I forgot about yours. You guys were running only on port injectors with an AEM EMS at the time if memory serves me correctly.

Would like to know more info on @alexisfire02 engine failure with the larger supercharger. Like who tuned it, psi it was running, etc. Must have obviously been a tester since the 335 is not public yet.

This should answer most of your questions:

I actually read that already. But just seemed like a little beating around the bush of what happened, lol.

Probably can't say much about it, but still would love to know.

You can add @civicdrivr to the list. Vortech, blew up while on the dyno.

Didn't @Frs300 over boost ?

How would he know with no way to monitor boost pressure?

I 100% agree. The only way to know that your tune is working is to be able to monitor it while driving with the use of a boost gauge and a wideband.

I even researched his, but I couldn't remember if it was forced induction at the time. I just remembered his losing coolant thread and post in @nelsmar 's FA20Club thread.

No idea. The logs from the run showed zero detonation, AFR was dead on (factory O2, so there's that...), there was no knocking, and it did not overboost (IIRC, the logs showed 9.4psi). I must also mention that I kept the stock rev limit as I saw no need to rev higher.

I have some pics of the carnage that I can post when I'm not on the work laptop. But yea, that was my experience with this motor.

Also, not that this matters anymore, but Visconti picked up the tab of the motor and the labor, and drove me 4hrs back home that night (then turned around and drove all the way back to CT), so lets not use my experience to disparage him - there are plenty of others that can easily accomplish that.

Thanks for posting the details.

Yes, the motor blew with about 33k on it. And yes, it did have coolant issues in the past, which I thought were behind me. I guess I'll post the story:

I noticed the car losing coolant since new. Around 19k miles, I noticed that the coolant loss accelerated and I had white/light gray smoke from the exhaust above ~4k miles. Queue dealer trip #1. They did a compression test and scoped the cylinders. The #3 cylinder was down compared to the others, but not "enough". There was coolant residue visible in the cylinder as well. Toyota requested that I monitor the coolant levels.

Dealer trip #2: About 3k miles later it was low again. They topped it off and told me to keep looking at it.

Dealer trip #3: At ~26k miles, while on the highway, the car started knocking and misfiring. I brought it to Toyota and they said that the valves on the #3 cylinder were bent (none of the others though) and the paperwork said "something in the valvetrain came apart". They replaced the cylinder head and sent me on my way.

From then on, the car ran fine. I still noticed some coolant loss, but chalked it up to evaporation. At 33k miles, that's when the fun stuff happened.

I had installed a wastegated Vortech kit along with a new fuel pump and injectors and had it on the dyno for live tuning by Visconti. We had the standard 9psi pulley on for initial tuning. At 5psi, it made ~250ish whp. At 9psi, it was consistently making 280-285whp. Earlier that day, prior to putting the kit on, the car put down 171whp, in line with other mostly stock twins that have run on that dyno.

On the 9th run, it put down 286/216 at the wheels. Then the oil volcano happened. The rod snapped about an inch below the wrist pin, spun around and punched a t shaped hole in the block. The cause? No idea. The logs from the run showed zero detonation, AFR was dead on (factory O2, so there's that...), there was no knocking, and it did not overboost (IIRC, the logs showed 9.4psi).

Rod fatigue methinks, unsure how it occurred though.

@civicdrivr what weight oil ?

Not sure if it's the same with the BRZ or not, and some of this is just superstition IMHO, but Subaru engines seem to hate Mobil 1. Most Subaru guys avoid it like the plague, even with no definitive scientific basis. :D

Well there is some science to it, their 5W-30 is not very good and breaks down easily. Being the recommended weight for the WRX/STi, it's not recommended. Their other weights like 0W-40 are actually decent.

looks identical to my motor...same exact spot.

So I guess I decided to compile the list today:

@Frs300 - Full Blown Turbo - blew his in 100 miles, reason unknown
@nelsmar - Vortech Supercharger - blew his after 12,000 miles due to running lean
@alexisfire02 - Larger Sprintex Supercharger - blew it on the drive home from getting it tuned
@Innovate Motorsports - Innovate Supercharger - blew it while developing the OTS tune to sell with the kit
@Jesse@JDLAutodesign - JDL Turbo Kit - blew up do to overboost while running AEM EMS on only port injectors
@civicdrivr - Vortech Supercharger - blew up while on the dyno
@shiro - Greddy Turbo - blew his in less than 600 miles believe to be caused by the cam timing

If anyone knows of any others, please post them up.
