it was my first time running my 87 l98 corvette at the track. i only had a chance to get 3 runs in and the best i could pull was a 14.2 i was hoping to break in the 13s.
my mods are performance axle ratio, bbk rammer intake, stage 2 chip, mt drag radials, decatted exhaust with headders and a fresh tune up.

here is what the timeslip said
reaction:0.828
60ft;2.1
1/8; 9.08
1/4: 14.2
mph: 97

I think from factory the time is 14.4

Temp, humidity, DA have a lot to do with how fast the car runs. Fill in those blanks and that will determine whether a 14.2 is a good pass or not. Summer in bad air could tack on an extra 1/2 second in travel time down the quarter.

My 92 with bolt-ons, tune, and terrible tires would run low to mid 14's all day up at Pueblo Motorsports in Colorado. Was told though that because of elevation there, at sea level I should be about 1 second faster if not better in the 1/4.

When my 87 was stock it ran 14.1s. Your 60' times suck. Loosing about .2 there. Spinning tires ??

Work on your 60s and you may dip in the 13s. Id say you are right about where you should be other than that.
These were 14x sec cars stock thats it.

No need to air the tires down either that can hurt you also depending

Stage as close to the starting line light as possible.
That is, creep into the second light and lock your position with the brake.
Launch when the last yellow lites.
You'll cut lots off the reaction time and your 60' will drop as well.

No reason to make big burnouts.
Just a quick spin to clear any dirt off

FWIW Reaction time has nothing to do with the other times. The 60ft, 1/8, 1/4 etc. don't start until you break the light beam.
But as others said, your 60ft leaves a lot for improvement. As a rule of thumb, for every tenth you drop the 60ft, the overall time will improve 2 tenths. With drag radials you should be able to get into the 13's pretty easy.
Have fun, practice, and get ready to start spending money on this sickness of making the car a little faster!!

That's about right....like the others said, that 60 foot could be lower bringing your ET's down, but mph is pretty good for an 87 and that is the most telling thing about the vehicle's power.....my 85 when I first bought it in 2001 (completely stock) barely got into the 14's with a 2.0 60 foot but it would barely squeeze out 90mph....I think it had a clogged or broken cat conv. at that time as well, but anyway.....you get my point....seems about right.....

With your mods on in "good air" you should be in the 13s.

When bone stock in August at Englistown (near sea level) my '88 ran 14.1s with 2.1-2.2 short times.

If you know your launch weight I can calc. CHP from your trap speed.
If you know baro & air temp I can calc. corrected times and trap speed.

In reality, to improve your et, you want to stage as far away from the starting line as possible. (Shallow stage).... hence, light the top bulb, then slowly creep into the 2nd bulb, the second it lights, you stop.

This increases the roll-out, which is the distance your car has to move before hitting the start line, hence you will have an improved 60 ft and et..... a lot do not know it, but that little bit of running start into the start line is worth just about a tenth off the 60 ft time.

Reaction time is reaction time, rather you Deep or Shallow stage, you have to train yourself where you leave off the lights for your car to hit that starting line. With street tires, its real hard to be consistent, because varying amounts of spin means random amounts of time to get out of your roll-out.

For a low 14 second car with 2.0+ 60 fts, its hard, your car doesn't react quick enough to typically leave on the last bulb.... you almost have to move off the middle bulb.

Reaction time does not effect your ET.... your et starts "after" your reaction time is accrued.

Beach Bum

As others have said, it really depends on the Air you raced in.... but late June is a horrible time to set personal records due to Summer coming into full force. Tell us where you raced at, and the approximate temp when you raced and it'll tell us a lot.

But, as a note, you did great for your first time out.... you didn't break anything and your et is somewhere inline with your MPH. That's a good start.

mike jab

it was 22degrees celsious and low sea level if that helps, im hopeing to break into the 13s next time!

mike jab

do you guys think a 1.8 60ft time is achievable in my car?

65Z01

OK, so 22C ~ 72F.
What does "low sea level" mean? Does that mean low baro or hi baro??

Were you launching off idle or did you raise idle up to near stall RPM? Launching from higher RPM will help short time and ET.
If you have a stock TC (~1,500rpm stall) you will need a 2,000-2,400rpm TC to drop into the 1.8s.
I was running a 2,000rpm TC when pulling low 1.8s; you could just "feel" the car stressing to launch...

BTW, am I correct in assuming that you are outside of the USA?

BTW, here are the equations to normalize data for temp & baro:
ET = ETold * Cet
where: Cet = 0.9986 + 0.0095 * (CorrBaro - 29.1) - 0.0002556*(Temp - 35.0)

MPH = MPHold * Cmph
and: Cmph = 1.0003525 - 0.00975 * (CorrBaro - 29.1) + 0.0002667*(Temp - 35.0)

Note: these are English units, i.e. temp in deg F, baro in inch of Hg

Also useful:
HP=(MPH / 234)^3 * Weight
Here: launch weight is in LB

I agree that you need to stage as shallow as possible. After setting the pre-stage bulbs, bring up the idle RPM as possible and inch forward till you just barely trigger the stage bulbs. On the 3rd yellow swap feet and watch the short time drop. I think that with your mods and decent air you can drop into the 1.9s and 13.x range.

What tranny, Auto or Stick. If its an auto I'd say no, if its a stick maybe. It depend whether you can plant the power and hook at the RPM you'll need to run a 1.8 60.

barney c4

you can goggle what stock time shound be ... 13 .1 for a 93 . i chipped my plus it has 6 speed manual . hauls *** .

mike jab

the car is an auto with the 307 rear gear ratio, hopefully i can lower my 60fts next time, ill try heating up my slicks next time!

91monsta

my 91 stock with 2:59 gears ran 13.6 on a cool day with no wind with me preloading it as much as i could.

91monsta

mike it took me like 20 passes to get this time by the way. just keep working on lanches. try pre loading a bit to help with your 60 ft time. i got mine down to a 1.80 sec with less mods so i dont see why you could do better with some work at the track
