2000 F350 - Too Much Torque!!!

Truck is the one in my sig.

I just put the injectors in about a week ago. The truck now makes so much torque the motor is twisting and the serpentine belt is now hitting the upper radiator hose under a hard launch. I have had the hose blow off once and I have been through 3 belts since the injector install. When the belt his the hose it pushes it back and the pulleys and shaves the back 2 ribs off the belt. Motor mounts are STOCK but only have about 25k miles on them.

Has anyone ran into this problem before. Do I need some better/heavier motor mounts? Do I need to chain it? I know there are a lot of guys running the same combo as me (38r and stage 3s) so if any of you guys could chime in that would be awesome.

Thanks!

Never had that problem. Ive launched hard at the track a couple times and haven't experienced any of that.

I think there is a company that makes a re route for the top radiator hose that goes over the belt instead of through it. That might give you enough clearance. And it allows you to change your belt without having to remove the top radiator hose.

All of that being said, I think you better start looking into the root problem. Something ain't right.

Just too much stinkin' Ferd powah...

Alright my guess is the motor mounts were junk out of the box then (i think they came from autozone or something like that). Ill through some new stockers in and see what that does. Do you happen to know any more information on where to get that upper rad hose. I would love to have that; I'm so sick of taking it off and spilling coolant every time I have to change the belt.

Just go anywhere (not autozone)and tell them you need a upper hose for a truck with the ambulance package/dual alts.
The NAPA belt will be a Gates so you can get the same belt at Oreillys or advance also..

What kind of torque will a 7.3 with that set up make to the wheels? I never pay enough attention to pstroke power numbers(at least 7.3s and 6.0s)

Advance auto motor mounts If you haven't had the truck on a dyno or if you don't have a time slip there's no point in making up power numbers.

I didnt get advance auto motor mounts. And the numbers I posted were from people I have talked to who have the same combo and have dynoed there truck. I was trying to answer the question to the best of my knowledge. I didnt make up any numbers that is why I have stated that the numbers were from other people I have talked to. I never gave a number for my truck because I havent ran it or dynoed it yet.

He didn't really claim any numbers though. Just answered my question. That's all I was looking for, a general idea.

Pretty close to my setup. Im just running a little faster nozzle. Torque numbers should be around 900 to 1000lbs. Mine made just over 5o0hp. I have no problems with the motor moving. Still on my stock motor mounts. Ive never seen any that needed changing.
