1/8 to 1/4 conversion

[chadly]

Well I went to the track for the first time and had a blast. I had no expectations, but hopped to run in the 8’s (1/8th). I just wanted to establish a base point to build on. I ran against a variety of cars and won all six races. I ran consistently on cheap street radials:
60ft = 1.9’s
ET=8.2
ET=85mph
I was very happy to see this as I’m running a 100k motor that is basically stock w/minor bolt on’s. What would you guess to be my ¼ times to be?

Thanks Chad
P.S. the best was a guy I ran my second race. He had a new dodge charger r/t. I thought he said 6.1 liter. He said he had it on the dyno and it gave 426hp with a top speed of 169mph. He snuck up on me while I was making adjustments to my car. He asked what he had lost to and when he saw six spark plug wire’s and I told him it had 245 hp and stock block heads and cam then the F bombs were flying.

multiplying the 1/8 mile by 1.557 usually gets you pretty close.
