Ok the cats out the bag!!im going supercharged .its a 3800 gm m90.i need lots of help as im a nos guy.for starters my list of mods is in my signature.the guy im buying it from ran it on a stock tuned motor at 3psi.first question is what is the "safe" limit to run boost at?i know it is not ideal but i have a wide band O2 and will be doing tuning very soon.i also will be trying to have my company make a new lower intake mounting bracket on the cnc machine and have it taped for nos/water meth injectors/spray bars.i will also be getting a p+p unit from 3800 performance and stepping down on the pulley to try and run 8-10psi.what size injectors should i run for that?which fuel pump should i run?any suggestions on tuning?i was going to go mega squirt but i see sct has a new chip out,any suggestions?

If your eating belts or squeaking you have a alignment problem or bad bearing.its not the belt.gates are said to be better for grip

Well.. I don't think I have an alignment issue as I went out a few days ago and checked to ensure everything. Also had it checked out by a ford friend of mine and he tested, no issues. I have 3 spare gates belts just in the back in case something happens to the gatorback. From the looks of it I run a shorter belt then both of you, as for now the gatorback has not squeaked after about 2 weeks of daily driving. I am awaiting a tru boost and matching wideband to see if I can't make a video soon. I just can't find a local dyno (without having to go out 25 miles). Do you or Don, run the stock idler pulley?

Love the sniff of enjoyment as you pedal through the streets. I know that feeling and its a great one. I am just baffled how loud it must be in person, if you pulled up next to me I honestly think I wouldn't be able to tell if you had a v8 or v6. Definitely one of the most beefiest ohv's I have ever heard.
