Lance,
I understand. You just never know when a Z06 or Ford GT will pull up next to you at a traffic light, do you? After driving my car for 19 years with a 356 ci engine and never being beat, the new cars have upped the ante. The Z06, Ford GT and Porsche Turbo are turning 0 to 60 in just under 4 seconds. My new 408 engine will put out 433 Hp and 500 Ft Lbs according to the Desktop Dyno program. The Car Test program, with those numbers inserted, predicts a 0 to 60 at 3.48 seconds. I am hoping that will be good enough. If an Enzo or McLaren F1 shows up, oh well!
The Top Shot nitrous set up looks pretty good to me. I have thought of going this way and even tried a 10 pound bottle in my trunk to make sure it will fit. It does, but takes up a LOT of space. You just have to make sure it cannot open up the solenoids unless the throttle is wide open. I would start with the smaller, 75 hp, jet and see how it runs. If you really feel the need, go with the larger jet. It mak be a really good idea to install a lower end girdle to keep the main bearings in place though.
