Why is my C5 slow?
#22
When I first bought my car it was very slow.The car sat for along time and had some bad gas and the plugs were toast(pucks fell off on 3).Do a tune up and put some fuel injector cleaner through it and beat the hell out of it on the highway for the full tank of gas.(run the tank very low to get all the old gas out.)The DR before you probably babied the car and now it is carboned up.JER

What else can I check? Fuel/Air filters? Should I have a shop check it out? Will a diagnostic test tell me anything or do they have to do a dyno on it? About how much is that (incl. vette tax!)?

Hi jah -
Change out the fuel filter, make sure the air filter is not clogged -
Make sure there is not restriction in the exhaust pipes.
With 50k miles, it's not like it sat all the time.
I vote you have a fuel system issue - if you are not equipped to check it out yourself, it's time for a trip to a qualified tuner/mechanic.

What steps do I take to check out problem areas. I think it might be the fuel or air delivery - change filters? Sorry, I didn't get 60' times, but I seemed to do well there. The other cars would pass me after we got half way down the 1/4 mile course.
Thanks

You think your car is slow 'cause you don't really believe "there's always someone faster"... once you accept this concept.. you'll be happy with your ride

Everyone is quick to blame the car......
But by what he posted (left the car in OD and left traction control on), I seriously doubt he even knows how to properly launch an A4.
If I were him, I would do a forum search on the proper launch technique.
Just for quick reference though, next time you go to the track:
1. Place the car in competition mode (you'll be happy you did).
2. Put the car in 3rd gear.... Let it do the shifting for you.
3. Put your left foot on the brake and hold the gas pedal down until the tachometer is holding around 1500 RPMs. If the wheels are slipping, then back off a little on the gas.... If they're not, then appliy a little more gas until just before the wheels spin.... DON'T SMOKE THE TIRES!!!
4. When the last yellow light lites, let off the brake and at the same time, push down the gas pedal..... Don't stomp it, but firmly press it all the way down. If you do it right, you won't "red light".
5. Hold on and pay attention to the road and the car, don't look at the other guy or the speedometer..... As you pass the finish line let off the gas and slowly apply the brakes, don't slam them on.
If you do that, I bet your track times will improve..... If not, then check out the car.
Good luck.......

Dang dude, my 84 is faster than that, my 84 60ft times are 1.95-1.98 and I always beat a stock C5 in the 60, your 60 should be I would think around 2.00 give or take a few. but don't quote me.

His MPH is way too low for it to be driving technique. The only times I had seen my MPH that low was if I got out of it during the launch because of serious traction issues. (i.e fishtailing etc)

I think you said you're in el paso... altitude's a bitch, so you're always going to be slow...... but not that slow.
I didn't see too many symptoms listed other than it's slow times/speeds; any CEL's?
I'd look at:
cats
plugs
wires
af
fuel filter

I'd recommend getting a tune up (plugs, filters, etc) and then if that doesn't get you back up to normal, see about getting a dyno tune.

It doesn't matter what his 60' times are, what gear he was in, what driving mode he was in, etc. If he's only trapping 91 mph he's WAY down on power. Like something on the order of 100 rwhp down. The car needs attention from a good Corvette mechanic. If it otherwise runs well (not rough or smoking) it has to be something relatively simple. That or somebody swapped in a L-48 while he wasn't looking!
I bet this guy is going to get the cheapest 100 rwhp boost on record.
