Let's see here...

- Run low on oil
- Run at very high cylinder pressures (12:1 with port fuel injection + 9psi on relatively low octane fuel )
- Possible (probable?) detonation on the dyno at high rpm
- High rpm, high-strung motor that STARTED OUT making 104hp/l and now makes over 150 and still revs to the moon...

Yeah, my car will probably blow up tomorrow because I'm saying this, but I'm thinking you got your money's worth out of that motor. I'm not worried.

As we say at the track after something bad happens:

"That's racin'!"

Nothing left to do but re-motor and make it faster!

I've read of a couple 2008 cars with bad bearings here that were not blown, but I think they had the "ticking" sound.
I also remember someone saying NOT to use Meth with this engine- it may have been Ronin.
Anyways, good luck with the rebuild. Isn't this going to run close to $20,000?

No offense taken, but FWIW a stock car has thrown a rod.

I'm not sure, they motor still needs to be torn down to find out more.

I do not remember seeing any bluish color.

Nope, it ran fantastic.

More inspection needs to be done, but what I posted is what I know so far. Sorry I can't give you any further concrete answers right now.

I think it does, ask the experts, 11psi is too much for these motors, and it appears 9psi might be as well.

Actually I do, the engine is 25K new! I have had several friends who's motors have blown, some through a rod, most were not so privileged where the tuner took care of all the costs, and I'm talking about some of the most well respected tuners in the world. But I agree it is good business for them, I'm glad they are taking care of me, I am not going to get into whether they should of or not, the fact is they are.

lol, I respect your thoughts, I'm sure many probably may feel the same way you do.

FWIW, Gintani never even questioned it, from the moment I called them to tell them what happened, they said, "We'll take care of it." As I said in my last post, in my long history as an enthusiast, modding, etc. for the most part when you add FI to your car, upgraded, etc. if something fails, the tuner normally will not cover all costs, some do nothing and some will find a way out, based on things you did to the car yourself, so I think they get it too.

Yes, a N/A motor has blown and the owner is on the forum but his user name doesn't come to mind at the moment. He ended up rebuilding the motor to stock displacement with higher compression. Paired with his Akra evo exhaust it sounds great.

so we have 1 N/A blown out of how many N/A .... and at least 4 or 5 S/C blown out of how many S/C?

Sorry to see your motor blow, hopefully it will be up and running again soon. The car is a monster!

cant really group all super chargers together since tunners have different methods...

i almost 100% positive ESS has no blown motoros, and they've sold A LOT of kits.

Gpower had 3 i believe, one was tightie, the other two were mentioned somewhere on the forum. if i remember correctly it was due to a bad tune but they were able fix that.

Active has 1 but good luck finding info on that.

Gintani has this one.

Of course you can group them all together, they all have S/C. They may have blown from different reasons, but seems to be pretty obvious the S/C motors are at a much higher risk of blowing up than the N/A. Whether it's tuning or whatever they are failing much more often than the N/A

whatever floats your boat i guess, i just think its important to note that ESS doesnt put as much boost as other tuners and have had no failures (to my knowledge at least).

Where's the "duh" smilie? Just part of the game, and part of what makes modifying and/or racing cars so much fun. Most people don't have the chutzpah to mess with a car because of this phenomenon. The risks of modifying a car are very real, it's just a fact of life and I've seen too many world-class tuners blow stuff up to let anybody tell me different. Sometimes stuff breaks when it makes more power, unexpected failures happen, what once was strong enough becomes a weak link. That's why it's such a small club and it's just part of what makes it exciting.

sorry to hear the news - that really sucks. props to you for being candid and keeping the community in the loop regarding the root cause here! and of course, props to Gintani for standing behind their products.

hope you get back on the road soon.

To the OP, sorry to hear about your situation -- hopefully a teardown pinpoints the cause and people can learn something from it. Props to Gintani for stepping up to the plate.

Yo if Gintani really is covering the cost of all repairs that is sick. That is waaaaaay beyond what they need to do. I mean what aftermarket tuner company would warranty the motor? Without even taking into consideration your claim of oil starvation and running higher than normal boost. But I have to agree...the S65 has a high CR and it's a little suspect to me some of these boost numbers on the higher HP kits.

Yes, when you take just one line of what I say it sounds a little over the top obvious. But it does seem like quite a few blown motors from S/C. Haven't heard of one other mod on this forum causing a blown motor. My point from the beginning is that it's starting to sound a little more and more probable that this engine isn't a great choice to start boosting with it's already high compression.

One more vote that's insane to boost the S65 engine, especially to 9 and 11 psi when the bearings are known to be marginal already. Good luck man.

G-Power blew their motors with a bad tune ...

ESS can but will not unless you lower the compression ... Yeah they're not really into running meth.

Other then G-Powers bad tune blow up this may just be a case of "Bad Rod Bearing"

The S65 if run on proper boost levels is a good motor to boost. I think ESS has proven with a high volume of kits sold without any failures it is really about making sure you keep keep boost levels and tuning within reason. I think Drew would agree as he found out that anytime you make the decision to push the limits as he did you run a much higher risk of failure. High boost on this motor can lead to detonation which will take out rod bearings.

Thanks for sharing your story with everyone Drew as it will hopefully open some eyes to what the limits of this motor are and the risk involved if you decide to push them. Hopefully your car is back on the road again soon.
