      With a serp belt you should not cause any damage to the charger without a high flow diverter or bov but I have noticed that partial throttle acceleration feels better. whenever that dv is closed and the throttle body is closed or only partially open the supercharger is acting like a mechanical brake. It robs you of power when you are not in boost, which is most of the time driving on the street.

      Also, diverter valves designed for turbos have pretty high spring rates. They tend to stay closed until a high vacuum is reached. This is not optimum for a centri-supercharger. The most efficient way is to run a dv or bov that is designed to work with superchargers. These units will be open at all times except when vaccum drops to near 0. My bov is open while cruising and only closes at half throttle or more. its a little loud but you can feel the difference.

      To sum up all that ^ A bov or dv designed for SC's will be easier on the SC, engine, and result is less heat generated.
      There is a vid of my bov here:

      Iw as cogged with a Mondo diverter valve. 2" 60 mm in/out. but the BOV is a good option too.

      Finally running in Lug and waiting for a final tune. Seems to run great once its warmed up but the idle is surging during warmup.
      It seems to be caused by the IAC but still trying to figure out how to adjust those settings...

      but will cause problems running the valve post MAF. go with a hard spring. otherwise the car will run to rich in idle and after shifting.
      normaly you need to recycle it to the intake. or do you run free squirt?

      It is tuned in pretty well now. There is no maf with lugtronic. You do not want to run a higher spring with a charger and especially with cogs unless you want to risk going through charger seals and belts.

      why do u say charger seals?

      Well I would assume that if the throttle plate is closed at idle or decel, there would be some compressor surge of the bov spring rate was too high... causeing a lot of boost to surge back and ruin bearings, oil seals... with a non cogged setup, the belt can actually slip during these conditions so the stress isnt all on the charger....

      i can see bearings, but seals are rubber and didnt think how these would be "ruined" Maybe Im confused as to what you and Carlicious / Napkin are referring to. If youre using a BOV, why would this create a surge. Im running a Mondo valve ( Diaphram ) from Vortech and although its a Diverter, it can be run atmospheric.

      Hey guys!

      I have installed a VF-Engineering 10-PSI kit with internal oil (No oil from engine)

      My problem is that when for example put the car in fifth and drive at around 1800 rpms, it will start "coughing" and running bad - If I then accelerate, all hell breaks loose in the tachometer, and I have to clutch to stop the madness. A downshift to fourth will do the trick.

      What may this be caused by?

      Drove a while today - The engine "cough" / unstabilities happen periodically and seems to happen under 3000 rpms when i use the throttle. Almost as if there insufficient air or fuel

      Simple check;
      See if you have any air leaks, and that any silcone couples aren't compressing on themselves.

      My friend had a long silicone coupler on his boosted car, and under hard throttle it would collapse and the car would struggle.
      Otherwise, make sure you're getting fuel. If you've got an old FPR it may be toast.

      Also, make sure your MAF is facing the right way.

      FPR is almost new, and MAF is the right way.

      I dont think the MAF is ruined, because I can drive perfectly for 15 minutes, but then there is 15 seconds to a minute of the engine having spasms when I accelerate. I will run a diagnosis tomorrow.

      I appreciate any further input :-/

      Just a thought - As you all know, oil is NO good for the air mass sensor. The current setup is a pipe that goes from the crankcase breather, into the lower intake pipe. This means small amounts of oil will go through there, right? And JUST unterneath my lower intake pipe, is the air mass sensor - That might be what is causing my cough?

      Any thoughts on this?


      Also, I did some further investigation. The problems comes about every 10-15 minutes. It seems like tha car goes into "Emergency mode", because if I release the clutch and floor the pedal I dont get above 3000 rpm. If I floor the pedal with the clutch enganged, the car starts shaking like a mechanical bull. All I have to do to "reset" this is to release the clutch, let the RPM settle at idle, and engage the clutch again - Then the engine runs like a purring kitten for another period of time.

      A friend of mine suggests ignition problems - I am using OEM leads and NEW Bosch FC3S plugs - I was recommended to swap them for NGK BKR7E plugs, and I also think about investing in high performance 10mm leads.

      Thoughts? I need all the help I can get

      Case update!

      00533 - Idle Speed Regulation
      10-10 - Adaptation Limit Not Reached

      This is a fault I am reading from my car.. it was intermittent, which means "old". But it was NOT there last time, so I think this is the thing causing issues for me. How do I solve it?
