A new question for turbo guys...

[SHO_DOODmorrris]

Hey guys,
quick question... is there any issues with mounting my turbo vertically where the ABS block would be as opposed to mounting it where the air box it. would make life a bit easier for me but dont know if it will damage the turbo. i dont think so but i thought i woudl ask. thanks

You mean mounting it so the shaft is vertical? Bad idea.

The turbo needs to be mounted so the shaft is very near horizontal, or parallel to the ground, and the oil drain port in the CHRA needs to be within a few degrees of pointing straight down. If not, it will be difficult for oil to drain from the bearing. If oil doesn't drain freely from the CHRA, it will eventually find its way through the shaft seals and into both the exhaust and compressor sides of the turbo.

I'm with st00pid /\

 

[somedude_001]

+1 don't mount it verticaly

 

[SHO_DOODmorrris]

yeah i found out earlier and forgot to post. thanks for the confirmation guys.

 

[SHO_DOODmorrris]

New question... for the oil drain, where do i put it? do i need to drill/tap the oil pan? or is there somwhere we can go already. thanks

Yes, you want to tap the oil pan. couple things I read bout it.
1. must be above the oil level.
2. minium size is about 1/2 ID or -8AN for ss lines
3. must be pitched enough, the more vertical the better.
4. dont use heater hose if u use barb fittings.....can cost u an engine!!!!!

Many ways to go about it. AN bulkhead fittings, welded, drill and tapped. I had a bulkhead fitting but took it to a guy and just had it welded to the oil pan. It will NEVER leak. The bulkhead IMO seam to easy to leak.

here an example of wat I WAS going to use. Its was a bulkead fitting. I just had the 90 welded to the pan.

 

[SHO_DOODmorrris]

shit... now i have to take the damn pan off. thanks..

-mitch

wait a sec... what about the oil level sender, couldent i just turf that and screw somthing in there?

 

[HotRodKid]

keep the oil sender ! its to low of a spot for the fitting anyways

1)the shaft of a turbo should always be level or near level,
2)the oil drain should NEVER be rotated more then 45* from straight down
3)never more then 30* from straight down is a way better plan
4)the oil line should ALWAYS be slanted towards the motor, if oil collects in it your screwed
5) the oil line should have at least a 45* slope, the more vertical the better
6)the bulkhead in the oil pan should be as high as possible
7) if you road race your car, the best spot for the bulkhead is front / center or rear/center
8) if you cant stick to these rules, you need an electric oil pump
and most important of all rules ...

9) dont blow it up

thanks guys. one more Q, what is the oil pressure our engines put out at idle and at max flow? just checking if i need a restrictor. i knwo the dsm TSi guys need a restrictor for the holset hx35 at their pressures but i dont knwo what ours put out. thanks again

-Mitch


edit found this

The minimum oil pressure when the engine is on load must be 210 kPa (30 lbf/in2). Maximum
permissible operating pressure is 500 kPa (72 lbf/in2) although 600 kPa (88 lbf/in2) is permitted during
cold start up. Under idling conditions pressure should not fall below 70 kPa (10 lbf/in2).

Oil pressure of 150 kPa (20 lbf/in2) must show at the turbocharger oil inlet within 3 - 4 seconds of engine
firing to prevent damage to turbocharger bearing system. A flexible supply pipe is recommended.

(lbf/in2=psi)

That blue fitting looks like my old pipe I used.

My friends will get this................

P.S 8an is too small im going with 10 or 12

 

[92sho16]

P.S 8an is too small im going with 10 or 12

I was told to use nothing less than 3/4 id line. Im not sure what that translates to in AN but i think -10 is close.

 

[SHO_DOODmorrris]

i know the stock dump tube on the holset turbo is like 7/8 or 3/4 so i might just use that tube and run a hose with a hose clamp over top of that but i kinda want to do it nicley with AN fittings and either that snaplok hose or the ss braided. ill prob go with 12 an just to make sure


oh and for feed line... -4 should be good eh?

im assuming you mean the oil drain back from the turbo.

the hole has to be above the oil level and the oil level sending unit should always be in oil, it goes off when the level gets below it.

plain and simple your gonna need to tap a hole above that area.

echo in here?

-an sizes are an expression of 16th

3 -an would be 3/16 id
10 -an is 5/8 id

learn something new every day... It would be nice if they just adopted the metric system though.

just checking if i need a restrictor. i knwo the dsm TSi guys need a restrictor for the holset hx35 at their pressures but i dont knwo what ours put out. thanks again

I thought the restrictor was only for all bearing turbos, because they do not require much oil to operate properly and too much will hurt spool time.

common misconception. It all depends on how much oil your turbo can handle and how much oil your oil pump can spew out. it wont assrape the turbo right off the bet but prolonged exposure to high oil pressure can blow out the oil seals. thanks for the replys guys and is -4an big enough for the feed line? thanks

I know for my supercharger it is -4AN line and the inlet itself is 1/8thNPT.
