tractor diesels vs. pickup diesels

Actually, NOW the Packers have 2 more games. Good looking performance by the Pack after a near disastrous start. ( I hear Brett has a twin turbocharged Diesel tractor and a diesel truck - there now we're back on topic!)


But watching New England, (whew!) the second one is going to be tough! The Pack will probably only win by 10 or 14 pts. (Rumor has it that Tom Brady has an electric tractor.

Go Pack Go.

Also Go Giants Go!!

I hear if Brett isn't driving his tractor he's hunting or weed eating.

I wonder if the BIG NH in the commercial is his. I'd have thought he'd be driving a green and yellow(gold).

I almost had heart failure in the first 5 minutes but old Grant made up for it. They looked like a Super Bowl team yesterday.

Probably not a pure electric, almost surely a gas electric hybrid, probably a Toyota Prius conversion.

Honda may change all the diesel theory. The following from Car & Driver:

From the Tokyo auto show comes confirmation that Honda痴 2.2-liter diesel engine will come to the U.S. installed in the 2009 Accord. The aluminum engine is fairly conventional in that it has a balance shaft, dual overhead cams, and high fuel pressure. The redline is around 4500 rpm; that痴 where the Euro-spec diesel Accord we drove topped out.

The VW TDI that I drive tops out at 4700rpm. I know folks that have chipped their car, and done other work to go with it, and they are pulling to 5500rpm. It is all in the fueling and the timing. Although there is a limit due to the slower burn of diesel fuel, I suspect 5500 is about it for the VW's as I don't know of anybody who has pushed them further than that.

Somewhere I read the use of automobile energy: 30% consumed in heating the engine-30% goes out the tailpipe-30% to the rear wheels??

I was working with the load on the engine to do it's work. On many auto's thirty percent load is high, on many of the new trucks the 60% number is also high. These numbers are what is often quoted for the applied load.

I figure a auto closer to 20% and a larger truck at 40% unless working in hills. Tractors are still in that 90% bracket.

So you gonna post a link to the magic foo-foo that makes a diesel run up to 5500 rpm?

Seriously, I have not heard of it and would like to know more.

JB- There is not one page that shows the magic it requires. Here is a forum that is a good place to start, it is all geared to the VW TDI.

TDI Power Enhancements - TDIClub Forums

Chips by "Rocketchip" out of Penn. There are others, he is just one that comes to mind at the moment, and the one I am using.
Hybrid turbos by "Kerma" out of Utah, VNT22 turbine/VNT20 compressor
Front Mounted Intercoolers
Lift pumps from a PD
Larger Nozzles for the injectors
Larger, higher pressure injector pumps
Stronger head bolts
Etc, etc, etc.

With apologies for the thread hyjacking....


And you get 5500 rpm with your diesel?

I looked at that TDI page and several others last night and all the dyno runs were 4400-4700 rpm with power dropping precipitously at the end. That's high for a diesel and to be expected. I even tracked down a couple chip tuners and reviewed their power claims and dyno charts. None went past 4700 rpm. Made good power from idle up to 4000, for sure.

Still, those TDI's are some powerful little buggers. I really don't know why we don't buy more diesels in the USA. Love my diesel truck (except when the poor fuel gives problems).

RPM limits in a diesel have nothing to do with the fact that they're "diesels" at all.

Some "diesels" spin at 120,000+ rpm (turbine engines!)


Piston diesels are typically low RPM not even because of the burn rate of diesel - it's because of the piston speeds of the longer stroke, the longer stroke is required for the high compression ratio; the compression ratio is required to achieve auto ignition temperatures...


Want to see a high revving piston diesel?

Here's one for roadracing, based on a Gm Duramax, check out the videos: Banks Sidewinder D-Max Type-R | Tube-framed, roadracing pickup | General Motors Duramax

Another of Banks' drag truck:
Banks Power - Banks Debuts Sidewinder® D-Max Type-D Drag Race Pickup at SEMA


I spent the last 2 years working on a standalone Engine Management System in southern california, and I was lucky enough to get to hang out with the Banks team during the first pass for the drag truck at the Ontario track back in September, on it's shakedown run the thing went 8.90 @ 155mph, now it's gone in the sevens at 165mph+

They shortened the stroke on the crank by a LOT, to be able to wind the motor up to high RPMs. The torque figures go down, but the HP numbers go up and the powerband gets broader.

Also, the 5-cylinder Mercedes engine from the 3-series 1980s (the last of the cast iron Mercedes diesels) revved to 5500rpm from the factory, if you're looking for a bone stock high revving diesel. The service manual even has a procedure for governing the engine at 5500RPm by holding it there in neutral. I drove a 300D Turbo for a long time, it indeed would wind up to 5500rpm if you held the throttle down. That was with a pre-chamber old school diesel.
