I was just wondering if anyone could estimate my HP on my 6.0 powerstroke. It has ARP headstuds, EGR delete, upgraded lifters and oil pan, S&B cold air intake, 4" straight pipe exhaust, and 150hp SCT tuner. I know it made 325hp and 560ftlbs of tourque stock so I was wondering what it would be about now.

 

Put it on a dyno for a true number.

 

There isn't any place around me that I can do that so I was just wondering if anyone had any estimation

 

In that case....I would add 325 + 150 + 25 for fluff = 500 hp

That's my SWAG anyway...

 

What are you using for lifters? I've read they are a common part number but don't often see anyone mention an upgrade.

 

And deduct 75 for reality and you'd probably be close. The only real booster you have, IMHO, is the SCT and wether your getting the full 150 is debateable with out a dyno.
