True, but usually a k03s is on its rear end by 6500 rpm so a gear change is needed.  I have a raised limiter on my map, but most pointless thing ever.  If I can pull hard to 7250rpm on a stock head and 7500rpm on a uprated one, thats a bit quicker Tongue

A K04 will not pull "hard" to 7250 I'm afraid.

this ones off a 2011 golf R, from the plots ive seen, they are holding near enough 21psi to redline.   I know itll start to feel less 'pull' as revs increase, but itll be a touch better than this k03s lol

Pretty happy with the power.   Bit more timing and hopefully should get some more torque on it.

Getting there slowly with it now Smiley

Any thoughts?  Would be nice for a bit more lower down torque, which I should get by timing lower down?  Would making it a bit richer in them areas make more torque too?

Got my methanol kit wired in yesterday, managed to get a log today in the dry.   Now got a big overboost which has be about 10mbar from the limits of the map sensor.    Ive got a log with meth on and meth off.

WGDC% is far less with the meth on.   Seeing about a 40mbar difference in boost pressure desired across the whole revs.  Got me stumped Sad

Hi guys

Bit update.

Still getting a huge overboost, which looks like its over 22.5psi so map sensor plays hell, engine starts to misfire and everything starts screaming at me and flashing.

Ive no idea how I can stop my boost pressure from keeping boosting, yet the specified boost is well below the actual.

Id have thought that the boost profile will follow that of the desired, but mine doesnt Sad

im fairly certain its all ok,  its a upgraded piece of silicone.

Maybe my N75 is on its last legs?

Just checked: WG pipe is fine.  no leaks.



Which line is it meant to follow on pictures?   Guess its the load one?  Is my specified load too high?

Well this isnt right.

N75 plugged in and unplugged get the exact same graph (near enough)

Somethings broken somewhere Sad

Check the line to your wastegate. It's probably been swiss cheesed.

Fixed.

Just a bit tweak to make on the area around 3-4000rpm where boost holds then increases and sort the intervention out at 6250rpm where engine load gets too high and throttle gets cut.

But looks a lot better now.

New log with a tweaked LDRXN.

If I could sort that actual boost over desired out, it would be spot on.   But I guess 21-22psi isnt too bad for a k03s.

Just to wrap it all up as cars now off the road waiting to have its engine out and new goodies added....burst coolant pipe rubbing off top of gear linkages finalised its fate in coming off the road.

Anyhow.....good power today.  Got the torque back I was 'missing'...got this back by timing added to the bottom end.  And top end nice gains off the water meth.







Might even have a go mapping the TSFI turbo in too with those results.
