The bottom line on this whole intake deal is really very simple, when you think about it. Lets say the head flows ( just as example ) 325 cfm now you bolt that intake up and with the intake bolted up, and flowed through the intake it drops 20-25 cfm, so actually you really only have a 295-300 cfm head. So how much of a lost that head is seeing with a Torker 2 vs the Northwind. So in others words and this is a known fact between the best out there. And I mean real numbers. A 30 cfm gain access the board is worth 10% increase in hp.
The other thing asked yourself why a Northwind needs a 1” spacer to see any real hp gain. It’s called plenum area. For same reason why a tunnel ram makes more hp. The same goes for runner length. It’ll be really interesting if he makes the change to see what he picks up if any.
There’s so much that comes into play track conditions, perfect weather.. track elevations.
