Exclamation F150 Roush Stage 3 +

I bought a 2005 Roush stage 3 supercrew with 445 rear wheel hp. I am happy with its performance but I would like to know how to improve its track time. Some ideas that came to mind are gears, sc pulley, and an e-Fan, but I don't know what brands to get. I would love nothing more then to leave an RT 10 in the dust.

If you have any suggestions please post them.
Links and part #'s would be greatly appreciated.

TENS!!! Damn man... Everyone wants tens. I love those trucks, wish I could have one.

I was suprised to see that it didn't come stock with an e-fan.

look up chickeners.com, lighting force performance or RPM perf.com they can help you with your mods, Did you get the RWHP # from a dyno ?

I know Roush quotes that.

But methinks that actual numbers will be closer to this:

...especially considering the 14-flat/high 13-second quarter mile numbers that I've seen posted.

I just bought the truck and have not had a chance to put it on a dyno nor dyno tune it.

Why is the hp different then what roush says?

This is all just my opinion...but I think it's marketing.

Whipple makes huge claims for their 3V F150 blowers as well, but I haven't seen anything near what they are claiming, either in-person on a dyno or on dyno sheets that I've seen online.

Put it this way: If Roush makes 445 hp to the wheels, then it's making more than 500 hp at the crank. Which is Ford GT territory.

Don't get me wrong, I'm not trying to knock your setup. In fact I think it's a killer truck that I'd love to own. It's just Roush's power claim that I'm a bit skeptical of.

Roush horsepower claims are flywheel horsepower not rear wheel horsepower.

I am taking my truck in a couple of weeks to see whay mine is at the rear. Right now I run a consistant 14.66 @95 MPH with a 2.20 60' time launching in 2nd gear with 20" rims. I have had a best of a 14.57. I am still running the stock tune with MPH limiter in place, but I do have a set of pacesetter long tube headers, high flow cats, x-pipe and DI/DO magnaflow muffler for a custom true dual exhaust. Scheduled for delivery today I have a 2lb lower pully upgrade coming and a xcal1 to copy the Roush tune to send back to Troyer Performance. My main problem on 1/4 ET is traction. I have made a set of traction bars like the Lightning's run but I will still spin the tires through 2nd gear if I start in first. The closest drag radial I can find for tire height is a M & H racemaster in a 390/40/17 it is 29.5 inches tall but requires a 12" wide wheel. Talking with Troyer Performance I should be somewhere in the 380-405 RWHP range after there tune and the pully upgrade. Hope this gives you some info.

How does Roush deal with the fly-by-wire lag? Do they use a direct mechanical route?

Roush still uses the fly-by-wire. To be honest with you I was kinda worried about that when i installed the SC because I had a excal II tune in there which eliminated the lag. After the install if there is any lag after Roush reflashed the PCM I dont see it do to the ungodly throttle response. The only thing I dont like is Roush sets the bypass to kick in at odd times in the upper RPM, and once you let off the throttle the boost bypass kicks in immediatly, so that take a little getting used too. Other than that I have actually gained .5mpg and that is whith a lot of WOT runs.

Thanks huitt24

I know there are program tweeks to reduce the lag, but none that I know of to "eliminate" them. Real good information. 14.66 rivals the stock Lightning. Super impressive time for a very heavy vehicle. Now I wonder how it would run with 4 valve heads, stronger rods, better pistons and some juice?

Roush doesn't claim 445 RWHP. They claim 445 crank HP, or 145HP over stock crank horsepower. The stock truck puts out just a little over 200HP to the crank and the Roushcharge brings them to about the 330HP range at the wheels.

The throttle lag on the F150 is not due to drive by wire, but due to the fact that Ford tries to run these trucks at near zero vacuum in order to boost mileage numbers. At the PCM level, the Roush blower is in by-pass until 80% throttle. A good SCT tuner can fix this. The throttle lag issue isn't a problem with the Roush tune though.

The Roush tune from Troyer and the larger pulley will put you well past the 385 range. I know, I'm doing that without the long tubes.

Thanks!
Lots of good information in the archives....
I spent far too long at the SEMA Show 2006 photos I must admit!
