nitrous help

[mistergee]

i recently installed a wet nitrous kit on my 03, i sprayed the car with a 100 shot of venom and after a couple sec, my car died, the boost-a-pump fuse blew, so i replaced it with a a 25a fuse, and sprayed again this time the fuel pump fuse went out. does any one have a clue on whats going on? could i be maxing out my pumps?
:shrug:

Where you pulling power from for your nitrous?

You should have plenty of fuel...it seems to be a voltage issue. 2004silvercobra has a good suggestion.

Check your wiring and make sure you are grounded correctly. Also make sure your alternator is up to snuff.

You definitely don't have enough fuel and if you keep doing what your doing your going to blow the motor. With stock pumps and injectors and a bap on just a 75 shot I hit almost 100% duty cycle on the pumps and had a nasty lean spike at the initial hit. Do not spray more then a 50 without at least upgrading your pumps.

Not to ruin his thread but this interests me. I have the same set up without the nitrous, so if he (or I) were to have upgraded pumps...60lb injectors and the proper tune, the NOS would not be a problem with the mileage? He has 150k thats a lot on the stock internals. I have 90k and was hesitant to do this.

You are def maxing out that setup and also wiring is def an issue for you to keep blowing the fusses

Yea I only did it those two times, I'll go with a 75 shot see what happens

It's a WET kit people.

You most likely have a WIRING problem.

Bullshit. What do you think a BAP does? If anything maybe upgrade the injectors... Does OP even have a nitrous tune?

Are you running a 40amp BAP?:shrug:

With a 25 amp fuse?:shrug:

 

[346CamaroSS]

Nice catch Jimmy.

I agree its not fuel related and is a wiring issue..

A bap works great with good pumps like the gt40 but the cobra pumps even with a bap and good wiring do not flow enough to handle a the amount of fuel a wet kit takes this is way more taxing then a 550rwhp 2.2 or 2.3 twin screw blower...even if the HP difference isn't that great. I'm not some noob speaking out of my ass but from real world experience..this wasn't my friends cousins car, a YouTube video, or some shit I heard at the cars and coffee meet. But by all means you ppl that believe what kb publishes about their bap tell me I'm wrong and let this guy grenade his engine.

You would be golden with that setup...I would however recommend a compression test first just to make sure the engine is still healthy..also you might want a 1 degree colder spark plug...one other commonly overlooked side effect of spray is decreased oil life...but for the money when done properly there is no better horsepower per dollar mod.

I definitely appreciate the input. Rather than spend $4k on a twin screw, we can spend less than $700 for 100+ shot of NOS

Thanks again :beer:

I have an NX wet kit and am having my tuner install a SAFE system...i will post up some numbers and results around SEPT 10th when its ready....give you an idea of what it can/cant do.

No nitrous tune yet, I was told I didn't need one for a 100 shot I was thinking tha same about the injectors

Yes, it first had a 20amp fuse I'll toss in a 40 amp
