Well during the Toledo meet I made the trip out to Milan with my 90 Turbo Grand Prix to make a few runs. As far as the car goes it hasn't been on the road since the year 2000 until this past weekend. Nothing mechanically has been changed on the car since I bought it. So spark plugs, wires, air filter, are old. I am guessing the last service of the car was around the mid late 90's. Everything is stock from the air box to the exhaust tips. The only issues with the car is that I have an exhaust leak where the rear manifold and crossover bolt together (I unbolted it but didn't get lined up just right). The trans has seen better days but its not too bad.
So I got 4 total runs in and weighed the car.
The car in stock form is 3390 lbs
It was pushing low to mid 90 degrees outside too. So it was pretty dang hot out.
1st run was a 15.7@85mph
2nd run (BEST ONE) 15.6@86mph
Put a K&N cone filter on. They had just prepped the track for the 6 second cars that were about to run so it was way too sticky for the little 3.1. So launching just like I was before it bogged out and fell on its face. Car really felt strong on the big end but my 60ft was a half second slower then the 1st 2 runs
3rd run 16.1@87mph
4th run 16.1@88mph
I think a 2 people got a vids and pics of it running so if ya could send it to me or post it that would be great!
