Boss Motorsports

Thank you, I appreciate that. I'm sure that your engine is quite the engineering feat. I have a 110 CI twin-turbo motor that you might appreciate. I dropped it into my entry for the Super Go Karts competition. Maybe I'll upload that.

If it generates at least 300 hp without competition limitations, I'm in pleasure to see that.

By request we present, for display only, the race tuned Boss Kart Motor. As a one-off prototype that requires refinement, Boss Motorsports is not offering the Boss 110T for sale. We are currently researching producing similar performance numbers with a similarly sized Turbocharged Inline-4. The Boss 110T was an experiment on how small we can make our V8 Performance tech. At a high monetary cost and with major turbo lag, we produced an engine which makes over 700 HP out of less than 2 liters. While pleased with the end game, this design does not achieve pure tire burning power out off the vehicles it was designed to fit in. We at Boss Motorsports believe that every cubic inch should be utilized for power. After extensive peer review and a less than ideal competition result, we will be retiring the space-wasting sub-2-liter V8 design for a roughly 2L I4 design that produces more power sooner at a lower cost than the Boss 110T design.

So while the design has been retired, enjoy a unique piece of Boss Motorsports experimental history.

Boss Motorsports is proud to introduce the Boss 550 TT. This motor is another original Boss Big Block V8 like the original Boss 432. These turbocharged motors are specifically designed for high torque demands such as drag racing or heavy duty trucks. The 550 TT comes in 3 variations: the entry level bargain, the maximum performance variant (for the drag strip), and the maximum economy variant (for heavy duty truck use). No matter which variant you choose, you're receiving over 100 ft-lbs of torque per liter of displacement as well as having emissions under 40 on all 3 variants.

The Bargain:

The Power:

The Economy:

These motors are all available directly from the Boss Motorsports tuning shop. Simply send an order to KLinardo via PM and select your variant.

These motors were all designed for the "V8 Engine Build [Challenge]" which can be found here: http://www.automationgame.com/phpBB3/viewtopic.php?f=34&t=6862&start=10

How do you make such powerful engines so efficient?

He just makes engines with lots of displacement, in true American fashion and runs turbos with reasonably high boost. Because of this, I imagine it's possible to run the fuel mixture lean without hurting the power too much.

Edit: Also limits his power by his redline.

These motors were all designed for a competition where the emphasis was on 100 Ft-Lbs per Liter of displacement. Since the required displacement was 9.016 - 9.021 L the required torque was 901.6 to 902.1 ft-lbs or greater. There was also a Production Unit cap of 300 PU and an octane cap of 90.0 RON. In addition, there was a minimum reliability requirement of 80.0

I don't always tune my engines this way, but I liked how these turned out, so I decided to publish them. A quick adjustment of the rev limiter allows for the full power band to be utilized. Again, these motors were designed to produce impressive torque curves. A very lean fuel mixture, modest cam profile, timing adjustments, and tinkering with the amount of boost and turbo design resulted in the 3 variants of the Boss 550TT that you see here.

You'll see I also produce smaller N/A engines that are tuned for power, completely ignoring economy: my preferred method of tuning.

[Microwave]

I usually design my engines with maximum power in mind, then once I've finished drawing as much power as possible, I'll go back and assess whether the economy is good or not (15% is perfectly fine )

[dzlockhead]

Yeah but my best engines with economy in mind achieve about 28 percent, this is just impressive in my opinion!

[KLinardo]

There was a minimum of 25% efficiency with emissions being 40 or lower, so I didn't have that option.
