Naughty33W Posted November 15, 2009 Report Share Posted November 15, 2009 Good point, I was running a MSD RPM window switch from 3500 to 5900 rpm to ensure that nitrous would not spray during the shift. that works , personally i'm more of a push button guy , i'd rather have 100% control myself , that way the only thing that can fail is me hahaha Link to comment Share on other sites More sharing options...
volvo940tuner Posted November 16, 2009 Report Share Posted November 16, 2009 I was told by a ZEX representative that a dry kit is ideal for turbo cars. They said that the one nozzle, installed before the TB, only sprays under WOT if the system is active. If you run a safe size jet (20-50 shot), you really aren't risking much. Eh?

Depends on if your injectors can handle the extra fuel demand. Link to comment Share on other sites More sharing options...
L8 APEKS Posted November 16, 2009 Report Share Posted November 16, 2009 OP...you'll see more power with the ignition upgrade. Period. Do it. Until then...reduce the gap on your plugs to .26 or so. Link to comment Share on other sites More sharing options...
Naughty33W Posted November 16, 2009 Report Share Posted November 16, 2009 the coolest setup that i've seen , which is growing in popularity , is to mount the nozzle ON the turbo , so that when it sprays it helps spin the turbo , this is a drag car setup tho Link to comment Share on other sites More sharing options...
550 Posted November 16, 2009 Report Share Posted November 16, 2009 How does a nitrous jet mounted on a turbo help spin it? I mean, maybe it helps cool it down, but I'm missing it. Also I don't know about dry shotting, I believe if you run a dry shot you should have the fueling to support that, unless you can tune your car I don't know if it is a good idea. This is all with limited knowledge, but from what I understand wet shot is safer as you run a less chance of going lean. Link to comment Share on other sites More sharing options...
Naughty33W Posted November 17, 2009 Report Share Posted November 17, 2009 it appears that they are mounting the nozzle aimed at the wheel , dunno if its actually effective or not , its just something i've seen Link to comment Share on other sites More sharing options...
550 Posted November 17, 2009 Report Share Posted November 17, 2009 I think the reason for that is to cool the turbo down. I can't see the spray really doing much to help the turbo spin. But I don't claim to be an expert either. The cooling properties of nitrous, obviously, are a HUGE help to turbo charged/supercharged vehicles. I have a friend who claims that his Camry, when supercharged, would see beyond a second decrease in qtr. mile times with a 70 shot. It was non-intercooled and he was running 15psi I believe. To get back on topic, I think that when the OP gets everything running correctly, will see the same kinds of "boosts" due to cooling. (Adding to the benefit of nitrous in general) Link to comment Share on other sites More sharing options...
c_long20 Posted November 17, 2009 Author Report Share Posted November 17, 2009 I dont see the point in trying to cool at the turbo when the nitrous cools down combustion temps in the comb chamber. I also dont think its a good idea to fill all those hoses and intercooler with nitrous. If you get a backfire through the intake it could make a mess. The fogger in the intake is more exact and has less room for error. IMO The dry system works but relies on the ecm and injectors to fatten up the mix. A wet system will give a more reliable source of fuel income, makes it safer. Got a MSD 6al box today, and odered a better assortment of nitrous jets. Hopefully we'll get her running better soon :D Link to comment Share on other sites More sharing options...

This is all with limited knowledge, but from what I understand wet shot is safer as you run a less chance of going lean. Both dry and wet shots add extra fuel. One would be stupid to force oxygen into your engine without pairing it up with the appropriate amount of fuel. Wet shots add the fuel by tapping directly off of the fuel feed, then supplying fuel through an additional solenoid and nozzle. A dry shot delivers the extra fuel through the factory fuel injectors. "Dry shot fuel" can be added via ecu programming or by bumping up the fuel pressure at the regulator (and maybe a few other ways). Link to comment Share on other sites More sharing options...
550 Posted November 17, 2009 Report Share Posted November 17, 2009 But with a dry shot you need to add the fuel yourself with programming, right? (Something that you need to "do"). I mean I know nitrous allows you to burn more fuel efficiently so I know extra fuel is commin from somewhere. Wet is more of an add on, and dry is more of a "tuned" option, the way I look at it.

It depends on the car, some manufacturers have special bolt on fuel regulator add on devices which bump up fuel pressure only when the nitrous is sprayed. Those systems use the nitrous line pressure and convert it into the right amount of pressure needed to bump up the fuel pressure on the regulator, no ecu programming needed. Its possible you can adapt the system to any car, but my experience only lies with wet shot systems. Link to comment Share on other sites More sharing options...
