 Cost Comparison
If you were to take a Kawasaki ZX-11, or a
Suzuki GSX-R1100, and do a cost comparison between turbocharging and a built carbureted
build up, you will be very surprised!
Our
target, for a strong street bike or a decent strip runner, is 180 rear wheel horsepower...
if you do the math... you will save $1400 (or more) by going the
turbo route... and you will have a much more enjoyable bike, and the "gee whiz"
when people see a turbo street bike pull into the lot will make it even better!
Our target comparison does not include things such as
aftermarket connecting rods, ignition components and fancy coatings... which you should do
to make a carburetor engine live longer! |

As you can see, the carbureted motor takes a considerable amount of time to perform machine work disassembly and reassembly. The end result can be quite tricky to obtain only after much fine tuning. The turbo engine on the other hand requires very little in the way of labor and expensive engine parts. The turbo kit can be installed in a day, and offer years of reliable service. The graphs here tell the final tale. At this level of power, racing fuel is used in both, but only the turbo bike can go back to pump gas for street riding, simply turn the boost down to 8 - 10 lbs. and go. Incidentally, by turning the screw in on the waste gate a few rounds instead of out, we can push this same engine to close to 300 hp! |
