I agree..... Generally I don't put much into flowing the carburetor as part of the induction system.


Usually the biggest carb wins. Flowing through an empty baseplate sometimes helps see what's going on with the transition from the carb exit into the manifold runners. The flow bench is helpful for improving carburetor CFM and testing booster signal.

So…. TA Man you pulling the tiger and making the move to Northwind, you have room under hood to try it with a spacer.

Interesting thread. I'm just been playing around with a Victor 4150 I'm gonna try this summer. The Northwind is a 4150 Dave did for me. Victor difference of about 1" plenum height.

[Gach]

Are you going with 1050 on Victor? Or am I reading picture wrong

[chuckies76ta]

Yes 1050

Just as a comparison first picture is un-port Victor second one fully ported Victor. I was blown away in the difference in hp the ported Victor made over the un-ported one, that was just port matched to my heads.

Definitely looking good, going be interesting see how much you pick up

Ya hard to say. I'm just playing around with this intake to see what the car will do. I have the Northwind 4150, the Northwind 4500 and now this Victor 4150 which I'm doing. I'm gonna try all 3 this summer see what happens. I didn't do back to back testing with both Northwind intakes, but at end of season we ran the N.W. 4500 and ran a best number at our track. (10.12)

Interesting how thin the port divider walls are in the plenum on the unported manifold verses the port divider walls in the plenum are on the ported manifold.

Maybe this will help, when we dyno with the un-ported Victor and the 10.50, after a few pulls, he said you need more carb, so he’s on the phone with Patrick at Pro Systems, Who he deals exclusively with. Two days later carb shows up, first pull it picks up 30 more hp, turns out its a 1150 cfm. I’m not running a big roller 739 lift. 265/276. 505 ci. But they are wide port heads.

I may run out of room..torker 2 with a 2inch was pushing it

Time to get out the measuring tape. Wow 2” on the torker 2 nice

That because both intakes are ported, Gach is confused again.

NW doesn't need a spacer because of plenum volume, it needs a space because there is no turn from carb to runners without a spacer and because it needs some room from floor to carb.
With a spacer the NW looks to be a pretty good intake.

First time I dynoed my 462 I tryed a bunch of intake's and the NW came
closest to my Dom-Victor 2-inch spacer on the NW and 1 1/2 on the victor
The victor has not been ported either the differance was I think 6 HP
I put the NW on my 57-wagon.

I also wonder does this Northwind need a spacer..the top of the runners are very close to the carb mount?

By all means try it and report back. You will be a pioneer in this field.... Or a maverick .

Imo to make it worth while a spacer is needed. They squashed that area to help with hood clearance but it's definitely costing power.

I was looking at that ...it has really high ports so at least a 3/4 inch spacer to get the throttle blades up higher.

A disadvantage of owning the coolest car ever made.... I purchased a quarter inch spacer off E-bay. The guy advertised it "for when you need just a little bit" ..... He obviously didn't own a Firebird.
