Q: Can I buy a H1 or H2 engine?
A: The H1 and H2 engines are no longer sold. They have been replaced by the BOLT4 and MAXI V8.
Q: What do these engines cost?
A: See the Pricing page for more detail. The BOLT4 engine kit is about $18,000 but varies in price depending on scope. A complete dyno tested engine is about $28,000. The MAXI V8 cost about $29,000 for a kit and $45,000 for a complete dyno tested engine. Price varies considerably with the build specification and scope of supply.

Q: Do you have a kit so I can install this engine in my (Miata, Geo, S2000, Focus..... )?
A: We do not have kits for production cars. We can provide bell housing and adapter plates to fit most gearboxes. In most cases, the cost of the engine and installation and the fact that many ancillaries like AC cannot be connected to the engine often makes such a project impractical. But there has been strong interest is using these engines for recreation of famed small liter vintage sports cars. In all cases, the best application for these engines are cars (usually race cars but not always) that are very light weight. These applications can best benefit from the unmatched high power density (hp/lb or hp/displacement) these engines offer.
Q: What will Hartley Enterprises be doing going forward?
A: We will continue to develop engine technology for the recreational market (off road). When new products are available, they will be announced on this website.
We have a strong interest and belief new electric car technology can benefit by the integration of a high efficiency IC (Internal Combustion) engine. If an IC engine can run at over 50% thermal efficiency, it will be more efficient than a pure electric car with batteries being charged on the grid. An IC engine can achieve this efficiency level if designed to run at or near wide open throttle as is possible in an automotive plug-in arrangement. To date, the engines used for this application are large, heavy and do not achieve the efficiency level that is possible. We believe at significant improvements can be made in power density, packaging and, most importantly, efficiency.
Q: Where are you located?
A: We are just outside of Milwaukee, WI USA
