I actually have a NOS kit I bought a few months back. I was going to throw it on but laterly have wimped out!HA The scary part about NOS is the frist time you spray. It works or blows the motor thats about it. 50/50. All of the feed back I've gotten from the major NOS companys has been postive. The 350Z kit will work on are cars and has the same fuel pressure as ours; so the jetting will work perfect. A 100hp shot will raise the compression of the motor about a full point so, 11.8:1 will be 12.8:1 you can still get away with 93 octane at this compression.

well, 50hp jets will drop about 2/10th off---75hp jet @ .5 SEC AND 100HP most likely @ 1.0 full sec. depending on traction. I'm going to wait until I get hedders and custom mid pipe before tring the kit. Removing the heat away from the motor is very important with NOS. Good exhaust flow will help this. But its coming!!

If you plan on using NOS I really recommend some sort of auxilliary timing control to reduce the chance of detonation. I think one could get away with using a greddy E-manage ultimate to do the work. You would need to cut and splice the wires unless you get an adapter ecu harness. The unit will take control of the timing of the engine only if you modify it otherwise it will leave stock alone. A NOS system is like an on-off switch. When you're not using it you will pretty much run the ecu on full control and the e-manage can be used as a datalogging device. When the NOS is active, the timing can be tailored to the full throttle curve. The engine ecu during full throttle doesn't factor in emissions as a priority and focus is on advancing the timing. If the ecu sees knock it backs down the timing but during NOS, timing has to be detuned so far that the ecu may set off an MIL. The e-manage will send back a false confirmation signal to keep the engine ecu happy while controlling the timing as needed. I too think the engine could handle another 100hp without getting into too much problems. But I would use a dry shot on the intake and an additional fuel injector (also controlled with the e-manage) to squirt additional fuel into the intake stream. IMO, fuel metering control of NOS solenoids are nothing more than a problem waiting to happen if the fuel solenoid sticks.

When I use the horsepower calculator on DragTimes.com to estimate the power that Caymandive's car was making to achieve his 12.844 @ 109.2 with a weight of 3575 lbs, it comes back with 348 HP. When I do the same with his previous run of 13.149 @ 105.75, it comes back with 320 HP. So it seems that it only takes about 30 HP to reduce 1/4 mile times by 0.2 seconds. I would expect the next 30 HP increase (60 total) would improve times by slightly less due to diminishing returns.

This is wild!I just finished installing my NOS kit kinda! I have to order some factory SST pressure fitting for the fuel. This way I can use the factory quick connectors. IF I get these parts in I'll be spraying by this weekend!!!!!!!
