Megasquirt MS1/Extra Rover V8 - Troubles Starting Cortina Uprights
My Design Assumptions :
- I could get a friend to make some replica Cortina uprights.
(Similar to Rorty Designs) or
I bought some new aluminium ones (e.g. from Rally Designs) - Wheel and Tyre Diameter is 556mm (195/45/15)
- −1° Camber.
- King Pin Inclination (K.P.I) = 4.3° (Cortina Mk3/4/5)
- McSorley 442 chassis with Locost style mounts.
- Chassis to ground 150mm (6inches).
- Front track width = 1452mm (Sierra − In case I go this route)
- » MK3/4/5 (TC/TD) Ford Cortina Upright Drawings here
Results :
- The top link would be approx 296.5mm long and declined 5.9°.
- The bottom link would be 372mm long and inclined 3.5°.
- A−Arm length ratio : 296.5/372 = 0.797.
- The Roll Centre would be approximately 115.3mm.
- The swing arm length would be 1462.9mm.
Conclusions :
Although the set−up was better than many I’d seen, there is obviously great scope for improvement. For instance, to minimise the large scrub radius, huge front tyres (225+) with a large offset would be needed.
The car would have a medium swing axle length (1m − 1.8m) producing :
- Reasonable kinematic roll centre location.
- Medium roll centre movement sideways for given variation in height.
- Wheel angle in roll mediocre, worst on inner wheel.
- Wheel angle in bounce mediocre.
- Mediocre to bad performance in scrub.
