Boost level on a stock 130

[muddyboots]

Just been doing some logging with vag-com on my Passat, to see what state of health it's in.

Anyway, I logged some runs up a biggish hill flat-out in 3rd gear from 2000-4300 rpm.

At 2000 rpm boost is 1.35 bar, which it holds till around 4000 rpm, then it starts to drop off down to 1.22 bar at 4300 rpm.

Does that sound about right for a standard 130, or is the boost a little low ? I can't remember what the stock figure should be.

Also, throughout the range where boost is maintained at 1.35 bar, the MAF reading is around 1050-1100mg/R. That sounds healthy doesn't it ?

 

[stoneyfordNI]

yep all normal , meant to be 1.34 bar peak

 

[muddyboots]

Cool, so it's healthy and ripe for remapping then

 

[stoneyfordNI]

ooh yes my remapped 130 ( custom code 2) sees 1.67 peak and still 1.43 at redline

 

[basstard]

are you sure stoney? thought it was 1,3 all the way up and 1,6 peak?
there should be an old thread with paulo talking about this [strange eh?] so so a search muddy,,, glad to see you've bougth the sleeper then

I'm without home connection again at the mo,,, it's already a week and considering that last time it took those tele2 b*stards more than a month to solve the prob I dread now to think how long it will take this time,,,

so see you next year you all guys,,, just came for a quick hello,,,

 

[stoneyfordNI]

im sure its 1.34 peak then trailing off ,, but il relog 2moro , cupra 160 peaks at 1.55 i know that much ,

id do it now if i wasnt wiped out

 

[muddyboots]

There is an old thread that I started about PD130 boost pressures, but read through it and don't think anyone actually mentioned what it was.

 

[stoneyfordNI]

some old vagcom data , revs vs specified boost

2079 1611.6
2247 1734
2415 1785
2604 1836
2667 1020
2877 2346
3213 2346
3612 2346
3864 2335.8
4095 2295
4263 2254.2
4431 2172.6


absolute boost pressure so minus 1000mbar

 

[stoneyfordNI]

thats the graph



so 1.34 bar boost it is

 

[muddyboots]

That looks virtually identical to what I saw tonight. Ta

 

[stoneyfordNI]

no probs

Muddy -- bloody hell! Didn't take you long to roll your sleeves up and start on the remap trail

One tip I picked up from a VAG dealer, it may be worth checking (and possibly replacing) the elbow hose from the top of the intercooler to the plastic inlet pipe that runs round the block.

Over time these can get soft and collapse under boost. Also the clips that retain the pipe too.

pressure seems fine but don't you need to clear out the egr / manifold and drain the intercooler before you go any further? did you find the heater plugs/ cheers Nic ps Carlo what's Italian for manyana, I thinkl it's "directly" in Devon which is even slower!!!

 

[muddyboots]

Nic : One step at a time, haven't even got round to taking the engine cover off yet

Craig: Thanks for the tip, I'll have a look. Did you know that Haynes now have a manual for the 00-05 Passat range ? I've just ordered one direct from the Haynes website. Not sure when the remap will happen, gotta sort the tyres & probably get some decent shocks on it first. But Simon Coe from Upsolute has quoted £295 all in, so it's very tempting

 

[craig-pd130]

Interesting about the Haynes, might have to get one

Upsolute for £295 -- does that include VAT as well? Bloody good deal ... I've just arranged to hang onto mine for another 18 months, and it's out of warranty .........

didn't understand the rest [the devon part] sorry,,, do I have to feel dumb???

 

[cheshire cat]

sorry my Spanish and Italian are both non existant except for Peroni and Morreti

 

[muddyboots]

Nic, thanks for your PM earlier, tried to reply but your inbox is full
