Supercharged VQ37 Goes BOOOM

wow... I guess the bright side is its being covered under warranty.

If adding headers caused the AFR to run so lean that this happened it seems like the original tune was $hit anyway.

How do you figure this? Maybe it was so perfect the headers threw it off and went too lean? lol such stupid comments.

My headers made me run leaner when i had normal bolt-ons...I can only imagine what it did to that car running a supercharger...

My point was that there should have been some room for fluctuations. Adding a header should not lead to a blown motor. "So perfect"?? Seriously? If it's teetering on the edge of the leaner side of the optimal AFR, changing elevations would mess with it.

OOPS, just saw your sig. You're a stillen guy. My apologies. I saw one of those "so perfect" stillen tuned superchargers up against a GTM on a dyno. People who have installed both speak of the fitment with the stillen and how it makes you fit your car to the kit rather than the other way around.

Either way I feel terribly for the owner but why he would romp on it without a tune is beyond me.

Just goes to show he simply wanted to go fast and didnt have the knowledge. I'm not saying he had to build it himself, but to invest all that money and not understand that he shouldn't get on it until it was properly tuned doesn't add up. It's really his fault. If all he wanted was power then yea, lean it out with the current set-up. But he should have told the tuner to leave it a little on the richer side if he was planning on headers all along.

Was the tune right on the edge of being unsafe? Even when I had my UpRev Tune done the tuner eeked out as much power as he could without going to close to being unsafe.

Any forced induction car should always have one of these:

I've been reading a lot of bad things about Stillen products recently. Are they all like that? I hope the Gen 3 intakes are excluded from this bad list since those are the only Stillen products I plan on getting.

Sounds more like bad advice than a product fault from what I'm reading in the article.

It's not the charger. Granted, GTM's is better and easier to install, but it's not the charger. It was running fine prior to the header install, so it seems. My best guess is that the tune was too agressive in terms of AFR and the header leaned it out to a dangerous level at WOT. It's really the fault of whoever told the owner that he didn't need a tune, but the owner is also at fault for not knowing that a tune would be needed.

You shouldn't change anything on the car without modifying the tune. I'm not a Stillen backer in anyway, and have generally been unhappy with how they handled the supercharger deal, but this is owner error. Changing headers certainly changes the tune enough that you should not be driving on it, and definitely not making a pull.

On my S2000, the IP exhaust I had on it separated, causing an exhaust leak. The leak altered my AF readings enough that the car would have done the same thing if I had run it. That's just how FI applications are.

Believe me I know I had that AEM wideband on my WRX the second it was released. Worth its weight in gold. I feel bad for the guy though

+1. I feel like the plug-and-play nature of kits these days has a lot of people feeling nothing can go wrong, and it's not the fault of the guys running the kits, really. If no one tells you how much fire you're playing with, things like this happen.
