Less than 2 months later 50 sets of these are almost gone. There were some outright sales but most of which went out complimentary with new turbo purchases (now the standard). Another 50 sets coming in this weekend from machining.

Another 50+ sets have been received, welded, anodized, and ready to ship. Just an FYI to anyone who maybe wanting a set.

Thanks,
Rob

Hi Rob,

Getting these fitted now, along with newer turbos, however the front new rb oil drain pipe doesn't seem to clear evenly and tends to have a very severe bend in (if pushed to fit correctly) which would possibly have an negative effect...

quick pic of old pipe in situ with waterpump hose too (rhd car).



Are there any tips for installing?

thanks
Tin

Have sent about 70 sets out as of now, have not heard of issue. Maybe send and email over or post a picture of what you mean here if that's your preference.

Thanks,
Rob

Ive installed two and they do have a bend to them, it seems like the hose is a little bit too long. So trimming it would help with the bends. I've installed one on a pure stage 2 and another for an OEM turbo swap and so far no issues.

Thanks for the feedback. Yeah we did get a call on one of the first sets saying they thought the hose was a bit too short, and adding .5" would've made them feel more comfortable (although what was provided still "worked"). So I arbitrarily began adding .5" to the hose to avoid any future discomforts, although it seems it went the other way lol. I guess to summarize the hose if anything too long, and it should be very close to straight when installed. Cutting the hose to length maybe required if you can't get it to push up the adapter high enough.

Running low on current batch, but we've some sets left. We've gone through several batches now and a new batch of 80 sets coming soon.

Hi Rob, just a quick question. As the drains are bigger, oil will flow faster out of the turbo. Does this mean that the feed flow will be increased too? What controls this? Oil pump?

Many thanks

You are correct that the turbochargers get their oiling from the engines oil pump and pressure system. They are a direct feed just as the engines main/rod/cam bearings etc. The turbos have restriction orifices built into them (along with tight clearances in the bearing systems) for the pressurized oil to keep the metallic items "afloat" on a thin pressurized layer of oil while in use. As long as this oil layer or barrier is maintained the turbo components will be protected from wear.

This is the exact same premise of the engine components, just the turbos are spinning around 25x more RPM at high loads. Anyway once the oil passes through it simply drains while constantly being replenished by new pressurized source oil, again just like the engine drains back into the pan. The turbo oil drains themselves just help ensure the oil makes it there as quickly and easily as possible (i.e. from a kink or being undersized), as if they do not the oil will puddle in the lines and fill quicker than the cartridge outlet lines can evacuate. This can lead to filling of the cartridge and literally oil being forced out the seals (despite them being fine).

In short it is always best to have a drain that is most up to the challenge to get the oil back into the pan ASAP and way from the turbo CHRA once it passes through to avoid any chance of CHRA oil filling post the pressurization area of the cartridge.

Thanks,
Rob

Thanks for your quick and very detailed reply Rob. I'll be ordering the drains soon. Do you usually have them in stock?

Regards

Duarte

We have another batch going to anodizing this week, so they are in stock in bare aluminum at this moment. With anodizing completed they'll be a few days out yet, probably shipping Saturday at earliest but more likely Next Monday/Tuesday.

For the custom build (ie. non stock frame) guys we also have these adapters available in almost every configuration imaginable such as -10AN front drains/plugged rear drains/single or dual oil feeds/-6AN coolant adapters/etc.

You 100% do not need to remove the engine mount.

Done it about 10 times.

You need a long 1/4 extension bar to torque the bolt closet to the block, just use the extension bar and socket to start the bolt the get the ratchet once it's nearly seated and just a 10mm open spanner to tighten the other bolt.
Bottom is accessible and easily fitted.

Just use a different hose clamp the squash ones provided were to difficult to fit.

Should have no problem besides initially making sure the gasket is lined up with the bolt holes.

For the upper (turbo side) drain fitting bolts we recommend tightening with the closed side of a 10mm wrench to a tightness similar to torque spec.

For the rear line the engine mount should be much in the way to do an easy installation, but for the front line the mount will certainly not be in the way.

The spring clamps that come with these drains are actually OEM spec style clamps used across many platforms- they work well as is why we supply them.

Some tailoring of the drain hose maybe at times necessary to fit to the installers liking- but they should be close as is.
