Shane, only way to know for sure is to call Kyle and ask him about it. Im pretty sure he would be able to do it. Hes a nice guy and easy to get along with, im sure he could do something for you.

i have one of Kyles high mount manifolds on my 25/30, awesome quality and its thick not thin stainless and flows so brilliantly as does Ariels (ISLEEP) plenums hehe free plug mate ;-)

Um Kyles manifolds arent stainless steel...they are just plain mild steel...unless he made a one off special for you or something. Hes totally against the use of s.s for manifolds. But they are of awesome quality, im very impressed with it so far.

yep steam pipe, thats why i wrote in my post "not thin stainless" sorry if i didnt make it clear meaning that i didnt have one in stainless... as u can see in the pic, perfect quality

Ok can someone tell me what their version of steam pipe is? Cause in boilermaking terms steam pipe is chrome/molybdenum pipe used in power station boilers. Now the manifolds, in trady terms are sure as shit not made of chromemoly pipe. They are just mild steel pipe, where the term 'steam pipe' comes from is beyond me. Someone enlighten my humble metal fabricating brain please :)

Cause im getting confused here.

Cheers.

I've got a niggling idea that steam pipe is to do with how the pipe is bent, like heating it up with steam and bending it maybe? (smack me over the head if thats a rediculous idea lol)

ok well once again, it wouldnt be a steam pipe...it would be a mandrel bend. So im lost. Yeh shane, that pipe aint heated up with steam and bent. In most circumstances the name of the pipe comes from its main application in its line of work. Unless there is something ive missed i think this is just a case of mismatched term and its stuck to it, or 'steam pipe' is the new 'modern' name for mild steel pipe.

Yep, that sounds right, the blokes next door to us have one, got a ball on a little arm that sits inside the bending radius and stops deformation of the pipe like what happens with plain press bending.

moral of the story is the manifolds are good, and im calling it mild steel pipe :ninja:

Steam pipe bends are mild steel cast bends(called black steel), not mandrells. They are called long or tight radius butt weld(you can buy them with a thread on them)steam pipe bends in the blackwoods catalogue. I think they are called that as they are used extensively in boilermaking, also handrails? They are available in two different thicknesses and manifolds are made of the thinner ones(approx 5mm wall thickness-grade 40)there is also a grade 80(10mm wall thickness!!)hope this clears it up

just to add my $1.29 to the steam pipe stuff, yes there for steam. a lot of factorys run off steam power still. sheridans (quilts/sheets) i did some work at years back and most of the machines there ran off steam.

The stainless exhaust manifold we got on the race car is shithouse in terms of life span...they cant handle the heat and go brittle and then crack...just like our one, not even a year old and its falling to pieces. We got a nice 6boost m/s manifold ready to go on, which i think will do the trick, plus the design looks alot better for flow. Kyle seems to think we should see about a 2-300rpm decrease in lag just from his manifold. And best part, he gives a lifetime warranty on cracks! woot!

I hear about cracking exhaust manifolds a lot, but when I dig deaper I find 99% of the time the whole exhaust system is hanging off the turbo. A rubber hanger or 2 at the rear mufler, that's it. The turbo, the wastegate, the dump pipe, engine pipe, cat (if there is one) etc all hanging off a red hot glowing exhaust manifold. Is it any wonder they crack.

As I have posted many times, I use a vertically solid mount at the bellhousing to block joint and another mount at the gearbox subframe. That way all the exhaust manifold has ot do it hold itself up. I have never cracked an exhaust manifold of any type, thin stainless or not.

:ninja: cheers :)

lol Gary, we have a stainless flex pipe from dump pipe to the short exhaust system(about 2 mtrs worth) we have which goes out infront of the rear p.s wheel, and that short part is supported by three rubber hangers, one off the gearbox subframe, one off the tailshaft loop we made up and the one just near the sil where the exhaust exits. Everywhere upto the stainless flex is supported, only the dump pipe hangs off the turbo. Is that setup really so bad? Does it fall within your 99% category?? Not being rude either.

For the next manifold im gonna put another mount off the engine/gearbox bell housing whichever i can use the easiet to hold the dump pipe from the back of the turbo, and then a bracket from the manfiold to the head somewhere. I think that should be sufficient.

Just a note also, none of the cracks on the manifold were around the runners or in typical stress points.

There is always an exception to the rule, maybe you get to be it on this one.

Although, maybe the solid mount at the gearbox bellhousing to block joint is the trick. On mine, I can unbolt the exhaust manifold from the engine and the turbo, wastegate and exhaust manifold don't move up or down. So the only thing my exhaust manifold does is transport the gas, it doesn't even hold up its own weight.

Plus I have 2 stainless steel rods that go from the exhaust manifold (to head flange) to the turbine flange on the exhaust manifold. So the exhaust manifold gets zero side loading as well as zero up and down. The circuit race G forces are quite severe, so I made sure I avoided that problem as well.

:rofl: cheers :P

    • Well, yeah, the RB26 is definitely that far off the mark. From a pure technology point of view it is closer to the engines of the 60s than it is to the engines of the last 10 years. There is absolutely nothing special about an RB26 that wasn't present in engines going all the way back to the 60s, except probably the four valve head. The bottom end is just bog standard Japanese stuff. The head is nothing special. Celicas in the 70s were the same thing, in 4cyl 2 valve form. The ITBs are nothing special when you consider that the same Celicas had twin Solexes on them, and so had throttle plates in the exact same place. There's no variable valve timing, no variable inlet manifold, which even other RBs had either before the 26 came out or shortly afterward. The ECU is pretty rude and crude. The only things it has going for it are that the physical structure was pretty bloody tough for a mass produced engine, the twin-turbos and ITBs made for a bit of uniqueness against the competition (and even Toyota were ahead on the twin turbs thing, weren't they?) and the electronic controls and measuring devices (ie, AFMs, CAS, etc) were good enough to make it run well. Oh, and it sounds better than almost anything else, ever. The VR38 is absolutely halfway between the RB generation and the current generation, so it definitely has a massive increase in the sophistication of the electronics, allowing for a lot more dynamic optimisation of mapping. Then there's things like metal treatments and other coatings on things, adoption of variable cam stuff, and a bunch of other little improvements that mean it has to be a better thing than the RB26. But I otherwise agree with you that it is approximately the same thing as a 26. But, skip forward another 10 years from that engine and then the things that I mentioned in previous post come out to play. High compression, massively sophisticated computers, direct injection, clever measuring sensors, etc etc. They are the real difference between trying to make big power with a 26 and trying to make big power with a S/B50/54 (or whatever the preferred BMW engine of the week is).
    • Is the RB26 actually that far off the mark? Honestly from where I'm sitting a VR38DETT is not actually that much more advanced than the RB26. Yes, there is a scavenge pump on the VR38, it's smarter in a number of ways but it's not actually jumping out to me as alien technology. Something like a B58 or V35A-FTS on the other hand has so many surprising little design features that add up to be something that just isn't comparable.
