Geoff's Engine Emporium

[Geoff]

A Collection of engines that I am rather satisfied with.

I typically build my engines with engineering time taken into account.

Comments, questions, suggestions, and critiques are most welcome.

Willow Wisp
Designed as a NA VVL engine with linear power delivery and decent efficiency.
The main cam is set to 100 to significantly lower the required octane, allowing for a 11.2 to 1 compression ratio and a 15 to 1 air fuel ratio. The lower VVL cam rounds out the economy and VVT allows it to run somewhat smoothly. A side effect of the large main cam is that 14% more peak power can be achieved with a larger diameter exhaust, with a small decrease in efficiency. This allows for a separate sport trim with minimal additional engineering time.

Aftermarket exhaust mod = +14% power.

Somewhat high idle speed and low smoothness.

Edit: This engine is/was completely broken by the September 15 2017 beta update.

This looks like a decent first effort as far as UE4 engines go. My only complaint is that it isn’t very smooth due to the initial cam profile being as aggressive as possible, but otherwise, it has a lot going for it - cheap, reliable and economical with a decent amount of power.
