Nitrous

[LGAFF]

Never had an interest in running it, but thinking of doing it to my 90. Maybe a 50, 75 or 100 shot. That would put me from a stock 441rwhp to 490-540RWHP...

Lets discuss...systems, issues, etc

NOS used to make a 125 dry kit for the zr-1.

just to say, if the kit says 75 hp or 125 hp, it will be horsepower at the wheels. it will be a real kick in the butt. dry kit is the safest just got to be sure you dont go too lean and hurt your head gaskets. the wet system is dangerous since you can have gas puddle in the intake causing a nitrous explosion. nitrous is risky but it is the best bang for the buck period. you can get a regular 400 rwhp car and put a 125 hp kit and have a animal on your hands. you will need a bottle warmer and also a electronic bottle opener.

GM ran an LT-5 with nitrous, it ran 11.9 @ 123MPH

that should be no problem. nitrous is the big equalizer. i would not mind a 100 horse dry kit as a security booster. since so many cars are boosted now it is only fair to have a nitrous system for those quick bursts. if someone made a safe dry system and i had confidence a good tune could be had for it, I would be all in.

How do you add enrichment on a dry system? What I'm asking is how do you tell the ECM to add a crapload of pulse width to the injectors and to retard timing a couple of degrees? At least the wet systems work- you add hp by leaning them out until it gets touchy.

Lastly, nitrous injection hits hard down low unless you got a multistage setup. The injector flows whatever when you hit the switch and if the engine is spinning slowly at the time, it really fills the cylinders. At 6500 rpm, the system may only add about 50 hp, but at 2500, you'll swear the car has 454 inches.

I think it would be awesome to throw a little shot on my car.

having 16 injectors i think we could only have the nitrous activated when the secondaries are firing. we can also fatten up the fuel curve so it would survive the dry shot. we can have the nitrous only come on after 3500 rpm and a wot. this is the time a good tuner is needed. i would not use more than 100 dry shot just to play it safe. its my experience with nitrous moderation is the key.

Just bought a nitrous kit

Nitrous Oxide Injection System Kit-EFI Wet Zex 82026 w/ Accessories

I believe I need to get a window switch and also need to figure an easy way to retard timing.
