Ca's dont like 2 bar boost. Please read.

Greetings guys.

Well got the boost up to 1.4 bar on Friday and it pulled like a MOFO!
Saturday I was chasing an M6 when all of the sudden all hell broke loos... Car boosted like there was no tomorrow and my boost gauge went off the scale.( which is 2 bar ) ๐Ÿ˜ฎ Car died, What felt like pepper-spray came threw the vents and I nearly rolled the car since I could not see/breath. Eventually I parked it to pick it up the next morning... since I was kinda drunk.
Get there the next morning to find that I could not see anything wrong with the motor? No obvious signs... no oil leaks nada... The motor still starts but with a fair amount of smoke coming out of the exhaust... Have not opened it up yet... Any idea's what it is that broke? I am thinking rings.

Cheers.
Alex.

its anybody's guess what what got destroyed, but ya, prolly rings and/or pistons, head gasket, possibly turbo ect.

So the stuttering didn't tell you you are fucking something up?

Meaning of Stutter of normal people:

1. to speak (a word, phrase, etc.) with recurring repetition of consonants, esp initial ones
2. to make (an abrupt sound) repeatedly the gun stuttered
n
1. the act or habit of stuttering
2. a stuttering sound
[related to Middle Low German stรถtern, Old High German stลzan to push against, Latin tundere to beat]

Idiots dictionary:stuttering

1:20 beers and a cop pulls you over
2:Detonation:the premature spontaneous burning of a fuelโ€“air mixture in an internal-combustion engine due to the high temperature of air compressed in a cylinder.

oh well everyone need to pay their school fees sometime with a CA...

no cars like 2bar of boost.... my previous S15 with HKS 2,2L only boost 1,9bar @ the drags... like 5 times

HH8rlequinb31 Jan 2011, 13:14

Hey guys.

Thanks for the responses... Yeap I guess these are my school fee's... Well I aint no mechanic and go by what people tell me. I was told the car should run fine like that... I thought the stutters were the low octane petrol that we get here... i did not know it could cause damage. O well... Was under no elision that the engine was going to last forever... at least in the 5 driving sessions that it did last it pulled like a freight train. On sale one CA18... Wanted RB25 ๐Ÿ™‚

Is it 2 bar you read from this gauge?

Asking because 20psi is about 1.4bar, and it is still to much!
Unless you pull timing so far that it would make more power with lower boost anyways.

The stutter or as it should be called splutter is normally caused by low fuel pressure....so make sure everything is good before you hurt another engine...

Haha, yeah there is a SX, mobnes in Switzerland I think, that is running 2.35 bar... That was when he made 577HP, he does now close to 750hp... ๐Ÿ˜€ ๐Ÿ˜€ ๐Ÿ˜€

Shall I just change the Title to MY Ca does not like 2 bar boost ๐Ÿ™‚ Stripping for spares if anyone interested.

HH8rlequinb11 Feb 2011, 08:39

I have a bit of a delema.... Going wild on the CA or just going for a RB...
Thing is I don't know if my pockets are deep enough to go wild on the CA.

Thoughts?

It's gonna cost you less than an RB swap...

HH8rlequinb11 Feb 2011, 08:50

Great!!! Ok CA it is then.... Think it will be cheaper as well since the exhaust manifold and shit has already been made up... Will start stripping this weekend as soon as I am done with my Mini.

Thanks!
