V16 Engine How to set it up correctly?

People, I really need engine settings of more than 9,000 horsepower; I personally managed to achieve only such a record.

I want to build an incredibly powerful dragster for 1/4 and 2/4 miles before I hit the 6.1 second record, but that’s not enough for me.

I also have serious problems choosing a transmission, which gearbox is best for drag races, and how to adjust it correctly to get the most time out of the car?
