Nitrous Oxide how safe

[stevesLX]

I am looking at picking up a ZEX DRY kit for my 89 LX it is fuel injected. The kit is 75-125 shot. My machinist that I just had do work on my heads and block told me when I got my motor back that all my clearences were very very close or tight. With that being said is it safe for me to use spray w/out blowing anything up.

Just to give you all a little history on my motor. I bought the car back in Nov. it had blow by and a busted main. I had a new main put in ,new bearings, seals, the pistons are still stock ford pistons and the crank is stock. My heads had a 3 angle valve job done and milled, and the block had the deck milled. The catch to the deck on the block is my pistons were coming up .020 out of the hole so being on my tight budget I just had them do a fly cut to my pistons.

I would think that that would have to cut the top of the piston off, not flycut it.

The tight clearances have nothing to do with a power adder. u need to break the motor in NA and let everything seat. once u have a couple thousand miles on it and it consumes no oil, that way u know the rings have seated properly.

Then get the NOS kit and get a custom chip burned. keep the rwhp at or below 450.

Nitrous is as safe as you wanna make it. I run a dry 75 shot on my fox with a stock engine(aside from a Bcam and bolt ons) and the car loves it. This is also on the stock fuel pump. If your gonna run anything more then 75 upgrade your fuel pump. I put in the 100 shot and it was roasting the tires off in 3rd but was running out of fuel up top. Bolt it up and have fun.

nitrous is safe. I personally like a wet kit because it is safer. You are adding the extra fuel you need to give you the proper afr on the spray. Nitrous raises the temp in the cylinder so rings that are very tight are a bad thing since they will expand when spraying.
