ok I have a question kind of dumb

[ryan_g35]

My buddies friend thinks that his buddies 04 g35 6mt will complete walk my 06 5at. I disagree becuase i have raced a 04 350z 6mt and beat him and the guy with the 350z was very good a launching. I have driven the 04 5at and it felt ridculously slower than my car .. but that was what it felt like to me.. Oh the kid is learning to drive a stick on the g and he believes that his has 310 to the wheels with a short ram and thats all. lol I dont really care he is just dumb lol.

Yes, dumb.

Now what is your question?

Where were you guys racing?

are you talking about me and the z? my buddy has a farm where has a long road that we used.. no we didnt on the street trust me im going on two years i know how they are about street racing here.. oh and the ex35 dude get out of here I don't need your opinion.

[G_whizz]

Yes, dumb.

Now what is your question?

Take it to the track and find out.

FTR...you'll win.

Does that answer your question?

An engine that outputs 280 HP at the crank, with a 15% parasitic loss due to inefficiencies, will produce 238 HP at the wheels. This is about where the output is for Gs at the wheels. To produce 310 HP at the wheels, the engine would have to be 365 HP at the crank.

Also, a short-ram intake will not cause a 30 HP increase at the crank, so 310 is not possible by any means. It's good for maybe 6 at the most. If he were right, his intake would have to improve performance to the tune of 85 HP at the crank. The only improvements of that kind one can see with a simple intake is on a diesel engine.

Your buddy's friend is a complete frickin' idiot, not just kind of dumb. Sounds like he needs a Honda with VTEC, yo.

Would the 15% parasitic loads really increase to hold true to these numbers, just curious? Its just seems that at least some of the parasitic loads would be of a more fixed nature.

Sorry smockers but I didn't clearify what I was asking.. Who would win between a 06 5at vs 04 6mt ? I know alittle bit about what you posted..but the reason I shared his belief about the intake was to show you how retarded this kid is .. I'm positive that I would espically because he is inexperinced in driving a stick.. Idk I try to stay out of the street racing espically because the g is nowhere near a drag car but is fun daily driver

What do you mean exactly? If you have the same powertrain and drivetrain, it would be of a fixed nature at the given 15% since you haven't changed anything. 15% of 280 is 42. 280-42=238. 15% of 365 is 54.75. 365-54.75=310.25.

The same powertrain is going to be just as inefficient, same goes for the drivetrain. To reduce the inefficiencies, you have to get better lubricants. That's where all of the synthetics like RP come in and how they "free up" HP.

What I am referring to is some things take the same amount of horsepower to drive. For example your alternator will not likely change the amount of power it steals. Your transmission has a certain amount of power it steals just to turn it. Your engine has a certain amount of loading for turning the camshafts, etc. The waterpump will still take the same amount of load to turn at a given water density. I believe most of these will not change all other factors remaining the same such as temperature, rpm, etc. So while they may steal lets say 30 hp on a 260 hp engine then they may still steal 30 hp on a 350 hp engine. Simply increasing the horsepower on an engine doesn't mean that the parasitic loads will increase proportionately. Some will stay the same, some will increase, but chances are they will not follow the same exact percentages across the horsepower range.

Good point.
