On the fuel side of things, a Scheid P-pump with 13mm plungers providesplenty of diesel to the engine. While keating did the machine work, engine assembly was actually handled by Darren himself. Although the truck has never been on a dyno, estimates based on quarter-mile speeds and e.t.'s. indicate more than 1,000 horsepower at the flywheel.
 What is it? nope it's not...  What is it? nope it's not a "canoodler valve," but that's a good guess. It is actually a drive pressure relief valve that vents excess drive pressure to the atmosphere to keep the turbos from overspeeding. |  Why are many drag trucks extended...  Why are many drag trucks extended cabs? Here, Darren gives you the answer: the further a driver can be set back, the better the weight distribution of the vehicle. In a diesel race vehicle, this is especially important, as the diesel engine weighs about 400 pounds more than the gasser it replaces. |  A Mark Williams rearend and...  A Mark Williams rearend and koni shocks are standard drag racing parts and help keep the truck planted despite 1,500-plus lb-ft of diesel torque. |
The other big news on this truck is the transmission. While many drag trucks are sticking with proven drag race pieces like Lencos or Liberties, Darren decided that the extra gears and advantage of a lockup converter tip the scales toward a diesel-specific transmission-in this case a 47RH. The Dodge transmission is far from stock, though, as a custom manual valve body with a transbrake was made just for this application by Suncoast transmissions. The rest of the transmission uses Suncoast parts, as well, and was assembled by Darren himself.
One of the more interesting things about Darren's truck is that it is nowhere near its full potential. Its first full pass at the DHRA finals resulted in a 9.17 at 147 mph in the quarter-mile. but wait, there's more! The pass was on a burnt piston caused by an insufficient fuel supply to the injection pump. On earlier 1/8-mile test passes, the S-10 scorched the strip to the tune of 5.50s, which translates to a mid 8-second pass in the quarter-mile. As diesel drag racing advances, look for this truck to keep pace. Plans for an even larger motor are in the works, as well as updates to the fuel system. This truck will be one to watch in 2008.
 Much to our surprise, Darren...  Much to our surprise, Darren told us that the tall 5.9 Cummins fit under the cowl hood of the truck it was delivered with. The sloping front end helps the aerodynamics at the high speeds this truck will see down the quarter. |  To make sure the truck has...  To make sure the truck has plenty of traction, a set of 33x17x15-inch Goodyear Eagle drag slicks are used. With 60-ft times of 1.28 seconds, we can't argue. |  |

The wheelie bars and the chute are both functional and needed.
