...I'm just back from another trackday...man this is wearing me down.
Skassa>>I did 1,21 laps on Gellerasen in Karlskoga, STCC laps it in 1.07-ish - so I am quite happy with that time.
The fastest cars from the Porsche club does the same track in 1.17.
The header is well worth it - but you will need to have a mappable ecu, and a proper turbo.
The quality is second to none.
I am around the 90 mark with an uprated (Walbro) fuel pump running ~12:1 in row 8 all the way up. I will need to do something later when the temperatures goes down...
