[427]

I raced my car stock in the Big Bend open road race in the 140mph average class and did well with the stock engine averaging 143.9 all out on the 59 mile run down in the morning. On the morning run it hit 154mph top, but mostly would run 148-150 on most of the straights. I'm running the 150mph average class in October, so I need 160mph top speed ability. I think 15hp would likely get me 160, but 20hp would be better! I've looked at the Mishimoto intercooler and induction tube between the air box and turbo. Also thought about deleting the cat for the run. Currently the engine is stock (2020 6 speed stick) with only a thermostat change. I will be adding a trans cooler as it ran over 270F on both runs in April. Would the intercooler and intake tube be worth 20hp?
