16v Power. True or False?

I have read in several places on the web that the 16 valve ABF was originally produced by VW to produce 170bhp but because the VR6 was only 174bhp they changed the ecu settings so it only produced 150bhp. Does anyone know if there is any truth in this.

 

vaugely.

 

Yeah thats more or less what happened, thats why a lot of ABF owners find their cars make more than 150PS when put on dynos!

 

can a re chip regain its go?

 

You normally see them in the 170`s, Golfgirl had that in her old mk3 16v at Stealth, stock?

 

All depends on the rolling road, innit...

 

Of course.

 

Is that why the ABF has milder cams than the KR then? Or maybe it's something to do with overfuelling killing the cat with a longer period cam.

 

Thinking about it, is there any VW engine which has a reputation for
putting out less power than it's meant to? If you believe everything you
hear, a high mileage KR will put out 150bhp+, the ABF was restricted
from 175bhp so it didn't harm VR6 sales but a healthy VR will put out
190bhp+. Seems like either VW were very modest about power claims or
there are a lot of these "very healthy" engines about.

 

ABF vs KR cams are 'swings and roundabouts'

ABF cams have more lift but KR cams have more duration.

Greg -

I hired a 1600 FSI mkV last year and for a laugh put it on Stealths rollers.

VW claim 115ps
Stealth measure 127bhp

Must be a good 'un

Healthy little engines those 1.6 FSIs. VW restricted the power output so
they wouldn't harm Veyron sales...

 

it might have been an ODB2 one or one with green writing on the ignition ECU...

 

And a couple of hundred thousand miles on it to loosen it up.

 

You cynical bastards.

moi?

 

How different is the ABF to the KR in real terms? The valves are the same size arent they? Minor differences to the cam profile as GVK says, but the block and crank arent radically different are they? I've never had one to bits (yet! )

 

ABF is taller block, longer rods, larger CC

 

I really havent got it together today.... I was thinking 9A Ignore me

 

It's the same for the X-flow 2.0 8v in the mk4, they don't have the variable length inlet (like the 1.6 8v does) so that the power figures don't embarise the hi-tech n/a 1.8 20v. clever marketing

 

I've just got in a KR 16v with 195k on the clock. At that mileage it has to be close to 200hp?
Smokes a bit, mind.......
