Some people have asked for a pattern....Can't go out and buy graph paper at the moment, so I was able to bring some up on my laptop, then take a pic....the grid squares are 20 mm each.....Not sure how to adjust the pic/printing size so they are right on a printed sheet.......(Anyone know how?)

So did you dyno test before and after the mod or have some other way of knowing this made any difference?

Testing; Before installing the new ported manifold, I tested the car by going out to the Dublin grade on 580.....In Dublin I headed up hill (Going west) with a 5-8 mph head wind, and also with a 150 lb passenger. In 4th I was able to get the car up to 4500 rpm but then it basically stopped accelerating.
After installing the modified manifold, I took the car out (With that same passenger) to Dublin and headed up the Dublin grade again....It seemed to more rapidly accelerate up to 4500, and then continued up past 4700 and was still pulling. Not a huge change but noticeable.

This was the only testing so no....No dyno.....

Thanks for putting out the template!! I'm saving it into my Fiero 'to do' folder, so I don't have to find it again later
