new 1/4 mile time!!!
 
Went 2 the drag strip last night I ran a 15.7 with my best R/T of .009.My old best was a 16 flat but since then I installed edelbrock headers so I got a pretty good gain.I think its a good time its only a 4.8,go back next week see if I can get a better launch.

I don't know what the stock 1/4 time is with a 4.8 rcsb but I know I ran a 10.61 in mine in the 1/8 stock.... well okay I had a K&N air filter but no redneck ram air so you get the point.

I'll try 2 get some video up next week along with some timeslips.These rims and tires are weighing me down though I think I might get low 15's on stock wheels and if I adjust a couple things on my predator.What's the best way 2 run the dragstrip in D or manually shift up from 1st?

I like to use the tow/haul button try driving around with it on it is pretty cool. It will make you Flowmasters sound even better because it strings out the gears a little longer and then bamm it hits the next gear a little harder.
