Nitrous Oxide + 10:1 compression ratio = bad combination

not if you properly setup the nitrous

I have a wet Nos setup waiting to be fitted, will be running 15-20 psi and a 50hp shot.

From speaking to people i have heard that wet nos kits are very safe, and can be used many times over without any dramas.

yeah I have a friend up here w/ a viper red mr2. He has the full JDM (ecu and everything) turbo swap. His car is pretty freakin fast. He also put a 40 wet shot on for insurance ;)

He was running 8.7 @ the 1/8 w/ the 40 shot. He just installed 60 shot nossels but hasn't been able to drag it yet b/c the strips up here are down for the winter.

Can you explain, I'm not sure if I dare to install Nitro.

Nitrous Oxide is very hard on your piston rings, connecting rods, head bolts, head gasket, etc... When nitrous oxide is used it greatly increases the amount of heat and pressure in the combustion chambers, which can overstress the metal. If its used on the m42 or any engine, it probably wont hurt the engine the first time, but after a few times it could have negative effects. Here’s something I heard one of my friends say... Babies get bottles, Men get blown.

thats a good one! but who wants to bother blowing an m42? a supercharger or turbo set up costs more then i payed for my 318i!

if you use 50hp shot you dont have to worry , but in moments when you make shot be karefol watch only when rpm nidlle is up to 4000rpm then is save if you make the shot before 4000rpm it has big risk for pistons

many people use 75 even 100hp on 1,8l motor on 10,5 CR but they make ignition timing coretions and don't have problems
