95 Stang - Nitrous Install Questions

[sore]

I have a 95 mustang 5 speed with 75K miles, & the following mods:

Edelbrock intake
underdrive pulleys
70 mm TB
cold air intake
smog pump delete
exhaust (from the factory manifolds back)
Alum. Drive shaft
4.10 gears
Boxed control arms
Holley 155 fuel pump

I plan to install the NOS super power shot (wet) kit that was on my non-EFI chevelle.

I plan to purchase a soft plume nozzle and install it in my CAI.
Is my fuel pump (Holley 155) capable of handling 100 shot?
Do I need an adjustable fuel pressure regulator?
Where should I set my timing? Total timing??
What spark plug should I use?
Is a fuel pressure safety switch needed?
Is any ignition upgrade necessary?
Any computer modifications need?

Yes, I did search old forums, but didn't find answers to all of my questions.

Also, I will have a bottle heater, and will run a wot switch.






Thanks!

The fuel pump is probably ok, but you are definately pushing it.
It is not a good idea to spray a wet kit into the CAI. It is a much better idea to spray it somewhere behind the throttle blade. If you have a converter elbow, that is a good place to screw it in. If not, just drill a hole in the intake just behind the throttle body.
A fuel pressure safety switch will not really do much for you. Those are mainly for dry kits. If you can get that fuel pressure safety switch dialed in at 40psi or so, then it will help. The best safety device I can recommend is a fuel pressure gauge. If you see the fuel pressure start to drop on the bottle, that means you have exceeded the capacity of the fuel pump.
An adjustable fpr is not really going to make any difference for the nitrous. You don't need that any more than you do n/a. You can adjust fuel with the fuel jet.
Set the base timing at 8 to be safe on 100 shot for starters, and advance from there.
Stock non platinum plugs should be fine. Gap them down to about .040" for starters. If you go above a 100 shot, switch to a spark plug one heat range cooler. If the engine suddenly starts losing power at high rpm, that means you are blowing out the spark, and you need to reduce the gap on the plugs.

Isn't the stock pump 110??


Thanks for the info!

Yes, stock is a 110.

Don't forget to install a window switch. You don't want to run a wet kit below 2500-3000 rpms because you'll be more susceptible for a nitrous backfire b/c of fuel puddling in the intake (i think that's why). Also it allows you to shut the juice off before you hit the rev limiter. I run an MSD rpm window switch. It's great cause you can launch on motor and the juice will kick in at around 3 grand.

I also run a window switch. It's a great ad on for a nitrous kit, but I ran for years without it and never had a problem. I wouldn't say it's absolutely necessary.

What is the rev. limiter set at??


thanks,

Factory is like 6000rpms, and it pulls fuel. So you want to avoid that like the plague.

You don't need a window switch for a dry kit but it's highly recommended for a wet kit. Need enough air velocity to keep the fuel suspended in the intake tract.
