What a stock SST will run depends on elevation (& weather) Being at or below sea level you have us all at a bit of a disadvantage

Stock SST in Denver CO may run a 17.0 et (5800'AboveSeaLevel)
Tulsa AZ, 16.4 (3000'ASL)
Cayuga ON (where I race) 15.9 (700'ASL)
Englishtown NJ, 15.7 (87'ASL)
Netherlands maybe around 15.6 (zero to 5'BSL)

Regardless 15.0 is a fairly decent et. Your exhaust isnt stock, maybe one or two other things not stock also. Do you know what gears you have? (underside of hood) Back in Oct96 my Indy ran 10.185 1/8m, 15.9/85 1/4m. I didnt see 96mph trap speeds till I ran 14.0-14.1 ets.

Big rims look great but as you have noticed they do slow you down. Reason is rotating weight on the driveline costs et and the big ones can weigh a fair bit. At the track I use 15" Weld Draglite with MT Sportsman & ET Streets(skinnies/slicks), 136lbs total. Stock Indy rims & GY Eagle GTIIs are 264lbs (SST had same rims/rubber) AR 22s w/Yoko 285/35/22 are 330lbs. Guys with 33s & 35s could be looking at as much as 400-500lbs!
Id guess your SST to weigh about 4530lbs seeing you have a bumper. F/G tonneau & rollpan my Indy was 4455lbs. Btw thats a very nice clean looking truck you have

Any of you that have 1/8m et/mph you can also use this calc to figure out your 0-60 http://www.wallaceracing.com/0-60_equation.php

 

Thanx for the lots of info you gave me..
Next month there is another day here in the neigbourhood that i can race again, then i try it again.

Can you tell me were i have to look under the hood? is this in front above the radiator? i see a lot off info there.

Youre right about the rims, this looks good but drive not very fine, i drive now on my stock rims and this is much better.

 

Is this a temporay setup with timing they do where you live?
Think Drachten has a full time dragstrip or is that temporary too? Pop the hood & look up at underside, just behind the grill. Later model years could be in glove box or driver side open the door and look around the latch loop.

Just searching drag racing in the Netherlands
