It shows just how close meth/pump numbers can be to…Read more 534WHP 532WTQ – One-off set of custom turbos from Vargas – Race Gas + Meth – New N54 Stock Frame Turbos/Stock Motor Record?

By PTF

Yesterday we managed to use Cobb to control an external Tial wastegate entirely, without piggyback involvement and make some good numbers. Boost control had to be redone from the typical way its done for internally wastegated vacuum operated turbos such as OEMs…Read more Custom single turbo – 18-18.5psi – external wastegate control, OEM solenoids, COBB flash only – shakedown runs
