Anyone heard the 2009 Yamaha R1?....it really sounds like a M1.....No doubt it's because the new uneven firing cylinders, but still......................

the skyline wins for sure

My boyfriends 74 chevy nova!!!! Well, he knows how to fix up hotrods he made his car have about 550 hp, pretty good I think

550hp is quite easy to get out of a 6litre + engine.

DONT UNDERESTIMATE MY BOYFRIEND!!!!!! and he has a V8 engine, small bloc. and he's on a limited budget so what he does with 2,500$ is pretty good.

Ew, USDM DC2 front end, but his crossover is insane.

Did you have the face of VTEC?

And there's nothing wrong with USDM DC fronts.

Haha, no I didn't but it look's like it added some mad power yo'

Yea, there's nothing wrong with it but its a personal preference and I just don't like them. And yea I know VTEC is supposed to be a smooth crossover on the power band, but just adding to thread.

best sounding imo,
rb26dett skyline gtr motor
ka24de with a turbo, sounds almost as deadly as an rb motor
4age withe itbs, or 20v 4age, and 4age turbo'd
b, h, k, and c series v-tec motors, sometimes d series that are itb'd
of course my lexus es250's 2vz-fe quad cam 6 cylinder always gets me with just an intake haha.

audi rs6
twin turbo V8 woot

High Rev, ITB or Carburated inline fours such as Honda B and Toyota 4AG... and the RB26.... OH GOD, YES!!!!.... get chills just listening.

my friend's built k20 running open headers... you hear it over two miles down the road at WOT

He didn't underestimate anyone. he simply said 550hp is easy to get in a V8, in which, you've also confirmed by your statement by saying your bf did it with $2500.
