Most power made on a standerd ko4

[harveym3]

Hi all I'm doing a ko4 conversion and was wondering what is the highest power and torque made on a standerd ko4 turbo ??

[r5gtt]

400 + 420ft lb but not every tfsi can achieve this safely. Ask AKS or R Tech

..... and all depends on what dyno being used . They can vary quite a bit .

Im currently half way through. 2008 BWA DSG, 2+ hardware. Im on a base map at the moment from R-tech, will be going back for the full custom mapping once other little niggles have been sorted. Ill be hoping for 350 / 350 ftlb. Nikki has tuned BWA engines to over 400 hp/ftlb - but it really is a ticking time bomb. Torque should be capped as that is what kills the rods NOT the peak hp figure.

This.

400hp with some creative coast down calculations, or 350hp measured properly on an industry standard bench tester.

The trouble is, people who have spent £1000s on hardware and software can't handle the truth.  And software sellers don't want to tell you the truth either     Even OEMs do it.  They quote PS because it's a much bigger number than KW.

Hitting 400 bhp imho isn't a safe way to play it if you're looking for numbers as in the end you'll probably end up with a rod popping up to say ello mate how's you been, long time no see  or you'll have a massive power band and lots of fun for years to come, either way I would be worried about it everyday

...Unless a good, tfsi knowledgeable tuner tunes it to 400bhp. Then it will be 400bhp on the bench tester.

Thats cool I'm just asking as mine will be goings on the rollers soon and I'd like to see how well it dose . I've done a few new bits that I've not seen done so it could all go tits up

If you want maximum power you may need to replace the lpfp as a member on fb has done to achieve higher numbers

Go on...(!)

Its mainly breathing upgrade I'll let you know more when it's finished I need a 3 bar map senser  and a 200 bar fuel pressure senser but in still trying to sorce them .

Would you put a tenner on that?   I can guarantee an engine showing 400hp on a rolling road would not measure even close to that on VW's factory bench tester.

Fair play. Not going to disagree - just didnt know whether you were including claims of 400 by good tuners in the statement. So presumably your day in day out stage 2+ 350/350 (not pushed to the absolute limit) is actually nowhere near that either?

Also that statement leads to the assumption that the inaccuracy is exponential as you go up, as stock cars on the dyno make stock figures.

I like the topic and I agree with Pudding. Forge the BWA if you want to reach top numbers with a K04.
