Time Slip Analysis / Help?

[slick-metal]

6 Runs...
I am also a Convertible, so my base weight is heavier than a coupe. I have about @200 lbs of stereo/subs etc that is not really removable (molded/glassed in. I weigh about 160lbs. I removed the spare/jack and passenger seat..rear seats deleted due to music stuffs.

Automatic Tranny - 3.08 open diff. - Launches usually around 1500 rpm..
Was sunny, pretty warm and a bit humid...but most runs were consistant and didnt vary enough as it got warmer. Bitburg, Germany - old airbase flight line converted...(not street tire friendly) 18" Street tires. Also found later that day my right side front tire was LOW, like 22 lbs. :( Mods in Sig block

I know proper inflation of the front tires will help me roll through the 60'...I will be smarter next time. LCAs were installed as well.

Any help is appreciated! I am trying to devise a way to easly remove the stereo equip.

found my yellow top battery is 12 lbs heavier than the stock one...I will replace that next time as well.

You have intake and exhaust

Low 16s/hig 15s is abotu right for a "stock" 3.08 open rear 3.8

Your car is heavier beinga vert, you said yourself you have EVEN more weight with the stereo stuff, It was hot/humid? Also the 18" rims are killing you.

All that being said you're probably about right on where you should be.

dump the stereo run when it's cooler and put some stocker rims on there and you'll pick up quite a bit of time.

From there your next step is gears/lsd probably.

yeah, installed the LCAs to rid the nasty wheel hop I had...that improved my 60' foor about .2 at most...I'm going to try and launch a bit different next month.

I have 3.42s and a ZT LSD to install...Just need to find the time to get them installed, at a good price and break them in.

Hmm, my stock 16" rims have a bit of bald tires though. Worth a shot?
