I have a story that is slightly related to this thread.
before I begine let me relay the grain of salt everyone should take with this story: all of the following took place inside Forza Horizon 2, an automotive videogame.
me and a friend had the exact same car (a camaro) and we wanted to race them, so we each took our cars to the autoshop and agreed to not push our cars past a specific performance level.
I swapped out the cam for a better one, lightened the flywheel, opened up the intake and exhaust, and put better valve springs in it.
brought the redline up by about fiteen hundred RPM from stock with an additional 50-60 HP.
then came the race.
all I saw was the backside of a camaro with a bone stock engine, but a five speed where I has a four.
speed, sometimes, is not found in your powerplant.
