Nitrous plate kits?

[86hasel]

So, I've got my 86 monte ss, built th350 w/2800 high stall, 10 bolt posi, and a 9.8 compression 358 making 421 hp on 91 pump gas. But that's nothing mind blOwing. So I was thinking, what about one of thise nitrous plate kits? They're affordable, and seem easy enough to install. When we built the engine everything was replaced with forged components except the crank. How large of a nitrous shot could it handle?

It should be fine on a 150 shot but anything above that is dependent on your ring gaps and how much trust you have in the cast crank. Take that with a grain of salt though, I've seen purpose built nitrous motors pop under spray...
I've heard that the pressure spike the crank sees with a hit of nitrous happens within a window of 30* of crank rotation whereas boost from a turbo or centrifugal supercharger happens over a much larger window of around 180*.

Make sure you have a good fuel system, the last thing you want to do is run the engine lean while spraying. Back off your total timing a few degrees. A colder set of spark plugs doesn't hurt as well. Check your plugs often for little specs of aluminum burned in to the porcelain (spark plug). If you see specs, your running too lean and starting to burn up Pistons, and or are getting a little crazy with your set up.
I like to use a WOT switch as well, this way there is less of a chance of turning it on under part throttle.
Another thing, please don't use a torch to bring bottle pressure up.....I have seen people do this and it's incredibly stupid. 900 PSI ( pounds per square inch) of a oxidizer, plus a flame.....and you have a good recipe for a explosion.

Nitrous is a great way of adding power, as long as you are smart about it.

I have a Zex perimeter plate system that has the capabilities to make 300 horsepower and I built my engine with the intent of possibly using it even though it is set on 100 right now.
I have a separate fuel system on mine and for my system to function I have to flip on the arming switch, the full throttle switch has to be on and I have to be within the range of my window switch and then I can hit the momentary switch on my shifter.
Here is my video of the set up I did for my Monte.
