Also, don't forget that most cars are mass production items. Car
manufacturers will re-use existing parts as much as possible to save R&D
costs which is one of the reasons a Viper or a Corvette costs much less
than a comparable Ferrari. In the case of the Viper, Dodge simply took an
existing truck engine and re-tuned it for performance in a sports car.
Who's to say it couldn't make 1000bhp if they really tried ?! I believe a
few tuners did. As long as we look at V10s, what about the 'new' Audi V10
which makes around 400bhp. It's based on the Gallardo V10 btw. Audi
saved money by re-using an engine from their 'parts bin' and tuned it to
match the work required from it. Who's to say it couldn't also make
1000bhp ?! All this is NA. Fact is, you could turbo anything.
If any of you watch that british show called Top Gear, you might have
seen how the 400bhp Evo could hang with the Murcielago on their track.
Thing is, the Evo had the same crappy plastic interior as the base
models, horrible turbo lag and a clutch hard enough to make you walk in
circles for days. Reminds me of something i read in a magazine once.
At the end of the day, the driver of the Evo is still going home in a
Mitsubishi while the driver of the Murcielago is going home in a
Lamborghini. The fact that the Lambo is used as the benchmark should
tell you something
