No, the stock valvetrain isn't good for anything past redline. Then again your only shopping at one place for your parts. Like I said, at the $1500 mark you should get a upgraded valvetrain with a port job and 3 angled valves. Besides, internet pricing VARIES alot. Have you checked with Esslinger, Alamo, Ford Racing or even contacted your local machine shop? (One pointed at performance) ALL of these other places are GREAT ways to get a good product that works at a good price. After all, FocusSport has to get thier heads done somewhere - why not cut the middleman out?
I am sorry to hear that most of the Focus tuners out there are not getting more than 170hp on thier vehicles.
The SVT focus STARTS at 170hp. The engine is the same other than the head and exhaust on the stock focus. I know alot of guys out there are running more mods than that on thier cars and should be pulling more power from them. But alot of it has to do with how they install them and whether or not the combo is tuned in and burned for thier car by using a dyno. You didn't state if the numbers were WHP or FHP numbers. Another point as well, how many of these guys have rolled thier cars on a dyno to find out what they are really pushing?
