Hi i have already experimented a lot of Vf in my car , (PASEO, 5EFE ,all forged etc), the only turbochargers that i have no possibility to review is the VF34 and others Td04 like the RAcetech Td04. The vf 23,14,28 are laggy for my car ,but the VF35 with a billet wheel is equal to a td04L in boosting situation, and this vf35 seems better than some td04 hybrid ...(TD04 L15/TD04/L19 TD04H 15 greddy) Now i am with a VF35 with a Billet wheel 6 blades instead of the 11Blades I do not know about the Racetech td04, but i have seen some hybrid as slow as a vf ,and on some video (youtube) as quick as hell ( racetech)
