Alright, I'll say it.

16.2/15.9 is pathetic for a '95 GS-R in lower elevations.

I ran my RX-7 in stock condition last October with a clogged exhaust system and questionable 6-ports. With wussy launches, I got a 16.2 1/4et, 2.3x 60'. This is in a similar weight car with a slight RWD advantage, but I'm figuring I had about a whopping 110 wheel horsepower at best (I've dyno'd it with mods since, so that would be a fair estimate.)
