Hello Folks,

 

Is it worth the money getting your charger upgraded above a stage 4 conversion ??? :roll:

I am using a 70mm pulley and I think I am loosing a wee bit of power due to my exhaust not enough back pressure I am told.

Perhaps you should go for a 68mm pulley. You wont lose power with a large bore exhaust, you may lose bottom end torque but unlike turbos the charger doesnt need back pressure to perform.

sorry dubcharged, but just wanted to pick you up on something, turbo chargers do not like back pressure at all.

 

the best exhaust on a turbo charged car is no exhaust since you want the largest pressure ratio accorss the impeller as possible in order to get it to spin as efficiently as possible.

 

The only time you would ever want back pressure is before the turbo has spooled up, at which point the engine is effectively normally aspirated.

 

On turbocharged engines, the torque gain realised by the turbo far exceeds that which comes from having high back pressure when offboost, so most of us choose to remove the back pressure just to bring the turbo in as soon as possible.

Been saving for a while. Wanted to do all at once (saves on workshop time)

Also Chip would have to be changed with different specs on engine. Only one chip change instead of 2 or maybe 3.

Had car about 6 months now and was happy b4 :) now :D :D
