Trying to get 1/4 time?

[wandererdenali]

In my area there is not a drag place where they time. I have to drive 1.5 hours away just to get to a good drag place(thats legal). I tried timing it my self and got a 14.5. Dont know if i belive that i was running against a 2002 trans am with ram air auto and only got me by a car was next to his bumper. Everyone was impressed by the truck first laughing at me next giving me propts. the truck is a Sierra Denali 2002 6.0 whipple superchargered do not
know the exact psi have not missed with that no cats true dual exaust royal purple oil dont know if that helps or not. was wondering if any one has a similiar truck with some of the same parts that can give me an estimate or if someone can guess. also have raced other cars like a camaro with lt1 took him a 6.0 gto with headers and air intake throttle body spacer took me by 2 cars a supercharged C5 (my bro) with street tires of the line i was gone then took me really bad my first race after i finished supercharging it.

1.5 hours isn't bad. just make the drive!

I gone a few times they just dont time.

No timers?

You're probably close from what I've seen from other almost stock supercharged Denalis but the only way to make the claim is do it on a timed track.

PSI? What size pulley you running? the stock one that is supplied with the kit?

if you have a iphone - download the g-tech (or what ever they call it)program and has shown to be pretty close to true 1/4 mile times.
