I think we need an intake dyno shootout, Same car and all the intakes...in one day.
Start off with a stage 1 car with a stock intake, put it on the rollers and see what it gets.
Then one by one get the intakes on......
BSH
Neuspeed
Carbonio & filter
DBilas
Forge
EVOMS
VF
ITG
HKS
Should make an interesting day, but it is only theoretical as it would be a logistical nightmare to get them all on
