Re:how much power do you loose?.....
 

too many variants for there to be an exact #, clutches, transmissions, axles, ---- like that.

Re:how much power do you loose?.....
 

wheel size, gear size, flywheel weight, all of the above

Re:how much power do you loose?.....
 

thats the dumbest thing ever dimitry... your trying to say you have more hp then you do. you made 188 hp to the wheels, i want to here no more of this ----.!

Re:how much power do you loose?.....
 

you can easily say u make 200hp :P

Re:how much power do you loose?.....
 

no it's not that... i am just trying to figure out how much horse power i have at the crank comparing to my WRX... ---- I ain't trying to tell no one that i got more HP then i actualy do... THAT would be dumb 8)

Re:how much power do you loose?.....
 

who cares? whats the diff in 300hp and 250hp?? nothing if they both run 13 flat, hp is horseshit

Re:how much power do you loose?.....

13-15% driveline loss for FWD Honda's (dyno coast down tested)

Whats the difference between a 330 whp CRX and a 550 whp CRX??????

About 1 second faster with less hp.

Re:how much power do you loose?.....
 

Don't you mean kph ya damn canuck? :P

Times on a standard track are better than just hp and top speed numbers IMO.

Re:how much power do you loose?.....
 

its ok hes young and stupid

Re:how much power do you loose?.....
 

---- you are dumb, MPH at the end of the quarter mile ::)

Re:how much power do you loose?.....
 

Drivetrain loss is NOT a percentage, never ever.
If your drivetrain loss is actually 20hp (and no, these coastdown tests are bullshit) and you are putting for example 200hp to the wheels. Put in a 50 shot of nitrous and you will pretty much make 250hp at the wheels. Hence drivetrain loss is purely a factor of speed and not torque.

Dyno dicks usually boost up their bullshit numbers by percentaging drivetrain loss. I can very much assure you that a 2000hp top alcohol dragster is not losing 200hp+ in the transmission. If that was the fact then the gearbox would pretty much boil all the oil in every run. I'm talking about a manual box here with no cooling at all.
