Re: Raced a 500+hp cobra this weekend.
Id assume around 10-15% parasitic drivetrain loss in a fwd... Maybe a BIT more in a rwd... |
Re: Raced a 500+hp cobra this weekend.
Ummm a BIT? On rwd you have a rear end and on the driveshaft you have u-joints which eat up energy. I'd put a good fwd at 10-15%, a good rwd 15-25%.

Re: Raced a 500+hp cobra this weekend.
percentages don' t apply.
it takes a certain amount of torque to spin it all and no more. 20% of 300hp is 60hp 20% of 8000hp is 1600hp why would it take more power to turn just because the motor makes more power? |

You know what im saying???? Granted the loss isnt linear, but the more power you make, the more is lost, its not a simple as saying that you lose athe same at 1000 whp as you do at 500 thats retarded..... I dont know, I do huff alot of race gas.... I could be a bit twisted... LOL |

Re: Raced a 500+hp cobra this weekend.
How about some dyno numbers and time slips? Maybe the guy in the Mustang was a super shitty driver. Then again racing from a roll is gay as hell anyways.

Re: Raced a 500+hp cobra this weekend.
met a guy last night, he was holding his steering wheel in his hand, someone else asked him whats up, he says his civic is mad tyight and it'll get stolen.
hes getting removable pedals next. then he says hes got a 350whp NA h22. i asked him how he got 350whp out of it, he said type r pistons and vtec. i laughed and asked if he wanted to race and he says whatta got a ls1 or something LOL... i laughed and said yes and he wouldn't race :( even if he just had a h22 in his civic it would've kept up for a bit :3 |
