Last night Soulster and I stayed up late and did some ABA testing. On his car, we could take off the intake pipe at the air filter. This leaves about 14" of pipe or the same size as the warm air.
We did ABA testing on the same stretch of road the I used for my mod testing. He drove and I put the data into a spreadsheet. Once I got him to do testing we kept going and did his upper grill block, folded in the side mirror, and removed the side mirror. Once I process the data Soulster will post it up. More data for the wiki
