Is this Bad? - Honda Prelude Forum

On my way to Vegas, me and My cousin who has a CLK 320 decided to go ahead and drive 100+ the whole way. At one moment, I decided to turn it up a notch and accelerate my engine further. I hit 153mph and when we had made a pit stop I turned off my car and turned it back on and the air/fuel ratio was on lean instead of rich. I also noticed that my clutch had a lot of wear because it didn't feel like it was griping, anyways, my question is, driving at constant speed of 100+ for 2 hours, does that do any type of damage to your vehicle?

It wears your motor out alot faster....Just cause you car can go that fast, doesnt mean it can handle it for that amount of time.

Did it cut out at 153? Ive only gotten mine to 135... I was worried about my half bald stock tires I had at the time...

ok try this.......drive your car for a few miles in 1st or 2nd gear sitting about 7700 rpm w/ cruise control on. listen to the motor.....same effect.

I was driving my car, the Benzo speed gov. is at 133. But I think I could of gone further, but I was at redline, so I decided to stop. But I only went up to 153 twice, once on the way to vegas, and once on the way back home. Man you should check out the a/f band. It gets pretty Krazy!

I've gone 140 and I haven't noticed anything wrong with my car.

lazilude909 · 03-12-2002, 06:29 PM

a/f stands for air/fuel. I know there isn't anything wrong with my engine but I wanted to know if there is any serious damage by going that fast for about 2 hours!

Nah, just don't do it all the time.

The 1st gear 7700 RPM comparison was pretty good.

The car CAN do it, it just does not prefer to do it all the time.

I drove from PA to FL 12 hours straight at around 100mph. Burnt some oil but no damage.

Just don't make a habit of it

And i doubt there is any serious damage if the car is running fine, so you can relax now

later

yea i don't like that 75 85 mph is so goddamn high in the rpms, its like 4500, i love that nice whiny noise

On highways i usually cruise and go up to 100 occasionally, i don't get too good gas mileage, and since i use synthetic its not that bad on oil consumption... u should be aight, maybe just get an oil change if your worried

Prelude Racer · 03-12-2002, 10:12 PM

well myu opinion is that its really bad .... to drive that fast for that long having the revs up that high is bad.... my friend had a integra and drove from reno to vegas 140 all the way when he came back his engine was leaking hella oil the engine got way too hot and blew out he gaskets ........... its a 4 cylinder ment to get to a certain speed fast like drag race car ... on the other hand V6s V8s can handle going that fast cuz their rpms are usually low at those speeds .....

1997ludeSH · 03-12-2002, 10:18 PM

our v6 caravan at like 90 is at 2800 rpms

Greek Lude · 03-12-2002, 10:36 PM

I don't get it. Your A/F gauge reads lean at idle. So what? Did you expect it to read rich?

pearlude · 03-12-2002, 10:48 PM

I cruise back and forth to work everyday on the highway at @80...then again that's about 1 thousand revs less (4k).. Still get @300miles a tank

lazilude909 · 03-12-2002, 10:58 PM

The A/F gauge band has a large reading from stoich to Rich, that's about 8 bars at 153!
I did not make it all the way with a full tank, I only got 260 miles till I filled up. I usually do about 330!

xtal · 03-13-2002, 12:52 PM

Please do not think that your O2 sensor means anything, it's designed for one thing: to indicicate rich or lean. 1 or 0. It doesn't have the resolution to do anything else, regardless of the voltage reading you get from it or what your guage says. The F-body and Corvette guys are all over in-car wideband o2 sensors for getting a better picture of what's going on. I wish the people who sell these guages would make this point more clear (and I'm sure most of you know this).
