Does anyone know if there are any direct fit, (clips and o-rings, slip joint) non silencer equipped charge pipes for both the turbo exit to intercooler AND the intercooler to up pipe to manifold WITHOUT resonators preferably in aluminum? I've been busy at work, like REALLY busy so free fab time is limited and has been for almost three years now. Going to redo a bit of plumbing on the post-compressor side of the equation while switching to a different AEM water/methanol strategy. If isstay is still around I'd love to chat on that AMG 10 blade exducer and larger compressor wheel, eventually I'll have to rebuild my turbo and I still cannot leave well enough alone? Can you get these parts? I have not found a source in USA and LOVE the sound of the 10 blade exducer s, have kept the one on my 6.0 Ford work truck going for many years and a rebuild and another partial rebuild, NOTHING sounds as close to a jet turbine as an even 10 blade exducer and preferably an even count compressor. Car is worth nothing now at 213,000 miles here so I just keep adding power.

Also current torque at 478 ft/lbs, which is fine but definitely wouldn't mind carrying that or more to higher rpm which is where it is more power. Where do I hit defined failure point of trans. I do not often use full power, like a few times a year and change trans oil every 50k miles or so but have never seen debris or even significant darkening of fluid. Commute is 100 miles daily.

The water/meth thing I want to switch to charge temp triggering ONLY instead of boost combined with "at will" use via manual control. The reason is often in Texas summers 104-112F is ambient temp so hitting 50C power reduction can happen often with my mapping where I left that safety (for the motor) protection alone. I have a slightly larger intercooler but have also been considering a water to air charge cooler as they work much better on everything I've tried them on...

Enough for now. Back to ordering disks and pads and sensors and normal wear items. SBC cannot even with Star or iCarSoft be convinced my severely worn rotors -6.5-7.1mm front and -4mm rear are OK. Time to fix this for the next 200k. Pretty ones in shopping cart, cast with holes, not drilled.

PM or email me pics and pricing, with shipping across pond. Micahshoemaker at hotmail dot com. I'm especially interested in a turbo out pipe without silencer and an intercooler to up pipe without resonator. The ten blade AMG turbo though, that is fascinating to me!

I wouldn't kick a bigger charge cooler out of bed, no matter their efficiency when air temp at intake duct is 118F they can only do so much

Well last night was quite the score for eBay accidental shopping. Found a complete exhaust manifold with turbo plus outlet silencer (what I was looking for to make a non silenced full flow replacement) plus charge cooler piping from both sides for $101 buy-it now. Couldn’t resist. Had to have lol. So ordered some round stock to make block off plates, some AEM water/meth injectors and nozzles. Of, comes with all electronics too. Score lol

Well...considering paint color options for the intake now, very unusual for me. How does a green color sound, possibly black krickle though as I’ve got to order a batch of that anyway for another project of the DIY sort? I’m not polishing the stupid thing but this V3 plumbing set I think needs a little cooler. Next hose replacement I’ll be doing a combo or red (hot) and blue (cooled) SAMCO like on my other rides so green might be a bit too obnoxious? Valve cover will have to come off before 300k miles (222k now) for gaskets and such, probably paint it at same time. Loved my gold Kringle NSX valve covers....dunno, any input, including, WTF is wrong with you, leave it alone....is appreciated lol

If I make a V4 manifold I’m only using part of the stock manifold, water to air charge cooler will make up most of plenum section and all port runners will be tipped with appropriate radiused stacks.

So yes, the V3/4 version of the intake manifold is very much like the truck manifold already on the car. I’m just amazed my first attempt at TIG welding plate to cast aluminum in twenty years went so well, hacksaw cut rough shape, zero filler material or rod used, water tight on test bench. More to come, doing something a bit counter intuitive with the angles of the water/methanol nozzles, you’ll see shortly after my raw material arrives. Having a lathe and CNC at work is so freaking awesome!

weird, the pictures I uploaded are not showing up...can always link to them if needed...

Stock OM648 intercooler discharge pipe with silencer, soon to look different

Stock OM648 intercooler discharge pipe with silencer, soon to look different

Stock OM648 intercooler discharge pipe with silencer, soon to look different

that was fast...by tomorrow or next week the intake silencer on this pipe should be gone for good!

A6481400087 is the part number for the turbo discharge pipe in aluminum for the OM648, just got one coming from a breaker in Ireland! $55 shipped! Finally a modification worthy part!

Just hoping in aluminum it’s and easy cut/weld while retaining stock clip type boost pipe connectors to charge pipe to cooler. If I need to shorten, none side and replace silencer cone on other no big deal.

As long as ID is correct on turbo end and output side, it’s just a little TIG time, if I get my saw cuts close to right one filler rod or less I hope! Then any internal roughness will be addressed with porting tools....maybe going onto a new charge cooler, getting VERY tempted to go max, some modifications required air to air on this one with these new parts plus the water methanol to get a V3/4/5 set of results.

So EGT question for the pros. On racing motorcycle builds for land speed I put both wideband and EGT probes pre turbo for max speed and data resolution at lower rpms. What is considered THE ideal location for an EGT probe. I’m thinking near entry to turbocharger as it should show a nice consistent blend of all six cylinders EGT and allow me to never exceed 1180x1200F, though on race bikes I commonly run 1550F if supercharged or nitrous, but definitely not into a nice Garrett Turbocharger.

Btw, I have seen that aluminum compressor “oil return”/silencer in a form closer to exact replacement part but could not find again. I try to save all part numbers for easier searching. That said, my master list was on a tablet destroyed by a customer by accident so I’m rebuilding it slowly. If anyone has the Saloon differential part number it’s like 7% taller final drive gearing, I need to get another of those too.

Yes, the estate or wagon has the taller differential. It’s only a little like 7% but I got anther 7% or so out of my dirt road tires, it all adds up. If it can make boost at basement rpms, I see little advantages in spinning crank faster since 98% of my driving is a hundred mile daily highway commute. Even my winter fuel economy is pretty damn good lately, granted it’s texas so winter is not really like WINTER for most of you folks.

That looks like both a metal shard filter (pump failure bits) and indeed a flow restriction. Bought tuikku’s intercooer and large volume pump yesterday....the charge cooler will not longer restrict airflow for me. I’m gonna need a solid 12 hour day on lift to mount these next round of mods and service transmission again (second time in 222k miles) and final drive fluid, first time in 222k miles really.

Issatay and tuikku, your thoughts on this bit pictured above? If it offers only minimal restriction while protecting injectors I’ll keep em’ in place. Injectors are crazy money.

Almost exactly where I was thinking. Cool. I’m a little scared of running over 1200F. My Ford 6.0 stage one reflash ate its exducer side alive going up the Raton Pass pulling a trailer on IH25 at an indicated 1220F and that EGT was at turbo exit where all the Ford crowd says to mount, they are wrong obviously but that was a expensive lesson. No crazy tune on it, no EGR and only one of 5 steps hotter than stock on EDGE programmer. Ruined a really nice 10 blade exducer and shaft.
