Ford F250 sets speed records at the Bonneville Salt Flats

[JCE]

Built Ford Fast?

2011 F-250 Super Duty Tops 182 mph.

182 mph — that’s how fast Hajek Motorsports and Ford Engineers got their 2011 Ford F-250 Super Duty to go. On its way to 182 mph, the 6.7-liter turbodiesel V-8-equipped F-250 set not one, not two, but three production truck land speed records at the Bonneville Salt Flats.

The three speed records that this lightly-modified F-250 broke were in the B Production Diesel Truck class, at the Bonneville Salt Flats. The truck broke the biodiesel record, using soy-based fuel by hitting 130.614 mph. The F-250’s second fastest record of the day was using regular diesel fuel, where it managed to hit 171.123 mph. The third and final record of the day was using B20 biodiesel, where the F-250 topped out at 182 mph. For comparison’s sake, the old record was set by a Duramax-equipped GMC Sierra HD, which only managed 166.850 mph.

The most remarkable thing about the F-250’s speed is that it the truck remains mostly stock. Ford says that its engineers and Oklahoma-based Hajek Motorsports only installed a high pressure fuel pump, new fuel injectors, new turbos, and modified the compression ratio. Aside from the performance modifications, the F-250 was also fitted with a roll cage, five-point harness, a drag chute, aerodynamic fairings for the front bumper, and the obligatory salt flat moon-dish wheels. The F-250’s drivetrain and transmission were stock.

Now that's sweet. I wonder what that felt like in a Superduty truck...going 100mph in one is insane much less 182mph.

It probably feels something like



AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The truck looks lowered by a good bit.
How do you modify the compression ratio in a turbo diesel without tearing the motor apart and putting in new pistons, among things?

Thinner head gasket, decked head. Can be done up to a point before you get piston slap.

Didnt know something that big could go that fast without the help of a rocket on the back...

You'd think some side skirts would help out a lot, unless that changes its classification.

182mph is impressive but it was not a production pickup. The motor had been modified. Check this video out. This one is straight off the production line and it wasnt sent on smooth salt but a normal road and best of all its a General Motors car.

Is there anything about this post that is relevant, or...

Right, when you start doing internals you shouldn't call it light modding or mostly stock. Maybe it's the tone in which they wrote it, "yeah we barely did anything to the truck".

Ford versus Chevy, that's the (ir)relevance.

No, more an Aussie trying to say how a car with a bed on the back doing those speeds is more impressive than a body-on-frame diesel pickup doing the same thing. which it isn't. In fact, it's probably less impressive.

Have to agree with this ^

Diesel seems more impressive.

Clarkson may have just shot himself.... (He did 176mph in a Corvette ZR1, stock)

That's crazy, I couldn't imagine going that fast in that big of a vehicle. Props to the builder(s) and the driver. I wonder if that was a 4X4 or 2WD F250?

@commodoreben, the Aussie get all the good stuff while the U.S. gets the crappy cars. Yeah we have the Camaro and Mustang but we don't have the Holden HSV W427 or Ford Falcon FPV Boss 335 GT.

Bells went off to me when they talked about the upgraded fuel system and turbos. That's all you need to make power with a diesel.

*throw massive turbos on anything*

"Yeah its basically stock."

 

[shmogt]

what record did it set?

Did you not read the first post?

Rrrrrriiiight, totally stock.

To be fair, only the engine stuff there is worth rolling your eyes over. I wouldn't begrudge anyone who wanted to fit a roll cage and other safety mods to their 170+ mph diesel truck...

 

[eSZee]

I'm assuming they wouldn't have been allowed to attempt the runs without a cage.

 

[Dennisch]

Nice, I would like to try that! 👍

 

[Eunos_Cosmo]

So they upgraded the fuel pump, turbos, and raised the compression ratio.

Keep in mind with just a tune, these engines are often capable of well over 1000 lbs*ft of torque. I bet this engine is something around 700bhp and 1500lbs*ft.
