Created a series of 4.6L engines.





From top to bottom:

1. Base variant. 1 camshaft per bank (SOHC) for reduced cost, 4 valves per cylinder, regular intake with 1 throttle body per cylinder bank, short cast iron exhaust headers, and heavy flywheel for smoothness and greater lifespan. Runs on regular unleaded fuel (87 AKI/91RON)

2. Mid-grade. 2 camshafts per bank (DOHC) for less friction, performance intake, tubular headers, slightly lighter flywheel, and slightly increased rev limit. Runs on premium unleaded fuel (91AKI/95RON)

3. Top-grade for now. DOHC, individual throttle body per cylinder, lightest flywheel, long tubular headers, higher rev limit. Runs on premium unleaded.

But... the 1st engine is DOHC on the pic.

looks single to me

Ive manged 1000 hp and 850 Torque out of a V8 so far

[HashiriyaR32]

What could be my most powerful engine so far.

[thereddaikon]

how so? in total output or in power per liter?

[HashiriyaR32]

Total output. I'm not going completely all-out here and making max displacement max power engines running on 100ROn fuel.

I've found up to a point that a single large diameter exhaust makes more power, until you run out of piping size. I only use duals if I'm going for stupid power (1200+hp), or trying to be really quiet (4 mufflers rather than 2).

My attempt at the Mercedes-Benz M113 engine as seen under the hood of the E430.

[thereddaikon]

Funny, I made the AMG version of that same motor found in the C43 last night. It's a very conservative tune.

[HashiriyaR32]

OMNOMNOM fuel.

1969: Peak of the musclecar war. Grey-Skies Industries releases a mass produced 10 liter (610 cubic inch) V8 with 700 horsepower and 700 lb-ft of torque. By 1970, the entire Los Angeles basin resembles the surface of Venus.

[thereddaikon]

I made the 6.0L AMG Hammer V8. The hard part was actually getting the power in line with the motor, even with mechanical injection it wanted to make much more.

[thereddaikon]

anyone notice how OHV engines start to run out of revs around 6200-6300rpm regardless of the cam and timing? I was trying to make a Z28 camaro engine which revs to 7k rpm and makes max power in the higher 6000s but i couldn't get it up there without destroying the power curve due to this limitation.
