another boosted 3400 thread
 
Picked up the new toys yesterday:

She needs some new thrust bearings, figured might as well start a thread.

It appears the only place to get the bearings is here: http://www.superchargerrebuild.com/?page_id=6
Should i get the rebuild kit with mechanical seals or ptfe/viton seals?

Good luck with the rebuild! Man I miss my boost!!!

k6ng6r00 04-27-2012 06:23 PM

I emailed and this is what i got back:
Quote:

Mechanical is like what the factory uses , seals against the back of the thrust washer. Lasts the longest.
PTFE is an aftermarket alternative that seals on the shaft.
Sounds like i should get the mechanical seal.

Where you get that swag @ homie?

Contact the guys at 928motorsports.com They have anything you need to rebuild any part of your charger man.... they are freakin' awesome to deal with. That's who hooked me up

I did, the girl on the phone told me they only sell the parts for a v1 or a v2...

MMGT1 04-28-2012 06:43 PM

Something wrong there dude. They told me to contact them for anything I needed. I got my seal and bearing from them!

k6ng6r00 04-28-2012 08:52 PM

Hmm ill call them again and see what happens.

So in theory is there any possible way to dial in the tune with a supercharger so good that you get better fuel economy? or is it always going to be worse no matter what because of the pulley and everything sucking down power?

Only as far as it is possible to increase mileage over stock on a tune without the SC. In other words, tune it for better mileage while it is stock first. The SC will then decrease mileage when installed, but you may get a net gain. Not likely, though.

If it was a turbo could it be done? Im just thinking all these new little boosted eco shitboxes getting 30+mpg with turbos and whatnot, does boost allow you to get more energy per fuel molecurle or something?

Nope, just more (air + fuel) per unit of time

Can i use this for the oil feed & return??

See how the oil filter (blue thing) comes down at an angle? It's probably a major complaint for anyone who has ever done an oil change on a 3400 and doesn't know to punch a hole in the filter and let the oil run out. Regardless of that trick, IMO all oilfilters should be vertical, like the 3100:



I'll try to get a pic of mine later today, but the 3100 has this adapter thing that threads onto the block in the same location as the 3400's oil filter, but it is like a 45 degree adapter, facing the oil filter straight up and down.

Also, this adapter has two holes in it, both of which are blocked off by 3/8 drive set screws. Basically, it's a spot to hook up oil (cooler?) lines for turbo applications. Theres no need for any modification either, it's a GM part.

This has simply been for informative purposes. I've known about this since I was searching for 5-spd tranny's in junkyards, but never thought to share until just now, so for that I'm sorry everyone. But there, if you're going turbo, this is a very good alternative to drilling holes. Also if you want the convenience of a vertical filter, from what I can tell, it shouldn't interfere with the AC compressor. Like I said, FYI.

Its just unclear whether or not it will work properly.... if the set screws he is talking about function as an inlet and outlet it should create a loop that would feed and return the oil correct? The way im imaginining it it would be the same plumbing as if you were using a sandwich adapter for an oil cooler, except instead of an oil cooler its a supercharger...

your talking to a noob when it comes this in depth :biggrin: I leave things like that for people like chris (C2) to take care of.

Why would you return oil to the filter your taking it from... Just return to the oil pan and get a sandwich plate and feed from it.. People have been doing it for years and theres a reason for that... It works better than anything else.

But ive been on the road all day so maybe I read your question wrong

Because im trying to think outside the box and work smarter not harder. There are oil sandwich plates designed to create a loop, as opposed to just adding an accessory fitting. My question is, what happens to the supercharger when the oil is pumped through it like this, instead of just trickled on top and gravity drained from the bottom. This would basically just supply a higher volume of oil than what "people have been doing for years" but is that a good thing or a bad thing?

xXManwhoreXx 04-29-2012 06:34 PM

I dont know much about superchargers but with turbos to much oil fives you blowby and can cause coking of the bearing after time

k6ng6r00 04-29-2012 06:52 PM

I just looked at the inlet on the vortech its really small... the oil wouldn't be able to make it through the supercharger fast enough to not starve the engine of oil... nevermind. Even if the inlet on the super could be drilled out, and even if the additional pressure didnt push oil into the inducer, it probably would still restrict the oil from getting to the engine...
