Thread: Interesting potential repower

I found this paper which lists the BSFC of a bigger detroit.

The best it acheived on normal diesel equates in metric to 257 g/kwH. That's quite poor by modern standards, a 4BD1T will do about 210 g/kwH, a VW 1.9 TDI does 197g/kwH at best point.

So expect a detroit to chew through 20% more fuel, probably the same as an indirect injection toyota.

Look at overall cost per kilometre. An injection system overhaul on a Detroit costs about $120 per cylinder, not $150-200 per injector plus $3000 for the pump. Serviced properly my 8V92t's did 600,000 MILES without overhaul. Many did 1,000,000 before an in-frame overhaul. I was advised to go into DDA oil analysis and they would tell me if the oil needed changing. Result? over 100,000 miles with only top-ups and filter changes. My Detroits used no more fuel in line haul service than competitive engines of similar output in similar service. Running Brisbane-Sydney-Brisbane at night, grossing 40-44 tonnes and doing the one way trip in 14 hours regularly. Good torque at cruising rpm does wonders for fuel economy and average speeds and Detroits have torque from clutch engagement to governed rpm.

Now that you guys have me all interested, what gearbox would you put the 3-53 onto? all that power at 1300rpm means monster torque, and then how would you correct the ratios to make up for such a low power band?

Cheers!

For a 3-53, probably use that Isuzu five speed with fast ratio LT230 that some people on here have fitted to 4BD1T's, 3.54 diffs, and largest diameter legal tyres. The aluminium 3-53 weighs only about 200-kgs, I am told. These are industrial engines that can run all day and night at governed rpm so top speed would still be respectable at 2500rpm, around 130kph with bigger tyres.

just found that while hunting for a sound clip to illustrate what engine i want for a F-600 idea......
