I have as above a project, AUTO tranny planning on keeping it auto to make 500+ horse WITHOUT internal work, what is the cheapest way to reach closest to that 500HP but most efficient way of doing it. Looking for 50/50 quality versus quantity. Any help on where I should start would be great thanks. I'm also new to this so whatever you have as far as advice, please don't google it then answer, please answer out of personal experience LOL. Waiting on a great response thanks again.
Your not sniffing 500rwhp without swapping out internals. You'll do good to hit 400 before your motor pops. The auto tranny is fine if its upgraded with a VB upgrade, sprags and clutch packs. they have been able to hold and sustain around 550-600rwhp after being upgraded. Some have gotten higher but 550 really seems to be the safe number.
If you want 500+rwhp you need internals, headgasket, tranny upgrade and most likely some headwork and new cams. That's if you want the car to have any reliability to it.
