You think that's too much? I dont plan on it making more than 450 at the wheels. I will have him go through several driving courses b4 he actually drives the car. I know kids will be kids, but locally I have noticed the ones that hurt themselves are given high powered cars w/out any training. I plan to have him well trained with all the supporting safety mods.. He will have a roll cage in the car and all the other safety bells and whistles. First time he gives me the impression he is a hot dog the car becomes mine and he will end up in a honda civic....
Sounds like a cool project, and yeah, I'll bet you spend much, much more than projected.
Are you doing everything yourself including paint and body?
Body and paint is pretty expensive now days unless you find an alcoholic paint sniffer to do it on the side between drinks and whiffs, ha, ha.
Kidding, but make sure you get everything in writing to the smallest detail and get a solid agreed price even if the body shop tells you they can't do that.
Tell him that's the only way you will agree to it and you will just find someone who will.
As far as thinking your Son will not hotdog the car, you are dreaming.
I know i would with that much power under my seat, and I don't know any kid that would not push it when dad is not around.
I'd definitely let him drive something else to get some experience before dropping him into a street machine.
