Anyone blown a stock boosted motor yet?

Holy fuck man!!!

Damn...were you dataloging by chance? I am curious if it was indeed an over rev or if something blew as a result if the tune or somethig else.

Is this the first ever failure on an avo charged engine? Who tuned it and what were your mods? Hp/tq and oil temp at the time of this failure? Oil grade?

I really wish I was. This was on my third lap of the first session of the day and I was just starting to get myself, the brakes, and the tires warmed up, and was about to start the first real hot lap.

The car was tuned by James @ HRI. It was pretty conservative. None of the other three cylinders showed any sign of detonation or anything. Previous logging showed solid fueling and no knock. So I doubt it was tune related (except for increased rev limiter).

On the AVO base map (pre-James) it made 250whp at 8psi. Running 5w-30 Redline. Oil temps weren't logged. But as above I was only a few laps in, so they probably weren't very high. Pretty sure it wasn't a lubrication issue.

I'm at 250 on a conservative tune as well, but I'm on 5.5 psi. What was your tq power output? And mods if you don't mind me asking? I think you might be the first reported failure with an avo kit.

Please list what kit you are running and what tuner.

Hope you get it running again soon.

Thought he already did? I thought he said delicious flash and go was the tune.

ah my bad. I saw King Tut's post and thought he hadn't posted it yet. Didn't realize it was a few pages back - thanks.

Edit - always puts your mind at ease when you read the same kit and tune you are about to put on your car blew up anothers motor

Going with JDL's gt2867r but will be on e85 and F'N'G tune from Delicious.

Not saying it was but the last photos looked like over rev ones I've seen before. Either the valves float, the rocker arm breaks or the wrist pin pull out of the pistons at high rpm since they are NOT boxed.

From what he described that's my thoug as well. Sucks either which way, but hopefully it was just that and not the motor catastrophically failing because of the strain from boost...

Mr. Aaron Chambers,

At this time, we have gone above an beyond to support you, taking care of all your requests for updates to your tune and diagnosing idle issues for improperly installed components at no charge to you.

Now you are stating a "bad tune" caused your engine to fail, but you have failed to mention you worked on your own vehicle the day before your engine blew. Did you maybe forget to hook up a vacuum line? That would cause an over-boost condition. You did state that after working on your vehicle it was a LOT faster, which it should have not been any different then before you worked on the vehicle. This leads us to think there was an over-boost condition that you brought on by an installation error.

Also if you really had a problem with the tune, you would have not come back for another tune after your engine blew, correct? But yet you came back for another tune from us on your new engine.

I am sorry but purposely going out of your way to bad mouth us behind our backs, online, on forums, on Facebook is uncalled for. We have been more then generous and at this time we will no longer support your tune, or anything to do with with your vehicle.

Furthermore if you have a problem with your CA-Fi unit please contact the manufacturer directly.

Regards,
William Knose

Can you explain to me how you guess that you over revved? You either did or you didn't. You had a rev limiter in the tune I am guessing. Did you do a money shift?
