G60 charger pressure

[sparks 0]

im sure its been covered but here goes

 

just wondering what people G60s give out psi wise on what mods and stages

i think a standard on standard pulley is about 8psi ?

 

mines a stage 4 on a 68mm and gives out 12 psi max but i know its low due to its got 10k before a service is due i did have 14psi when i got the car

 

cheers stu ..

From the knowledge base:

 

"# 148 1000 0 (Atmosphere- ala no boost, charger is bypassed)

# 172 1200 2.9 psi (Your charger is dead or big boost leak)

# 192 1400 5.8 psi (Your charger is about dead or big boost leak)

# 211 1600 8.7 psi (Your charger needs new apex strips or big boost leak)

# 228 1800 11.6 psi (Great for stock pulley, Probably needs new apex strips if 68mm pulley)

# 242 2000 14.5 psi (Great for 68mm pulley on stock charger)

# 255 2200 17.4 psi (Great for 68mm pulley on heavily ported charger, hold on to your ass fast!!)

# 255 and up folks need to be careful with fueling, as the programming maps end at about 242 on the ecu. Dynotuning, and air/fuel/egt gauge, and custom chip recommended "

 

Mine is running 1840 on a 68mm pulley at the moment, but i'm due a rebuild.

my charger runs a 70 mm pulley with Jabbasport stage 4 porting, running - 14psi-(ish) according to the 1980 readout on the MFA. Although the charger is off a golf rallye. :clap:

 

mines due a rebuild too

On my old engine:

0.8bar from 2000rpm, 1bar (14.5psi) from 2500rpm, increasing closer to the rev limiter.

That's with a ported "TEC 2RS" charger (similar to stage5?), 68mm pulley, RSR outlet and some minor engine mods - after 45000km's still giving same numbers. Will be rebuilt in the winter though.. :)

 

On my new engine with a big valve head and loads of mods - I'm getting 0.7 from 3000rpm upto 0.75 on the top end, that's with a 65mm toothed pulley.. :wave:
