The slow arms race to 275+ at the wheel continues. The most recent addition is a finalaized, perfect fit V-stack. Look Ma no couplers, the stacks seal against the raised flange on the TB and there is no lip or gap internally. These things are built like a brick *hit house, 100% infill with Carbon impregnated nylon. They’ll be part of a new system, one that I hope will push me over the 275 mark with a filter in place, on 92 pump gas, no tricks, just power.
