Adjusting the actuator for more boost on an LCR?

[paul-murphys]

when fitting a forge actuator is there any basic setting i can use as having my turbo made hybrid an having a forge actuator fitted but goint to be driving the car down to amd for stage 3 map an dont want the actuator to be to stromg an cause damage before i get the stage 3 map fitted .... thankyou

 

[ibizacupra]

ask AmD

yes its called your right foot, and staying off the boost while driving down there......

true but dont want to cause damage, have you done much work on your car as ive got to change my turbo an was wondering how easy it is or isnt to do?

always left it to AMD and Bill to do the turbo changing side of things, based on lack of experience and time, as it has to be a reliable daily driver

depending on the mani, it can be a pig to do, but other than that, it is a case of unbolting etc, which change of fluids etc and bolting it back together (in a very rough descriptive kind of way)

ok mate thanks

no thats not what I said.
quite the opposite

So are you saying you reduce the turbine wheel?

and the turbo becomes laggier and but maintains boost higher up the rev range?

 

[wild willy]

what channel do you adjust for boost?
load scale turns things down but not >100%

channel 12:FF SEL Scaling.

 

[wild willy]

might be because carl is running APR software. I know with vtune you can turn the boost up maybe lemmiwinks picks up on some difference in the ECU caused by vtune so it will let the load go above 100%

This is true. I thought everyone who uses lemmiwinks who is remapped and able to alter thier boost with manufactures software can use lemmiwinks to increase boost also.
I didn't realise that Vtune is the only software available that will allow 125% increase in boost etc.
The only problem is the boost request increases in a linear fashion such that for me to demand 1.4 bar at red line most of the rest of the rev range demands 2540mb which efectively loses n75 control and the reason why i then run a mbc. Fortunately with Vtune , as the boost increases the map increases fueling also. A Diy way to run a hybrid but no substitue for a good custom remap.

get more flow, and if the compressor can pump it yes you will make more power.
turbine and hotside of k04 will limit flow, especially on hybrids, and they pump a lot of heat then

100% is the max value allowed on ch 12 load scale

Surely this would make the turbo suffer more lag as the turbine would be letting the gases pass by the turbine blades as opposed to rotating them?

Wouldn't a sports cat and bigger downpipe be the first port of call for getting rid of backpressure?

yep, bigger DP and race cat are one of the best upgrades for the 1.8T engine as this is a big strangle point

I believe the turbine is clipped to fit in the enlargened inlet (too big to start with)

so gasses wont pass by it, but will push more through, but because it is a bigger turbine to start with, its slightly slower to spool...hence laggier (thats my guess anyway, am I right?)

is'nt that what i have already said?

backpressure is in he exhaust manifold and turbo also....

I think the stock turbine is clipped in the stock turbine housing to let exhaust gases get out at higher than stock boost levels. This reduces backpressure that builds up in the exhaust manifold and combustion chamber?

 

[ibizacupra]

clipping turbine and or oversizing the bore means more slippage of the turbine, but more airflow is possible, as the turbine is less effecient ( so slower to get going slightly), but if the compressor is able to flow more, then the derestriction on the turbine will allow more overall flow.......... at the expence of initial spool

google it

Is there a problem here, I am only asking reasonable polite questions to someone who makes money out of people on this forum? I am trying to increase my knowledge base and if that is troublesome for you then I would have consider carefully where I spend my money in the future!

the only problem is you are asking a question which is already answered... making money off people off this forum (and every other vag forum) is completely irrelevant.

no matter. spend your money where you like... you dont see any other tuners on here offering their time to answer these type of questions... and then get asked the same question again.. a tad frustrating.. when you take the time to answer and read that time has been wasted as its not been understood.


have a google about to read more about this..
it can only help you understand whats being discussed

Dam I made a small mistake and missed a sentence, but I really like tuners who politely explain things to me, so I can understand what I am buying, how it works and the downsides to them, it may even be good marketing as well.

 

[ibizacupra]

i have been trying to explain things.
google about as well to get a broader picture of things. it will help

(no idea what sentance or whatever you missed??) - lol - remember I am not reading this through YOUR eyes. its easy to misread or read into things that are not there.
