Perrin vs Radium AOS

[Andy_Mac]

After people's thoughts on either option. Both are similarly overpriced but can live with that, just can't de ide on what one.

Both have coolant connections, both are essentially joining the head and crankcase breathers together in one catch can, and both drain the oil back to the crankcase port in slightly. Different ways.

Only real difference I can come up with is that the Radium one completely eliminates the PCV where the Perrin keeps it, but changes the setup to include the crankcase and heads which may be quite useful for low load driving where vacuum at the turbo inlet is not strong enough to pull the whole way through the CC, the heads and crankcase.

The big issue with the Perrin kit is how crappy the plastic connectors are that screw into the can and how insistent they are on weeping oil. Everyone I know who has one is living with the constant film of oil around those connections.

 

I have no experience with the Radium kit but their fuel systems parts are high quality and well thought-out.

 

The Crawford kit works fine for me, though again it's overpriced. If I'd had more patience or time for bracketeering I'd have DIY'd with this: http://www.aircraftspruce.com/catalog/eppages/oilseparator05-12369.php

There is the option for the Perrin to come with metal fittings instead, but adds an extra $90 to the cost. Quality shortfallings seem to be a fairly common thing with Perrin so maybe the Radium is the way to go.

 

Yea their fuel stuff looks pretty good too, actually came across the Radium AOS whilst looking into their top feed conversion kit.

I carry both, shoot us a PM when you decide which one you want, can give you better pricing.

I have a perrin with no issues. I put rtv black on the bottom as per instructions so no oil seeps and I also used teflon tape for the fittings so they don't weep either.

Just came across this one to add a 3rd option to the mix.

Used to run a dual Saikou Michi can setup, mine was not a true AOS tho.

Nicely put together, high-quality, custom to your needs.

Almost got those a while back but kinda like the drain back setup of an AOS, and i'm a bit too inpatient for the 12ish weeks wait time

I run an IAG AOS and have been for 26k miles with zero issues.

+1 for my IAG set up as well. Race version no PCV, no issues.

Another +1 for IAG. I have there street version. Install was easy, everything works great.
