Too Much Power?
Does he want to squeeze any more power from his shark? Well, yes and no.
"Because of the sled-pulling class rules prohibiting nitrous, the Great White has never seen the huge advantage of nitrous. Certainly with the quantity of diesel flowing from the massive fuel system, there is easily another 200 horsepower in the engine. We may never know due to the fact that the Great White continues to clean house on the pulling tracks."
For track duty it's not all about just the motor, though. A truck has to work both smarter and harder to be competitive, and that means some extensive driveline mods. Sean painfully recalls breaking the front axle spider gears four times, the axle shafts twice, and the aftermarket Super Winch hubs as well. Sean also beefed up the transmission by raiding the parts bins at his employer's factory. He threw in an ATS Billet 4R100 transmission, deep pan, billet shafts, and drums, along with the Co-Pilot electronic controller and a Five Star Viskus Drive torque converter.
Giving a nod to his employer, Sean notes that "the full ATS transmission package has been a real success in the reliability of the truck and is a huge advantage in the pulling track. The transmission is set up to allow for wide-open upshifts and downshifts during the extreme abuse of pulling the sled. At the end of the track the transmission is manually downshifted to transmit extra torque to the four wheels in hopes of getting every extra few feet."
