Sorry,.........but I beg to differ! The dry kit (especially if it's a NOS brand) is MUCH safer than any wet system on the market!
Over the last 6 years, I ran a NOS 150 shot on my Mustang and NEVER had a detonation or back-fire at all. All in all, I'd say I ran over 4000lbs. of juice through my STOCK 302 with no adverse affects!
There is a few things that HAVE to be addressed though!
#1 - Get an adjustable Fuel Pres. Regulator
#2 - Get a MSD6, 6AL or Equivilant
#3 - Make sure you have a bigger fuel pump! I recomend an external type!
#4 - If you go with a 150 shot, go to at least 1 step colder plug
#5 - Make sure plug wires are top notch
#6 - Run the best Fuel Possible 93+ with about 9-10 deg. timing,.........114 with about 12-14 deg.
#7 - Don't get gready and think you can go above a 150 shot,...........you'll only be sorry in the end!
Use these items as a rule of thumb,......and you'll be fine!
