Might want to have a tuner look over it and log it on the street for piece of mind. AFR seems good at WOT. He will be able to tell how much timing the car has, if it is detonating at WOT, etc. Sounds like a nice car!

You need to provide a lot more info if you want a decent HP guess. How much boost? Stock NPI motor?

If the car is still the stock NPI motor running the basic 8psi (or so), I'd say your pushing around 330-350rwhp.

Yes stock npi motor... and boost im not to.sure i believe the belt is slipping.... pulls strong still but only shows a max of 3-4 psi.... belt looks a little worn so i have another on the way.... any opinion on the injectors?

 

[Winters98GT]

Why are you jumping to injectors right away? AFR is rich under boost. Not sure that you need them if your FP is good and the car is staying rich. Again, log the car, and a tuner can see what duty cycle they are at. You need to get the car to a tuner, asking people on the net on what you need with little info isn't going to provide you with near the info as simply logging the car will. This will also show belt slippage, etc.

Just asking simple questions for a little more knowlege as to what i have and ppls opinion.... i am unsure of the where the air fuel ratio needs to be...i have owned many stangs but none that where charged so any "POSITIVE" insight would be appreciated.... but yes the car will see a tuner soon.... thanks

Since you're so worried about the injectors, what color are they?

Honestly im not sure ill look at them tom. What are some other mods yall believe would benefit this car? Not looking to spend to much money but would like to see 300 rwhp out of it..... i know the pi intake swap wouldlike benefit it and a smaller pulley... opinions?

Best "bang for the buck" in your case would be a PI swap. The PI motors are 13+ years old so they are everywhere. Finding the parts used and at a good price shouldn't be a problem.
