NOS on a 98 Cobra?

I had a Zex kit jetted at 75hp, I went from 13.6 to 12.97 (103mph to 109mph).

I lost my engine, btw, don't know if it was the N20 or not though (spun a bearing)

you can go a 100 shot safe..............as long as your not sprayin everytime you pull up next to an ss or a vette. Keep it minimal and your pistons will thank you. As a rule of thumb your supposedly allowed 25 hp a cylinder on a stock cobra with an additional fuel pump and step colder plugs. If your go over a 125 shot i would consider an aditional pump. Oh yeah just read your plugs time to time they will tell you alot more than most people think.

Honestly i don't see the 96-01 4v handling nitrous. They are always running funny and blow something in the short block. I'm not even going to bother putting it on till i get my built block.
