I'm still a newbie on this thread. And to these trucks. I'm loving my 93 extended cab f250hd. I just swapped to a 5 speed, and I'm super happy I did. I just think a 5 speed is natural behind these engines. I've put in a good exhaust, a few gauges, fixed lots of odds and ends, and it's serving well as a daily driver.
Anyways, I've been absorbing all I can off this forum. Like watching the current performance overhaul Project Big Blue by Thewespaul and learning from that. Boy there's a lot to learn!
I want to use this 93 truck as my NA platform. I have a 91 "diamond in the rough" that I picked up and it will be my turbo platform because it has the nice banks sidewinder kit already on it.
I'm keeping this 93 naturally aspirated. I understand boost is the way to go for power, economy, etc. But I think I may have something up my sleeve...
I've been working hard to develop a new algorithm for header design. I think I've nailed it - this set of formulas I've built up should create a perfectly rhythmic pulse through the collector and provide the foundation for maximized scavenging.
The advantage to applying it to these engines is that I have a baseline of dyno'd trucks to reference. If I can come even close to a 10 psi turbo, it would be completely worth it to me. The disadvantage is there is almost no valve overlap, so scavenging may not help as much as with other engines. But I still want to try it out.
My plan is to build
1. a set of equal length 40" primary headers as the control
2. a set of headers applying my algorithm
3. and a set of headers applying my algorithm that follow the tri-y design.
One hour on the dyno cost $150 just 20 miles down the road from me. I want to dyno manifolds, equal length, my algorithm, and my tri-y algorithm and see the comparison. It should cost me about $800 to do this experiment if it all goes according to my plans.

I want to hear your thoughts on my primary pipe diameter because I am still hesitant. I'm thinking a 1 1/2" will be good because that should allow enough flow for this diesel staying below 3,200 and making 200-250 flywheel hp, while still maintaining velocity. It won't choke it though right? Or be too big? What is the diameter on those Stans headers?
What are your thoughts? Or votes? Or experiences? Thanks for the help. It's $150-$200 for materials to build a set of headers and I want to do good on the first try.
And sorry for being so long-winded, I guess I get too excited sometimes
Plus I have to explain why I'm not just putting a turbo on it haha!
