When Eddie Hill was competing in NHRA Top Fuel racing back in the late 80's and early 90's, I saw an interview with him. The interviewer asked him how much the motor was worth in his Top Fuel dragster. He said from the top of the supercharger to the bottom of the oil pan he had right around $75,000.00 in it. I'm guessing that with inflation factored in today that amount would be closer to $100,000.00. I knew a lot of women that came cheaper than that! Bill T.
To give you a idea on the kind of money we are talking about here. The blowers with out any pulls or a snout are $9200 each, from PSI.
Each pully is about $500 each, you need 2, the snouts are about $1200 for just the housings, the shafts are another $500. So for just the blowers you are looking at about 14k for blower and the other "stuff" needed. Some where in the ball park of 25k for just the stuff hung off the motor. Not including exhast systems, which are another 5k as they are for a boat. They are 100k each easy. I would not be shocked if its close to 150k each.
Something else to think about, these motors are basicly rebuilt after every race. Throw away everthing but the block and heads. That is assuming you didn't break anything. Topfuel cars you have to throw every thing away but the block/heads after every run.
