She doesn't need to know. Just tell her you are getting it prepped for the track.
I told her this morning as we need to borrow her mums car if possible.

Mate my day is busy enough as it is without having to worry about this ***** and get all the grief from the gf for spending more money on my car after just forking out on the map
you are chasing getting the MAX out of a k04
by definition..... something running at its max is going to be more stressed, as are components around it, than something bigger but working less hard
hoping for you its just a gasket of course.. as the jobs going to be a right pia..
good luck fella

Cheers Bill.
Thing is I'm not wringing the turbos neck as its only running 21psi. Some guys are running 25+ on their K04s.
Bottom line is I have a cheape flimsy mani which is renowned for cracking and I've run it for 6 months without a turbo support bracket.
Cheers Bill.

My thoughts exactly.
I hope the manifold isn't cracked for your sake, would be ****** annoying. I have my fingers crossed that you'll be pleasantly surprised and find it's the turbo to manifold gasket has blown through.

dude you are ringing its neck... forget peak spike boost numbers... its producing the max power it can.. which is flat out.. No more left in it, wg nailed shut etc the power delivery is late... for a k04, and because niki has been trying to manage temps... low end boost spike kicks low end torque bu cyl temps are too hot to sustain power at top end @ same time. You cant have your cake and eat it, and he's gone for less is more in boost terms, max'd the ign opportunitys whilst its lower boost at the lower rpms, and got it to hold as long as possible up the revs to hold torque higher in the rev range, hence crack the 300bhp.... but its flat out.. We have all been reading the fb posts...
Dont get fixated on peak boost. Sustained boost at higher rpm = flat out and all that could be got, was got by niki.. I'm sure of it.
v1 relentless... not exactly the best, and v3 is superior fo sho... but my comment stands. your whole mission posted across the forums is to get the max from the k04... Expect some side effects of this..
no support bracket? really? omition or by choice?
fit it on v3 dude
Would you say that your B5 TIP creates more power whist putting the turbo under less strain?
Not looking for a fight, genuine interest on your opinion of flow vs power vs reliability. Reason I ask is you just said "something running at its max is going to be more stressed, as are components around it, than something bigger but working less hard"
But I'm not sure if you mean a bigger turbo, or the components in general. Because by all accounts the turbo isn't running at it's maximum, so I'm presuming you mean the surrounding components in their entirety? But Westy has your own B5 TIP, he has a Relentless manifold, he has WMI, a beefy FMIC and I'm pretty sure he has rods doesn't he? What else can there be that isn't up to 300bhp?
From what I can gather, the reason Westy/all the other high power K04 setups that are coming out of Niki's are making the power they do is due to the flow and boost characteristics. Surely 21PSI from a K04 is well within it's safe operating parameters? I've always presumed it would be exerting the same strains on the components as a GT28 (for instance) at 16PSI making the same power?

you're missing the point totally jardo.....
21psi is a peak figure.
it's what it's holding top end that's pushing it hard.
Peaking 21psi isn't high no, but trying to hold it flat out at 6k+ rpm is.
I have no question that Niki's mapping is brilliant and he's extracted some serious power from westys car, but lets not kid ourselves that is isn't the absolute limit of what it can produce.
Just because it's not producing the highest peak boost figures doesn't mean it isn't flat out.
Boost is limited low down to reduce heat and stop the WG being blown open by a big spike.
At the top end the WG will be nailled shut and the little ko4 will be giving everything it possibly can. There's no other way to get 300bhp+ numbers from a stock k04-023
Would you say that your B5 TIP creates more power whist putting the turbo under less strain? That's something I've never quite understood but presumed as the case.

i would have thought that with a B5 TIP the turbo would be doing less work for the same boost request putting less strain on the turbo because of reduced frictional losses through the larger gauge TIP
k04 is not rated to these levels.. its "just" got over 300bhp, which is an achievement no doubt but there's nothing left in it... It was sub 300bhp and max'd, and cooler damp day helped it break the barrier. This is max'd.
I do mean bigger turbo working less hard.
temperatures is whats kills power and components....... V1 mani does'nt have a reputation to be proud of, so its rapid failure (remember prawns) should be a surprise to anyone.. Also mapped "safe" but the temps on the manifold under duress caused it failure. (and its poor quality)
Yes my B5 TIP has added more power without any more strain... Its made it more "efficient flow", so less losses..
turbos blow well, they are crap suckers
I have already said why the power is where it is and doing what it is... as has niki on his fb posts..
you cannot drive high early boost and expect it to hold power @ top end..
TEMPS will not allow this
out of interest Bill, do you know the Ar of the ko4 turbine housing?
Is it comparable in terms of numbers to the garrets ie 0.63 or 0.86? or is on a different scale somehow?

you should be in the garage right now!
Throw the beer on the manifold...
