wrx vs wrx

I ran into a fellow clubwrx member today and decided to have a little fun.

His mods: vf30 and turbo back exhaust.

1st run: we went from 35mph and at 110mph I had maybe 2-3 cars.

He however was in 3rd and I was in 2nd.

2nd run: this time it was closer. From around the same mph we
shut down at 120mph and I had maybe 2 cars.

He said he just ran it at the track and ran 13.0 at 105mph

I was amazed because of his mods. His car ran strong. Good race. I hate racing my fellow cars though. What do you think 2 cars are worth in the 1/4 ...Im trying to guestimate what I would run mph wise.... Good run man.

General rule of thumb is that at our trap speeds and car size, 1 car length is approximately 1/10th. That's always worked for me anyway, but I've never done the actual math to verify it. I just trusted the more knowledgeable people who passed it along to me. So lets see what happens:

WRX length = 178.5" or 14.85 feet.
A car travelling at 100 mph is covering 1.666 miles per minute (100 divided by 60)
which is .0277 miles per second (1.666 divided by 60)
which is 146.6625 feet per second (.0277 times 5280)
which is 14.66 feet per 10th of a second.

So, that settles it for me now!

I also go by 10 hp being worth 1 mph in trapspeeds, but that's only from experience and seeing other cars. Not sure if there's a good formula for that, and it's too late for me to try.

are you sure ? so that means I would theoretically trap 2mph higher.

Hey that was me! 13secwrx is being modest. Those two cars he had on me would have been more if we kept going. I too don't like racing fellow wrx's. It was a friendly encounter. In fact now i know 13secwrx lives next door, there might be some more stories to tell

Definately man. When you race your fellow wrx your working w/the same gearing, ratio, etc...sucks....Sti's however...nah j/k
