    K04 K16 clipped/clearanced,7+7, BBT hybrid on a stroker...., largeport head, 80% meth wmi, forge fmic, LCR, B5 induction.... max'd 550cc injectors

    Unplanned boost... N75 crapped out, but timing pull was ok, and I was keepign beady eye on very high egt's...

    Well and truely setting a power/torque figure from a k04 framed turbo beyond my imagination..
    Not safe.. dont try this at home, but intriguiing outcome none the less. Poor v3 mani on it glowed like the sun +++
    Horrendous flow restriction, and suicidal egt's .... but damn.. Was never expecting to see this outcome.. K04 FFS.. a one off spec but still a K04..

    Damn!

    Just to clarify... This was not a planned outcome, but a result of an N75 malfunctioning so turbo was flat out... but the results were very unexpected..

    the car in question left with 320bhp/300lbft as the egt's would soar to daft levels after 5k such was the flow limit pushing into the v3..

    during that dyno pull I was looking at Cf which were remarkably ok and egt's which I lifted early as they went into ludicrous levels... only then noticing the dyno plot and data showing what it had been up to... feck me moment.. how much boost? I had'nt touched boost from its 20psi level before, but n75 crapping out had other ideas.

    The big question now for me is add my high flow big bore manifold to this setup, rebore its hotside to match my larger collector, and then truely see what it flows like with egt's which are pseudo sensible... like our lupos 372bhp on smallport from 1.4bar boost amd egt max of 855'c

    Makes you think..

    Stroker ftw tho... lol

    I want one in lupo now... Wonder if MrsB would notice.. Hmmmm

    29.5psi at 6500rpm against a large port 2.0 engine is some serious amount of air being moved!

    Pretty nuts Bill. Not seen much make 400lbft on your dyno, let alone a bloody ko4!

    Shame it's not useable or safe, but a bloody interesting finding none the less! Must have been some shock!

    I hope you already have the mani, as TSR have stopped producing them

    yep.. a lot of air.. did'nt think it would have had it in it.. especially whilst blowing thru a small collector..
    stroker and largeport.. Hmmmm 80% meth wmi

    372bhp on the table from lupo from a lot less boost but its smallport was hurting it..

    this one, less timing, more boost it punched thru and onward.

    staggered.. it did it.

    yeah i agree will be interesting to see how mine fairs.... iv got the old narrow band setup
    but converting it to BAM i got the entire loom unfortunately my hybrid is K04-22 but is a
    brand new unit so will be putting the EGT probe in the downpipe Dan is mapping mine..
    the runners on my tsr looking quite a bit longer then the v3 so wether this will have any
    bearing on slightly lower egts i dont know.... we will see

    The car in question will get a badger5 mani and ported hotside to suit and we will see what can safely be produced..
    I am confident the record 372bhp will be pushed higher again.
