No it got it correct on my civic, I did not do my formula as I dont even know what it weighs

 

Only made one pass on track and burnt up my clucth but ran a 14.2 it said i should run high 12's. could be close if i had a better clutch slicks and better half shafts.

 

we are also forgetting driver skill as well

 

I got skills lol

I was yanking high 15's with a Y7 with bolt ons and the p.s./ac removed. I shocked the hell out of a couple guys in EM1 and EP SI's.

 

Hey it was my first time at a track, i'm working on it. Man you guys are harsh.

 

Naw man I was not refering to you. You have traction issues, what were your 60 foot times?

 

2.8 60' time. Car is hard to launch to little rpm bogs to much spins. I just need some pratice

 

well i think its assuming RWD with all the parts that were originally belted to the engine. your ac lackage is probably what threw it off because it takes a lot more power than people think to power ac.

 

I don't trust any of those things.

 

they are fairly reliable...horsepower is a function of of weight travelling at a given speed, in a given amount of time, or acceleration.

H=M x V

all of the horsepower calculators simply plug in the M and V, and it gives you the horsepower. mind you, this equation isnt the exact equation used, but it gives you an idea. All these ET calculators do is solve for V instead of H.

typically, the more accurate calculators use MPH rather than ET. the ones that give you an ET, or use the ET to figure out HP, are assuming a perfect pass.

I have never had my car on a dyno, but i know alot of guys who have, and when we compare trap speeds and weight, i have about 360whp, 425 crank hp, and at 3700lbs, its pretty accurate.
