GTS25: It's just a plain ole NX Nitrous Kit. No computer control or anything. RBS30: Whats up man? Long time now see. LOL. The pulls were made on a dynojet which I know typically reads a little higher than some other dynos but when you plug my numbers into a hp formula that takes your 1/4 mile ET, speed, cars weight, and everything it comes out pretty much dead on. JT

Off the bottle it made 445 rwhp 11.8:1 AFR. On a "50" shot it made 515 at like 10.5:1 afr. On the "90" jets it only made 535 but was below 10:1 for the entire pull. Obviously they jet them VERY conservatively. I ended up using the 125 nitrous jet and kept the 90 fuel jet which put me a 11:2 and 595 rwhp. And actually on that pull I had a nitrous leak. After fixing the leak, on the next pull, it was making another 35 hp at 6000 which put it on the track to be about a 630 hp pull. I didn't get to complete it though b/c of a nice backfire. I have been having this backfire problem for the past couple weeks intermittantly. It's something to do with the SDS since it does it on motor as well. It's throwing an rpm error message when it happens. I am off work tomorrow and hopefully will be able to run down the problem and head over to the track. For some reason I have a feeling the 235-60-15 M/T ET street radials aren't going to like the gas too much. LOL. We'll see. JT

Put my Z back on the dyno last night to see what kind of numbers it would make since installing the nitrous. The pull was made on 93 octane fuel, 17 degrees total timing, 11.2:1 AFR. Laid down 595 rwhp (~444 kw). Still on completely stock long block down to the stock headgasket and cams. Keep in mind this is also going through a th350 transmission, which cost me about 40 or so rwhp when I changed from the 5 spd. Anxious to get it back to the track now.....I figure it oughta trap in the 140 range and get in the 9's with some decent traction. JT

Update on the RBZ. Went back on the dyno last night and did some more tuning and sprayed some nitrous to it. Laid down 595 rwhp (~444 kw) on 93 octane. Still internally stock motor.....stock headgasket, cams, and everything. AFR around 11.2:1 JT

Completely stock motor internally T04r sheetmetal intake custom header SDS EFI 20 psi on 93 octane 489 rwhp (364 rwkw) @ 7500 rpm ~11.7:1 a/f Expecting around 600 rwhp with some good gas and more boost. JT
