I can't get into my garage with 33's so I came down to 31's.
So for a trip of 400 miles I am running at that speed most of the time...except up hill. Then it is a labor to get over 20 MPH and most of the driving is above 6000 feet in altitude. Down hill is much better for speed but then I am constantly backfiring with the unburned fuel going through the hot pipes.
I've had the pinz for ten years now and sometimes I wonder if it is worth the trouble. Need more power.

Need more power.

20-30% more power is available - Ask Jim L. about his 2.7l conversions. My 8,000 pound 712W goes up moderate hills in 5th gear (1:1 in a stock transmission; 4th in the TD tranny I have) that I had to downshift to make it up before. Although I have the EFI system, I ran the 2.7l with stock carbs for a year first and saw the power increase. EFI did not make much difference in power but did improve starting and cold torque and overall drivability.

When we first did the EFI, we put the truck on a dyno (a challenge with the 712!) - saw a peak power at the wheels at over 60Hp, the dyno operator said he assumes that 1/3rd the engine power is lost in the transmission and other gearing (and would be worse than he expects in a Pinz, due to additional gears). So his interpretation is that my engine was peaking at well over 100HP. I don't know that I can find the dyno results anymore, but I'll post if I can find them.

Thanks for the tip. Left a message on his phone. Hope to have this done as his work load permits.
Have stock carbs rebuilt last year.
