Okay guys, can this damage anything? Bouncing maybe 3-5 times off the limiter? Theoretical or actual experiences welcomed.

 

you didn't hurt anything.

 

Many actual experiences. I do it almost every time I track the car. It still runs.

 

thanks guys...it is one hell of a sound i might add....

 

Guns, wait till you arent running it on the stock motronic and hitting the limiter is 3 loud cracks (much louder than gun shot) followed by a large fireball.

 

I'm not going to ask how you know....(any pics?)

 

It shouldn't hurt anything, it's there for protection. That said, it is pretty jarring, and if you're timing belt is about to go because it is neglected, I could see how bouncing off the rev limiter could be the last straw.

 

Living on the rev limiter is sometimes "the order of the day" depending on the course and your gearing. Took me a good while to get comfortable with the idea that it happens sometimes, and then a little longer to accept that is also sometimes the best choice...when stuck between backing off or upshifting with too little real estate left to make it worth it.

I've been processing the theory that raising the limit a couple hundred RPM's may be one of the few good reasons (or maybe the only) to ever chip an NA

NA racers do some interesting things to stay away from the limiter, the cleverest among them, IMO being to transplant an S or S2 transaxle, which features Turbo ratios in the first four gears, but the 3.89 rear ring and pinion...gives you something like 8% more speed per rev in the low gears....handy in some of the places you would otherwise be on the limiter.

 

It don't hurt nuthin but your times. If you can hold the throttle at the point just before the rev limiter kicks in on those courses that you are running out of gear, but not enough room to go ahead and shift, you will make better time. Hitting the rev limiter is like backing off almost 500 rpm speed wise because it lets off completely then comes back then lets off completely then comes back. It takes a LOT of practice and you have to know your car really well to hold it at the point just before the rev limiter kicks in. It is best if you can do it by ear. That being said I am seemingly always surprised by the rev limiter when I hit it.

 

When I first got my 951 it was completely stock, nothing had ever been done to it. It even had the stock cell phone and cassette player in it. I used the stock rev limiter as a shift point. But later on after chipping and running much higher boost I stayed away from it. I didn't feel it would really 'hurt' to hit it but just figured I'd be a better driver by learning where it was without looking and staying under it. And very true, on track it'll kill your time if you're timing.

The fatcory Motronic rev limit is a very good setup. It cuts both fuel and ignition.
If you are hearing a loud crack only - VERY, VERY bad for your turbo.

 

Nope, I really didnt shoot any video or many photos of the car while it was out this year. To busy sorting out reliability and driving it. Next year,,,

 

hitting the limiter is no big deal.

if you're at the track, it's faster to hold the rpm JUST before the limiter kicks in. Bouncing it off the limiter actually cuts off the fuel/ign and there is accell/decell as it shifts the weight around.. not good when you have to corner at the same time.

 

Over 355K miles on the daily and I was hitting the rev limiter last night (playing in the rain) quite a bit. Motor is still fine. I never saw it as a problem.

 

WOW......I am scared to even get it close to redline let a lone bounce off the rev limiter.....I guess judging by every ones response its no biggy.........I guess I just hate to hear the enegine rev so high....I always think something is about to break..........maybe I should just do it and get it over with....and once I realize nothing is going to break (at least I hope that was I realize) I will be less scared to push the car to its limit.
