My family actually has 3 Fords all with the same 4.6 SOHC engine. One of then had 2 have 2 replaced, the other had 1 replaced. Mine doesnt have them so none have gone bad.... But getting those 3 COPS from the dealer was expensive even with an employee discount.
Actually, the dyno was not generous because those are the exact number Kenne Bell says they should be. Plus, my car was tuned by one of the best Boosted Mustang tuners in the country, Greg@RacersEdgeTuning. The tune makes all the difference. I am also running a ver conservative tune with only 12 degrees of timing. My tuner makes magic happen,
Between me, my granddad, grandma, and dad, we have: 4 Mustangs (2 Mach 1s, 01 Gt, and my 98 GT), 3 5.4s (my dad's E250, grandma's 4x4 150, and her Lightning), and my grandma had an 01 Crown Vic until last year. Between all of them and the years we've had them, we've got WELL over half a million miles, and not one issue with a single COP. I have several good friends that have 4.6 Mustangs, and have had them for quite some time, that haven't a single issue with COPs.
I'm not saying they never give trouble. You said you have family that's had issues with them. I have one friend that has an Expedition that chews through those things like crazy. But that's the exception, not the rule. The huge huge HUGE majority of people never have a single problem with them. And like I said,
www.car-part.com has them listed all over everywhere for $20-$30.
And I'm sorry. But "good tuning" has nothing to do with how much power your car makes at WOT. It is EXTREMELY easy to tune WOT on most cars. You simply add/remove fuel across certain RPM ranges until you get the AFR you want, and then adjust the timing to a safe level that makes power. That's it.
Of course, there's more to it, like setting up the spark and fuel tables to do certain things in certain situations (such as pulling timing when the temp goes up), or like adjusting the converter lockup schedule on an auto car, or the part throttle/load/spark settings, etc. But none of that has anything to do with WOT power. AFR and timing. That's it.
And there's no way you're making the same RWHP as an intake/exhaust/tune 4-valve 03/04 Cobra. They are running roughly the same boost level, except with 4-valve heads that flow 233 CFM (as opposed to 177 on the PIs), and a couple degrees more timing on a tuned car.
I would love to see Will's car vs Handz car, Im sure the car w/o the KB on it would win.
Nope. No way possible. I'm only making 336 rwhp (over 70 rwhp less). AND a lot less torque. AND I have a stock, auto transmission. AND it's a super-duper inefficient roots-style Eaton. AND it's non-intercooled. AND I'm spraying meth....which will probably run out at some random time when I'm least expecting it to.
So...no. I stand no chance.
at the track. I've seen procharged mustang gts running high 11s all day long with a good driver.
