I think your a little confused mate, it's the turbine wheel that broke up not the compressor wheel so they would of gone out the exhaust not in the engine! lol

 

Thats overspeeding her fella!

 

If you lift your foot of the gas when you hear it go bang, the vacuum sucks back into the engine.............

 

Karl cant believe i didn't see this thread earlier!! Shit news buddy, could have been worse i guess... in all honesty im surprised its lasted this long lol

Mate, if his car is sucking exhaust gasses back thorough the exhaust valve he has other problems bar his turbo.

If his compressor wheel broke up (never heard of this happening... heard of the nut falling off lol) then this could have happened.

Rob,

 

Yup, poor old thing has had a hard time! lol
There is no chance of any bits making their way from the turbo, up the manifold, past the valves and into the chambers mate.
It's not the end of the world Rob, got a stage 3 .48/55 on it's way hopefully end of next week so lets see what I can squeeze out of that shall we!

 

Good work my man! break her properly!

 

lol

 

Good news! can't wait to see how well it does, btw your base map is still in full use, just passed emissions at the MOT with flying colours tunerstudio's VE analyse live is also well worth it.

Rob,

 

Ah sweet! I've never used it but will be making a fresh map when the stage 3 goes on so i'll give it a look mate.

 

So far i've done 10 miles and the off boost section of my map is pretty good, starting off with your base, adjusting it for my injectors etc then running VE analyse. It really pays off when you've made a small timing change for example. After a good read on the MS forums it seems to do the fine tuning stuff much better the an ooman.

Rob,

 

The AVC-R sounds a good controller karlos, esp to hold them boost levels at high rpm's!

Will be interested to see the new turbo/map and what it produces! Good luck with it m8!

 

oh dear! glad to see it getting abused though- will be interesting to see wot you can squeeze out of a 3 now!

 

Are you gonna run a dump valve with the new turbo Karlos

 

What?? Pmsl

 

lol i thought the same

 

No mate I'm not, as the damage was done by overspeeding the turbine as Jimbo said....
I have thought about it but I hate the sound of a dump valve and love the sound of a stalling compressor wheel! lol
There was no in and out play in the shaft only side to side which I'm hoping was caused by running out of balance after losing bits of turbine wheel... If it was caused by not running a DV then that would be a pain... But there's only one way to find out!
Yeah classic post! lol

 

Bloody hell you raped that turbo! Love it!

 

i done that one night in my s2 with the 2.1zvh and a t34 was givin it beans and all i heard was tink tink then no power and shit loads of smoke out the arse of it so put a stage 3 t3 onit and it was alot quicker and less lag.

 

bad news karlos. sounds like it had a hard life though. be good to see how the stage 3 fairs. are you on low comp or standard?

 

Slightly higher than standard CR mate.

 

interesting, skimmed head and standard pistons? mine apparently low comp, although i`m not certain as i`ve just read a few threads about where i got my engine from. lets just say it wasn`t good

 

Oh! Bad news mate!

Stock CR pistons with the head simmed twice and the block decked once too.
