F1 technology - that's how they used to rev to 20K RPMs.

This will be the greatest next step for street performance guys. We'll be able to make a calibration that will sit and lope like crazy at idle, but then make excellent off idle torque, while at the same time being able to make excellent upper rpm power. The old compromise between torque or power will be negated, we will have BOTH from the same setup. This compromise is exactly what the LT5 was attempting to solve. With the port throttles closed and only 8 injectors firing, crisp off idle /low rpm torque is available, but when max power is required, the Port Throttles open up and all 16 injectors fire.
The LT5 is an amazing engine, esp. considering when it was conceived.

MAN Diesel & Turbo and Wartsilla are working on large marine engines using camless technology.
Warstilla makes engines of massive size. Here is a 10,584 hp Wartsilla starting up, not camless, but putting in perspective the scale of these engines. Can you imagine a 11,000 liter(2905 gallon) oil change? I wonder it that is WITH or WITHOUT the oil filter?lol
(I've done the conversions FROM metric for my friends South of the border.)

Output: 7800 kw (10584 hp, 42336 hp all four engines)
Displacement: 384 L(101 gallon total (96 Liter/25gallon per cylinder)
Consumption: 2520 L/hour or 665 gallon/hr, HFO 380cst
Lub.oil in system: 11000 L 2905 gallons

Dimensions:
Lenght: 9.49 m 31ft
Height: 4.72 m 15.4ft
Width: 3.18 m 10.4ft

Paul,

Don't forget that the Gen III LT5 that Graham has installed in a 93 Ruby also was to have included a precursor to VVT, effectively eliminating the need for the secondary throttles. I believe it was also going to utilize cam followers? Unfortunately, since none of that mechanism was ever built, Graham was not able to incorporate that design element into the motor he assembled. As it is, the Gen III cylinder heads and top end produced ~475chp without much tuning.
Imagine a 475-500+hp 5.7L DOHC motor showing up in a mid 90's Corvette.
WOW!

I'm with MAN Diesel & Turbo and here is a cross section view of our ultra long stroke G95ME two cycle marine propulsion diesel engine which have no camshafts. The exhaust valves and fuel injection are hydraulicly actuated by a computer controlled servo system. The largest examples have a bore of 95 cm (37.5 inch) and stroke of 346 cm (11.35 feet). The 12 cylinder version of this engine produces 112,000 hp @ 85 rpm.

Maybe with a hood scoop it would fit in a C4?

Cool! What is the torque?
I love inline 12 cylinders!

Wonder what Callaway could do with it?
