How often do you redline your car?

'98 rolla.

redline won't hurt your car if you do it smart and not that often. by smart i mean, not when the engine is cold or under other harsh condidtions. i have only redlined my subaru a handful of times since i have purchased in march. if have a car with high mileage, redlining could blow the motor easily if the car was not taken care of properly. think about the car you are driving and the engine. most toyotas are meant for economy and not performance.

I redline mine everytime I hit the entry ramp on the way to work. Helps clean them plugs off .

But like many mentioned - Corolla is not a performance car, there is some safety cushion built-in when they engineered the car - but you also have to do your part to protect the engine.

- run the correct oil viscosity
- make sure the car is mechanically sound, engine in good shape
- don't hit the redline until the car is warmed up
- make sure the road conditions can safely warrant a run

If those are all met - I don't see any problem at all hitting the redline - OK, running up and leaning on the rev limiter all day - NO.

But since the 8th gen is good on low end torque - I find that 99% of the time, runs up to the redline are not neccessary - you won't gain that much. The Matrix is another matter - engine is pretty gutless below 3500 RPMS - so you got to drive the nuts off the car, fortunantely - the engine is rather rev happy, as long as I'm running decent gas in it.

egh! its blows out the rings pretty easily. from my experience.

what about civics then? those little things go way past the redline. are corolla's engine lacking the "vtec" capabilities? what are the differences in these relativelly close engines?

Probably how much extra rev buffer they put in during the engineering of the engine. The 1ZZFE is pretty balls out tuned from the factory. Hondas have a reputation for having a little extra left that you can eck out and being rev happy, depending on the model. Most modern engines are pretty much optimized from the start - that's why it takes so much money and effort to realize "big" power gains.

Heh heh, every-single-day, and at least twice-a-day. Car has almost 70,000 miles. Have been running Amsoil ever since she was in her tweens. I do regular preventative (not repair) maintenance.

But lately I've been hearing a stutter or two (backfire maybe?) at WOT. Gonna have to look in to that.
