How Fast

[BOPIII]

Does any one know how long it would take to accelerate to 60 MPH in a 1988 Vette with an L-98 engine Automatic Trans if you were driving at a steady 40MPH and went to wide open throttle. Any personal experiences or if you have any Acceleration data i would apprecieate it. Thanks

my car roughly covers 0-60 in 4.27 seconds

Let me see if I have this?

You are cruising at 40 MPH currently, you jam it on the gas/throttle (which is now Wide Open Throttle, WOT) and you need the time now on how long it takes to change from 40 MPH to 60 MPH.

I really do not know where this could be obtained besides some test track configured with timing devices

I would guess then 1-2 seconds

Acceleration Estimate

Does any one know how long it would take to accelerate to 60 MPH in a 1988 Vette with an L-98 engine Automatic Trans if you were driving at a steady 40MPH and went to wide open throttle. Any personal experiences or if you have any Acceleration data i would apprecieate it. Thanks

Car and Driver used to publish acceleration graphs from 0 - 60. If you could find one from 87 - 89, then you could pick off the time from the curve.

Physically, once you get to 40 mph, you can maintain that velocity as long as you want, and then resume the acceleration to 60 mph. The acceleration from 40 - 60 should be essentially the same when measured from a constant 40 or from the standing start (after you get to 40).

That would be about your best estimate (unless you instrumented the particular car of interest, which wouldn't be an estimate, anyway).

A second (and less accurate) estimate would be to find the 0 to 60 mph time, and estimate the average acceleration.

For example, if the 0 to 60 mph time was 6 seconds, then the average acceleration is 10 mph/s [(60-0mph)/6s = 10 mph/s]. Your velocity change of interest is between 40 mph and 60 mph, a difference of 20 mph. If the average acceleration is 10 mph/s, then it would take 2 seconds to make that change [(60-40 mph)/10 mph/s = 2 s]. This is a less reliable estimate because in fact the acceleration is not constant from the start to the finish - it is more likely that acceleration is less at the end than at the beginning.

In any case, these two methods are probably accurate enough for most street applications.

Any particular reason why you're interested in this range?

Why do you care how long it takes to go from a rolling 40mph to 60mph in the first place? I'm just curious. And to "wide open throttle"?!!! Haven't YOU tried it? And didn't it take, what?.... a coupla seconds tops? And didn't you find yourself around 100+ mph in a coupla more seconds once you whooshed past 60mph? From 40 to 60 you aren't even close to "wide open throttle"---more like around 1100-1200 rpms. What an odd question you've asked.

Seems like the car rags used 40-60 times as an approximation of how quickly the subject car could pull off a pass on a two-lane highway - - anyone remember regular interstate travel on a two-lane?? :L
Since that time in any car I could afford was about 35 seconds, my technique was to lay back, mash gas, & be at 60 or so when I got to the rear bumper & had to pull out for the high-speed pass!!! Prayer also helped.

You may be correct, but even in my stock 81 coupe I never worried or gave much thought to that, and I certainly do not give much though now in my Z.

What is a two-lane Interstate? I remember before there were Interstate highways, a luxury of finding a four-lane highway sometimes, but not any two-lane Interstates, only main two-lane highways with the traffic lights and stop signs on them whne you went from town to town.

Stop it right now, guys. You're telling everyone how old you guys are! :L:L:L

Hey Pseudo - You're proving Edmond's age-display point!

I said "regular interstate travel on a two-lane". Not two-lane Interstate.

And now that this poor guy is not! getting the answer he asked for, I'm shuttin' up.
