Typically the chassis was lowered four inches, called 'underslinging', the wheelbase was slightly extended, and an additional front cross member riveted to move the motor back eight inches for better weight distribution. The mechanical brakes on the rear wheels only still led to some 'wild rides'!
The basic 40 HP motor was usually 'hopped up' to over 70 HP with a Roof or RAJO Overhead Valve Conversion (OHV), a hot cam, balanced crankshaft with pressure oiling, and side-draft or up-draft carburetors. These little cars were very competitive, often exceeding eighty miles/hour.
This high resolution 1,552,560 poly (disc) 1,770,218 (wire) poly CAD model was created in SolidWorks™ from research and many photographs. It is full-size (1:1) and accurately scaled, and includes a fully detailed (less inner parts) RAJO Overhead Valve Head (OHV) and dual side-draft carburetors.
The modeling quality allows for extreme close-ups and rendering. It is ideally suited for hero and foreground shots within early 20th Century period sets and CG’s.
All appropriate surfaces/features are UV mapped. The No. 5 is optional, created as a projected split-line surface for UV mapping; it is not solid geometry.
The SolidWorks™ model was converted to .obj using SymLab Composer. Renderings were created in KeyShot2 from Luxion.
