hotpantslovebug Posted September 22, 2016 Report Share Posted September 22, 2016 I'm running this https://www.amazon.com/AEM-21-2059BF-DryFlow-Air-Filter/dp/B004XH68PM If I remember my math correctly it flows like 930cfm, @22psi on my 2.5 I think it requires something like 830cfm. Realistically you want to run the largest filter you can fit. You don't want your filter causing any restriction. Quote Link to comment Share on other sites More sharing options...

I wouldn't recommend it... The filter I use is the AEM 21-3059DK which is 6.5" in diameter and 9" long. I think that filter is almost the same size as the Jag canister itself. Granted I don't have a pre-turbo pressure sensor, but I wouldn't want to use any smaller of an air filter. 3.5 or 4" MAF with this? Currently going with 3.5 based on what's been recommended. 1300kg would be awesome, I want to say that's abput where Steve is at with his.

Timbo Slice Posted September 22, 2016 Report Share Posted September 22, 2016 Assuming he's on a 4" MAF as that part number pulls a 4" inlet filter, however they make that exact same filter with a 3.5" inlet. I'm currently running a 540i MAF (3.5") with no plans or need to upgrade, so this is probably the direction I will go. Quote Link to comment Share on other sites More sharing options...

That's a massive amount of air holy cow. Have you had it on a dyno? 5 hours ago, lookforjoe said: Air filter calc http://www.gnttype.org/techarea/turbo/airfilter.html Thanks! Got the exhaust bend made today. Only took about an hour and a half for the guy to make it. I like how It came out. 3" mandrel bend to a 2.5" ball at the bottom. Longer 3" run the the previous EST supplied piece. Went to start it and it sounded the exact same. I guess I didn't have the manifold all the way down on the car. As a result the head is leaking like crazy. Tried to give it all another go an it only made a small difference. I think I'll need t free the turbo from the head and then try and torque it all down once more. I hopefully don't need to pull the whole turbo off but if it comes down to it, I can probably get it loose in 45 mins to an hour. The gasket would need to be flatter no?

No spec just pretty tight with a 10" wrench. I think looking back at these pictures I can see the 3 layers are not flat against each other. I think the turbo and the exhaust are pulling on it(which they should a bit) and so what feels tight isn't tight against the head. I hopefully have not ruined my gasket. However, if it isn't sealed then how could I have right? Quote Link to comment Share on other sites More sharing options...
andyb5 Posted September 23, 2016 Report Share Posted September 23, 2016 Torque spec is 18 ft lbs for the manifold studs/nuts. As I said via text, torque from the center out with the turbo removed to make sure the manifold is good and tight/flat to the head Quote Link to comment Share on other sites More sharing options...

As I said via text, torque from the center out with the turbo removed to make sure the manifold is good and tight/flat to the head Working on doing just that! Seem to be able to take apart and maneuver this turbo better then a stock one. I think the up in size and change in position helps accessibility a bit. Going to try and leave the turbo in place so I don't need to drain the coolant. The studs are not fixed in the manifold so I maybe able to fish it out and around the exhaust studs. Though they may still pose a problem. Quote Link to comment Share on other sites More sharing options...
gdog Posted September 23, 2016 Report Share Posted September 23, 2016 Did you ck the flatness of the head and ex manifold mating surfaces before assembly? Assuming so, but thought I'd ask.. Hope you figure it out.. Quote Link to comment Share on other sites More sharing options...
