Hi, just a quick question, has anyone done a good comparison between a RA close ratio box, and a WRX box as regards to 1/4 mile times, running equal power, say 320-330 bhp?
At what power does the RA's box become a hindrance with the extra gear changes?

Thanks,Mit

Had one in mine for a bit, couldnt wait to sell it, it was a hinderence from the word go...................

std wrx ratios seem the best compromise for me

Took my STI RA to Rotorstock lastyear and went up against a mate's WRX. He was running about 315bhp to my then 285bhp. There was nothing in it up until i changed into 5th, he got his nose in front.

I finshed with a 13.3 and him a 13.1, think terminal speed was about 106mph. I tried a 4th gear run after that but it wasnt a good move, the RA needs to use all 5 gears to cross the line!

The longer gearing would be better.

My RA is now my drag toy and the only time it really gets used is on the strip, i found changing to 5th a pain and have now gone to PPG for the longer gears..... 4th goes all the way to 127mph

Yep, 4th to 5th is the longest shift ihmo.

PPG gearing is much better
