Re: Zex Nitrous install, with detailed step by step pics
I got 257 HP to the wheel, reading right of the Dynojet machine. Remember that is more than the SRT6 has to the rear wheel. But you are right its low. When I had just the one shot of 75 HP I used an aggressive ECU tune (a little lean with the knock sensor on). To add more nitrous I had to back that ECU down quite a ways to keep the knock sensor off. Here is the link to my shot of 75 HP dyno at 238 HP to the wheel. (http://www.paulscrossfire.com/performanceideas.htm ) In conclusion when I added the shot of 50 to the shot of 75 I lost major power on the ECU tuning, to come out at the end of the 2 stage upgrade with a gain of 19 HP to the wheel. But I'm also running a lot saver now, a little rich instead of a little lean which is a good thing with nitrous and no knock sensor. So I don't recommend more than a shot of 75 HP! Unless to like to throw your pay checks down the drain. My last quarter mile was 14 months ago, and I got 13.7 now I got to go try it again and see. It would be great to see a 12.9 but who knows?
