big claims for a 6.5

[great white]

800+ lb/ft at the wheels?!?

It is a p400 block by his description in the video....but 800+ lb/ft at the wheels?

I dunno.....

If you listen carfully he said 875 Newton-meters at the wheels which converts to about 645 Ft-lb... Does that sound like a more attainable number?

He said, "875 Newton Meters at the wheels."
That's only 645 ft lbs of torque.

He also said it has a forged crankshaft and a 2-piece block ; sounds like a girdle, but I don't know everything.

They seem to talk about a 6.5 that's different from ours, on their website;
"6.5L CHEV DIESEL
Originally designed as a ‘workhorse’ engine by GM division Detroit Diesel, this light truck engine was fitted to Chevrolet & GMC pick-up trucks and SUV’s including the Suburban from 1982 until 2000, at which time this engine was replaced by the 6.6 litre Duramax range. "

OUR 6.5s were originally designed to be cheap to build and economical on fuel, as I have read.

They also say,
"The 6.5 has a lot going for it. It is available with electronic or mechanical fuel injection. There is a 12-volt wire to the fuel shut-off solenoid, and another to the oil pressure gauge, so wiring on the very popular mechanical pump is easy.

This together with sealed hydraulic roller cam followers, a double roller timing chain and mechanical indirect fuel injection make the 6.5 a reliable, low maintenance proposition. For these reasons, this engine is the natural choice for rural Australia, for simplicity, robustness and longevity.
You can expect 500,000 kilometres from a new 6.5."

no news there...

I keep staring at that roots supercharger settin' on that engine. :drool5:

Ahh, N/m makes more sense.

645 ft/lbs still pretty high from the design though. Especially if that's what's measured at the wheels. you can count on around 680-700 at the crank with those numbers.

But it sure sounds like he's talking about a p400 block to me.....that's the only design that "bolts on to the bottom" as he mentions.....

they probably have an inj pump similar to a DB4 or high output DB2 that will flow enough fuel to make that power

X2! And wondering if they rigged it sequential with a turbo?

I like the way your thinking. You could use a big turbo, like slightly bigger than the ATT.
