Performance Upgrades 3-Valve V10
Hello guys, new to the forum and also a new 2008 v10 owner. I've run turbo diesels pretty much my entire life and am coming off of a Duramax LBZ. I love the torque and power the diesels make but after running the numbers they just don't make as much sense as they used to.
So for I'm impressed with the 362 hp v10 but would love to gain some more performance and possibly mileage. Are there any performamce upgrades for the 3v v10? I can't even find an exhaust system for the 2008. Any help would be appreciated.

There is next to nothing available for the 3V V-10. Ford Racing Parts lists a set of shorty headers for the 3v v-10, but I don't of anybody that bought a set.
I ran SCT's tune that they claim is 31rwhp increase, but when actually measured on the dyno, it made nothing more. Seat of the pants feel felt better, because it held each gear longer and shifted quite a bit firmer, but the truth was 0 extra hp or tq, and 0 extra MPG. Then you also have your warranty to worry about if you do any programer.
Basically, what you got is what you got.

The issue here...is that the V10 3v has been done so well from the factory...that nothing aftermarket is going to help short of a Supercharger or turbo system. Heck...even the V10 2v didn't have much room for improvement.
IMHO...Remmy once your V10 3v gets up in mileage around the 10k...the fuel economy should improve...and the hp/torque will be released. The best for these engines is just to keep up with the basic maintenance.

Yeap, the boys above are telling it the way it is. The engine is making all it is going to make short of a turbo or charger. The good news is that somewhere between 5K and 10K (on average) that V-10 just flat wakes up and seems to come to life. You will know it when it happens. You will just one day start her up and go "WOW!)
As for improving mileage, that is all accomplished with the use of the right foot and the go pedal.
As for aftermarket exhaust, there are a few things folks have done to make the truck louder, however the exhaust tone of a V-10 is not the same as a V-8. Seems the V-10 results in a higher pitch once she gets the revs going. After all of my diesel years, I kind of like the near silent exhaust flow.
Enjoy the new truck.

Two valve project here, but the only turbo project I've seen carried to a successful completion! Would work with a 3 valve as well, but with different programming, which is the key on either project.

e the power is down much lower but I got a supercharged V10 you would have to do some sort of turbo setup I've seen both twins and single done and they work fine

Think about that for a minute…………
With those sweet Banks headers where would you plumb the turbos? After the headers is a lousy location as a lot of the heat and volume (from the gasses cooling) has already been lost.

I'm currently working on fresh billet cores in house for the 3v v10. 2v cams are working excellent so time to stretch the legs. But what most people are saying here is accurate. With the 3vs staying in factory rpm range there's really 2 worthwhile options staying N/A. Cams and compression ratio bump. And find a competent tuner I suppose if you're lucky. If someone made mid length or long tubes that would be sweet, but shorties do crap really compared to factory manifolds. If you never tow with the truck, you can look at electric fans and the meziere electric water pump as those both free up a nice chunk and some fuel eco for a pretty penny. If you throw a set of forged rods and pistons in it off the shelf from 5.4 2v engines and get a 5.4 Pro-charger kit. Walbro hellcat or 425lph pump in the tank (bolts into the factory bucket with slight trimming and some ford performance injectors (USCAR style i believe) you can tap 500whp nicely. Factory cranks are weak to superchargers as they have a very long unsupported snout that doesn't like load from a supercharger and will break. If you give it some good additional support 500-800whp is lightwork just not for the 5r110 behind it

Supercharger
where did you find the kit or is it a custom setup? Looking to do something with mine. Needing some info on what it can reliably handle.
