would it be safe to putt a 100 shot on a lt1 with a 170000 miles

I wouldn't unless I had another engine ready to go when the 170k blows.

If you take all the precautions and your car is in good running condition i dont see why not, maybe start w/ a 75 shot first.

I agree with pancho. I ran a 100 WET shot for a long time on my old engine. It never failed. First, make sure the car is functioning properly. Fix anything that needs repair. Make sure to run a colder plug (Autolite 103, NGK TR56), pull 2* of timing when spraying. Install a fuel pressure, WOT, and Window switches. And it would be a good idea to change your fuel filter.

If you have an A4 the window switch will help save your tranny by turning the spray off before you shift. The WOT and fuel pressure switches are good security in case you get loose and let off the gas it will turn the spray off and help prevent a nitrous backfire. And the Fuel pressure switch will save your engine if you pump fails or you loose fuel pressure for some reason.

2* per 50 hp of nitrous

Is that what they are rating it now? I started with 4* I assume. Its been years since I had the kit on the car. Towards the end I know I wasn't pulling any timing and running 1000-1200 psi bottle pressures. IMO a 100shot is small...

If it makes ya feel better. I sprayed my 200k short block with 150 shot for over 2 years. Never had a problem. I had 255 fuel pump and tr6 plugs. I was still running stock timing also
