I think it's because when you use a dry shot, you're relying on the injectors to supply the added fuel, making your injectors work harder. If you make them work too hard (injector duty cycle) you won't get enough fuel, go lean, and BOOM! Increasing the timing and making your injectors work harder can increase the likeliness of detonation.

 

Yeah, I know about that. But plenty of people spray 125hp and more on these trucks....and it isn't uncommon for some to spray up to 200 DRY on the F-bodies, although they usually have upgraded injectors in those cases. I just thought that with the 100 octane fuel (I run 94 octane usually all of the time, we have it at Sunoco for about a nickle more per gallon then 93) I plan on running and that little of a shot (75-100 at most, probrobally 75) I would be OK as far as detonation goes. And not that I would want to rely on it, but won't the computer knock the timing back if and when it senses detonation or knock? I see what you were saying tho, when he said the only thing that worried him was the dry shot, he meant as opposed to a wet kit.

 

When I first put nitrous on my truck I was running a 100 dry on the Hypertech 93 tunning with no problems. The 93 tunning only advances your timing 4* across the board. Since our stock timing is pretty low to start with, you should have no problems spraying on that as long as you have good 93oct gas and you aren't currently running on the lean side. Although I would recomend hooking up a scan tool to check things out first. fyi the 87 tune is +2* across the board.

 

Thanks for the info on the Hypertech and timing. Thats kinda what I was hoping to find out. I started a new thread for the pics I took.
