If you want a seriously noisy G60, sell it and buy mine! Look for the G60 200+BHP in the cars for sale area.

That is one big intake plenum! That must be 4 inches across!

Regarding the Eyebrow spoiler, in case people are still interested to know, it is a Mattig item, bought in Germany. I know the former owner as he is the other half of Radicool, famously known for the cobalt blue MK1 golf.

You need the "Theile Small" parameters for the specific bass driver. They will tell you about the internal volume of the enclusure, the length and diameter of the port etc. Some units don't need a port, it all has to do with the deisgn of the voice coil, the materials that make up the cone etc. When deisigned the enclosure there are some basic rules, ported or not. Try to limit the number of parallel sides, these cause internal reflections will tend to make the bass notes 'hang'. Make the MDF as thick as you dare and reinforce the long sides with internal bracing (you can use a pice of MDF with large holes cut into it screwed across the enclosure). Use glue as well as screws, the enclosure must be airtight (except fot the port).

Brown is the way forward, I would love a respray in Porsche Rosewood Metallic

Yuk that looks terrible! A 15" wheel with a 195/50 is smaller than a 17" with a 40 series tyre, contrary to what G60 Jet was saying. If you fit 17s you have to lower it more to make the spoiler as close to the ground as it was on 15"s. You will get some fouling on the inside of the front arches whilst parking, just ignore it. The rear arches will need to be trimed a little at the front edge as there is usually a part of the flange which protrudes a bit and as the car gets lower, the wheel moves forward in the arch.

I think you have to login to see them, they are right at the top under the list of modifications.

The larger the intercooler the less pressure dop it will create. Don't get the term "pressure drop" confused with a "drop in pressure". If you pass a give amount of air into a large intercooler it will have resistance due to the larger surface area and the fact that he air will be moving at a lower velocity. This is the same principal as large bore exhausts. The bigger the tube the lower the velocity and the lower the resistance ("pressure drop"). The only drop in air pressure you will get would be caused by a leak.

The black box next to the header tank is for the two stage cooling fan, the blue pipe is for a rather hastily installed boost pressure guage. The car is an almost daily driver, but once the engine has been made clean it isn't hard to keep it like it. I use "kitchen power" cleaner on the gearbox, engine etc work it with a paint brush and hose it off. In the winter I cover it all in WD40 or silicone spray and wash it all off again in the spring. Autosol and elbow-grease occasionally.

Use a motor cycle radiator or air conditioning radiator and a 12volt marine bilge pump. The pumps are as little as £12 from a chandlery and the rad can come from a scrapper. There is no loss of boost pressure with either system, unless of course it has a leak. There is a difference in system resistance ("pressure drop" is a term used to describe back pressure) and the less resistance you have the more easy it is to pump the air in.

The bigger the filter area, the less resistance it will offer to the air passing through it. Assuming the filter media is up to the job, the filter with the largest surface area will be the least restrictive. Conical filters work prefectly well if properly and regularly cleaned and oiled. They will make the charger noise more noticable because there is obviously nothing encasing it. Take a look at my own intake in the members gallery. It uses a 3" intake and a huge JR cone filter.

It's not the spoiler I'd be worried about, they just wear away! Next time you have it up on a jack, take a look at the driveshaft on the driver's side. I reckon you will find a load of underseal on it and a corresponding rusty dent in the chassis rail above it. My car is on 15"s and doesn't sit quite that low but I still get marks on the axle.

I really don't know how much power it makes, I have only dyno tested it once, before the CAt was removed and the Intercooler was added. Since then the Supersprint exhaust has gone on and the Charger has been flowed a bit more. I must get it remapped one day as it it still using the same mapping as it was when it just had a 68mm pulley. AMD next year maybe for a Rolling Road day?

I have just added a few pictures of my motor, and some of my intercooler, for those that are interested.

Samco are terrible to get hold of. I waited nearly 7 weeks for on of the elbows I used and it was only a standard 90degree 2.5" in blue! The rest I did all right with, £23 for the intercooler, fabrication work, free, aluminium pipes rolled and swaged at work for free, spigot thing for the air mass sensor, free, Samcos.....£120!!!
