    Lightweight Racecar

    Mad Mechanics

    I'm designing a small racecar.

    Using .5" square mild steel tubing.

    Probably be powered by a little 4 cylinder.

    Seems like a fun thing to do.

    Happy Holidays!

    Mr. Burton

    Thank you for the response!

    Plan to get it rolling with lawnmower engine.

    Later on have an engine with the right power.

    Overhead valve 4 stroke not 2 stroke.

    Want it to be quick but not over stressing chassis.

    Going to have transverse leaf springs front and back.

    Suspension will be 4 link inline or might see how single link holds axles with leaf spring.

    Merry Christmas!

    harbor freight has a few choices that aren't to expensive

    sounds like a go-cart set-up

    Not quite. That's just the first time around.

    Nice thing about rear engine chain drive or VW type is it

    leaves you free to design rest of car.

    Car will be MGB or Triumph Spitfire size.

    Might just use British 4 banger or Volvo 240 type drive train.

    If it needs a little more power a V6 but that will be in the testing.

    Goal is to have a car that goes 50-60 mph in the straightaways and handles.

    Just a fun project.

    Merry Christmas!
