Do any of our racers, or ex-racers have a ballpark idea of how much cfm the stock TBI will flow on the 7.4l engine?
I've tried to look up the part number listed on the TBI, but I come up with nothing.
I'm not looking to modify it, or change it out, but I want to input the right figures in my desktop dyno, so I can get an idea of what kind of improvement I should expect from my rebuild.

I think there is a site that rebuilds injectors, I remember someone sending his in on my Fiero forum. I believe they have specs. For all types of injectors on their site.
I’ll go see if I can find the link, just may take some time. If I don’t forget what I went over there for. lol

I believe this is the place but I really didn’t look to see what info was available, so you will have to do a search to see.
They are reasonable though when you consider the average price of a new injector is $150

I appreciate it.
If you find it it will be more than I've found so far.
I've seen a lot of replacement/upgrade TBI sites, and I was hoping to catch a statement of "flows __% over stock" At least then I could get an idea of what the stock figures are. But no one seems to make that kind of statement. Just my luck...![]()
