There's a 200+whp thread floating around here somewhere. Search for it and give it a reading then find build threads for members with a lot of horsepower and you might find some good reading. I know there was a guy on here who had 500+whp but then got sick of replacing axles and other suspension parts so he just gave up and I think sold it and hasn't been heard from on here since.
