We are currently not accepting deposits and will notify subscribers once we are accepting deposits again. Your deposit payment secures your engine build request. Upon your serial number creation, we will contact you for a 50% payment which will initiate the assembly and engine build. Final 50% of balance payment (less your initial deposit payment) will be required prior to engine shipment.
A Big Punch from a Small Package
One of the most attractive features of the HAWK V4 E330 J/G is its size. As you can see from the images opposite, they illustrate very clearly the benefits of the added horsepower in a much smaller package. Shown here is an overlay of the Lycoming IO-540. Need we say more... For OEM's and builders alike, one of the biggest challenges is the firewall forward and getting everything to fit. That's not including the challenges and headaches associated with forced induction installs. The HAWK V4 truly lends itself with ease to the introduction of forced induction which is why we offer the HAWK as a E330J/G-T. The turbo version provides a mission ceiling of up to 50,000' and 500 hp.
Performance
Our design enables combined cycle engines to compete with four-cycle engines in terms of fuel economt, especially under cruise conditions. The crankcase, freed from any gas exchange functions, is well lubricated; the working processes being sealed above the piston. Isolation of the crankcase also permits a full pressure lubrication system to be used, as in four-cycle engines.

Reliability
Inherent piston cooling characteristics of the combined cycle piston design offer a major durability advantage over conventional two-cycle engines, allowing much leaner fuel delivery than can be sustained with traditional crankcase scavenging, where usually piston overheating and consequent seizure are common. The technology operates without complex mechanical components such as cams, valves, mechanisms, and the other various precision components necessary to operate them.
The absence of these mechanical components eliminates a large number of moving parts thereby considerably reducing the costs and maintenance requirements , whilst significantly increasing reliability and retaining the simplicity of two-cycle engines. With the combined cycle design two cycle engine technology, combined with the enourmous benefits together with their appealing simplicity, a new generation of light weight high performance power plants can be achieved, which until now, would have been nearly impossible.
Fuel Type & Consumption
This platform of engines has been designed from the ground up to be a true multi-fuel unit.
Designed to run on industry standard Jet fuel (Diesel (EN590), Jet A, Jet A-1, JP-5, DEF STAN 91-86, JP-8, DEF STAN 91-91, JP-8+100, Chinese Jet Fuel No 3). Will also run and perform on all gasolines where necessary, 80, 87, 91, 95, including 100LL, along with all bioderivatives. Other types of fuel include hydrogen gas, BSFCm 0.398 lb/hp-h (231g/kW-h). Pratt & Whitney PT-6 Turboprop by comparison is 0.507 lb/hp-h (308 g/kW-h) (on approach and idle 0.825 lb/hp-h (502 g/kW-h)).
Efficiency & Economy
It is necessary to emphasize the importance of the very high volumetric efficiency of the traditional piston controlled parts employed by the standard two cycle engine. Until now, no existing type of inlet valve could produce the essential requirements of presenting the maximum inlet area to the air in the minimum time. The new design outlined below, significantly increases both the utility and the efficiency of the two cycle engine, which may now be more efficiently scavenged.
The part layout adopted concentrates the scavenge flow at the wall of the cylinder opposite the exhaust part. This compares with more evenly dispersed scavange flows common in conventional engines. Scavenge flow within the cylinder provides, in effect, a form of stratified charging and explains improvements in fuel economy obtained with such a simple layout.
