Know anything about NO2?

[HXMan]

Ok I know that under WOT, modern cars go into open loop mode, and the ECU injects fuel based on a predetermined map.

Now, I do also know that most cars(well hondas) run a little rich when at WOT.

My question is, to gain 50 hp any car will need a lot more fuel........do the factory WOT fuel maps actually allow for that much wiggle room? Logically it seems a 50+ hp gain should be too much for a stock fuel system.

Or does the ECU notice the A/F ratio leaning out under WOT with nitrous, and injects more fuel?

I am asking these questions cuz I am doing a head swap, and may be hookin up a NOS kit this summer.

i would explain it all, but just go to
www.zex.com
or www.venom-performance.com
or call em and have them tell you the ideal setup

but they both work off the comp, so they r 100% safe for you... and they both kickass:licker:

Just to continue to peak your interest in nitrous, here's a report from my buddy that helped with with my JRSC install and bunch of other stuff.

He's got an ODB1 Civic hatch with a JDM B16A, ITR head using the JDM B16A cams, stock internals, an intake, MSD ignition, NGK racing plugs, a distributor trick (he doesn't tell me everything), 50 shot of nitrous, ACT racing clutch, and 3" diameter exhaust plumbing leading into a Ractive 3" exhaust. I believe that's about all for the mods.

Running using slicks with 10 psi of pressure in each tire up front and 109 octane racing fuel, he pulled a 12.6 in the 1320 last weekend!! That blows many JRSC'd cars (like mine) away by a good second. Just goes to show you don't need to go crazy spending money to get your car faster than sin (oh, by the way, he's also an outstanding driver, very experienced in the 1320).

Sweet dreams boss!

but I will be happy with my b16 for a while, my fundage is now at all time lows.......its all good though. :flash:

[JD@af]

Gotcha. Perhaps for future planning. Just focus on working with what you got. B16A!!!

By the way, saw that picture of your car in your "I might be a hybrid" thread. Ride's looking pretty tight dude.

I know the ZEX kit, when you activate the NOS... goes into open loop mode and it dumps as much fuel as the factory system can provide, into the chambers. a small 50 shot is Generally considered to be "safe".

Basically there is two types of NOS systems. You can have a wet systems wich injects the additional fuel throught the Nitrouse nozzle along with Nitrous. That's where you get the additional fuel for NOS. The other type of system is a dry manifold. In a dry system you inject additonal fuel through ur injectors. The extra fuel come from the higher fuel pressure that is raised by nitrouse system adjusting the vacum on the fuel pressure regulator.

Both systems work great however if you are planning on running a lot of NOS 60 shot or bigger I would recomend a wet system, prefferably a plate system.

JD are you talking about Henry. If it is tell him "what's up" I am one of garry's friends.

the stock fuel systems are quite capable of fueling a moderate nitrous setup. there is plenty of leaway from the factory built into the system. if it ran at max flow in stock form, there would be too much stress.
you'll be fine with a 50 shot.

i've ridden in a GTi vr6 w/ 100 shot, 'zorst, intake, springs. It ran a 12.8 1/4 hella fast. I know it's a v6, but VWs (especially vr6) are tanks compared to Hondas, they hold almost 7 qts of oil for crying out loud. I bet the same setup in a HONDA would be way faster. power to weight, feelin' it.

[quickcivic]

if a VR6 ran a 12.8, a stripped civic should run in the 10's!! those VW's are tanks. a friend of mine once likened driving a VR6 corrado to a flying lawn dart.
i think i'm all set with VW's.

[dubolox]

quickcivic you better chill till the next episode... vw's are fast... I don't want to offend anybody, but I'll take on your roach and hang quite nicely. I dont care about your mods, my car is bone stock 170 hp @ the wheels and matching torque... proven on a dyno.

[quickcivic]

what, the crack dyno?? my civic only needs half the power, because it only weighs half as much. you need "170 proven hp" just to move that shrimp boat.:silly2:

oh, and just because your corrado has more torque than my car and my friends car combined doesn't mean anything. honda's were meant to rev, that's where races are won!!

[dubolox]

thats it quickcivic the gloves are off. I'm looking to get set up in a sweet honda for a daily driving can of whoop ass w/ great milage, but my corrado is still in the garage. Tell you what I'll get a custom chip burned w/ a 4000 redline and show you what torque will do. Just get your woodscrews in 'cause i would blow you doors completely off... not to mention that the screws would also act as a safety device because when i blow by you you'll think you are stopped, you might try to get out at 60 thinking you're stopped and hurt yourself.

[quickcivic]

why did you have gloves on in the first place? is it cold where you are? anyways, i don't want to race that heap you own, besides, woodscrews would just ruin my new paint job.

you probably couldn't even afford the fuel it would take to race me. what does that VW get for mileage anyway? go play in traffic!

[megadragoon]

quickcivic believe it or not, VWs are no joke. Give me a little time and I'll roast some civic too.
