Great test and very informative but its important to note that a change in cam profile such as something with more over lap for example can throw those results out the window and have a very different out come. There are many different factors to consider, and all engines and set ups should be tested individually. Keep up the good work and look forward to more testing on different combo's.
So what you guys basically were saying, and correct me if I'm wrong; but if I add a 1" spacer on top my Performer RPM AirGap intake. I can squeeze a bit more horse power in on my power curve? Please tell me yes. I'll get a spacer right now.
haha that's awesome! I've been looking for a video like this for SSSOOOOO long, thanks guys, i'm actually putting a Performer RPM manifold on my 283 later on this week =]
Cool test. The divider drop is more important with carbs which are relatively big, in other words something you need for the nice big horsepower number. Always use the open spacer to test first before you mill down the divider, cause it doesn't always work.
i think on the performer intake i would have used the spacer from edelbrock that takes a square bore carb to a spread bore manifold and tried that it just seems to match the plenum from the design of the spacer so no air is leaking (whistling)and the gasket doesnt get saturated with gas like i seen when you had the open hole spacer which seems to work with wot pills or racing but for daily driving in stop and go isnt the way to go..just my experience.
Pontiac guys have known this for many years. Except we only cut down the back half of the divider so the secondarys take advantage. Test have been done on this with regular performer and Qjets and that lil trick will definitely add power and smooth everything out.
so what they're saying is if i get my rpm performer intake and gap the middle of the wall i get better performance? and if thats it then how big is the gap and depp in and how long?

How come 1 5/8 headers? Wouldn't 1 3/4 headers match the combo better, especially with the Victor jr?
