The short answer is yes... probably...
We carried about 200 lbs, 80 up front, 60 on each side just behind the rear tires
This frame is definitely heavier... and quite frankly the run I went 246 made me start planning a new car... we knew too much about the old frame... yes, when Johnboy crashed it a couple of years ago it did remarkably well. His crash was about 190 MPH... the frame twisted about 1/4 inch... based on the J bend in the 1/4 wall chromoly axle and Johnboy's complaining about how much he was hurting afterward... it crashed pretty hard. Our fear was after 40 years since it's appearance on the salt the frame might be suffering a little cancer. In the early days the frame was also part of the cooling system... after that the body was riveted to the frame in spots and we had a lot of unsealed tubes with bolt holes... so there was plenty of opportunity... but it all stayed together and did its job
I expect this car to weigh a more without any ballast. I won't know how much till it is on the scales.
The car has had a variety of motors... of the current record holders... the J motor, Kawasaki ZX-7... the I motors, Kawasaki ZX-10, Suzuki GSXR 1000 and Busa... H motors, Kawasaki ZX-11 and Suzuki Busa... the G motor, Suzuki Busa...
But we did not discriminate... it also had a Honda 750 Interceptor motor originally that held multiple records
I was asked the other day if I thought this one would be faster than the old one... I just hope it is as fast
