Post Quarter Mile Times Si/2.5RS

Hi Guys,

I've been keeping an eye on one of the message threads involving someone who wanted to race an Si- and whether or not he could win, I've been a bit curious myself, (from a performance standpoint) which car is quicker in a straight line- I pulled the following data off of gr8ride.com, which was in turn sourced out of Sport Compact Car's '8 great rides of the year' article- Anyone have any thoughts on it's accuracy?

Impreza 2.5RS
0 - 30 mph
2.4 sec.
0 - 60 mph
7.7 sec.
30 - 50 mph
3.1 sec.
50 - 70 mph
4.7 sec.
Quarter Mile
15.7 sec. @ 85.7 mph

Civic Si (SiR in Canada)


0 - 30 mph
3.3 sec.
0 - 60 mph
7.9 sec.
30 - 50 mph
2.8 sec.
50 - 70 mph
4.3 sec.
Quarter Mile
15.9 sec. @ 88.5 mph

I think that looks about right. I am upset because I can't find the timeslips I wanted...I went up against an Si twice that night. I was surprised that the RS was actually a little faster in the end as well, I think I had around one mph on him. Of course I have an intake/exhaust/pulley and I think his car was stock, but not sure.

Well there are no dyno results to back up what im saying, Subaru decided to not redyno the engine.

But the 2000+ have a higher compression, as well as a redesigned intake.
I would expect the 2000+ to dyno higher.

higher dyno means higher hp and/or torque. Yeah that would tend to put you a bit quicker.
I may get slung to a pole by some 1999 owners
