N2O with Stock engine?

[NKPlus]

I am trying to decide if I should go with S/C or N2O, I know what modifications I need for the S/C but for N2O is the same? I was wondering can I just slap a 75 hp N2O on a stock engine with a stage 3 slutch?

No. You would need copper plugs, atleast 2 ranges colder then stock. Aside from that it is really a plug and play mod.

Where can I find copper plugs?

I ran a 100hp ZEX Dry shot on my last 1990 SHO with no problems. I only dropped one heat range on the copper plugs but I did switch to cooper plugs (available at any parts store), also replaced the fuel filter and ran a bottle of Berrymans B12 Chemtool through the gas tank after replacing the fuel filter.

Once the maintaionce was up to par I had 0 issues with nitrous.

Your 1990 SHO took 100hp with no problems with a stock engine? Thats . Also any brand you prefer on spark plugs?

Autolite copper 3923. Love those plugs and they are cheap. Stick to them and you'll be fine. Alternately you can get some autolite copper 3922 which are another degree colder and will resist detonation more.

The one Nitrous equipped SHO I rode in had a LPM burned so when the Nitrous was armed timing was taken out of the engine to help prevent detonation.

I also have 100hp jettings for my Zex kit. Ran it through a couple times with no apparent issues.

How do you take the timing out of the engine? Wouldn't you want to leave it in there? I hate running my car with missing pieces.

run a 75 shot all day on my daily SHO with 170k.

Make sure you get all the maintanance done.

Bigger fuel pump and I run the denso spark plugs.

Total cost $500 with used Zex Kit.

178K miles on my stock motor.. mods are in my sig and i run NGK iridium plugs at the factory heat range with a 75hp shot and NO problems.

Besides the fuel pump what other maintanance is there can anyone help?

Run a couple tanks with B12, not just one. You don't want a dirty injector cutting off fuel flow.

cooper plugs are recommended more because they are cheaper (so you can replace them more often) and copper dissipates heat faster than iridium,platinum, etc...

Fancy plugs may work well but so do the cheaper copper plugs.

 

[SHOblime]

Cheap copper plugs are the best spark, period. The advantage of other plugs would be how long they last (25-35k mi for copper, 100k for platinum) not that they create a "better" spark...

 

[nc89sho]

FYI, my iridiums were cheaper than stock.

usual 60k/120k and tighten up oil drippies.

Basically make sure you motor is running like it should.

Pile on the juice!

since this is a NO2 thread my brother is wanting to spray is gutted 89 "super beater" you say a 100 shot will work with no problams but can you go any higher and before you answer keep in mind how the car got its name "super beater" its not pretty but it ran a 14.5 @97mph (open Y-pipe and gutted, that all thats done to it.) last weekend and with some juice he would like to take a lot off of that.

the fordbastards crew had a member blow his motor at 125 shot on stock programming.

I would say thats about it.

Last time I was in the SHO scene I saw Doug @ FPS had a direct injection wet kit set up on his....I know this won't sound right but I coulda swore he said it was a 200hp shot or so. The problem was all in the injection method. Once he mounted the nozzle in each runner the fuel wouldn't puddle and lean out 1 and 3 cyl.

I may need my facts straightened out though...dont quote me unless Doug posts.

Last time I talked to Mark N. I believe he said he ran some jettings that put him over 100HP, but I can't remember if he did it by accident when first learning about nitrous or what the situation was.
