JHMotorsports Goodies Installed -- 4.2FSI

For anyone interested in some minor improvements, JHM has some nice products that will carry over to the Touareg.

Here's the lightweight crank pulley that they offer, installed on my Touareg...



A pretty nice weight reduction from the stock pulley. About 5lbs of rotational mass, GONE!!!

I also went with their intake manifold spacers. As if daily driving doesn't transfer enough heat from the block to the manifold, try living in Arizona!!!

A couple quick shots during the install...

While I had the manifold off, I just HAD to check out the carbon build up that the Audi/VW FSI motors are notorious for. Something to think about, I'm a lil over 60k miles. I ran (2) cans of CRC Intake Valve Cleaner about a month ago. And I still have this much build-up...




It took me about 3 hours and 4-5 cans of brake cleaner to clean them all off. It's amazing how slimy and gooey the stuff is. Once you let the cleaner soak in, the carbon deposits do come off easy.

So for anyone looking to tackle the project, plan for a lil over an hour to remove the manifold, AT LEAST 2-3 hours for the cleaning (depending on how picky you are), and another hour to put everything back together.

NOTE: If you do the spacers, there are only two things you will need to "customize." One... undo all of the clamps that hold down the hard fuel lines to the block. You will need the extra play to wiggle the lines back on to the HPFPs and the distribution block. Two... there are two screws that secure the oil bypass to the block. You will not be able to use these bolts. But you can ziptie the holes together, if you think you need the extra stability.

Once you get in there, you will know what I mean...

Interesting mods and cool project. So what are the benefits of these parts, especially the spacers?

The spacers will limit the amount of heat transfer from the block to the manifold. So in theory, a cooler intake charge will be entering the combustion chamber.

Here's what JHM has...

Somehow... I've picked up another 50-60 miles per tank! Even with the AC running all the time. It is 120* out... ?

Could it be the spacers...?

Could it be the manual carbon cleaning...?

Who knows... but I'll take it!!!

50-60 miles per tank, wow!

What is the part number for the pulley, is it the one with S4 or S5?

That is certainly a great benefit! So tell us more... Any noticeable difference from the pulley? Does the engine seem to rev easier? Any engine/sound difference from the manifold spacers?

It seems like the manifold spacer take longer time to install comparing to the pulleu?

The parts for the V8 FSI S5 were what I ordered.

As far as the pulley, there is a lil more of a snappy response, more noticeable with the AC off. When I did lightweight pulleys on my Nissans in the past, chirping the tires were easy, even goin into 2nd. But don't expect chirping in the Touareg... ?

As far as sound from the spacers, I'd have to say no. The gutting of my intake boxes were what affected that the most.

As far as the installation processes, the manifold by far, is more time consuming. The pulley really is as easy as...

Move tensioner to allow belt removal
Remove belt
Unscrew bolts holding pulley on
Transfer guide pin from OEM to JHM
Bolt JHM pulley on
Reinstall belt

Should be under an hour worth of work...
