more supercharger talk

[truckinwagen]

yeah, it feels good to have it up and running properly again.

I backed the max fuel screw out quite a bit, so it just barley smokes at WOT with no boost.

the G60 alt pulley just arrived, so I can get on with installing the new alt and smaller charger pulley with the six rib belt.

hopefully I can score a garage to work in for an afternoon to install it.

[truckinwagen]

the stock charger oil feed line just came in today, so it looks like tomorrow will be a big install day.

hopefully I will have all this stuff figured out by tomorrow night so I can drive out to Alyeska on saturday to go snowboarding with some old friends.

-Owen

[truckinwagen]

well, I got the new alternator installed today.



I had to ditch the lower idler gear, so the water pump does not contact the belt much, but it seems to spin it just fine all the same.


I took it for a test drive, and it topped out at about 18PSI, when it started making very unhappy noises.
I limped home, with it sounding like this:


I pulled it apart, expecting the worst, and got it.
the little timing belt in the charger had broken, and it was a new one from GAP, less than 100 miles on it.


the displacer looked no better than the belt.





looks like it is time for a new charger...

[truckinwagen]

not sure, I am contemplating an eaton.

I can get an M62 for $150, which is better than the cheapest G60 I can find is($250)

the eaton is not very efficient, and does not like to boost past 10PSI, but would be better suited for twincharging.
although having to buy a new charger takes a big bite out of the non-existent turbo budget.

I might just get a shorter serp belt and run it N/A until the fall, when I have some cash.

-Owen

[RadoTD]

Ahh! That sucks

What about an M90 instead? Do they just become a heat pump over 10psi as well?

If you've still got that bearing girdle, I can help donate a few $ to your car fund.. I'll pm you

[truckinwagen]

yeah, all the eatons just turn into big heat pumps after 10PSI or so.

the smaller eatons are better suited for the small 1.6(the M90 will be very inefficient spun slow enough to boost at 10PSI)

I would prefer an M45, but the M62 is priced better for me.

-Owen

[rabbitman]

ouch man that stinks, a cheesy belt or did something else go wrong and jam it up?

[Powered by Spearco]

Sorry for your loss.

[truckinwagen]

not sure, the charger was in really great shape, so I am not going to say that something internal failed(it is possible, but unlikley)

the most likely thing is that the belt was bad from the factory, and failed.

I am leaning toward the M62...

-Owen

[truckinwagen]

well, just sold my spare engine girdle(thanks RadoTD), so I am in the game for a new charger.

I am going to buy the M62, just way more value per dollar than another G60.

for the time being I am going to get a new serp belt to run it sans charger until I have the new one ready to bolt on.(probably not until next fall)

I'll make an adapter to attach the eaton to the G60 bracket as it is there already and is holding my alt, etc.
the M62 has a boost bypass built into it(much better than the G60 TB one too) so the eventual twincharging will go well.

-Owen

[truckinwagen]

well, a little research shows that the M62 is reasonable efficient(not as much as the G60, but still good) to about 15PSI, and can be pushed to 20PSI before it starts pushing air too hot to use.

sounds like a perfect match for what I am doing.

I have a lead on one on the vortex, so pending what that guy wants I might have a new charger soon.

-Owen

[truckinwagen]

well, it is back together without a charger...




and the intake:


it starts and runs, like any N/A diesel, not very exciting...
but the intake is LOUD!
so very loud, it IS going to drive me mad, I just know it.

-Owen

[RabbitJockey]

that is unfortunate

[truckinwagen]

well, it runs good now, if a little slow.
took a drive to alyeska today, took me forever, couldn't go faster than 35 because of all the snow.
took me almost two hours to get there.

on the way back started to overheat, turned out it was low on coolant, a little looking shows that my water pump is leaking. damn.

so I need to put a new water pump in it too.

oh well, at least I can drive it around.

I am tempted to install the non AC alternator setup I grabbed for the time being, until I get the new supercharger setup ready.

-Owen

[truckinwagen]

looks like the leak is at the seal to the block, not the shaft.
so I don't need to replace the water pump, just pull it and check the seal(a fair bit of work as it is under everything else)

I am headed down to Homer tomorrow, so repairs will have to wait until the weekend.

new supercharger is on the way, a third generation eaton M62 that I picked up for $150. pretty sweet deal, originally for sale for $350, but didn't sell for about a year, the guy just wanted it gone.

not sure if I am going to adapt the G60 mount, or make one from scratch.
either way will be a fair bit of fabrication.
I am tempted to make a new mount to get the charger and alt closer to the block, so I can fit the intercooler behind the grill.

the fight goes on...
