[Viper99 0]

If i floor my G60 through all of the gears i cant really feel my charger kicking in but if i have the reves about 3 grand in any gear and step on it i can feel it. Is this ok? Is this how the normal stock boost in suppost to work?

Please help

Thanks

what do you mean when you say you "can feel it" ??

Shouldn't be a kick with a G60 IMHO. Sounds more like a short ECU pipe or belt slippage maybe. Is the car chipped? By who?

How to test your boost levels - UK spec cars

 

1. Start Engine

 

2. Move the MFA selector to "2"

 

3. Press and hold the MFA end button (keep holding)

 

4. Stop engine

 

5. Start engine

 

6. Release the MFA end button.

 

7. Press the MFA End button one time.

 

 

You should now see 450-800 readings fluctuating with idle. Anything higher than 800 is not right (vacuum leak). Much less than 450 is probably too much timing advance.

 

Go run your car!!! 3rd and 4th gear to REDLINE. Carefully note the highest #'s you've got.

 

A pullied charger should not make less than 11.6psi, and even so, thats weak. A Stock charger should make ~~11psi in perfect shape!

 

EURO Hg(#'s of boost/vacuum) Comments

200 -23.7

400 -17.8

600 -11.9

800 -5.9

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

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

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

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

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

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

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

 

2000 and up folks need to be careful with fueling, as the programming maps end at about 2000 on the ecu :) Dynotuning, and air/fuel/egt gauge, and custom chip recommended
