For current bragging rights, you can't beat it...this car is obviously a monster!
However when you take a look at the power and torque curve you can see that a stock car makes more hp and torque up to about 4k rpms (well into the power/tq band given the 6500-7000rpm limit). It looks like the turbos don't fully kick in until almost 5000 rpms which is relatively high for a 6500 rpm limit. Since this car makes roughly 2x that of a stock car you can see how quickly the power and torque build. This is a recipe for wheelspin and an undriveable car on the street on street tires. Put on some drag slicks and take it to the strip and this car will be unbelievable in the 1/4 mile. With street tires on the street, my guess is that a totally stock car will beat it to 60mph and 100mph.
Keep up the good work. It will be interesting to see how the clutch, tranny, drivetrain hold up to this abuse. The stock tranny is pricey.
