H&S is trying to break a 6.7l scorpion turbo diesel and see how much power it can take. Stock tranny and bottom end of the motor. They baselined it with fuel only at 600hp, added a 60 shot of giggle gas and got 700, put a bigger solenoid on and a bigger shot and got 750hp. It is still kicking. time for more nitrous and see if they can get 800hp.
