So what would be the 'safest' shot to use on stock motor? Something really small?
The size of the shot really doesn't have anything to do with it.
It's the knowledge of the user.Mike is correct the dreaded puddling
and a nitrous backfire is what will hurt your engine.You can stop
fuel puddling by not spraying under 3K prm's.To avoid a nitrous backfire
you can retard your timing by a timing adjuster or handheld programer
before you go emptying bottles.The rule of thumb is retard 2* for every
50 shot sprayed so, if you were useing a 100 shot you would retard your
timing 4* to avoid detonation and hurting your engine.I always recommend
a window switch to be safe.Also if you plan on going with a 100 shot or more
you need to upgrade to a bigger fuel pump.On a stock 4.6L engine I wouldn't
spray more than a 150 shot to be honest.The safest way to go is getting a
tune before you start to spray.I had a H/C/I 92 GT and I ran a NX 75 shot for
three years and I never had a problem because I had a tune and I am a very
knowledgeable nitrous user.Since you have a 4.6L 2V their are two kits I would consider the new plate kits from Nitrous Express and NOS's NOSzzle kit
they would be idea for your car.I think direct port is the best also Mike.
