race cars (both drag, and roadrace) have to rebuilt every so often because they beat the crap put of the engines in every race, what about normal people that run the **** out of their road car every weekend?

Ill drag/ autocross my car every once in awhile (99 Si), but the major problem is the way i drive on a daily basis. I want to drive like an old lady, but its just not going to happen. Im not going full tilt all of the time, i just like to accelerate quickly. When i accel its at probably 75 percent throttle and then i shift at 5 or 6. now my question is what can driving like this do to my engine?

 

I got my 94 teg @ 60k miles, I am now at 155K and except for when im trying to save gas, I make most shifts at redline. I recntly did leakdown, and was 2% in cyl #1, and the rest were at 100%.

 

if you drive it hard, it is very important to realize a few things:
you need to be very diligent about maintaining it.
and it WILL eventually break.
If this is your only transportation,
you might want to think about getting another car to beat up or getting a bus pass

 

Here is what I'd do: Push harder during autocross, and try to get the best results you can. The reason being, I've found that when I do good enough in a competitive environment, I don't feel the need to drive hard on the streets. My car barely hits 4,000 rpm on the road except in rare situations.

 

Same here. Driving home from a timetrail, I'm "done" for a while, feeling no need for speed.

 

all that romping will add extra stress but if you maintian your car you wont really run into that many extra problems you should attend to thinks like oil changes sooner though.

unless your like me and trying to kill that lil D motor
I'm on 5000 miles 1 autoX 1 full open track day at PIR same oil bet my motor loves me

This isn't entirely true.

The teams that rebuild often do it because:

- The motor is only built to last the length of the race - or some other pre-determined amount of time

- At the highest levels of competition the difference in performance between a fresh motor and a motor with 1000 miles on it can be the difference between winning and losing

Also note that with the exception of CART, F1, NASCAR and a few select high-level sports car teams I am willing to bet that the majority of the professional racing world DOES NOT rebuild/freshen their motors after every race. They probably do it a few times a season in conjunction with a rotation between a few motors.

 

My friend said it best "driving your car on track is like masturbation for your car"

 

One thing I do know is that after a track event or a night at the dragstrip my cars have always run smoother and cleaner on the ride home than they have at any other time.

Working the engines once in a while clears them out and makes a world of a difference in how they run.

you should get cylinder 2, 3 and 4 looked at, if you're seeing that much leakdown

That's a great quote but what happens when you "over-stimulate" your car? You can't give your car a few pills of Viagra, you will actually have to replace/rebuild the motor.

 

lol....oh yeah, I guess I didnt word that right. my redline shifts also dont come from canyon carving
