Ok here goes, this person said it just stalled at the stop light and then the oil light came on, Freeze data was at 9,079 rpsm over-speed condition on this type-s.
I'll let the pics explain the rest. ENJOY



NOW THE BLOCK




It took the tech almost 1.5 hours to throughly clean all the metal out of the intake manifold alone. There were all kinds of pieces of metal in the oil pan also...
And the best thing is Acura paid for a new block and head assembly...One time only. Next over rev is his responsibility.

 

Damn Zach, gotta love that ECU. 9k did that though? You would hope for stronger internals.

 

Internals were fine, but the stock valvesprings will not handle the revs.

 

greenbean i pm you

 

9rpm hmmm. This has to be around 9700+

 

No ecu upgrades, it was a mis-shift...or so we think....He finally reported to me he was slowing for a stop light and went from third to second with the intentions of chirping the tires when letting the clutch out. I think there was to much momentum and it went all the way to 9,079 rpms....I have ridden with this particular guy once.
it could be true.

 

yeah, the older RSX use dual valve springs, newer use single valve springs with stronger material, what year was this type-s?

anyways....barely over 9000 RPM is hard to believe, i would like to think that the K20A2 could handle just a little more than that.

It is not the simple fact that it hit 9000 RPM, it's how fast it was spun up to that speed. If the idiot was trying to chirp the tires on a downshift, I bet it floated the valves instantly.

 

Im sure Zach aka Greenbean will get to the answers as soon as he gets home. Just got a call from him out shopping, so soon replys will be answered.

 

Holly smokes Doubt he'll do that again...

 

Thanks a bunch for your help BEN, I have the new 256kram in right now and yup, yup, my puter is a lot faster. I guess the old 127 couldn't keep up with the cable modem. LOL.

I think he did float a valve, it is an 03 RSX-S....It was spun up fast, the ecu will record the freeze data when the engine goes over fule cut, @8,100 rpms...but the vehicle speed sensor was at 44-mph...In driving mine around town, 44-mph equates to nothing close to an over-rev but if the engine was forced and had enough momentum than when the tach went past 8,100 rpms the ecu stored the code and the data. When in fact the spedometer could have registered more than 44-mph. Anyway...two of the valves are crammed into the head like a damn hydrolic press(really fast piston) punched them in. Go Figure

 

Could he have tried for 1st gear???

BTW, im glad i could help with the computer

true that.

chirp gears on a downshift......i bet this guy was setting up for his drift. lol

 

Thats ok. He is actually talking about getting a WRX, and that was before this happened.

 

He should get an auto WRX becasue Subaru won't cover that BS. That's pretty friggan nice of Acura if you ask me.

 

wow. that's impressive damage for only a 1k over-rev.

chirp tires on a downshift? why not just hit the brakes to chirp the tires? why would you want to engine brake your way to chirping tires?

it's nice of acura to cover it

 

doug from hondata has tested the k20a2 well over 9k in the past maybe even hit 10k. the jrsc regularly makes it's way up there.

 

I think there is more to the story then we know...But we may never know...All I have is what the ecu recorded.

 

I think it just occurs on over-rev because the rpms shoot up so quickly....9191rpm@69mph did the same thing to my K20A2, two valves and two cylinders.

The ABS should be reactive enough to prevent that.

I don't think the ABS would have been active since the brake pedal was not depressed.

ABS will not stop the motor from over-revving.

How long does that data stay in the ECU?
