I'm going to assume 450HP stock (crank)
So around 400WHP + 50HP tune and +50HP E85 so 500WHP at a MINIMUM
I would also guess 500TQ + 75 tune and + 75 E85 so 650WTQ at a MINIMUM
The TQ is key, the truck already moves smartly in my '15 stock, the new Raptor stock will already be amazing stock as well with 100+ more TQ already.
400 RWHP stock seems generous in a Raptor. Driveline losses in these trucks are closer to 20% than 10% in my experience. But even with your numbers they won't be more powerful than supercharged Gen 1s. At 500 RWHP they would probably be faster due to the weight difference but drag racing is really not what Raptors are made for.
I'd be in a Platinum if I wanted a street truck.
