0.5 bar at around 2900rpm
1.0 bar at around 3100rpm
Hope to see some improvement.. Collectors are far from optimal but I got the system from a friend fairly cheap..
Will let you know the numbers for the stainless later on (lots of snow)

Ok, back with some info from the first spring ride, track the car fairly often and I feel the 4-speed gearbox is the biggest setback with these cars on the track and a broader powerband was on the wishlist.. and I got it
(Euro exhaust figures above)
And with the stainless headers
0.5 bar at slightly under 2400 rpm
1.0 bar at 2700rpm
I was hoping for some improvement but this is almost unreal..
