earlier today sum stupid bmw z3 kept trying me so w/e i dropped it into third then when i was going to drop it into fourth it went to second reved up to like 8k rpm(just to add the bushing on my shifter linkage are worn out so my shifter is really loose) so what sould i be worring about the motor still runs fine but just seeing if theres something i could check.

 

Knew a guy that did that in his stock y8. He threw a rod.

 

dude its a z3, dont even try

 

yea but my motor still runs fine well i havent floored it since then and btw its a D15b7

 

If it still runs fine then you got lucky.

 

i used to rev my singal cam d15 to 8k and it was on a 150 shoot... lasted like 5 months or so

 

can't be good.....might not notice anything now, but on the long run, it might have shortened the life of the engine. This is why u get a B and then u can rev to 8k+ no problems

 

Its just a d15b7.... its probably fine, but if something goes wrong later on down the road, you can blame this and then get a b18 or something, or just rplace what needs replacing since its cheap anyway. But if its running fine now, dont worry about it for now consider yourself lucky

 

dude, it's a z3.

you're engine is fine.

 

a gutted hatch with a strong single slam, in my opnion could keep up with a z3. Also to consider most z3's are drivven by pusseys, and are usually automatic.

 

smoke bmw z3's all day

then again........................turbo d16z6 coupe

z3 arre ****, why does everyone think there fast? bmw's are slow

 

You guys were probably racing the slow ones. There are two flavors of Z3's.

Weak sauce 4 cylinder and then there is the M. Same inline 6 that came in the M3.

 

lol your lucky if nothing happend.... b7's redline at 6200 and you took it to 8k?? im surprised yours lasted.. along time ago my friend did that but only to 7.5k and threw a rod right thru the block... but gl

 

8k isnt that high for a D (but considering its a b7 than you might be pushin it)

 

its fine...im running my y8 with a chipped ecu i borrowed from my cousin...ran it to 8k a couple times just to test it out...nothing happend...motor still runs like a champ...though it was stupid of me dont try it haha....

True but the OP's problem is that he mis-shifted at redline so in any motor it will shoot pass the limiter.

OP: If your car still runs normal then you are lucky but there is probably some extra wear because of it.

 

I rev my D16z6 Turbo on stock internals to 7800RPM all day long

............ no. maybe the one u raced was, but most bimmers are fast factory.even sum dood old man in a 760 can smoke u while he is drinking his morning coffe and not even notice he raced u

 

If you don't hear any popping, clicking, or thunking by now it's fine.

I put my GTI in at about 9k which backed off to 8 or so b4 I clutched( consider this is a 6.5k redline) when I misshifted and it was fine.

Sometimes it doesn't hurt, sometimes it does. If it does you'll hear it or will be losing oil or something...you'll definately know about it.

Don't worry about it if you don't hear anything or aren't losing oil, coolant, etc.

 

it's fine for now, but start saving for another motor. my old d16a6 lasted 2 months after it revved to 9.5k+ a few times (the previous owner told me he did this AFTER i bought the car ), then spun a rod bearing. also, in another friend's a6, he would rev to 8k when racing (though i dont know why), and his motor lasted a couple months like that.
it'll be alright for right now...just keep an eye out for metal shavings in your oil.

 

Yeah, if you ddin't **** any parts or hear any parts about to **** themselves out of your motor then you 're more than likely fine.

 

what i can not understand is how your computer let you go passed 6800...

 

i've ran my B7 on a chipped P28 and revved to 8k for a few months. nothing really happen. its kinda pointless when the motor makes no power stock to that rev. motor stops at like 7k with power. atleast get underdrive pulleys. lighten flywheel. diff. valve springs and retainers. and header back exhaust. maybe a B16 throtle body. and you should be able to rev.

The ecu can only cut fuel to stop the motor from revving. It can't however stop the motor from revving up when the drivers messes up and shift from say 3rd to 2nd while meaning to go to 4th. Going 80-90mph and shifting to second will have the motor spinning quite a bit higher than the stock rev limit.

Yes, it can cut the fuel so you can't go past there, but engaging the clutch when you're in too low of a gear for the speed you're going is mechanical, the computer isn't involved at all with that, so it'll cut the fuel as soon as you engage the clutch, but there'll still be that time where it's the danger zone/redline.
