Broken it :-(

Drags today, first run, sh*t burn out, staged, boost to about 5psi, wheelspin, think I hit the limiter, hooked up and went .
Could
see some smoke from the exhaust, kept into it and went 12.8@117. Got to
the end of the run off and car felt sick, some banging from under the
car, thought I'd bent the tailshaft or something.
Anyway the banging stopped as soon as it started and I drove carefully back to the pits.
Still
some blue smoke out of the exhaust, popped the bonnet and loud dack,
dack, dack from the engine and some steam from under the turbo heat
shield.
Had the car trailered home.
Oil pressure is still good and the oil looks clean.
Waiting for it to cool down before looking at the coolant.
Possibly a head gasket might explain the steam but the dack, dack is concerning.
Dack is a louder, deeper tick, if you know what I mean.
Wife is not happy.

maybe a piston me hope not

Shit mate, that's not good...........It does as Rad say's sounds like a piston.

Almost certainly a bent rod.
At least it didn't come out of the block.

Still ain't going to be cheap to fix mate. Are they still factory rods and pistons mate??

Yeah they are.
My guess at cost would be $15k.

that'll please the other half i'm sure

rad. after looking at your picture im not sure which half your talking about

15k??.

I hope You have another car to drive around in, in the mean time?

A mechanic I was talking to last night said it sounds like it was leaned out too much to get the greater horse power. Talk to your last tuner. But you could be lucky and just have a blown headgasket but it depends on what 'Dack Dack' means?? I guess you have checked that out by now though.

Dyno plot looks very good, AFRs richen up as the power increases.

Will get the money sorted first, then get it looked at. Once it gets torn down I want to get it fixed, not find I haven't got enough money. Whatever the problem, will go forged internals. Probably keep the standard turbo, 'cos it's fast enough on the road, but add a NOS system for the track.
Not my daily driver, thank the lord.

has the rebuild started in da quest for more power

Went into Torque Performance last week.
They should have started on it today.
But who knows, at least it's in the shop now.

cool

Update.
Leaned out in No5 cylinder, big loss of compression and spark plug munted.
Engine coming out for further assessment.

Oh good to know my mechanic knows something after all. Might let him change the oil in my car now.

Don't get too carried away, changing the oil is a big job.

Don't forget to get a fixed price quote

My electrican.. (lol) changes my oil.... Price is fixed, for sure

same as mine ,except it was number 3 cyl

Different tuner! Same result. Well almost.
Oh well, will just build it stronger.
How much is yours running now?

still running the same kws but have a lot more torque

Hey Steve,do your torquing up at Meremere i want to see how it goes...pleeeeease

dont drag it any more. wast of time since it is a stick shift .i just put it on the track now. enjoy it a lot more.

Steve's right.
Drag a manual turbo six is no joy.
Track days are where the manual excels.
You'll have to make do with mine. If my wife lets me :-(
