Re: nitrous 0-60 and 1/4 mile results
Well a 75 shot to the wheels is going to be like 100 to the crank. I agree with Serbstang though that you will still want a tune. It will be safer and you will gain extra HP in the process. I would be cautious with the Zex kit as I believe Zex kits rate their HP at the wheels, so a 100 shot of Zex is more like 125 or 130 of NOS, Nitrous Works, Express, etc. I'm not really sure what it would do, however there is the old rule of thumb that and extra 10HP to the wheels can account for about a tenth of a second especially when the car is stock or close to stock. I would imagine you would gain about 1/2 second off your old E/T, but then again this is a speculation.
