I have a GTech Pro Competition that I would like to try, but it's asking for my vehicule weight...

Here's the description of my car if that can help:

1989 Chevrolet Camaro IROC-Z, Hard-Top, 350 TPI, automatic, 2.73 POSI disc, electrical windows/mirros/doors/hatch... It DOESN'T have AC, cruise control and power seats.

Hope some of you will be able to help me out.

See ya!

 

i have an 88 iroc and my wieght is 4215lb. with the a/c dont know how much that a/c weighs but, thats the weight, if you look on the driver side door it will say GVWR or GVW and that will tell you the weight.

 

That's not the actual weight. My '87 IROC weighed around 3450 lbs w/out me in it a few years ago. That's with aluminum heads and water pump, no air pump, functional A/C, and welded-in SFC's.

 

So by enterinf approximately 3600lb, I should be pretty close eh? Anyway I only wan't to get a pretty accurate 1/4, 1/8 and 60ft. So the weight shouldn't matter right? The HP and torque number are not that important too me. Anyway, I could translater my 1/4 trap speed with a formula to get my approx HP numbers right?

 

Depending on how much you weigh, 3600 should be somewhere in the ballpark. The trap speed is the best indicator of how much power you're making, but the G-Tech uses weight as part of it's calculations, so entering incorrect data does throw everything off by some percentage.

FWIW, I weighed my GTA at a rock quarry once (they sold rock to the public by weight) & with my 200+ lb carcass in the car, it came to 3750...

 

My 91 Rs with the LO3 weighed 3258 with a relatively large duy driving it at the emissions test place and my friends 85 IROC with the L69 weighed 3101 at the emissions test place as well. I havent weighed my IROC yet though. i think the 4000's and 3700's are a bit high but hey thats just me.

 

My fully optioned Iroc with A/C weighed in at 3670. Guys on the board that have removed ac have noted 70 lbs difference in weight. So with a 200 lb driver and no a/c, you car should be around 3600, or 3400 without driver.
