Apparently there is a guy in Southern NH who works for BMW that does tunes. I just got a call from my local dyno shop and he would like to tune my car for this kit. I am thinking I will go for the custom tune I have heard great things about his work and my car having the headers may not fit the off the shelf tune from Dinan. In fact Dinan warns about not installing headers with their tune. Will keep you all posted of the progress on the build.

Custom AC line in and working great!! A bit more expensive than I wanted but it is ok. I had it done at Gill's in Manchester they did a fantastic job and with the recharge AC working better than ever!

yeah I will post after work was raining here when I picked it up otherwise I would have posted that last one with photos.

How's your car running? clear up that oil issue?

I am still waiting on brackets to come in so it will be some time before I get it on. Bit the bullet and bought brackets/T9/T15 from Dinan directly. Just working to make the room now, and will probably work to fit the intercooler soon. I think I am going air to water, but still not sure.

Sort of... I'm working with Dinan to confirm/validate what I did. I've found that the oil wasn't actually coming from the oil separator/crank case. Attached is my quest so far to resolve the issue. Today is the second day of driving and so far so good. But I'm trying to confirm with Dinan the purpose of the vacuum line and whether it's safe to remove it.

I did some searching and found no other kit out there that has that line installed except for Dinan's. So I'm thinking what's so special about it? Any thoughts?

how are you draining the oil to the pan?

There was a modified by Dinan dipstick tube provided with the kit. It essentially is a stock dipstick tube with a welded in nipple for the SC oil drain. There is a rubber hose that connects the SC oil drain outlet to the dipstick tube.

Think that could be an issue causing it to not drain fast enough? Clogged, kinked, not straight down etc

also the VF kit says 'Custom crank case ventilation system' they do something

edit: sorry that doesn't answer why vent the vortech. it may be to help it drain...like a gas jug has those vents to help with flow. it may vent to intake to have it drain better. maybe connect the vent of the vortech to the oil catch can.

Last time I cleaned the intake from oil a couple days ago, I specifically checked the drain hose and it looked fine and I would say as straight down as possible. It could be adjusted a bit more (cut shorter), but only slightly, there is no part of the hose that's horizontal.

Come to think of it, since the oil feed is under pressure, there is no way (I think) the gravity drain can keep up with the speed of oil coming in so the oil is probably under pressure inside the SC as well, and if you have another possibility for the oil to escape, it will. Especially considering that the vacuum line is actually under vacuum.

From what I've seen, their kit is very similar to Dinan's. They both provide a custom back plate for the intake manifold and these plates are almost identical between the kits. I did not see VF using the vacuum connection that I'm dealing with now.

Both kits have the oil separator outlet rerouted to the SC intake through an additional PCV valve.

the drain should be under pressure too (sucking from crank case) it wouldn't be a true gravity feed. this is my assumption as there is a suction from the dipstick tube on a stock configuration.

Isn't dipstick submerged in oil?

BTW, I've been looking into air to water aftercooling as well. One option I'm considering is something like this: Long Flow Style cooler. I was thinking to install it inline between the throttle body and the SC outlet pipe. What are you going to do in your setup?

It is submerged when off and the tip of the dipstick is for sure I am not sure it is when running though as alot of oil is elsewhere. Also I don't know if the tip sticks out of the tube or not. I think when the engine is running if you remove the dipstick there is a suction on it.

As for intercooler I was also looking at the long flow style on same site haha. The silicon intake site has good stuff too. Not sure on placement yet for it or the fan. Are you going to raise boost after install? Your kit is supposedly more boost than the vanos kit. I think it is 8 vs 6psi on mine. I may be wrong.

Weeeeeell... that's another issue I'm working on now. The kit is rated for 8psi at redline, the highest I was able to get it to is about 3.5psi at about 5000 RPM if I REALLY step on it. So that's my other quest at the moment to find my missing boost. I already did a preliminary intake leak test and did find a few small leaks, which I'm going to take care of over the weekend, but nothing major. I'm going to test it again in a different way, hopefully will find me some more holes. The blow off valve was leaking, I took it apart, cleaned it, reassembled, it doesn't leak at the valve anymore, but does leak a bit at the adjustment screw. Someone suggested to replace it with a Bosch BOV (part #0 280 142 110) used in Audi, VW, Saab and I'm going to give it a try.

When this is resolved, I think I'll try getting a smaller pulley for even more fun

That is the one the VF kit uses and you can get them really cheap. I thought about going with that one but I found the vortech one Dinan used for really cheap. We shall see how that works out.

Keep in mind if you up the boost you will really need a custom tune to compensate. A little may be ok with the Dinan tune especially if you run rich. See I am worries as I have headers how the Dinan tune will react so I am considering the custom dyno tune.

Nice, pretty much like the Dinan's I have installed.

Just had a call with the Dinan guru Dan, he pointed out that the check valve between the SC and PCV hose was reversed. The flow is supposed to be from PCV hose toward the SC, this way the line provides venting for the SC and the valve does not let the oil to go into the intake. I wasn't sure which way it needs to be installed and followed the pictures the previous owner took of his setup, which apparently wasn't correct. So this one hopefully is now sorted out!

Can you photo the correct way the check valve connects. mine came attached but would be great reference.

Yes, that's correct. My colors are reversed, but the main thing is the pointy end points where the flow goes. Here's mine.

BTW, what is the size of the tee fitting you have there? The only one I could find was 5/8 x 5/8 x 3/8. That 3/8 is still a bit too big, I wish there was a smaller one.

I am not sure on the sizeI will check when I get home.

I also do not plain on using the Dinan back plate. I am going to tap into the pipe and plug the OEM end plate. Run a hose from the pipe to the PCV at the intake. Dinan charges crazy money for something...and other items it is surprising how reasonable their prices are!
