Thats my boy. Just like the wind. Here one second and gone the next

I'm hoping that water methanol and a shed load of timing will make the difference.
Is WMI cars something you seen much of on your rollers? Be interesting to see what the gains are from it. Maybe something for Prawn to consider in the future too
Keep It Simple, Stupid
Ahhh now I feel really stupid
only perhaps if we try to go above 330, which we won't be doing
.
remember 300bhp in mine is the same power: weight as 400 in yours
but you destroy eveything dane
I would have to disagree
K04 cars should run wmi as std... they just run so so hot normally..

I was only gaining a little bit so believe this!
I don't think that WMI is a particularly good day to day option, I destroyed tanks with not over the top nice fun drives and then when your driving around normally your constantly trying to not make the little green led come on. For full banzai-highest-state-of-tune for overtaking Porsches on the ring then yeah but have it switchable to that mode IMO.
In my view, its a bodge.
If they run hot, then you should be looking to fix the reasons WHY they're running hot rather than putting a sticking plaster over it!
I wouldnt want to use it on a daily driver, and i certainly wouldnt be mapping in timing for it, as thats just asking for melted pistons when it stops working.
Dane, how did you used to use so much Meth? I top my tank up every week or so and I drive like a **** everywhere! lol

Welly: I dont really know mate, smaller tank perhaps so the tank empties quicker making it appear I used to use more?

Danes car is so stupidly quick it makes the world go backwards! haha.
Be interesting to see what you think of mine heat wise Bill, in it's low state of tune, at AMD on sunday, even after 6 back to back power runs, the manifold runners wern't even glowing, only the last 2'' of the collector started to glow a dull orange. I'm sure the turbo itself was glowing, but the manifold wasn't anything like Wellys 340bhp setup because it's just not being pushed hard at all in it's current form.
If it came down to having 325bhp without WMI or 345 bhp with WMI, I'd suffer the 20bhp loss and not run it I think, just seems like hassle and something else to keep on top of.
Can't wait for Sunday to see what she makes at Badger5, Just JKM left to try and I'll have had it on dynos north south east and west!
Who says its being mapped for it?
Assumptions...
WMI keeps it happy and consistent.
You can wire in fail safes if running it out was a concern.
Its benefits are well proven.
Its not a bodge as you call it.
Well i am scottish arent i?
Anyways, advocating spending MORE money on a proper turbo is hardly tight is it?
I suspect the big issue is that to spend eleventy billion quid on a hybrid turbo upgrade and only end up with a nice safe 310hp would leave a lot of people annoyed. So instead of realising that and buying the correct larger turbo in the first place like a GT2871 or whatever, they instead press on with fitting the wrong turbo and turn all the knobs up to 11 to try and get a power figure that justifies the money spend.
In all seriousness, wouldnt you rather see a customer install a nice 2871 or 3071 and get a safe, solid 350hp, that will be endlessly reliable, than install a K04 hybird, eeking out 342hp with 4 figure EGT's and needing water meth to keep it cool?
One way is 350hp done right, one isnt!
true Kev true, although I don't think the absolute safe limit for the hybrid has been reached yet. Wellys needed WMI at 338bhp, although Niki took mine to 329bhp on his dyno, and I got the impression from him that the turbo still had lots more to give and wasn't being pushed hard. that figure was made at around 18psi top end, with a 7100rpm rev limit.
Bill proved with Wellys that the turbo could hold 22psi beyond 7500rpm, so I think there's scope for 340bhp without massive EGT's. Whether the turbo could do more than 340 I don't know, but above that I'll admit WMI would probably be needed.
But that 10hp between 330 and 340 becomes more and more difficult to achieve as the exhaust restriction due to the turbine housing increases, and eventually you'll get to the point where you can add boost and dont actually get any more power.
I'm sure the compressor is capable of more, but i dont think the turbine side is. A simple comparison of the turbine housings on even a GT28RS to the K04 shows how restrictive it is!
Just as well I won't want any more than 330 then I guess! I do see where you're coming from though, there has to come a point where it can't flow any more. I think on a built engine, 320-325bhp and some aggressive timing will give us more power than we will ever need
Well some cars are mapped for it, some arent. There was mention above of mapping the timing in or using unisettings to add it, hence my statement.And ofcourse you can add failsafes for some faults like running out of fluid, but there are also faults you cant always detect, like pump failure or a leak or blocked nozzle. Or even a faulty check valve emptying the contents of the system into the intake tract when the engines off...However, a correctly sized turbocharger for the power goals with a good intercooling system simply wont need it. Its only when your pushing things to the ragged edge, as per a K04 hybrid running 340hp, or a K04 making 285hp, does it start becoming required because everythings so far outside its comfort zone.As such i view it as a bodge. The correct solution would be to install a turbocharger thats actually capable of making the desired power without being on the absolute ragged edge. Prawns example of his hybrid making 300hp is a perfect example of this. If you want 340hp, its far better in my mind to install a turbo that can happily and efficiently produce 340hp, while at the same time producing acceptable EGTs and not requring WM to be added to keep it safe.
Studs are on the to-buy list Bill! and will be sourced through yourself I do believe
word of warning, make sure you start all the bolts by hand before whizzing them up with that. My brother was in the habit of putting the loose wheel bolt into the end of the gun and whizzing it in, then going "dakdakdakdakdak" and calling that tight, until he went to fit his winters this year and noticed one of the bolts more or less fell out.
Looks like he'd cross threaded it and ripped all the threads off the bolt and it was more or less just sitting there with nothing more than friction. Luckily the hub itself was ok!
