The NW has a lot of port taper compared to the T2. It also has shorter runners. One of three things will happen when compared to the T2;
1 the car will go faster 2 the car will go slower 3 the car will run the same |

Was that on the 463 in the 78 T/A? What is the ported HSD intake, a real HSD or the tomahawk that was cast after a SD ported HSD? Just curious which it was since I have a tomahawk I was considering trying vs the SD ported 71 HO intake Im running now on a 4.25 467.

Combo in the 78 TA now dyno'd identical with a SD modified HSD (pattern for Tomahawk) as my fairly ported T2. 525 HP conservative dyno 550-575 HP based on weight/mph

Definetly that or possibly something else.
But seriously IMO if you find a gain it won't be much. If you can borrow a NW or find a deal on one it'd be fun to try. If your paying full retail plus shipping I'd do something else with your money. We tested a NW against an RPM on a 630 HP engine. Maybe that guy will chime in. I don't recall the numbers but the RPM definetly looked better for a heavy street car. |

That's interesting, so it looks like you can make 600 hp with a 275 cfm head assuming you use a really long duration cam, if I am reading that right.

What my RAIV 400 did when I swapped on a T1!

There’s all kinds of software out there, but the real software is the guys out there who make the real hp. The amateur software builders can only surmise. How it all works.

One could make 600 HP with a stock iron head that flows 220 cfm or at least come darn close.

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.
