Thinking again and it hurts
There are some that don't want or need a turbo for reasons of there own.
I have one that will never see a turbo myself, so heres what I have been thinking. Pretty often someone mentions headers and gets answers that you only gain 7 horse power so there not worth it. Others claim they really woke there rig up, more power and mileage too. I don't know or even pay attention to dyno numbers, I do however pay attention to my butt dyno and fuel mileage.
I have never had a set of headers, but know for a fact that opening up the exhaust with a good set of duals makes a huge difference.
So look at the bend in the back of the drivers side manifold and tell me a good set of tuned headers will not be worth it.

In defence of ford (my favorite non guberment owned auto co.) where they smashed flat to make that 90 the widened it out a little to get a little exhaust out. But there is no way it is even remotely tuned with the other side.

well,here's what iv concluded about headers.
1.headers over manifolds largest gains i think,is not so much as flow,but that they scavenge.
2.diesels do not require this scavenge effect.
3.there is only 1 source for headers,and they cost as much as a used turbo,and could never compete with that no matter how good they are.
i don't know how true any of this.just what iv gathered from reading other people lol.
of course #3.is obviously true.

Pulse tune scavenging helps any na engine simply by creating a low pressure state at the exhaust valve at the time of opening. Good quality pulse tuned headers are hard to come by and allways very expensive. That said they are much more benificial on 2 stroke engines and pretty much a 2 stroke motor bike won't run without one. My uncle used to build tuned headers for racing purposes and there is much maths and swearing involved as well as many man hours. In aus the kids all buy extractors thinking they are the same as headers when in fact although they may breathe better the are not tuned and can sometimes be detrimental to the tuning of the engine. Once again that said if they are buying cheap extractors the engine is probably not that highly tuned anyway.
PS Star sit down whilst thinking or you may fall over.lol.

yea ford 250 but like I said some folks doesn't want a turbo.
Take a good look at where the back of that bend in that manifold is. It is right in the middle of the exhaust port the air flow has to move forward as well as down. There is no way headers will not help this.

If one had the time to do it (as I hope to in the future) they could build a set of custom manifolds for these engines. Sort of like a set of shorty headers. My biggest hold up is not haveing an engine that is out of the truck to do the r&d work on. It is just a little tight in t he truck and I have to drive it every day so pulling the manifolds on and off is out of the question. Maybe this summer will be a dry one and I can ride my bike back and forth to work and try this out.

Oh ok. But seriuosly I do plan to try this when I can. I started thinking about as a way to mount a turbo in a different location but if you can improve the flow of the manifolds and reroute them so that they get to the turbo sooner it might be a help. I have read that the hotterthe gasses coming in the better it works and the improved flow would have to help with spool time as well.

you would be amazed at where you can squeeze or hide a turbo. Ever seen the remote turbo kits for camaros or firebirds?? Would suprise you how well they actually work.... Yes there is more line and tubing to run, but you can place a larger turbo in a larger space!

i dont see any issues will oil flow on the return since to oil is under a little preasure. I know STS makes a ton of kits for many many vehicles. And they have proven to be as reliable as any other setup.

LOL
ok,so that is pretty sharp turns there yeah.fab us up some customs Star,if they're reasonable,we will buy them.
do they turn down quickly so the pipes can clear the firewall tho?
