V4 Racing Engines
The HIGGS HAWK V4 E330J/G Diesel is a clean sheet combined cycle, spark ignition, multi-fuel solution for the needs of today. Weighs in at only 306lbs / 139kgs.
HAWK E330J/G Features
But at the end of the day, much of GP racing is still a power war, and it was still no match for the narrow, well-balanced, and massively powerful V4s that dominated the grid. Once Honda went full-bore into both two-strokes and the dominant V4 engine architecture, they became virtually unstoppable on the racetrack. Honda unveiled a revolutionary idea with a 1992 V4 that was timed to fire all four cylinders within 65-70 degrees of crankshaft rotation — the so-called 'Big-Bang' engine. Along with a balance shaft that neutralized the single crankshaft engine's gyroscopic effects, the 1992 NSR500 was a breakthrough.
V4 (350hp-500hp) E-330J/G and E-330J/G-T clean sheet design engines. These engines will demonstrate our unique design for achieving the needed horsepower while keeping the weight of the jet burning engine at or below similar AVgas versions of these engines.

A very big punch from a small package
One of the most attractive features of the HAWK V4 E330J/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. And that’s not including the challenges and headaches associated with forced induction installs. The Hawk V4 really 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 upto 50,000′ and 500hp.
Performance
V4 Racing Engines
Our design enables combined cycle engines to compete with four-cycle engines in terms of fuel economy, 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. This 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 the two cycle engine. With this combined cycle design two cycle engine technology, combined with the enormous 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 almost 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 (EN 590), 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 bio derivatives.
Hydrogen gas.
Racing V4 Engines
BSFC, 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 ports 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 of the two cycle engine, which may now be more efficiently scavenged.
The port layout adopted concentrates the scavenge flow at the wall of the cylinder opposite the exhaust port. This compares with more evenly dispersed scavenge 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.

Midget Engines For Sale: Sawed In Half 350ci Chevy Blocks, Heads, And A Tiny Blower – V4 Awesomeness
Sometimes the simple solution is the right solution. In the case of these V4 midget engines, the proof is in the pudding. Using small block Chevy blocks and cylinder heads sawed in half, specially made Moldex chankshafts, and quartet of small block pistons and rods, these 175ci mills (apparently blown!) made plenty of power to shove the little race cars around dirt tracks all over the midwest. We know of a guy named Chet Wilson who has an engine building business in Kansas who was known for these types of engines and while we can’t be sure, these could be a couple of his old mills. When you think of what these things are and how they work it isn’t that crazy an idea, but it sure looks nuts, right?
We wonder what they would have sounded like, especially with the 3-71 blower working hard and blaring that exhaust note out of the pipes. We’d have to imagine that these things ran on alcohol without a cooling system although the one photo where the front motor plate is shown seems to indicate that the coolant passages were being used. Again, it seems insane, but those passages are in the same place that they were when the front four cylinders were there so why not use them? The heads are listed as “Pontiac” pieces in the ad which we think indicates that they’re old NASCAR heads that have been lopped in half for use on this engine. We tried in vain for a long time to find YouTube video of a V4 Chevy running and couldn’t. There are other V4 engines, but not these guys up there.
The “half a Hilborn” is sweet, the intake manifold under the little blower is cool, and the whole thing is just a curiosity that is begging to be put in a vintage Midget or even cooler, some sort of land speed racing vehicle. Hey, Bonneville or miler people, get on this weirdness now!
Thanks to Ron Ward for the tip!
