VR6 Tips and tricks/info

Post by Yakuza Racer »

so went searching, i know you can use another MAF instead of the vr6 maf, but came across this:

"Anyone heard of/tried this? Basically just involves filling up both male and female MAF plug with dialectric grease (from Maplins etc) and apparently smooths idle and overall performance. Been reading up on it on MKIVs & Briskoda and the general concensus is that it's well worth doing- especially as it only costs a couple of quid.

Apparently the grease totally stops any arcing etc within the plug, which could normally occur with just air present instead. The electrical interference/arcing etc could possibly be almost non-existant, but as the MAF is so sensitive, it could affect it. Have ordered some and will give it a go on the vRS.

Originally thought that it was one of those cheap placebo type mods, but so many people have had success with it, it's gotta be worth a go. "

now to the kid in me i wanna try it, but the man in me says " do not **** with it"

so could this very well be a positive mod? yes it will be

AH found it!

http://www.gruvenparts.com/website/diys ... 20Info.htm

but looking at the MAF's the vr6 one is noticeably larger... so it begs the question, will it work the same as the vr6 one?

How it works

The VGR manifold can be fitted to both 2.8 and 2.9 litre engines. Eventhough the VGI achieves similar aims to Audi’s switching inlet manifold, the operating principle is different.

In the Audi engine, a long, narrow inlet tract achieves high torque at low revs and maximum power is achieved using a short, wide inlet tract. For the engine to feed through the appropriate channels, inlet manifolds are switched using six individual vacuum operated flaps at 4000 RPM. In both stages, the technology is based purely on tuned oscillating-flow inlet manifolds, with the necessary switching.

In contrast, two diverse technologies are applied in the VGI. It is designed so that at low engine speeds, resonance is used to improve cylinder-charging efficiency. At higher RPM, oscillation-tuned, individual, broad tracts are used. Switching from one to the other is achieved by single flap, also vacuum operated at 4000 RPM.

The tuned inlet tract operates by the low pressure caused between the throttle valve and the inlet valve, by suction of the descending piston. Through inertia of the air in the tract, the airflow tends to keep moving towards the inlet, even after its closed, causing a slight over-pressure when the inlet valve next opens. This ensures high charge efficiency even during early stages of the induction stroke. Further during the same stroke, inlet pressure falls followed by high pressure but not before the inlet valve closes.

In order to achieve optimal control of the oscillation and reflection of the column of air in the inlet tract, it needs to be closely co-ordinated with valve timing, but this is not possible due to variation in the engine speed. Even at mid-range-rpm, the valve opening and they are out of synch. The second pressure wave arrives much too early before the inlet valve closes and a backflow reduces fuel efficiency.

Now to achieve high torque under these conditions, resonance-fuel is utilized. This is achieved by closing the connection flap between a small resonance chambers immediately before short inlet tracts above the inlet valves. These transforms the 6-cylinder engine into effectively two 3-cylinder engines with uniform firing times, which do not have overlapping inlet strokes. A resonance pulse of up to 6psi (0.4bar) above atmospheric is achieved, leading to remarkable fuel efficiency and torque increases.

On the road

The effect of the manifold is immediately apparent – you won’t need any test equipment! A new urge is sensed almost right from the idle. There is markedly better acceleration up to 4,000rpm, followed by a strong surge to the redline. The switchover of the flap is almost undetectable from inside the car.

The new low to mid-range power is particularly useful in the higher gears. The 50-70 sprints in fourth is reduced by almost a second! Fuel consumption is also improved, as higher revs don’t need to be used as much
