Re: Old School Rocket Car Build
EK's Grand Canyon jump was only 200', so a mere scale 20 foot'r would do it!

Re: Old School Rocket Car Build
The 1st have run is ok...but the front tires blow out when it gets going over 65mph...even if they are glued on...so at that point yes puckered tighter than a snare drum!

When you get her fine tuned bring her out to Idaho. The old Evel Knievel ramp is still there and the canyon is just begging to finally be conquered

Who do you race for ?
Me……. I race for me.
That’s impossible, I was told you need a sponsor to race.
Hey Cru ! Go balls out

Re: Old School Rocket Car Build
It would be interesting if you changed nothing but put a cinder block a foot or so behind the car and see if your MPH improves.
My engine stuck out behind the car so I could place it right up against a solid object, yours is just inside the body so I worry about the blast ricocheting back inside your car.

If a jobs not worth doing then its certainly not worth doing well.
