How often to you "wring out" your vehicles?

every day sometimes multiple times, I do a lot of highway driving for work so its not unusual to put 6-700kms a day on the car and passing slow moving cars on single lane highway is scary so its usually downshift to 3rd and hold my foot to the boards until I've passed and am back in my lane.
 
Every couple of days. There are three spots where it can be done without worrying about the police being around. One is on a exit ramp that goes across a bridge then down a pretty steep hill and a rather sharp left turn at the end of it. I've gotten to 110 mph headed into that left turn that realistically shouldn't be taken much faster than 55 mph. If that bridge was not so bumpy I bet I could get up to 130.
Now there is a super straight stretch of a road nearby that is perfectly straight for 2.8 miles ! I bet I could hit 155 on it. But one huge consideration.. Wildlife. Deer. I totalled my Fusion going 64mph on that same stretch of road. Deer came hauling butt out if the woods. Couldnt imagine hitting one going 100 plus. Two other spots will remain unidentified

But fun. Places where our police hide on interstates.. Authorized crossovers, exit ramps, behind bridge supports, and guard rails in spots too. Know where those are in your normal driving area then you know where they can be.
Now I usually just drive 7 to 9 mph over about 95% of the time. The 5% is just for kicks. Also I make sure NO other motorists are around. Because if something happens it will be just me involved. No one else. The spots on the interstate are places where there is a hill with a lot if trees between my side of the highway and the other side. Zero way to cross over into the other side.

I just don't know how you drive a DOHC VTEC Honda without making it scream daily.

7k is AOK.
 
Lol is this even a question? The TDI is driven hard every day, gets floored countless times a day. Sometimes you've just gotta get that pedal to the floor to get it moving without a lot of turbo lag. It redlined at somewhere around 4,500 rpm I think. It loves being driven hard and it gets 35 mpg driven hard. Can't complain about that.

Correction, just drove it to the grocery store. 4,250 RPM limit! Even in sport gear which surprisingly didn't make it rev further? Sometimes in certain conditions it'll rev a little higher but that's not where it makes its power.
 
In our MDX, you can hear the intake manifold's second stage come in at 3,600 RPM, and then you can hear the big intake cams come in at 4,400 RPM. It's a real symphony of sound. When I do drive it (it's my wife's primary car), I do rev it up and let it sing.

Our CR-V is a little less rewarding. It has Honda's "economy" VTEC system, which closes one intake valve at low speeds to save fuel, rather than giving larger valve openings at higher speeds. Once you're accelerating, there really is no change in pitch or tone or "oomph" as it rises through the rev range. It's really a low-to-midrange engine, anyway. I rarely hit 3,500 RPM in daily driving--most shifting is in the 2,500-3,200 range.
 
I usually do a decent pull through second gear at least once a day. There's a couple places with really polished pavement so I turn of the TC and play at the limit of wheel spin all the way through.

People do that ALL the time in Montreal, even though it is illegal to speed up to prevent someone from merging.

It is pretty funny, because when people pull stuff like that they totally don't expect the Fit to have enough "get up and go" to slip past them.

The iVtec kicks in and it is almost like an 80cc two stroke dirt bike that is hitting the power band as it winds up to 6K rpm.

I like to do it only when the situation calls for it, about twice a week. I feel good about it, knowing it is blowing out a bit of carbon and actually using a bit of the cars intended "performance" as I nanny drive all the time.


I like how Quebec has the lanes painted where you aren't supposed to change from the left lane to the right where there is traffic merging on. I've never seen that anywhere else. But anyways, my Challenger gets run a little when I'm merging onto the interstate, although I never run it harder than necessary.

With a 420 RWHP 6 speed Trans Am and a 310 WHP Supercharged Grand Prix, I will let you decide how often I lay into them.

When I am towing with the truck it sometimes has to be, but that is what it was made for!
 
I don't bounce my Subaru FB20 off it's rev limiter, but the go pedal is mashed to the carpet often. It's not the most powerful beast.

Many years back when I was in Missouri I drove from Saint Joseph to Cameron (about 30 miles) was doing 115mph+ I wasn't exactly sure how fast I was going as I dropped the needle.

Didn't see a single car, and for the most part the drive was perfectly straight shot, no real turns or anything. Just a dark night.

I miss that car, it died a few months later when the oil pump failed in traffic. Was a 96 Bonneville 3.8 Series 2
What was the speed rating on the tires?
 
I used to on my Maxima 5-speed. But I don't bother with the Acura TL or the minivan since both of them are automatic. It is just not the same.

Mostly, yes.

AFAIK, it's mainly certain performance engines that still need it, plus cars that are neglected, get bad quality fuel, or do a lot of short trips.
 
I think the recent trend towards low-tension rings (which seem to load up with oil easier) make the Italian tune-up more beneficial than it perhaps once was, at least on certain engine types. In other words, you want to work the engine so that the rings continue to move freely in their grooves in the pistons. When those rings start to stick (due to not enough exercise), that's when you get the oil consumption issues that some engines are known for.

It was particularly bad when powertrain programming didn't really force or allow for a lot of engine braking during deceleration. You didn't get a ton of vacuum to work with. Now that powertrain programming more commonly uses deceleration-triggered fuel cutting, you get that difference in forces on the piston rings (pressure/vacuum) to keep them moving free.
 
Only after the engine is fully warmed up. Since the vast majority of my trips are less than 20 min I take every opportunity to run my little spark hard on trips longer than that.
