scaling the chassis

[pepsi]

hi, im considering a build and i've found various adaptions of the original chassis design to accommodate different sized engines. but, i was wondering if someone with more knowledge could tell me if it would make sense to simply scale up all the chassis dimensions by a percentage, with bigger/thicker tubing, bigger wheels etc .. in order to fit a bigger engine?

if i understand it correctly, for optimum handling, a serria steering rack needs to be shortened? so with a scaled up chassis this could just be shortened less? BUT i would need to extend prop shaft?/drive shafts? and steering column? anything else?

could i still use all the suspension components suggested in the book? or because they are relatively smaller would this upset the suspension geometry?

many thanks, matt.

Probably better off looking at the McSorley 442,all the hard work has been done and i think you can get bodywork to fit.Here is quite a good link;

The Rover V8 engine fits the early Locost which is narrower than the haynes so why make anything bigger? Just because it's got a big motor doesn't mean it will be any good. Small revvy motor in a small car will out do some fat lardy thing with more horsepower than you can use.......
