Most power made on a standerd ko4

Nice.  Any change in hardware?  You were at 340ish before?

No hardware changes. Just different boost pressure and fuel injection (much more of both). The real IAT in that bench were around 50ºC. It's not the best vented one but the results at the wheels are identical with the old one.

I was at 346 CV without octane booster and 355 CV with octane booster.

Haha I know it's been 'measured' on that particular dyno a few times, but if you revert back to science for a minute......to make a genuine 400hp, you need around 45lb/min mass flow rate through the engine - airbox inlet to tailpipe. 

You keep saying lets revert back to science and maths, as if you are offering irrefutable calculation and maths when in reality I think you are offering crude and basic maths and presenting it as proof. Im an engineer, so I don’t omit calculation for fun. I may be wrong, but I would have thought the amount of specifics involved with calculating the difference of 50bhp, would be mind boggling (?) If the calcluation really is that simple, and an accurate maximum, minimum, whatever, can be obtained fairly simply from calcuation based purely on the few physical attributes we have, I take it all back and will concede 400bhp is impossbile from a k04 turbo 

Its for this reason I keep going with testing over calulcation. If you can’t calculate it easily, test it. Which is obviously where the debate lies, the accuracy of testing.

Well as you are the engineer, why don't you prove 400hp *is* possible then, ffs.

I've not once said I am the all seeing overlord and stated everything as fact.  You are just coming out with ridiculous statements like that because you can't come up with a counter argument.  I also said I'm basing my opinions on experience and science, the science of engines being able to make a certain amount of power for a given air and fuel input.  I don't believe a standard KO4 configuration is capable of 400hp measured on a bench tester to DIN calibration.  Prove me wrong.

And yes, the accuracy of testing.  Rolling roads are riddled with inaccuracies, that much we all know.   What other rolling roads have seen 400hp from a stock KO4 engine?

I 100% knew this was coming 

Clearly stating that proving, or disproving (it really doesnt matter) based purely on calculation is NOT feasible (for me and you). Hence the need for testing...

Seems like its just going to disolve into insult and a personal based arguement, im out.

..... seems to me you both need to stop flirting and get a room 

[Pesky jones]

i'm just trying to win his approval. Is this not how flirting works?

Well I think that’s how it works ..... I generally just drug them , saves on time

I'm just more interested in whether a genuine 400hp is possible or not, from a KO4 engine with the usual bolt ons.   It would be nice if it could do it, but I don't think the turbo is anywhere near big enough for it. 

I agree and believe the 350 bhp number is more realistic for a K04...guys over here work very hard at getting to 375/380 bhp (330 to 340 whp) with a K04; adding W/M injection and running E85 in order to accomplish even getting close to 400 bhp with a K04. And yes...even with the TTE420 and BW EFR 6758; people are lucky seeing 400 to 420 bhp (355 to 370 whp).

Here's what APR's Arin had to say: "Careful comparing US to European figures. Most all European tuners claim crank figures which are calculated using dyno coast down procedures. In some cases we'll see over a 100hp increase using this method, which is insane and inaccurate, thus not comparable to what people measure here in the states." ...on discussion of the same topic of 400 bhp with a K04. http://www.golfmkv.com/forums/showthread.php?t=121909

I'm happy with 299 WHP and tested in 5th gear the bench measures almost 100 HP of drag. It's less if tested in 4th gear but my wheels kept spinning in the rolls. I need the LSD fitted, I guess...

LSD  ...you and me both 

[Bodyboarder81]

I have one of this lsd things fitted and even with my modest 315bhp it struggles in anything less that nice dry weather
