I don't mean to burst your bubble but ....

At 160mph speedo indicated you are actully about 144mph. Having made many timed runs on factory sized tires - I can attest the factory speedo is 10% optimistic (fast).

The 160mph speedometer is long buried before an actual 150mph is reached.
I can also tell you my car with significantly more power than 238WHP, shaved mirrors, seems sealed & taped nose, lowered several inches from stock, with a tail wind could only muster an actual 156.9 in a 2.25 mile run at 4500' elevation.
