Alert! Info on V6 Driveshafts

[afixer]

Ok so i am tired as heck but im home i will make this short!. as most of you know i am the test mule for the x-charger. and yesterday while on the dyno at around 118 MPH my drive shaft exploded! do i have your attention i hope so. this is what we found. when this happened i was 100 miles away and could not do anything but find Dave from explorer express a new shaft and wait. all day and all night i speculated on why. after long talks with my 2 ford buddy and rygen, screamin and kurtv6 i kinda came to the conclusion that the v6 drive shaft was a piece of crap ( no duh ) any way my ford bud did notice that the new one had a new part number. Hum, so i showed up today and on the floor was the shaft broken in two and both u joints apart. as it turns out the 05 v6 drive shaft just presses in the u joint caps. at high rpm 110 plus the caps start to come out. (i will post pics soon) The u joints and the mounts are fine they did not break at the high rpm the caps shifted and the u joint simply cam out. i tell you all this because i know a lot of you are exceeding the recommended speed, we use to think that it was only the tires but its not. the up side to the story is i am alive no one was hurt except my car and they have fixed the drive shaft, oh yea did i mention the new drive shaft now comes with larger caps and retainer rings! i will post pics of them too. i have no recourse with ford i am not going after them i am owning up to the fact that the car was going faster than it should have. i say this because you are all my family and i don't want any of you getting hurt. check you drive shafts if you have the old style hopefully the will do a recall i cant its too late but please if your racing / modding to exceed the specs you should check into this. all others that just got the car for its pure beauty like i originally did you should be OK ! this only happened because the car was going too dam fast 110 to 120 thank you i hope this helps you. i will be posting a complete update later but i just got home and felt this had to be said again non performance cars are OK ( ford don't sue me!) but for all you gear heads and you know who you are! this is important.

Holy crap! A buddy of mine told me I should be able to get a custom driveshaft made for around $200. I'm going to call and see.

I think he meant MPH.

so is this something we have to be aware of regardless of a f/i application?
