NOS Advise, Help me Spray for Cheap!

[Rickyll7]

I want to start spraying but dont know a thing about it.

1. what is the biggest shot I can safely do with my setup?

2. what is the cheapest kit that is still safe?

3. is there a system that is backfire proof? (i like my pi intake)

4. i would also like to have it work between say 2700 - 5800 rpm is this called a window switch?

5. can i have it set up in stages for different gears? how does that work?

6. what gears should i run with this setup, 3.73, 4.10?

7. Will i need to upgrade the fuel pump? i have a 98, can i just install an inline to suplement the stocker? what about fuel injectors?

8. I basicaly want to know what is the minimum that i need to be safe, cheaper is better if its still safe!

THANKS! :SNSign:

I am no N2O expert but if you are worried about your intake the only true safe system is direct port. I would only spray a 75 dry shot, a 100 wet shot and 150 direct port. Wet shot is probably the best choice if you are worried about cost they run about $700 on average with no fuel upgrades needed. Dry shot is alittle less but you will need some fuel upgrades. Direct port runs about $1200 to $1400.

Thanks, keep it coming!
Does anyone know what this will do to my torque and horsepower curves respectively? I currently have
291.7 rwhp @ 5227
343.2 rwtq @ 3748
both numbers are corrected and taken from a mustang dyno

1. On a stock bottom end I wouldnt go above a 125 shot wet or dry. I would go with a wet shot.

2. There are a variety of kits out there with varying prices. I feel direct port is overkill on a stock bottom end as from I have seen engines start letting go at 150 which is right where puddling issues also start. NX, ZeX, NOS all make good kits.

3. No. Backfires from what I have seen are measured in how much restraint the user shows. Example: Nitrous burnouts are high risk.

4. Correct that is a window switch and is a very good idea.

5. Yes you can get multistage systems or you can get progressive nirtous controllers. Multi-stages use multiple 'pills' which vary the amount of spray. For example: None in first -> 50 in second -> 100 in third. Progressive controllers are measured in time and are fluid I beleive but you can read up on that.

6. I wouldnt go larger than 3.73's. Even with DR's I have to feather it off the launch. The instant TRQ is amazing and quite addictive.

7. For below a 125 shot I am not sure its completely necessary. I have dynoed mine 3 times and havnt seen it lean out yet even on a 1100psi pull. That being said you cant really be too safe and fuel pumps arent that expensive.

8. You need one step colder plugs. Always run premium fuel. Tune is a good idea however I am running stock timing and fuel with no issues. Maintain constant bottle pressure. GET IT DYNOED TO ENSURE PROPER A/F.

(And you may want to upgrade your floorpans) <--joke

I would guess you will see ~525 TRQ. Which of course is the only number that matters.

where can i get multistage or progressive systems?

where can i get multistage or progressive systems?

A lot of people have recommended the MSD window switch. You can buy it at summit racing.

 

[Rickyll7]

so i think im going to go with a 100 wet shot.

what is the best kit for the money?

what are the differences between the brands?

thanks everyone

Be careful with the nitrous man, respect the power...

I dig this kit alot Nitrous Express's new Ford 4.6L 2V plate system.

All you really need then would be.
1.MSD Digital window switch
2.NX Bottle heater
3.wide open throttle switch
4.Electric bottle opener (option)
5.Purge/blowdown
6.NGK TR6's (colder plugs)
7.Fuel pump (if you plan on spraying 100 shot or more) Walbro 255.
8.Dyno tune and a wideband dyno run to see where you are.
9.You can run up to 150hp shot on your stock bottom end.
10.Detonation will kill your engine the fastest!
