Cobra shot.

[360Rocket]

Well, the 360R is gone and I have replaced it with an 04 Cobra. I was throwing a 50 shot at the 360R dry, no tune changes. A Zex kit mounted before the MAF. Now with the Cobra, I was curious as to what size shot would be recommended for the new car SAFELY without changing the tune. I will tune it in the future, but as you know the initial cost of a new whip takes a little to to recover from. Just hate to see the nitrous kit sitting on the work bench. Any advice would be greatly appreciated.

what has been done to the car so far? if it is stock a 50 shot is the biggest i would go without a tune. on my 03 i was running a 2.8 pulley, diablo pred., and mac pro-chamber with a 50 shot. however the stock diablo tune was ultra conservative and the a/f ratio was off the charts rich above 3000 rpm so it was more than safe.

I dont believe off the charts rich is always safe.

Well within reason of course. it was getting way more fuel than needed. diablo creates very conservative tunes leaving plenty of room for variations

Now Zex doesn't use a 50 shot jet, at least not in this dry shot kit I have. What jet "number" and brand would I use to get a 50 shot with this kit?
