i'm doing a zex system with a 50 wet shot, but was wondering how i high i can go, or if dry is better. I saw a video of a 99 mustang GT supercharged with a 125 wet shot. He was racing a 96 C5 vette when the stangmessed his engine up bad. I'm not sure what happened, but there was oil all over the engine. So thats why im asking whats safe. Also my engine is all stock except for intake.

here's the video too

Wet shot is definately safer. I wouldn't go more than a 75 shot. One thing I would do is use a separate tank for the wet shot using racing fuel so your computer won't go ape **** with timing. Your computer can retard timing up to 3 degrees so it's 1 degree for every 50 hp but with higher octane, it'll be a smoother transition. Don't use platnum plugs because the platnum coating can come off. Use either copper or Iridium plugs.
You do have a chance of spinning a bearing with the sudden shock. What prolly happened was the oil wasn't maintained on the Mustang. The rings have to be shaved a tad bit more than a regular motor because they get hotter and expand more when using a supercharger or nitrous. When nitrous is used, there is more "blow by" (substances from the combustion chamber gets into the crankcase) therefore diluting the oil and could have surged the oil pressure. If the motor didn't have an enlarged gap, it could've fried the piston rings also. If the PCV valve can't extract the extra pressure, then it tends to blow out gaskets. They could have blown the intake manifold with too much boost and then a backfire with nitrous due to improper timing. It could have just had a bad gasket to begin with but those are problems you are looking at.

I don't know much about the dry systems but the Corvette boys are real sharp on em. A small shot (125) should be fine with your stock setup. http://corvetteforum.com/

Don't use platnum plugs because the platnum coating can come off. Use either copper or Iridium plugs. He is exactly right.... one more thing you might want to pay attention to is... While tuning some vehicles, I have noticed misfires on certain cylinders due to the spark plugs not being able to disperse heat quick enough. One thing you might consider is calling the maker of the kit and asking them what heat range plug you should be using for this product as I am certain they will have experienced the same problem. NoS is GREAT for this and has an awesome rep for customer service.

too much for a stock LT1

I'd go with a 100 shot for a stock motor, and that's pushing it. 75 is what I'd run normally. Again NO PLATNUM PLUGS!!!

NGK TR6's FTW...but thats for a 3.8, so it might be diff. for a V8...not sure

:Dtoo much for a stock lt1............ive been running mine for 2 years now with 150 shot,and im going to175! all stock 83,000 miles and never any problems. just gotta know what your doing:)
