Hey I wondering if running the AAM oil pan spacer with the vortech would be detramental to the charger if the oil was returned through the oil pan spacer!!

 

i dont think the vortech guys have ever discussed this topic

 

well its a good time to start for me!!!! Cause I'm on my forth charger now!!

 

there is a thread on it around here . Dont see why it wouldnt work .

 

You should already have the upper oil pan tapped . WHy move it ?

 

I never tapped the oil pan I just used the spacer and returned it through there!!

 

OH MY GOD!!! YOU DIDN'T!!!!!!!!!!! I did this myself initialy and had all kinds of problems. blown oil seal in S/C,high supercharger temps,slow spool up of the supercharger with mad belt slip problems due to the gearcase in the supercharger being full of oil and not draining properly. the oil return has to be above the oil level in the oil pan . THIS IS IMPERITIVE! it is not pressure feed back into the oil pan like turbos. it is only gravity feed.

 

SO THATS WHY YOU KEEP BLOWiNG blowers !!!!!

JK ! lol

 

I wouldnt have tried it my self . But I had thought several had did it that way with no problems

 

I don't think you are to far off on that being true.

 

with the oil level being lower than the blower . the thread that is around , most agreed that it shouldnt pose a problem . Guess it does slow up the drain back slow enough to back it up

 

****. I'm in the process of putting the vortech on. And just put on the JWT spacer. Should I expect to have problems. I thought this was a good route to go so you don't have to tap the block.

 

never to late to do it right

 

tap the upper oil pan!!! i cannot believe you guys even took a chance on something like this.

 

I use the APS oil pan and use the tap it came with

seems to work

of course I don't run my car hard until I have a minimum of 140 degree oil temp and of course use synthetic oil. That probably helps with the oil being easier to move

 

From a logical standpoint, the oil entering the supercharger is at 45-60 psi and tends to pool around the bearings (with a small drop in pressure) then proceed back to the engine. If you have your oil return at a spacer (and no kinks in the line) it is only opposed by the pressure generated by a few inches of oil in the bottom of the crankcase (surely less than 2-3 psi) and the pressurized oil from the return line would swirl into the bottom of the crankcase to be re-circulated by the oil pump. There would be very little impediment to oil circulation and very little increase in transit times through this secondary 'oil circuit'. I don't think this would create any undue pressure within the supercharger unit or any increase in the temperature of the oil. I don't think this presents any increase in the wear of the bearings or gears.

I think the tapping of the side of the crankcase was the cheapest solution for Vortech (instead of going to the expense of providing a spacer for the oil pan) and it does not present any significant improvement of oil flow through the supercharger.

Just my two cents based on 38 years of experience with mechanical toys (and I could be wrong, but I don't see how).

 

APS does it the same way with their turbos, I don't really see how it's any different with the vortech. Good enough for APS, IMO it should be good enough for a vortech

 

i'm using the pan spacer as well for my return. I think if it was a problem, installers like JT at PF would not say it was fine.


FL Boy, i thought you were going turbo? realized how expensive it was??

 

I still am dont you worry hahahahaha im just still wondering why my charger was going bad so fast and some people say it was the oil line and some people say it isnt!!!!!

So here is a question- How many people here use an oil pan spacer to return there oil from the charger??

 

wow. I never knew that my turbos had a pressurized oil return system.

you'll be fine using an oil spacer and returning the oil back into the pan that way! I've had no troubles with it on either a TN ST kit or on my current Greddy TT kit. both setups use gravity drain setups........just like a vortech!
