d4f and d4ft camshaft specifications

[Adeyspec]

My other Interest goes to your Turbo .
I know , original is not perfect .
Exhaust out to Turbo in is far away from good , you change something ?
From Hand with a Milling Cutter no Problem .
The Exhaust Pipe have the same Problem like my D4F , 40mm .
The Exhaust out from my D4F i make 48mm and switch to a 50mm Pipe , is much better now .

on the stock turbo i have a protoxide decat pipe and a full exhaust of the same diameter, 50mm.

the problem i have is the turbo runs out of flow higher in the revs, i dont want to increase torque too much more so i want to flow more at higher revs. I currently have 147ft lb of torque but the turbo dies off at around 5500rpm, id like to hold the same torque up at 6500/7000rpm so have started mounting a bigger turbo on a standard manifold.
