Project Saab 9-3 Lillebror

Last week MapTun Performance posted a teaser of their tuning project in the dyno and it is now time to tell you more.

This car has been presented before as “Project Saab 9-3 Lillebror” and it still is the same concept with both turbo and supercharged engine.

The last time they worked with the car they could not get the supercharger to work as they wanted, which then forced them to some upgrades, now the car has a new type of supercharger and this time it worked really well.

Lillebror (Little brother) produced 460HP and 530NM in dyno, the fuel lines was the only thing holding it back, but they are not going to stop here. After some modifications and replacements MapTun team are aiming at 500HP.

Lillebror was born as a 2003 Saab 9-3 Linear and when our technician P-A together with his team put their hands on it this is the result, not only is it both supercharged and turbocharged it’s also four wheel drive which makes it even more fun.
