I was wondering about new frames. My frame is not perfect but it's not totally rotten either. But I am building an engine and tranny combo which should be good for 700-800 hp, which might expose any weak spots in the frame.
I saw some pictures in the gallery of someone with a totally new frame under their 57 and was wondering about it. Is this a homemade peice or something bought?
Any insight or thoughts on the matter are welcome.
An original frame will twist like a pretzel. Look at a convertable frame for inspiration. The OEM frame is two stamped C channels welded together to make a boxed frame. The welds are intermittent to allow for flex and ride quality. Clean the frame, clamp it down to a frame table (or something like it) for measurements and to avoid warpage and weld it continuously from end to end top and bottom. Fab a beefier cross member/ driveshaft hoop and another member in front of the rear end. Generic mid frame support kits are available. Look at an Art Morrison frame for ideas.
I would share pictures but PhotoBucket blew up!
Any car w/700+ hp needs a full rollcage! That will stiffen it up enough.
It costs more to build a car to handle 700 than it does to build the motor.
Goodluck,
Ron.
