Really?

The 6466 is actually more than both those by double? Or do you mean a lot of people are selling them used for cheap or something? Just confused how the other turbos can be so much cheaper? I am guessing they are all about the same cost to produce.

on pte's website a 6466 is 1909.99, a 6766 is 1199.99 and a 6266 is 999.99 so the 6466 is just normally quite a bit more

i like the 6466 idea lol

although your ef4 is probably pretty nasty

My car is at DB getting the fuel system changed some and setup on E98 so we'll see what kind of power it will make all in. Though my stock ported TB and IM will probably turn into a restriction, maybe the M2 cams too, but, none of that is going to get changed.

The 711 at buschur/773 at MAP my car made was done with a tune setup for E70(that was 5 months old at the tme) too.

Vassil made 745 on a DSM at DB at 35psi, that is why I ask and there are a few DSMs in that 700-750 range without going over 40psi.

That is the only reason I say that, I have heard that the 6466 and 6766 spool damn near the 6266 in a lot of cases though.

Sorry to get off the whole 6466 topic

Maybe I should've made its own thread, didn't think it would generate enough talk.

Anyway, new parts! Trying to solve my whole crank case pressure deal, this should do it. At the track my oil cap came off, not sure if its from the fact it might be a shitty design or just crank case pressure pushing it off, so I didn't want to risk it and bought these. New oil cap (lost mine) and new catch can with 10AN lines and light weight matching bracket on the other side of the bumper.

Here is an example of it installed:

I'll take more pictures this spring when I put it in with my new fuel rail and new injectors.

turbotalon1g · 02-02-2013

If a DSM cap is the same style and fits on your car, you are welcome to try my -10AN oil cap.

I don't think I'd need that. I assume that is to connect to a catch can? My valve cover has 2 ports already.

Yes it would need to be connected to some kind of catch can, well I'm getting rid of it and I didn't know if you wanted more ports.

Here are a few more pics, its part of the front crash beam like Scheides said I believe.

Yea I don't think I will need any more ports, thanks though man

I'll show pictures later, the second bracket is the mirror image, just not a catch can on the other side, weight savings basically.

**scheides** · 02-03-2013

So are there any provisions for providing vacuum to the oil can?

Also how on earth is that 'easy access' for draining? I guess if you have no undertray?

No provisions for vacuum on this. And its just as easy/hard as my current catch can setup, which sucks to drain lol. My current one I have to basically take my bumper off to do. This I think you can pull the undertray and drain, maybe 20 mins of dinking around, not so bad.

**Kracka** · 02-04-2013

Kinda worthless (like most catch-can setups out there) w/o a vacuum source IMHO. Catch-cans generally cause more problems than they solve since most people don't set them up correctly. Having vacuum evacuate the crankcase vapors is much more effective than using the pistons to pump it out. At least this one has large enough lines to not cause additional back pressure. What does it have in the way of internal baffling/packing?

Well my current setup has just one line that is constantly kinked going to my catch can and then to atmosphere. My current one is worthless for sure.

This one doesn't have vacuum and Kozmic designed it and tested in on the dyno and track and said it works great. MAP also said they have installed several and all have had great results.

It's internally a box more or less, no baffling I don't think.

I simply went off recommendations from MAP and several others with big HP builds and all have said it works well.

MAP had hypothesized that my head started leaking previously due to an insufficient catch can setup and said this one should solve my issues.

I agree, having vacuum works very well as you basically suction out all the crap but I think this one will work. Kozmic saw like 10-15whp gains from this on his car that he said is from reduced crank case pressure.

Dunno.

Except there is no engine vacuum when you're under boost.

Dave, even an OEM setup utilizes a basic positive pressure tube to relieve engine blowby when above atmospheric pressure is achieved. If you have more blow-by than that system was designed for, you can lose power.

Suction from the intake pipe. It's not much vacuum unless you have an undersized or clogged air filter, but it's better than forcing it into the atmosphere.

**Murlo26** · 02-06-2013

New gauge pod so I am not blocking my tach/speedo half way now

Plus room for an oil pressure one now too.

It will look like this installed in case you are wondering.
