What is the top speed on an 89 Corvette Manual 6 Speed with an L98 Engine?

Answer 1

Oooh! This question leaves many possible answers open. So many variables. Do you just want the "official" factory salesman answer for the car at time of sale? Which is probably something vague about being in the >150mph area. Plus I note you are much more likely to get solid answers for 1/4 mile drag acceleration times than for true top speed. Because true top speed is more about the following factors especially #1. (In general there a bunch of questions about how stock the car, all accessories, and maintenance are. Plus a bunch about the conditions of the speed test.) #1 How brave are you? All sorts of risk factors. Do you chicken out when safety issues go critical or keep you foot to the metal? Do you blow the engine to find out? #2 What is the speed rating of the tires? Stock tires can blow before the car tops out #3 What is the condition of the car in general? New? Or a rust bucket with prior collision damage to the frame? #4 How is your tune up? Recently and well done? Are you using stock or premium racing parts for things like spark plugs? #5 What is your fuel? #6 Is this a drag race with limited space to accelerate? #7 Is this a Bonnieville flats time test like situtation? Straight course with "unlimited" room to accelerate -- but with wind factors cancelled out by two way timed runs? #8 Is this an oval track race? Is it banked? #9 Is this an irregular course race with lots of curves, corners and variable road surfaces? #10 Is the speed measured uphill or downhill? #11 Is this a sustained speed test where engine part friction heating places limitation on performance? (This question will make a big difference.) #12 Is this a fuel limited race? (OK they exist but this is probably not in the spirit of the question and it goes towards the sustained speed idea) Or are you looking for the speed attained by some specific automotive review team? Mind you there can be some huge differences between Popular Mechanics and Consumers Digest
