NOS Power Shot?

[Hafrod]

I have a brand new NOS Power Shot kit still in the box. Its a pre set 125 shot carb plate system. Can I use parts of this kit on my 87 GN? Maybe buy a fogger nozzle and jets?? 50 shot???I have the basic 12 sec stuff - adj fuel reg and wastegate, bigger fuel pump,K&N, exhaust,etc.(stock turbo,intercooler,downpipe). I bought this kit 6 months ago for a Monte SS I had but sold the car. dry system or wet for GN?

[Hafrod]

How about this idea?? set up a seperate tank(1 gal cell), a universal electric fuel pump and use alky(instead of gas) with the nitrous through a fogger nozzle? I have most of this stuff in my shop but wondering if anyone has tried this

[SlowBlackCar]

How much for the kit ?

[Hafrod]

I don't want to sell the kit, I have a 55 Chevy 2 door Hardtop and a big block 71 Chevelle it can go on!

If you try to use the kits jetting with alky it will be way off. Contact NOS first and ask about what size jets you would need to make it work. A dedicated tank and pump setup is a good idea but for what youre trying to achieve it would be cheaper and easier to just setup the car with a wet kit and use gas.

Just have a short -04 steel braided line made and pull your fuel from the injector rail to supply the fuel solenoid. Your fuel supply needs to be boost referenced so it doesn't go lean as boost climbs.
All you'll need to buy is a fogger nozzle, 2 jets and some lines.
It's as simple as that.

So the solonoid can hold that much fuel pressure? Is a 50 shot about max on a 130000 mile engine?

The nitrous side holds 1000+psi no problem.
The solenoids are built the same... just with different plunger seals.

If you want to maintain proper A/F ratios, you MUST use a boost referenced fuel supply.
I don't think you will be limited so much by the engine mileage, as you will be from running a stock turbo.

what do you guy's think about the nitrous express EFI single nozzle System, no engine modification's Required, work's on stock fuel pump and no timing Retard. Thank's

I am not sure why the stock turbo will put a limit on the nitrous? Unless your just using it to spool a bigger turbo. With a stock turbo you can use it thru the whole run. I have been running nitrous since '86. (Thousands of runs)

On a stock gn with upgrade fuel pump, knock gauge, fuel pressure gauge, street chip, and 75hp jets you can drop and GN running 13.6's to 12.6's and contrary to belief it is quite safe with 1. Proper fuel supply 2. good tune (good spring cleaning) 3. correct timing. I ran my first GN at least 500 runs min. and the check bearings, rods, and pistons with no problems. When you get up to 125 then you need a nitrous chip, colder plugs, really good tune on a stock setup. With 125hp you should be punching into the 11's with proper traction.

Times I have blown head gaskets 1.was strip chip with 125hp nitrous,(greedy) 2. Using funnel jets and could not get jets I need and tried drilling the size I needed, I was off and leaned out.

1st it depends on the hp level, 50hp you could get away with the stock pump but thing you really need:

1.Fuel pressure gauge- you need make sure your fuel pump is keeping up, you can use the stock pump but I would highly recommend upgrading the pump. It takes just a second for the engine to go lean and then you will be replacing headgaskets.

2.Knock gauge- first yellow light and you better be off the nitrous.

3. good tune up

4. street chip, you might even get away with normal boost level

If you go over 50hp you will need to adjust boost level also, 50 will jump about 1-2 lbs, 75 2-3lbs, 125hp 3-4lbs depending on air temperature, turbo, and intercooler.

as you can see in my sig below, my car is running 11.oh's, my car spool's great, just thought i would try the nitrous, but then again i might just turn up the boost and get it on, I should be able to hit some high 10's.

I'd be completely embarassed if I could only muster a mid-12 with a nitrous bottle in the trunk.
Nitrous is often used as a crutch for someone who can't otherwise make a car fast.
I think it's more fun to build and tune without it... then add the nitrous AFTER you have proven the combination you have already goes fast...

Running mid 12's on a stock GN with a small shot and for a beginner is quite respectful.

Back in the mid 80's I was pretty proud to be in the mid 12's with a 50hp shot of nitrous and drag radials. NOT many were running that well. Now we are running 11.4's on a 130,000 mile stock long block with stock turbo, stock intercooler, stock converter, stock tranny, my chip, and all part with 130,000 mles. We probably have less money in the whole setup then you have in your turbo alone.

Actually if you don't have a good tune and using nitrous you will be tearing you motor down after you blow it up.

I don't know of any truly stock GNS (stock turbo, stock intercooler, stock injectors, stock longblock, no alky kit, and stock converter- all of the above, not just one) that are in the 12's on pump gas and if they are Its high 12's at sea level and real cool weather. (Real Life)

Now you put on a upgrade intercooler, upgraded fuel pump,bigger turbo, bigger injectors, stall converter, and maybe alky kit and your in the low 12's, 11's if you got the bigger turbo and running high boost, maybe 10's if you lucky but then your wallet is 100lbs lighter.

OR you can put in an upgraded fuel pump and $300 nitrous kit and run 12's easily, 11's most likely, and 10's if your pushing it for alot less cash.

Both methods do the same thing- you are putting more fuel and oxygen into the cylinder to make more power. One just cost alot less. Don't kid yourself on a turbo motor you need a good tune, it's not as easy as adding a 100hp shot on a NA Big Block.
