Experimental G60 compressor.

A friend from gti16.com is preparing an experimental G60 compressor.

Here are some pics, just to have more opinions. Another granade?





With the stock intake 39 straws went in, with the new 76; almost double the size. Simple engineering.........









Lets see how it works on the car, and how long it lasts

greetings from Spain!

 

You can tell the quality of engineering by measuring stuff with straws......

 

Engineer come from the latin word "genium", in other words "genius".

You dont need expensive flow mesurements if you have a few straws.

Keep it simple, Its just a experiment.

cheers

 

I never truly understood how G-laders work , must go googling now....

 

is that another inlet or outlet ?

 

nice welding......

 

2 inlets, one for each half of the compressor.

In the same way you have bigger inlets valves in the head to get better breathing, the stock intake is the restrictive part of the charger.

 

I've welded a fair bit of cast aluminium. Your friend should have cleaned the casting 10 times more than he has. soak in solvents, heat it up, Bead blast then repeat twice
IMO vibration will cause his welds to fail.

Good intentions poorly excecuted

 

That's some quality welding! Was your mate trained at Rover???

 

looks like you have some big seagulls round your area, looking at the bird cack all over your welding lol

thing is its better than my welding lol

 

rover train people ???

 

You are focusing on the quality of the weld and the straw thing.

Its not a professional job at all, just an experiment to see if a G-lader can benefit from a bigger inlet, and the double admision idea. If it works the 2.0 version will be neat and tidy.

Lets see how much it blows with a 68mm pulley, any one want to guess?

 

Do you think there will be enough strength left in the outlet for the bearing? If I remember correctly, there were two outlet types on G60 chargers - one with four ports and one with six. The four port outlets don't have as much strength (so I've read.) I think that a lot of G60 tuners refrain from removing too much material around the outlet, becuase of the strength required for the bearing. I'm no G60 expert though!

Also, did you decide not to delete the boost retun pipe to enable twin inlets, rather than adding another? (I know that some people don't like deleting it because of the oil vapour lubricating the internals etc.) Just curious.

 

The rs2 porting leaves only 3 suports.

that's a G40 charger....

 

Never been a fan of the 3 support mod, these things have a hard enough time surviving as it is without removing a 1/2 of the bearing supports and then some..

Fair play to him for having a go though, will be interesting to see how it holds up.

 

If there is going to be another version he could make the additional inlets radiused to give a velocity stack effect.

The porting is nicely done, unfotunately removing 3-legs from the outlet severly reduce the reliability of the charger. Non of the big German rebuilders do this anymore. It is not uncommon that these chargers failed after a couple of thousand miles on the autobahn.
It is just like buying a 6 spoke rim, and remove 3 spokes for improved cooling to the brakes. Would you do that?

As for the extra inlet, I doubt it would help, as it is position totally wrong for the scroll to be able to use the extra air. It would be better do do something in the lines of the Jabba R1-85 charger

 

Frode, what's a Jabba R1-85?

 

It is basicly a R1 with the inlets cut off, and a 85mm alloy pipe welded on to replace it. It looks really OEM. There's a company in the USA that did a 95mm version too
