 More progress in the early hours. #boostcave #minimumpsi #maximumglh  Got a few minutes to work on my Omni GLH this morning. Modified one of the Driven Innovations EVO plenums and took some volume out. Chopped down and shaped the end tanks. Set it up for a "large" 58mm throttle body over the stock 48mm. #maximumpsi #turbododgeshit #turbododgesareshit #stillgonnasendit
 Modded F80 in for spun crank hub repair. Email for info and pricing on our keyed crank hub. We have been testing this design in several high powered F8X BMW's including our record holding shop car. #maximumpsi #bimmerclinic #bmwspecialists  Really sucks losing such an iconic location drag strip. We have used this track to set numerous records on many platforms. I only hope Atco and island are around for the long haul.
