just make the hole where cubes said.

Mine has the pin hole directly opposite the nipple that feeds the wastegate actuator, so smack in the middle.

here's a pic

lol...as you can tell, i'm quite keen to see if this fixes the lag :)

It may not be the contoller that is causing the "lag". Lag between gears is normally because of long intercooler pipes. When you change gears the air gets released from the system, and has to travel all the way along the intake system again. This cannot happen instantly, so you may feel some lag. This is one of the reasons why the V-mount intercooler systems are so popular in Japan.

I've got a blitz LM front mount...pipes are shorter than all the hybrid/trust/hks etc kits....

Lag caused by a boost controller not releasing the pressure between the boostcontroller and actuator cannot be mistaken.

As you grab the next gear boost comes on really really slowly and smoothly. It sucks. :no:

Yes front mount systems add some lag to the setup but i feel that it is more throttle response rather than on gear changes at WOT that it effects. A simple test is just remove the boost controller and put a tee piece back in or a line straight from the ic piping to the actuator and you will see that the boost response is much better on changes-basically instantanious - hence the controller is causing the wastegate to stay open too long...

I brought one recently and it doesn't have the little hole in it. I don't get that lag everyone is talking about, I don't have an FMIC though with long piping. It does seem to drop of boost significantly (3psi or more) at high RPM though, but I assume this is something else, not the Turbotech MBC.

Anyway I've ordered the Apexi Boost controlle for the Power FC so I will give that a go.

that's pretty normal... 2nd of feb was a friday, so the money wouldn't have hit the account until about 6th or 7th . Gotta make it then, and then send it out, so probably not enough time to receive by today. Don't worry you'll probably get it mid-late next week some time. He's just a one-man-band.

well all is well, its sweet as to drive boost hits hard much harder than factory settup.

but the only downfall is that it looses boost up top. i have it set at 14 pound atm. and when it drops off up in the high revs it goes to 11-12 pound... so not too bad it still pulls.

definatly an improvement!!!!

next thing i will buy is an EBC but untill then im happy with this

even tho i had to drill the hole my self... grrr....

yes, drill the hole.

cuz if you dont it keeps your wastegate open when you change gears and it lags like a mo-fo.

so you need to drill the hole to let teh extra pressure in the line between the actuator and the BC out.

my 1.1mm hole works just fine, so id say anything around that size would be good :D

      My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
