here are a couple pics of my cut stock air box.

i added an msd manifold, LT5 tb and rotofab. the car picked up 14 whp peak and lost 0 tq. it gained 35 whp @ 6500 rpm. ultimately gained over 2 mph from only "14 hp".

what im saying is the car trapped 121 with next to nothing done to it (cut stock air box, exhaust, ported stock manifold & tune). the next 3-5 mph were at a steep cost.
do you know performance numbers for ur 1st mod. hp and track times. for airbox n e85
