my turbo d16 recently blew up at 10psi because one of the couplers came off at the turbo. This is because of flooding in the engine bay right?

nonvtecD

huh? What blew up? no, a rich mixture will not "blow" up your engine.

THE COUPLER PROBABLY BLEW OFF BECAUSE THE CLAMPS WERENT SECURE ENOUGH OR YOU USED SOME SILICONE BASED LUBE TO PUT THEM ON THE CHARGE PIPES. TRUST ME ITS HAPPENED TO ME BEFORE NOT BECAUSE OF FLOODING IN THE ENGINE BAY . UNLESS YOU MEANT WATER ITS POSSIBLE IT MESSED UP THE CLAMPS.

blew up meaning a hole in my block. And yeah i used home depot couplers which ive learned my lesson. Those clamps were tightened to the max and the couplers were 4 bucks a piece!....anyways i think the flooding of the engine is what blew up my motor when the coupler blew off of the turbo. Nothing else explains it.

how about this explanation:

your boost was turned up so high that it blew the coupling right off, but not before it blew a hole in your block. is that a reasonable explanation?

a flooded engine (running too rich) will not run.

could it be the FMU (if ur running one)?

i heard the coupling blow off but i didnt know it was a coupling and ignored it because my car always backfires anyways and 5 secs after it comes off im still flooring it then kaaabooom. Now wouldnt that sound like the fuel flooding the engine and since the turbo coupling came off there would be a huge lack in air compared to the amount of fuel coming out at WOT? Like using 450cc injectors tuned for boost and running it suddenly on a N/A setup at WOt.

If you're running an FMU it wouldnt be running rich because there was no boost present after you blew your coupling. If there's no boost the FMU doesn't affect anything.

if he was using an FMU, when the pipe blew off the FMU would not at any fuel pressure. Once he blew the pipe off, he's not going to be boosting any more. the fmu raises fuel pressure according to boost. so thats no it

I can believe think happened.

if your car runs too rich, it will misfire

Including what you just said.

Over rich will kill the plugs, generate a number of misfires and eventually kill the spark altogether. It won't put a hole in your block.

I wasnt using a fmu, only a safc set at -37 to -40 across the board and was boosting fine till i hit 10psi and thats when the coupler popped off and the car still at wot shot out a piston.

Tactic$

the hack killed your car dood

Drkaccrd

Yeah I use to run the hack in my car....It sucked major ballz. Blowing a hole in the block...yeah its possible., due to improper tuning and running a high boost (high boost meaning anything above 7psi without proper tuning) setting on top of that.

Evanmb44

running rich will not cause you to throw something through the block

0Synapse Motorsport

Another victim of the hack, deff not due to being rich. Sorry to hear it man.

Drkaccrd

I agree running rich would foul out sensors not cause detonation, and it would cause it to bog down with too much fuel. And not blow the engine thats for sure.

sadangryboi

ive have my pipe blow off of my turbo and nothing happened...just no boost. think ur tuning caused u too lean out too much

SOHC_MShue

Think about it man...you shouldn't have even hit a rich condition in the first place. If your coupler blows off then you aren't boosting anything and your ecu isn't even going to be reading off the portions of the maps that would be dumping in excess fuel for boost.

nonvtecD

Another victim of stupidity, your car always backfires? and you're cool with that? and you thought a rich mixture blew your motor up?

Whats wrong with backfiring?? just means im runnng a tad rich and a whole bunch of turbo people here have the same symptoms. An no im not cool with that, its just happens to be a part of the tuning up stages. But i will take the blame of being an idiot when i choose to use some cheap home depot couplers. But theres still no clear answers to my question of how my engine blew up. SAFC hack but how? advanced timing? im using a msd BTM to composate for the advance.

mamaboy

your car would stumble if you ran rich. if you blew a coupler off you have a map sensor it won't do anything, especially a coupler that's way down away from the throttle body. it'll just suck in air just like a stock car.

Evanmb44

blowing a coupler off happens to most of us boosted guys all the time. nothing happens from it. something else killed your motor, not the coupler coming off

BoostedCivicSedan

was it common for you to blow off couplers before this?

How much boost were you running?

What kind of boost controller?

What kind of wastegate?

What manifold?

Have you ever had boost spike/creep issues with your setup?

Did you tune with a wideband?

Funny I can already predict most of these answers and come up with a good assumption of what happened to your car... Seen this way too many times...

Dunc

I agree, I've blow one of my couplers off twice now but nothing happens. You just lose all boost and the car feels N/A again (thats an evil feeling I never want to experience again haha)
