![]() It’s not unusual to use my supercharged W engine in aircraft and vehicle engine contracts for 3-4 decades after they are made, they are that good. But I’ve found these engine designs remain very useful for contract fulfilment as their component quality doesn’t matter for contracts (maybe it matters on whether you win it or not?, dunno, but just hire a lobbyist). I haven’t looked at the price too closely, but they seem as expensive as supercharging, but early on you simply can’t beat a supercharged W engine for an early, super powerful and compact engine type. ![]() I use Flat and V engines fairly interchangeably once I get both, depending on how many cylinders I want to fit.Įxpensive, complicated, but oh so much hp in a compact form factor. I’ve noticed these engines can be as compact as V engines, with similar price, yet be more smooth depending on the cylinder configuration. My go-to engine for compact, moderate cost, powerful engines. ![]() There is an interaction between # of cylinders versus bigger cylinders on numerous variables, but I usually let the smoothness of the # of cylinders govern whether I go lots of smaller cylinders or fewer bigger cylinders (for example, V-6 engines are more smooth than V-4 engines due to how the cylinders are balanced when in motion/resulting vibration).Ĭheap and reliable, but require longer chassis (Usually don't need more than a 3:2 length:width ratio though). Remember that the power rating is related to torque, so you often don’t want to tank torque too heavily if power is important. However, I’ve noticed the cost increase of supercharging isn’t completely horrible, in my opinion, then the cost of building a bigger engine + bigger chassis, so if you’re pinched for time or whatnot, it’s a viable option to supercharge imho, though usually a bigger engine in a bigger chassis will be a $150+ cheaper at least through the early part of the century. Third, if you’re strapped for space and want to increase horsepower, supercharging is a great early way to do so, though it will substantially increase the cost. Also, usually a bigger engine is cheaper than tuning a smaller engine for high performance, so that’s why I recommended larger chassis in the earlier section. Second, weight is surprisingly important, and often not too expensive to change around. It can be helpful, imho, to try to prioritize engine research till you get SOHC to help keep engine costs down (I usually prefer to design frequent engines rather than spend money on actual engine research as a way to boost research). You always want at least SOHC level of valvetrain. Using a longer or width basis, or spending more into allow chassis with longer or wider engines usually allows you to design cheaper engines to more than counteract the increased chassis cost.įirst, I’ve noticed that the SOHC and DOHC valvetrain offer significant hp improvements for almost no cost over the earlier valvetrains. So how does this matter? Leaner/lower weight chassis require less engine hp for the same performance and power, as well as increasing fuel efficiency (though there are tradeoffs, as for any of variable). So often if you’re building a budget vehicle, it makes sense to not push most sliders past ½ or ¾, unless very very important to the vehicle’s role.Ĭhassis end up for me being a lot cheaper than engines. I’ve also noticed that in general, many variables seemed to have diminished returns as you go from 0 to 100, yet cost increases without diminishing. For example, I’ve noticed that vehicle testing variables are much more cheap, even when maxed than when compared other vehicle design variables. Not all variables cost the same, so check to see which ones are more expensive. Please note I’ve only really played through the game 4 times through the 60s, mostly on stock 1.20, so most of my thoughts are focused around early and mid-game. For the way I design cars, engines end up costing way more than the chassis or gearbox and are also useful to procure engine contracts so I’ve had some limited time in my playthroughs to contemplate the pros and cons of some of the engine types and other things. I just wanted to post my thoughts on engine strategy.
