hi i'm made 4 passes some weekends ago and my best run was 15,08; 2,148 in 60ft. full stock (dakota r/t 2000 regular cab).

now yesterday i returned to the track, i remove juste the air filter et lower my rear pressure tire a 20psi. that's all i did different from the first time and my worst time was 14,77 and better (very happy of it) 14,54..also the first run of the day:jester:

question 1
does just the fact i remove the air filter, lower pressure tire and gently smoke the tire will reduce time about half a second or i wasn't good enough the first time?

question 2
for a full stock regular cab...street tire, let te trans shift by itself (o/d of too)14,54 is good....average...or ???

thanks

take this stuff an make a ram air tube. the dia is just big enough to slip over the end of a K&N tube snugly (no filter on of course) but you form the tube to go from the end of the tube to the opening inbetween the rad and the rad support. then double wrap it in the aluminum tape for rigidity. it's a cheap ram air for track racing only. worked good for me.
