Attained 15000 rpm with my engine; no problems

As the title says, I pushed my rotary to over 15000 rpm and I didn't find any problem during ar after the run. I have had no way to measure the power output (at least not yet), so no hp figures for now.

For sure I can tell you that the engine, the transmission and everyting else survived the test, and everything was in good conditions. I could have probably run the engine at 15000+ for minutes with no ill effects, although I limited my extreme speed runs to a few seconds each.

Now for the technical part: the engine is completely stock, it has not even been opened once after it left the factory (and, in case you are wondering, it's not a race engine ). I'm uploading a video on Youtube right now taken during the test that shows everything. It clearly explains how I did that and how everybody can do that.

Now it's the turn for your insults and BS calls, at least until I post the video.

See you later.

how do you know it was 15k? not outta sarcasm, but what was telling you it was at 15k?

yes. post. another dude said 11k and that seems more believeable, but why? we lose power after 8500/9k anyways.

You do realize that one problem and the flywheel will probably cut your legs off, correct?

The factory ecu cuts fuel flow before 9500 rpm. How were you able to over ride that?

Hmm, I'm curious to hear what that sounds like..

But also, is money no object to you? This seems like a rather high risk to the whole powertrain..

The upload is not yet completed (damn slow connection!!! It is ad ADSL, but it's still so damn slow sometimes). I'll post a direct link when it's up.

As far as the "Why" question, it was some kind of a personal challenge.

I can tell you it SCREAMS, plain and simple. And you'd be surprised to know that it all costed me less than 300$. But that was with a lot of homemade stuff.

do you understand how rapidly the stress rises on those parts once you get over 7500 rpm???
How did you override the fuel cutoff?

As I said, it's all explained in the video. Both regarding the bearing stress and the problem of passing the 9000 rpm limit. If I were to start typing everything here, I'd finish by the time the video is online, so I'll post that directly.

Come on connection, it's just a few more % points missing on the upload...

upload it again on google video when you get a chance. a LOT of people can't access youtube during the day due to internet filters.

I'm not being sarcastic or anything, but I have done it too, I was on nitrous at the time, I misshifted 3rd gear, and the nitrous was still pumpin( floored it) at my rev needle went pass 10k and went all the way to where the speedometer is located ( idk what that would translate into) then it comes back no problem, if there is going to be a problem, the flywheel would probably cut my leg off by now, but nothing happened, I let her settle down, shifted to 3rd and drove off no problem

i downshifted into second too soon one time and it went above 10k rpm ( i know for sure because the revs sounded higher and as they descended it finally hit after a second) but like i said...why?

Exclamation Scatter Shield!

I certainly hope you have a scatter shield to protect you from the shrapnel that can rip right through your car if a mechanical failure were to occur from such high speed engine/transmission operation.

Finally here it is.

Now just watch it and you'll understand how I did it all.
