Northwind vs Torker 2
Has anyone replaced a Torker 2 with a Northwind intake? Any dyno tests or et improvement?

Quick question - are you currently running the original 8.5” 10-bolt rear end in your T/A ? And if so what axles/spline count and which limited slip differential are you using ? Thanks!

The Torker II runners keeping a good cross section way up the runners is difficult if you have a high flowing head, besides needing weld at the top of the port for 320 cfm E heads. The Northwind has good runner size and I would guess even a bigger plenum than a Victor. T2 plenum measures larger than a Victor plenum also.

My buddy Ed, made 810 hp with Northwind, but its a solid roller. 535 ci. To fit everything under the hood. Thats with 1” spacer.
I was a little surprised, of course it made more with the Victor I think around 835 hp. But its a street car on pump gas. Reading SD Perfromance testing where he says [quote ] With a CNC port matched Victor and CNC plenum (previous testing showed the modified plenum was worth 20-25hp) [quote ] i’m laughing because when I said my unport Victor vs me fully ported Gabby intake made 25-30 more hp over the unported Victor. It was question? LOL remember though my Victor was cut in haft and a big incase in platinum area as well as runners size. But also Pro System carb 1150 cfm.

My question would be whats your cubic inches? Just remember SD example is with a 535 ci. Which is dying for more intake if your in the 462 ci range you might not see same results. Just keep that in mind, I mean other then a back to back swap at the strip or dyno which probably isn’t worth the money and aggravation. Because other thing may come into play. Like jetting….. maybe

I'm kinda surprised there aren't more results and data out there for a 15 year-old manifold.

Maybe Im misunderstanding the intake heights, but I don't see how with the given heights we have in the "Intake Height" Thread that the Northwind fits under stock hoods, especially with a 1" spacer.
I have a lightly ported RPM, and have been considering a move to a single plane. The RPM with no spacer still requires a pretty substantial drop base. Is the Northwind notably shorter than the RPM? It seems to always workout that if you don't run a spacer on a single plane, you are giving up power, so I don't want to bother if I cant run a spacer. I had pretty much told myself if I wanted to do it I was going to be swapping hoods.

There is definitely a problem with the Northwind fitting under the hood. Ed told me, he doesn’t think it’ll fit with a 1” spacer, with out doing some hood modifications in his 74 Firebird. As it was his Victor was cut down when he was running the high port heads he’s sense gone with E-heads and Northwind, but as far as I know it won’t fit a 1” spacer.

Since any Plenum acts like a reservoir the bigger the cid the greater that need is .

5-7 isolation will reveal the better manifold.
2-1 isolation too. |

My RPM limited HFT cammed car picked up going from the Northwind to the TKII. It picked up even more going from the TKII to the ported HSD. I would bet the opposite would happen with your combo and that you will pick up .2+

Butler says the Northwind is 1.25 inches shorter than a Victor:
https://butlerperformance.com/i-3000...tegory:1291427 Summit says a Victor is 7.7 inches: https://www.summitracing.com/parts/e...7/make/pontiac And an RPM is 7.45 inches: https://www.summitracing.com/parts/e...6/make/pontiac So a Northwind should be about 7.7 - 1.25 == 6.45 inches. If you can use an RPM without a spacer, you should be able to use a Northwind with one. |

If we have two 600 HP engines, say a 455 peaking at 6000 RPM and a 535 peaking at 5400 RPM, does the 535 see a benefit going to a bigger plenum that the 455 does not see? And if so, why? Last edited by i82much; 02-09-2024 at 10:22 AM. |
