Photo 2/4 | Ford F 250 Front Three Quarter Open Hood | Recently, we dyno tested a 6.4L-powered Ford truck that was on a race tune, which put out 509 hp. With an open intake, the truck picked up another 18 hp, checking in at 527 hp and roving the stock filter was indeed a restriction.
Photo 3/4 | 1997 Dodge Ram Head Studs | Using head studs (rather than bolts) is a good way of increasing clamping force and leads to a much stronger head gasket seal, which is important as boost pressures rise to double or even triple that of stock.
