G40 lader limitations.

[Andy]

I burnt the final lot of seals on mine in the same way (pre-standalone) - I was doing 7100rpm at the time on a 65mm pulley, so roughly 13,280rpm charger speed. At least with a standalone you're optimising the amount of heat you can get away from that area - might not be a cure, but it certainly won't hurt.

Anyhow, the real point of this, is don't be a pussy and use a G60-lader instead.

Totally agree with andy...

however - surely if you are already making a bar of boost, there is some serious restriction in the system, get some of this in the engine (i.e. by more efficient throttle body/inlet) rather than backing even more boost up.

Pete I think the issue is that these guys with 1473cc engines are finding that a g40 g-lader on a 65mm pulley is only producing 0.8bar boost at best.  Which in my opinion needs to be solved by putting a bigger blower on (be it a bigger supercharger or a suitable turbo) rather than trying to overwork the 40mm g-lader.

[PeteG40]

still there is 0.8 bar backing up!! !if they want to keep the g40 and get more ponies, its time to look at other avenues me thinks.

Or whack a k04 on it, an eaton or g60 lol.

[hayesey]

yes but it'll make more power with higher pressure in the cylinders.

Cheers guys. Food for thought indeed.

I think G60 might be the best way to go. Well, a turbo is probably the best way but I'm a stubborn git!

I guess if I go with a smaller pulley on the '40 I'll end up with a dead charger that'll be worth f*ck all whereas if I set about the G60 route I can sell my '40 for sensible money as at the moment is fairly freshly full blended.

So what exactly would be involved?

One of these I guess?

Would it mate up with my PSD intercooler without too much fuss?

What about toothies?

Where's the best place to source a G60 lader? Can you still get 'em new?

Thanks again!

Could try JMR for a G60...

Poss G-werks too if Darren's still going.
