How accurate is the liquid gauge?

[Jamesrowe]

Hey all, i bought a liquid gauge earlier in the week, when i checked the boost pressure it peaked at 22psi and was averaging around 8 psi, as far as i know my car isn't chipped, and i thought it was ment to be around 12 - 14 psi. Any help would be great.

Cheers, James

its fairly accurate mate, 22psi.... big boost spike there.. any running issues?

reads data from the ecu, only difference from mechanical guage is a millisecond slight delay whilst it collects the data.

 

[Jamesrowe]

Oh right. It seems to run fine, the only thing i have noticed is that when the engines warming up and you put your foot down it feels like the clutch is slipping, power a bit juddery sort of feeling, but when the engines warmed up it goes and runs smoothly.

When i bought the car the bloke i bought it off said it hadn't been modified in any way, i serviced it last week and noticed that it had a forge dump valve on, but the dump valve looks different to the 007 ones, could the boost problem have something to do with that?

oh yeah, i've got an 02 plate lcr 210.

 

[james walker]

could well be mapped mate.... do you have acces to vagcom?

could be the forge 006, slightly larger... did the valve have a big trumpet on the side by any chance?

 

[Jamesrowe]

No, i don't have acces to vag-com, i will have to purchase it i thinks. Will that be able to tell me if it's mapped or not. I'm not sure if it's got a trumpet on from the top of my head, all i can remember at the moment is that it was held together with allen key bolts, and the pictures on the forge website looked different.

 

[james walker]

does it say forge on the valve?

vagcom will tell if it s mapped yes, if you run logs youll see boost requested vs actual, maf readings etc... all will be a give away.

 

[Jamesrowe]

i see, will have to purchase one of them when i get paid then i think. Yes it does say forge on it.

which one of those does it look like?

 

[Jamesrowe]

the one i have looks alot bigger than them, with visible allen key heads on top of it.

 

[james walker]

probably the forge 006 dv then... older version of the 007 and bigger.

id say it was mapped tbh, wouldnt really be worth putting on on if standard boost.

need to run logs really, but if boosting 20 odd then it will be mapped.

 

[james walker]

should boost 22psi then hold around 14 id say for mapped lcr.

on the liquid guage, go into bhp readings and run a power run, from 2500k in 3rd gear to redline and see what bhp it reads... do the same for torque mate

thatll tell you.

 

[Jamesrowe]

ok mate will do. Thanks for your hep, i'll give it a go when i finish work and let you know the result. Cheers again.

 

[Jamesrowe]

Done the BHP programme on the liquid gauge, it came up with 233 bhp.

 

[adam cupra 20vt]

Is it a cupra R you have?

Thats not far of standard bhp?

 

[Jamesrowe]

Yeh its a cupra r 210 model, the bloke i bought it off said it was compleltly standard, but its boosting quite high according the liquid gauge!!

 

[adam cupra 20vt]

Those liquid gauges measure the peak Lee69 has one on his LC and although I think it shows 16psi peak it only boosts 9-10psi 99% of the time.

Does it show 12-14psi most of the other time and does it always peak at 22?

That doesn't explain why your 210 is reading 233..... could it be mapped and not running right or could it be other mods making it 233?

 

[LEE69]

There is a boost gauge on it, but it does record the peak boost.

 

[Jamesrowe]

The only mods its got is a pipercross panel filter and a forge dump valve. It always peaks at 22psi, not sure what it usualy boosts at.

 

[james walker]

well 233 is 23 bhp up on the 210... so id say stage 1 mapped..

do the torque measure aswell mate, see what that records at.

liquid usually under reads bhp, does on mine to 5-8bhp, so add that on... 241 bhp, so id say definatly stage 1 mapped

would like to see proper vagcom logs to confirm though
