Love my Raptor - would like more power

[rumseyj]

I have a fully loaded Molten Orange 2010 Raptor with the 5.4L engine and I love everything about this truck. I just wish I had another 100 HP. I am interested in adding a Supercharger, but wonder if I would regret impact to engine life or any other negative side effects. Any experience with the 5.4 Supercharged that you can share?

well, SVT supercharged the Lightning with no ill effects so obviously the engine can handle a little boost. 380-400hp would be a reasonable number. and these transmissions are pretty bullet proof so they can handle it.

What decade are you living in? Thats not much of a supercharger if your only getting 60-80hp the Lightning was a old 2 valve motor with a old Roush blower

WELCOME! The 5.4 Triton has always responded well to boost, and there are a number of safe schargers out there. search the forum for superchargers. Pics are now needed of your Raptor

The 5.4L Triton engines are ok up to 22PSI on the standard "safe" side. They can go higher and take the pressure, but engine life is deminished. So if you get a Supercharger that averages around 10HP per 1PSI, you should make out alright. Most aftermarket "GOOD QUALITY" superchargers will allow you to go anywhere from 8PSI to 22PSI. So anywhere from 90HP increase to a possible 220HP+.

i'm well aware of the capabilities but not everyone likes to push the limits. the point is 90hp would add some pep to the truck's step with basically no loss of durability on the drive train and superchargers are much more reliable than they used to be.

I agree, this truck isn't like the Lightening where red light to red light racing is somewhat common and the truck is driven lightly most times. The Raptor has more to tolerate and placing the truck under more stress with more than 100HP will shorten the life span, especially under Off-Road conditions. The Triton can handle almost anything you throw on it, the question is, for how long? It's just like every other engine, over time it wears down. Bird is right, keeping it within the perameters of 90HP would be the best bet for everyday driving and Off-Road use. Anything more, and hopefully you don't drive it much so it lasts longer.

All good points. The Roush chargers that we installed on 07'-08' model F-150's with 5.4L 3v engines stood to gain about 120 HP. As far as I know, none have suffered any ill effects and I know of one that is used offroad very deliberately. Roush stopped producing chargers with the 09' MY (F-150) which I think really is a bummer. They were an extremely well engineered product and the fit and finish were VERY factory like.

Good points and I appreciate Aaron and FSM's opinions here. How would you blow the Raptor? Im not trying to say push the engine to its limits, not anywhere near it. But the Roush, while a proven unit in both power and reliablity, has been around for a while and I assume that scharger technology has advanced considerably since it was designed.

The Lightning 5.4 and the Raptor's 5.4 are WAY too different to make an assumption one will hold boost because the other did. The Lightning's bottom end was designed for boost; it is much stronger and built to support more power. The Raptor's 5.4 rotating assembly is basic (CHEAP) stuff that was never designed to hold much more power than what its factory rated output is. The Lightning has a forged crank, the Raptor's is a cast, the Lightning got heavy duty powdered forged rods, the Raptor's is very light duty powdered forged, the Lightning's pistons were forged, the Raptors are cast. The Lightning also had lower compression which prevents detonation when under psi, the Raptors compression isn't all that boost friendly for todays hit or miss fuel quality.

The Lightning used the Eaton M112 (1.85L) blower unit. The current Roush kit also uses a M112 Eaton blower. Its the same damn blower unit from Eaton. Roush doesn't build any super charger units. It's FAR from efficient in comparison to todays standards. A Whipple, Kenne Bell or any twin screw design blower will be a much better choice. The 3v head does flow better than the old 2v but it doesn't matter. The stock Raptor 5.4 bottom end will never hold the power to benefit from the extra intake valve when boosted.

The 5.4L Triton engines are ok up to 22PSI on the standard "safe" side. They can go higher and take the pressure, but engine life is deminished. So if you get a Supercharger that averages around 10HP per 1PSI, you should make out alright. Most aftermarket "GOOD QUALITY" superchargers will allow you to go anywhere from 8PSI to 22PSI. So anywhere from 90HP increase to a possible 220HP+.

Maybe the GT500 5.4 is safe to 22psi but the truck 5.4 wouldn't last one dyno pull on 22psi. 10 psi is tops for the Raptor 5.4 motor and even then its a grenade with the pin already pulled. If you want the Raptor's 5.4 to last and be reliable run about 6psi.

Maybe trading for a 6.2 would be a better option. 100hp, and warrantied.
