|i thought for the 16v, there was no need to adjust it, and if so (only on the stock vw unit), only like 3 clicks, just like the 8v? confirmation anyone? |
ok. lets get this cleared up now. how many clicks (if any) for the bmw unit on a 16v. i know on a stock vw unit, 3 clicks work, especially for the 8v. how many clicks for the 16v. the same 3 clicks...more? ideas???
As per Digiracer in the 8v FAQ:
... 16 Valve Digifant II owners, this is a must do mod IMHO. Near stock or heavily moddified, 16Valve engines can really take advantage of this. Whether you know it or not, your 16 Valve has athsma & this is the cure.
The Point: Significant increases in Horsepower & Torque throughout the entire rev range. I'll have some dyno numbers soon. If you're serious about big horsepower and you've done everything else (cam, intake, chip, exhaust) this is the next step. If you didn't catch that, this should be done last.
1. Airflow Meter: (AFM) found on the 85-88 BMW 535i (most common), 635i, & 735i. It's the K Series Engine, a 3.5 Liter SOHC Inline 6.
New AFMs for these cars are expensive, as high as $450+
Used ones are very cheap from $40-$100 (I only paid $60, shipped to my door) & they can be found @ http://www.car-part.com/
Search for 1987 BMW 535i under Airflow Meter
Mine is from a 1987 BMW 535i it's a Bosch Unit.
The part # is: 0280 203 027
Note: Do not use the BMW AFMS found on the 325i, 328e, 525i, 528e etc. these units are the same size as our stock/OEM units. (they'll work fine, they just won't give you anymore power)
Note: Your engine is not going to pull the vacuum of a 3.5 liter 6cyl. Therefor you need to reduce the spring tension to allow your engine to idle properly. (with my 2.0L ABA/1.8 head I found reducing tension 8 clicks to work best) If you're using a 1.8L I assume you'd need to reduce it more.
I'm at about 7 clicks right now. I find that if under 1500 rpm in any gear, if I punch it, there is not enough intake to pull the flapper open. The car bogs.
I will try to play with the settings some more.
