So I see a lot of the carb guys with super victors on here run 1" spacers under the carb. I have a EFI version of the super victor with accufab 4150 throttle body. Will I benefit from a spacer? what kind and size should I use? I will also have a nitrous plate under this as well. Do you just stack them with gaskets in between?

Setup is a 408 with ported TFS 245's with ported super vic 4150 and Brian tooley custom cam. This is a nitrous motor which will be sprayed 200-400 shot range.

NO need for it man. The only spacer I'd run under a 4150 is a nitrous plate.

I'm not a nitrous guy but NA it should help, haven't tried it yet, but will next year.
Ask in the Nitrous Section.

I've never run a 4 hole tb, but I run a 1" under my elbow. I do it for extra plenum volume.

Both pictured are super vics. The one on the left has a 1" and is what I run on the truck. The one on the right I use to dummy stuff up.



I don't think I've ever seen anyone test and say that it hurt it.

I would use a 1-2" open spacer.

I don't think it could hurt with efi. I always thought more plenum volume the better.

I have a 1" open spacer and nitrous plate between the throttle body and intake. I was told with a single plane intake the more space you can get between the throttle body and intake the better.

I think that the addition of spacers in a 90* elbow set up probably help air distribution as well.
