Anyone blown a stock boosted motor yet?

It's a give or take on this. Since the car is still in it's first generation stage anything can happen. However, this engine should be able to handle the small amounts of boost most of these kits put out. If you are worried about the boost you might want to wait for the new STI version of the BRZ. I believe it will have more power but still no turbo(?). I think Subaru is on to something :p

I know who the tuners were for all of these, but I was going to leave the tuners out of this conversation.

The only one I know of that was definitely on E85 was @nelsmar. I updated the ones that I now what fuel they were on. If anyone knows about any of the others feel free to post it up.

Yep, cost me $9000 to pay off the loan and get rid of the car. Shop didn't refund any install money or apologize for the negligence. Same shop installed the premium stage 1 kit from Full Blown on another widebody car out here. It had cooling issues and never really was 100%. Owner of that one is now doing a swap due to the motor blowing.

I had that thought reading through too. But let's do some analysis I think you'll find that it's quite easy to avoid worry with FI.

We (currently) have nine motors that blew:

2 during development

4 Turbos
1 from mechanic negligence
1 from bad tuning
2 unknown

3 Superchargers
1 from a rod defect
1 on a brand new barely-released Sprintex kit
1 from a bad tune

Notable Absence
Not a single CARB-tuned supercharged car has blown (Innovate, Vortech, nor Jackson)

Before jimmies get rustled, I want to make it clear that I am NOT saying that it's impossible to pursue worry-free custom-gains, and I am not saying that turbos are inherently evil or dangerous. It just takes more knowledge and due diligence to pursue custom gains (whether that is through learning yourself, or deciding which shops/tuners to trust).

But JoeBob ForumLurker might read this thread and be thinking, "Maybe I should sit out from Forced Induction forever because there seems to be a lot of risk."

And I want to say to JoeBob ForumLurker that running a CARB-approved tune on a CARB-approved kit is incredibly safe. The Forced Induction swimming pool is large, and just because engines have blown while exploring the deep end does not mean that the shallow end is dangerous to you.

That is why I like the poll at the top of the thread where people can realize that blowing your motor is the minority not the majority.

I see, just thought a tune/tuner being the most important, it would be good to know which tuner was responsible and what they did for my own set of "what not to do's"

And therein is the problem. We shout from the rooftops that a good tune is "100% the only things that matters" but if you try to gather data on potential untrustworthiness in tuners then everybody clams up because of the justifiable fear of creating a witch-hunt.

Likewise, people bend over backwards to justify the greatness of their own tuner. When someone's magic gives you 50% more power, of course you love them! Consequently even when you hear somebody say so-and-so tuner is great, it seems like there is a 50% chance that the same person will turn around and tell you how their tuner screwed up their tune in the past and could have caused serious damage, but then everything turned out fine so it's all fine and the tuner is great!

I'm not pointing fingers, it's just maddening trying to gather the information required to make responsible decisions about this kind of stuff.

The point of this thread is hearing about the bad side of things. In reading the bad things that have had happen to people ,I believe, you can make a better choice. If all you hear is the good stuff then no one would ever improve on things.

Btw I believe that tuners should be called out in order to help people not make the same bad choice.

Thank you all for sharing.

I updated my list with what I believe to be the tuners of each vehicle.
