How often do you hit the rev limiter?
I'm curious, because I do a lot. Mostly first and second gear. 'Drive it like you stole it' quantification poll
|
Where's the "My wife made me buy a tiptronic so I can't hit the limit because the car takes over!!" voting button??
|
I apologize for that, but I can't edit the poll now...I guess you have to settle for the last option...:eek:

At least once while it's out on a run, but only when fully warm. I'd hate for Porsche to have wasted red paint like that if the tach needle wasn't supposed to touch it... Redline, though, not limiter. Apparently Type II over revs can stretch rod bolts. |

Never! Doesn't do the engine a bit of good. I often take it to 5-6,000 RPMs though. If I really stole it, I wouldn't want to draw that much attention anyway ;)!
|
I like to think of it like this: it doesnt do the engine THAT MANY bits of bad, compared to how many bits of good it does ME; its got the revlimiter for a reason.
And the rev limiter/redline are the same...at least to me. Type 1 revvs will hit redline (which is the rev limiter) and be completely safe to the internals (minus the extra wear of 6500rpm versus Joe's 6000rpm...can't be THAT much more wear, its not like I keep it at redline for seconds on end). AND, if my engine fails because I 'revved it too much', I will be infinitely less mad than if my engine were to blow up from the damn IMSB. **end justification of driving my car like a mad man** |
I hit it almost daily.
Its therapy. Its a mechanical Mozart. Its good for my soul. :) |
Not to mention with the new cheapo ebay exhaust. I've got to admit the drone sucks, but the redline sound is like....explosive..literally

Sometimes, but I tend to say bad words because I think it is lousy technique. My target shift point is 6k unless I am on a long straight road in upper gears. Then I want every RPM. Banging the rev limit probably doesn't do much harm but it is certainly not "fast" either because we are effectively stalling the motor momentarily.
Harm usually comes during a downshift in the heat of battle and zinging the throttle too far to match revs. If stretched rod bolts don't get you, cavitation of the oil pickup and subsequent oil starvation will. I suspect most BSR race car motors are damaged or killed during over-rev downshifts... especially after a long left hand banked sweeper when most of the oil is in the right front head instead of the pan. |
0 type two overrevvs for this guy :D

:D Anybody that has ever done any racing knows of what we speak. It's a red mist thing and our respective repair shops thank us for it.

Never. The engine doesn't want to go past 6000 and the power falls off abruptly thereafter anyways. I say all of this based on 'how it feels'. I've heard you should shift at a point where the following shift finds the torque peak- makes sense but I trust my ear. Now racing is different...
Oh and BTW don't forget these engines have oil starvation issues... |
If you really want to over rev an engine and get away with it buy a Honda!:chicken:
|
I believe my engine loves to go past 6000, her and I had a heart to heart last night
I mainly hit it because: -higher RPMs make me go faster, there is lots of power at 6400 -I normally build up the rpms slowly to 3-4000 and then nail it, and the rev limiter isnt far from the 'normal' cruising rpm of 3-4k (other cars slow my 0mph start sometimes) -I'm accelerating in a long straight line from 0 mph -if I didn't hit it, I would be "granny shifting, not double clutching like I should" I think most people would say they hit 6000 at least sometimes, and how different is 6000 from 6500 in terms of extra stress/wear? Plus, isn't OVERrevving going past 6500?? I don't venture into that territory, only because my ECU wont let me |
To lazy to read all the posts so sorry if this was already said. Are we talking red line or rev limiter? Hitting the rev limiter on a daily basis is pretty much saying you don't know how to drive your car. If we are talking taking it to red line then I take it there every time it is out. But I can probably count on one hand how many times I have bounced the rev limiter.
Edit: OP rev limiter isn't red line. |
6500 is where the red line starts in my '99. 6500 is when the engine bounces off of rev limiter as well...I think. I guess I never look at the tach when hitting the rev limiter
I agree it isn't 'racing style' to hit the rev limiter; you are wasting tons of time with no extra speed, but its cool...I'm not trying to get the best time of the day when accelerating onto the freeway |

I think you are entitled to laugh if you wish, I am having fun doing it!
I basically use it as a shift indicator on average 2 times a day for first gear. If its Friday, I'll give her a whirl in long 2-3-4 pulls |
Erry day! Especially on downshifts. #type2rev
|
Well, to be quite honest, you did have two type 2 revvs on the durametric. I think you need a new engine
|
I'm not finding anything constructive above 6,000 rpm and the gear ratio spacing puts me in a plenty meaty spot so I shift there.
I didn't click "never, it's a porsche why would someone hurt it like that?" because I'm quite sure the engine can take the revs, nor am I worried about offending my car. I'm old and learned to drive vehicles before rev limiters existed. I personally find the na-na-na sound annoying, but that's just my opinion. I was on a "toys for tots" motorcycle ride last December and some guy on a Hayabusa thought he was the shiz because he kept sucking in the clutch and hammering that limiter. :confused: |

When just driving (fast of course), what rev do you keep it at? I usually shift until I have the RPMs around 3k. John |
See, its exactly that. You aren't actually cool for hitting the rev limiter, but most people think you are when you hit it.
Combine that with 'it sounds nice to me, the driver' and...why not? Plus, you know the saying, 'a rev limit a day keeps the IMSB doctor at bay' |
I normally sit at 3k, city or highway. Sometimes lower if I'm just putting through a neighborhood.
|
On my 2.7 I hit the rev limiter (or redlined) almost every time I drove the car. My car had 48k miles and 12000 range 1 revs and 0 range 2. On my turbo I don't think I have yet hit the rev limiter. Btw my 986 imsb was in perfect shape. I think the single row 986 bearings need to see high revs.
|
12000 is insane, I think I had 3000+ last I checked. If my IMSB was thinking about shredding itself before, maybe I have stopped the process with my immature shifting strategies
|
Limiter one time, the first drive after I had taken it home and given it a good check-out. 6k frequently, but as it passes 6, I'm shifting.
There is a park under construction near my home. Nice fresh roads, lots of corners, and open parking lots not in use yet. First week of ownership I went out there to play. After a good 15 minutes of tire squealing turns and fast accel/decels I noticed that soccer practice at the adjacent park had stopped and everyone was staring at me. Oops. :o |
Never. I voted never not because it's a Porsche...
It's because even with a 7200 redline, just going to the 6000s puts me way past any speed limit and I can't see where I'm actually getting anymore out of the engine. The only reason to go redline is so the shift down keeps you at max HP/torque BUT you really can't do that on 99.9% of public roads Race track yes Even my usual 4-5000 shift point has me leaving the red light crowd way back until I hit the next red light. Then they pull up around me and shake their heads "It's just a Boxster - Mid-life crisis guy" Though the other day I was back roading and at the corner was a group of cyclist waiting for stragglers I went by mildly in first - no reaction. I took second up to 6k, glanced in the mirror(I'm so Vein) and all their heads snapped around to look and take in the glorious sound |
I have hit the limiter 2 times I think, once in first as I was accelerating out of a parking lot lot straight onto a deserted back road, and once because I came out of turn 7 at road Atlanta and forgot that I had downshifted to second because I wanted to get around some super slow traffic ahead of me. Each time I was like whaaaatt? Ooohhhh...
At a de I usually shift between 6000 and 6500. I am just taking it easy ;) on the street usually around 3500 if I am just easing along... |
I never have. Don't the 3.2 engines hit their peak at 6,000 RPM?
|
I can remember two times since I have owned the car, I remember the sensation and immediately let off the gas to a more normal 4K
|
I really flogged it in 2nd and 3rd gear. I never really felt the need for more power as it was always a downshift away.
|
I had over 29000 on my 01 before it blew at 89,000 with a stretched timing chain (according to Jake's admin). All were type 1 and usually were logged during fast starts in first gear.
BTW the way it is not a count of rpms but rather how many times a spark plug fired while at redline. |
I see no reason to flog a Boxster's engine up to redline in first gear, even under track conditions.
IMO, second gear is the real power gear, once you get her goin'; third gear is the kicker, fourth gear is cruisin', then fifth or sixth, in normal conditions............is just sustaining speed. I've never hit the rev limiter. Brought her to redline many times (2nd, 3rd, 4th). Empathy towards one's machinery is important, and not just in maintaining longevity. Just sayin'.............. TO |
I found 2nd and 3rd were the gears I was mostly in when I was driving through light traffic and the red line in third was my speed indicator telling me to slow down. Fourth and fifth were just to cruise and conserve gas.
So what would cause the elongated chain. Abrupt take-offs? Missed shifts? That is the only mode of failure that turbos suffer and mostly those with the x50 package and bigger k24 turbos. |
I almost never do, but this w/e at Kansas Speedway I banged it several times in the early sessions. She would accelerate so fast, I didn't have time to shift. Plus there was a lot going on learning a new track. Didn't like hitting the limiter, but got to where I wasn't doing it the 2nd day.
|
I think I would put it like this: nailing the throttle 100% from 0 mph and hitting rev limiter is probably 100% load and the worst case in terms of something bad possibly happening and is mostly for Justin beiber and other immature youngins.
The rev limiter behavior I frequently see is slow takeoff rpms up to 4k then giving 100% throttle up to redline and holding throttle at 100% through second and third. Obviously you are going pretty fast by then, but luckily my commute has lots of metering lights and on ramps. It just feels nice to grab those extra few hundred rpms up to the limiter; it's like 'stretching' the legs of the engine..for lack of a better expression |
