My n2o set up consists of a dry shot through the tip of air filter, then a NOS plate behind the throttle body. I have both kits running off one bottle and they are controlled by a dynotune 2 stage window switch. I did glance at the fuel a bit and with 10.0 afr the fuel pressure was at 48 psi at the end of the run. I'm on a single walboro intank and stock fuel rails with ls6 intake. One thing I learned is good bottle pressure of 1100 psi or higher makes a world of difference. On the first hit the mph was 121, but next pass with lower bottle pressure it only hit 114 mph. I replaced the bottle and mph went back up to 121, then down again on next pass. I wouldn't have figured that out if they had not let me run it for four passes.

the reason i asked about fuel pressure is last time i ran mine the fuel pressure dropped like that and my injectors were not getting enough fuel. the n2o was just using it all and my times really suffered. i dropped .7 with a 75 shot and then only dropped .9 with a 150 shot
i usually run my bottle around 1000. SAR is pretty lax on fast street cars and trucks. especially if your out there with someof the local shops. I was there one nite and there was a car running 9s and the guy only had a helmet.
