1999 10th Anniversary (NB8A) 1.8L
Before: Basically stock, only mod being an APEXi "Power Intake Kit" - 102HP (~76kW)
After: As above, with Loch Stewart extractors & Trust/GReddy exhaust - 105.7HP (~78.8kW)
The only other thing worth mentioning is that the "before" was done early on a very cold morning, and the "after" was done in the middle of the day which would have reduced the power slightly, so I may have gained more.
What's really interesting is that it shows I gained ~3HP pretty much across the entire rev range.
