I have a 98 with a motorcraft npi replacement motor with just under 20,000 on the clock (wish they'd have went pi). I have a mac cai, 4.10s, pro 5.0 short throw, hypertech power programmer, and steeda underdrives. I ran 14.91 at the track right after I bought it without the short throw and haven't been back yet. Could it handle a 75 to 100 shot of nitrous safely without a tune? Would I need to change injectors? If it can, what kit should I buy and what should my et be in the 1/4 mile. Also, how much is it to fill a 10 # bottle and how many 1/4 miles can u run on one 10# bottle.
