Yesterday i got the chance to drive my brothers RB against his v-spec.Both engines on hyper 7 with almost the same setup and same tires.
Three words: NOT EVEN CLOSE!!
The vspec revs like crazy,i hear it and it's like being in a WRC car.
We tried drag racing on the straight of the track.I left first and by the end of the straight he got me.
OK it does have the same high speed as the v-spec, but doesn't get there as fast as the v-spec does.
We were running it with the JP-1 exhaust which is said to be he best for it,but i'll try it with the T2050 and see how it goes.
