Looks like I possibly popped my short block

**Seer** · 01-19-2013, 10:36 PM

So I was driving home last saturday night and decided to put my foot to the floor in my Shelby. Well, about top of third, smoke came from everywhere and oil all over the bottom of the undercarriage.

I pull off to the side of the road and the hose that connects to the fuel pressure sensor was not attached. So that is the likely culprit.

I'll be ordering the FRPP Iron Forged 5.4 short very soon. I am not sure if my current block is salvageable or not, and I won't know for a few weeks.

That sucks man. Mods? Mileage? I was wondering if these aluminum blocks would hold up to big power.

To be honest, I do not feel it was the mods, tune etc.

When I popped the hood, the fuel pressure sensor valve was not plugged in, and it was plugged in earlier. Looks like it blew off during WOT. The car was making 750+rwhp.

That sucks. Such a terrible feeling when you see smoke like that.

IMO they should've stuck to the iron blocks like the 03/04s. A piston upgrade and possible swap to I beam rods and guys are making over 1k rwhp reliably.

A $50k+ car should be able to handle a good amount of power (unless it was the sensor blowing off that created the detonation).

If your block IS salvageable you could throw the new iron forged 5.4 into the shelby and overhaul the OEM block with bore/pistons/etc for your '12 GT?

Haha i knock on wood before i get in my car everytime. 240 extra horses on a stock block doing 160 pulls is scary.

Man sorry to hear this . Fingers crossed it isn't catastrophic.

I planned on putting a built short block and a larger blower with a return style fuel system in this year anyway. just so happens, it happened sooner than later.

I couldn't imagine it not being the sensor that caused the issue.

The base fuel pressure on the shelby is 39psi until that sensor detects pressure in the lower manifold (boost) then ups the pressure to 59psi.

Well With that sensor's valve side not being hooked up when this happens, tells me it was running at 39psi fuel pressure when it needed to be at 59.

HAHA you guys are nuts... I don't have the balls to make pulls to blow up my 9 year old stock Terminator, let alone a brand new Shelby.

**street591** · 01-20-2013, 12:10 PM

Any chance warranty would cover something like this? I mean if the sensor blew off, that should be their fault on not so good engineering..

**u1arunit** · 01-20-2013, 12:13 PM

Sorry to hear this Jay. Have others had this happen?

Warranty coverage would be a good trick as car has lots of mods. ;)

Yeah, I am sure they would have no problem honoring a powertrain warranty on a car making 250 more horsepower than stock.

...cause I know his mod list off by heart.

Good luck with it J. Hope it's back on the road by spring.

not really, still ended the season a lot faster than you :D What does a tune have to do with a fuel pressure sensor valve coming disconnected under wot?

Karma for what? What is your reason for your insane jealousy?

And btw... everything is for sale for the right price, I do get bored easily of projects.
