Certainly would be unique, but too much effort for me to make that work with the PF4 system. The Holley 1000cfm throttle body is a bolt on and go solution.
You could think of it that way I suppose. I think it's a different animal myself.Can one equate the progressive linkage of the PF4 to a quadrajet type mentality? I may be way off here.
I watch that forum frequently just for knowledge and I see that the moderator “Nate” is like big brother for edelbrockAside from the velocity stack idea working awesome on the FiTech throttle body, I decided I'd put even more FiTech into the PF4 effort.
I replaced the little 29lb Edelbrock injectors with 40lb FiTech injectors I had from the Go Port setup. Motor is much happier contrary to Edelbrock forum moderator wisdom insisting that I need to make more horsepower to use bigger injectors. Same moderator would also say they are the wrong injectors and insist I use something Edelbrock has tested. For example, their 35lb injectors. Well yeah, that would be correct for guys that don't want to spend any time tuning EFI, but not so much for me. I used one of the 35lb 43psi SBC calibrations that matched my cubic inches, vacuum, and camshaft profile. All I had to do was pull some fuel for Idle and Cruise with the Fuel Modifier function to tame the trims. Pulls like it should now. Much stronger than it was with the 29lb injectors.
I'll be trying the 60lb Siemens Deka injectors in a couple of weeks. Edelbrock forum support said I needed to be making 700HP to use em. I told the moderator they worked on my Go Port setup and he deleted my post. I must have gone outside the lines of the Edelbrock coloring book, along with a few more where my crayon strayed into the experimental zone.
Interesting, but I'd never take that tuning approach, because I don't like the progressive linkage, and it would be time wasted for me. I prefer to concentrate on changes that make a significant difference in power delivery over the entire throttle range.You can adjust the TPS a little on the Edelbrock throttle body....Why. Because at start-up. It's at "rest position" is now 0.
So. If you move it a little clockwise ( as you face it ) WOT ( usually 75% of throttle of the TPS ) will now happen sooner.
It would be better to try this trick, instead of adjusting the secondaries first.
Or put another way: WOT can start sooner or later, depending where the TPS sees 75% at.
Completely agree with Schwany here concerning anemic feel with the Proflo progressive linkage. I don't have a lot of time on my PF4 set up yet but response is nothing compared to the Fitech I was running. Just converted the PF4 to 1:1 linkage today. Now I need the snow to melt again so I can test it:surprise:
Does the snow ever melt in MN? :smile2:Completely agree with Schwany here concerning anemic feel with the Proflo progressive linkage.

I don't think they want the inexperienced audience that generally expects things to work out of the box messing with the throttle body. It would end up being a support headache. Market for the 1:1 throttle linkage is too small. I'm thinking the majority of Pro Flo 4 4150 kit owners never even think about it.77sonic. Looks nice.
And looking at the 2 different setups on here, they both appear to be relative simple. I'm confused why edelbrock dont have this an off the shelf option. Seems doable at their level then would could have the option.
