A couple of weeks ago I blew the engine on my evo... thought I'd share the pain.

Stock engine, stock boost, only power mods being 3" turbo back exhaust.
Mainted religously, just had 45,000 mile service.

Went bang doing 80mph... between 5-5,500rpm








Time for a for new forged engine.

 

ouch gl with the new build

 

Damn that sucks have fun with the build

 

Kins.....Something was critically off for that type of damage to occur....I am no "Guru" & curious as to the root cause......Fill us in w/ what you know

Peace

 

**** happens. What gear where you in to be doing in excess of 5k rpm at 80? Shouldn't have happened non the less though, sorry for your misfortune.

 

Wow! Why would the engine blow under nomal driving? Upside is your building motor.

 

ouch.... sorry to see wat happened with the car good luck with the new motor

 

dannnng sorry for the bad news but GL on the new build =D

 

damn quite the explosion..now its time to build it better.

 

What happened?

 

wow that piston is disintegrated...that engine must have been under a lot of pressure

 

Could you have possibly been accidentally running on a lower glass of fuel ? Perhaps without even knowing it?

Has your ECU ever been tuned or flashed with an upgraded ROM?

Most EVOs come from the factory with an excessive amount of timing. And most EVOs should really be tuned for the local fuel that is used regularly. Factory tune on most EVOs is not that great. Some would say it is even poor.

 

Ahhh....yikerz!

I hate seeing that! :X

Well, goodluck on your new build. The new beast will be some good stuff.

 

That sucks to hear.
Have fun with the new build.
Keep us posted on the project.

 

Thanks For further details see my original thread on MLR here:

Yep... life is a ***** at times

My tuner - Mathew Goode AKA Madmat on MLR thinks the damage is down to the rod bolts failing. We have yet to strip the engine down to try and find the cause. It's catastrophic engine failure so not much point crying over spilt milk now.


I must have been in 4th... I think... the RS box has short ratios... but I think 4th would make sense.

I'm not sure if it is normal driving.... I was having driver training at Milbrook proving ground... cadence braking from high speed. I did a few runs... a standstill start accelerating hard to a given speed (80 then 90 then 100 then 110 and finally 120mph)... once at the given speed I had to stamp on the brake pedal and cadence brake to a holt.
The engine blew on my final run when I was accelerating to 120.... to be honest I'm not sure if I was in 3rd or 4th... I forget what speed I would be doing in 3rd or 4th at 5,000 rpm....

You're right... at least I get to drop a forged motor in, upgrade the tubby and whack up ze boooooost

Thanks

Thanks man.

Bigger and better my friend

See above

I think it was the rod coming loose... that smashed the piston into the head and pushed the rods out of the block... I have 2 holes in the block.. (2 and 3)... I'm quite proud of that

I don't think so Jim... had at least 1/4 of a tank in there.
Ecu is as it left the factory.
Stock boost on the 5 RS is 0.9 bar... the 3" turbo back and decat can sometimes cause the car to run up to 1.1 bar. The car has never been tuned.... ideally after fitting the exhaust and panel filter the car could have done with a remap, A/F ratio knock count etc checked. I was about to have a walbro 255, hks 272 cams fitted with a remap but then this happened.

Oh well.

Me too it aint pretty.

I will keep you posted
