2011 F-250 Super Duty Tops 182 mph.



182 mph thats 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-250s 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 comparisons 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-250s 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-250s drivetrain and transmission were stock.

I have a hard time calling that mostly stock.

That is drag strip stuff.

I would bet they changed the rear gears to 210;1 or 173;1 also for the top speed.

Using the stock axles and housing.



JMO...
 
I wouldn't call that stock either. Thats like $7000 in mods lol.



Thats like taking a Lightning's 1.8L Eaton and throwing on a 3.4L Whipple and calling it stock...



No.

I agree and disagree at the same time.



Replacing fuel pump and injectors are pretty common mods that are simple and effective. Replacing turbos is something more extreme, but still not that extreme. How was the compression raised? Was it new pistons or was it decking block and/or shaving the heads?



Still not major of an upgrade, in my opinion.



New crank, punching and stroking the block, custom grind on the camshaft, etc. is something I would consider serious.
