Hello, i use ABF shafts with original hydraulic lifters at my VW POLO 6R to autocross. I have skoda block, 144mm conection rods, 83,5 bore. turbo is Garret G25-550. At dyno i have 520 HP and 610Nm. Its ok for me but we havent power at lower rpm(250hp at 3500rpm). I think problem are camshafts. Can you tell me which are ideal for turbo aplication ? ABF, KR, PL some numbers? Many Thanks Jirka Bret, CZE
