I'll guess mid to upper 15's.

Just made a run last weekend. My best was 15.3 @ 89mph.
I weighed in at cca 3700 lbs.
Completely stock 305TPI with a T-5 that I dropped in myself. And VERY LONG gears, 2.73.
Fried the clutch during the last two launches.
But I still managed to spank a modified CRX and also a modified 305TBI (headers, chip, exhaust).
Hope this helps.
