I have this deserted road near my house and I thought i'd do a speed run to 90 to see what times i'm getting. My speedo is right on the money now that I put a 23 tooth TCI gear on the cable. I even checked it with my hand held GPS...isn't technology great! Anyhow, from a standing start it does zero to 90 in 9.79...seems pretty good...but i'm really not sure. This is with a 3.50 posi rear. I get a little tire spin up to 15-20 or so but for the most part the Falken 451 245 tires grip pretty well. 90 is almost redlined in 2nd. My shift points are 6500-6600. When I go to the drags, I plan to pop a 4.11 posi in and slicks so the times may be a bit better. I think my secondaries on the street avenger 770 are opening all the way now (I had a problem with the shaft bushings binding the last time I had a chassis dyno). I'm curious if anyone can extrapolate this time to 1/4 time and trap speed?
