F20C Turbo Manifold

admin

This setup is unique in its own way. I just finished building this for a customer that is installing his F20C into a classic RWD Ford Escort. I was glad to be approached with the opportunity of doing something unique like this, but the best part is the manifold is now being shipped off to Trinidad. I wish this setup was local, but I’m glad that my work will now be overseas and put into its paces. I will try and post more updates and pictures once I get updates of it installed in the car motor and manifold. Keep Fresh Everyone!

Reply:That looks amazing, great work.I would loooove to see the escort that it will be going in. Thats going to be a bad *** car. Is it powered by a Cosworth by chance?Nice work man.

Reply:you like working with that schedule 10 stuff?
Reply:yea, i dont mind it. thin stainless is nice too, but for the street car turbo apps this tends to be better.

Reply:wow, equal length, Y'd off for the waste gate right after the collector merge... really nice job, may not look it but I know that is a ton of work ... is the turbo going to be suspended by the header alone or will it have any sort of support bracket too?miller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....
Reply:Beautiful work!  Do you know if this guy has a build thread? Have you ever made a manifold for a Ford CVH?

Reply:I'd bet it was an educated guess, as the 2 common choices are schedule 10 or schedule 40, but sch 40 is almost never used when you go to stainless... schedule 40 is ~ twice as thick & usually is only used for mild steel manifolds...miller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....
Reply:you can use thin wall stainless, but it must be back purged or use something called solar flux which is like back purging.

Reply:isn't equal back pressure for each cylinder better?
Reply:For some reason I can't see any pictures.But those Mk1 Escorts are really nice, my mum used to have 1300e in 74ish. I used to pan the living daylights out of it around the disused WWII aerodrome we lived next to. I was only 10 at the time.  Sure wish I had it now, they fetch big money these days.editdoh, I can see them now. Fantastic work

Reply:equal length insures that the pulses merge at the collector with the least resistance, it causes the pulses to not collide... it's kind of like a highway merge... you can either go: one car this lane, one car the next & so on, keeps traffic flowing much better than if 2 lanes had cars entering at the same time & colliding... it def does increase efficiency... now in a turbo manifold this isn't as critical as a NA build because this doesn't come in to play as much while under high load because at that point the manifold is under so much pressure that back pressure becomes a limiting factor too, BUT it does still make a difference, can reduce turbo lag & also help make a little more power before boost actually comes in & can help spool quicker, re-spool quicker... once the manifolds are under a lot of pressure though then it does start to make less difference... all other things being equal then equal length is better than non, even with a turbo... will improve overall drivabilty on a street car, lets not forget that most street cars will spend less than even 5% of it's time under boost in most situations...miller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....

Reply:well personally I've heard, seen & read many arguments for both sides, but in the end I tend to see even the nay sayers saying stuff like it doesn't make that much difference or the benefits are negligible, and I've seen several turbo guru's say that it does make a difference too, so what this has me believe is they can be at least marginally better in some areas & in some cases.... I can't see every cylinder seeing an equal volume in the primaries before the collector being a necessarily bad thing, maybe it's just an attempt of going the extra effort to try to build the best you can? especially since your not going to have the luxury of computer modeling & analyzing & dyno testing multiple designs & configurations to really know, why not try for ideal the best you can .... overkill? maybe, but I guess overkill isn't always such a bad thing... your probably right in that you wouldn't be able to tell that much if the lengths were off by a few inches in overall output but if there's a chance it can potentially make it even marginally better in some areas then why not? I think I feel better knowing my primaries are all the same 16" length at least, guess I'll never really know for sure so keeping them equal was about the best I thought I could do miller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....
Reply:The whole equal length thing sounds good on paper but we know that things don't always work out that way in the real world. Robert Yates did a lot of testing with this and found that the shortest least restricted exhaust worked most efficiently. In an equal length setup usually you have some straigh tubes while others make 180s and very tight bends and such. Doesn't seem as efficient too me. That being said your manifold is awesome. Not knocking it one bit.
