Except when you take into account turbo lag and a peaky power band.
There are two issue that come into play with the viper that doesn't happen with a Supra.
1.) Detonation. Due to the larger area of our positions, you can't run as much boost compared to a smaller engine. Big Block V8 guys got it worse. ci vs ci assuming all other 10 million variables are = a v-10 can handle more boost than a v8 of the same ci.
2.)rpm. The viper motor can not rev to 8500rpm-9000rpm. 6500rpm seems the best we can do without a roller cam ect.
So in-order to make up for these two huge draw backs, we need more cubes. More cubes we can get.
(How the hell do you get 575ci out of a viper motor. :shocked: 9.3L if my est is right.)
Maybe I'm not like much of the viper crowd, I personally don't want to make my power on anything but pump gas and boost.
Last I check supras make about 600rwhp-650rwhp on 93 pump gas w/o the water&meth inj. But then the turbo lag is a bitch isn't it. Why don't we see more stroker supras. Just to make a point clear before an all out war starts. I'm not slamming the supra.
