Oil Swirl Pot for Hewland FTR Oil Tank

Eliminate oil pickup issues under cornering and braking loads

  • Expand oil tank capacity
  • Efficient Oil-Air Separation
  • Compact Design

Hasselgren Oil Swirl Pot Hewland FTRHasselgren has developed an oil swirl pot to eliminate oil delivery issues under high g loads, both lateral and longitudinal, by expanding oil tank capacity.

The scroll top design incorporates three ports for scavenged oil, catch tank and engine vent in case of positive crank case pressure.

The compact screw top allows for easy filling and level checking and the assembly fits under most formula car engine bay covers.  The mounting flange has been designed to fit on the Hewland FTR style oil tank/gear cases but can be customized for other applications.

FormulaSpeed 2.0 Mazda MZR

Development for Mazda MX5 Engine

Hasselgren has been selected as the spec engine builder for the new FormulaSPEED2.0 race car which will participate in the Formula Car Challenge, sanctioned by NASA Pro Racing.

Hasselgren has designed and manufactured components to convert the production 2.0 MZR MX5 engine for a formula race car: billet oil pan, combined oil cooler/filter mount, intake manifold, race alternator mounts, oil swirl pot, variable valve timing engine tuning with Cosworth/Pectel ECU.  The car will make its debut this summer.

Small Engine Testing and Development

Single Cylinder Engine Development

One of the Hasselgren dyno test cells is currently being used for small high efficiency engine development with in-cylinder pressure combustion analysis and a 5-gas analyzer.

Controls have been adapted for an AC electric drive, temporarily replacing the water brake. This allows for much finer load control and motoring for friction studies.

Hasselgren has assisted several customers with novel engine concepts with design, manufacturing, assembly and testing services.

TransAm Ford Fuel Injection

Small Block Ford 310, Yates Heads

Crossover Carbon Trumpets, Individual Throttle Bodies, Bosch MS3.1

In Feb 2005, Hasselgren began the design for the carburettor-to-fuel injection conversion for Greg Pickett’s TransAm Jaguar XKR. Hasselgren was provided the worst performing engine owned by the team and turned it into their favorite power plant in time for the first Grand Prix of San Jose in July 2005 where they finished 2nd place in a nail-biting finish.

The conversion was constrained by the rules of the race series sanctioning body and the aggressive schedule; highlights of new custom design included: new cam profile, carbon crossover intake trumpets and aluminum individual throttle bodies for the Yates heads, crank/cam triggers per Bosch ECU requirements, carbon airbox.

1919 Miller Race Engine Crankshaft

Orginal Crankshaft Balanced

A merging of old and new technologies was achieved in the balancing of a 1919 Miller crankshaft which was so out of balance that the carburettors foamed the fuel and the engine could not run.

A CAD model of the crank was developed and analyzed for rotating weight requirement.  The total heavy metal required and method of attachment to the vintage crankshaft was designed – and it finally ran smoothly in the original engine, first on the dyno and then in the car.

The 1919 Indy Race Car, which ran on the wooden track at Indianapolis, ran again at the Monterrey Historics in 2008.
