Blown engine theory

[Fletch]

Do the MPS3's have the same engine specs as the MPS6?

If so I'm assuming 6's are having similar issues with engines going boom?

I think I'll just sell my standback and avoid a dyno I don't want to risk it...

If u have a standback dont tune it to the max. I have stock engine at the moment running 210kw atw. Tuned with cpe flash and standback but its been tune to run smoother not max power ( mps garage hit 240kw on one run but pulled it back to 210kw ) Cars go boom ( most) from boost spikes, and people tuning to run big power. keep ur standback go to a good tuner run standard boost and have them tune to run smoother u will still get a power increase from standard.

Hi Luke, A hydraulicked engine will quickly bend a rod too, as will a bad case of over-advanced ignition.

[luke 3mps]

Yes. but this is part of the tuning ( the later). they do this for more power but run the risk of BOOM, safe tune will lessen this

Well in my expert opinion, these engines are running on the wrong fuel

Scotch is where it's at these days

Do the MPS3's have the same engine specs as the MPS6?

If my recollection is correct, the MPS6 runs 9.7:1 compression, MPS3 9.5:1
I specifically recall asking with interest and watching the specs when they were released and I'm sure the MPS6 has higher compression.
I remember when asking about comparitive outputs between 6 and 3 - "drop the compression and up the boost, eh?"

NEXUS, that's the recipe. It's common to significantly reduce compressions to increase cylinder volume and thereby accommodate more A/F mix. We used to use thicker head gaskets when supercharging.

Ok so does this mean due to the higher compression the 6's are more likely to go "boom" than the 3's when modded or when running on the dyno etc??

Interesting, thanks Doug.

1 more question that should be asked of all the blow ups, have they been on a dyno?

Everyones beloved dyno can put some serious stress onto a motor that isn't produced under normal day to day circumstances.
May or may not be related, but it's a question worth asking.

Also, I've asked before, any CX7's or gen 2 mps 3's having issues yet?

I think the dyno blow up figures would be bias... That's where they are tuned lol.
