Ah! So is this it? (Fuel pipe gasket: 17555AA040)

Yep, that's it.

Does anyone check the oil level on their supercharger? I don't see an easy way. I guess it shouldn't go anywhere but it feels weird to me not to check its oil, and to leave it for 100k miles. Especially after reading about people filling their Jackson and Sprintex kits with oil after finding oil consumption

Always check your oil. It could mean that you'll have to buy another SC if it runs out of oil and you don't know.

The oil might not have anywhere to go, but heat will evaporate(?) it eventually.

Right, makes sense, how does one check the supercharger's oil?

You have done this? I'm very interested to hear how.

I've got mine off car right now and take a look when I get home. From what I can find, it looks to take 5.2 oz of fluid. Eaton does make their own replacement fluid, but it's kind of hard to find. Many other TVS system owners use GM supercharger oil. I would expect to use gear oil like found in a diff/transmission, but there's a lot of people using 10W-30 out there. If anyone knows, let's hear it.

Just wanted to add this from Eaton:

Q: How often do I need to change the oil in my supercharger?
A: The sealed oil reservoir in a supercharger is designed to last the life of the vehicle. Changing the oil is not recommended unless you suspect contamination, leakage, or other issues like bearing failure. Also, if your vehicle has an abnormally heavy duty cycle, such as racing or towing, you could consider changing the oil at regular intervals such as 20k, 30k, 50k, or 100k miles depending on usage.

There's no serviceable port anywhere on this thing. Looks like the two rotors aren't even mated by gears so much as driven by direct interference. If there is oil in there, the it's in the back of the case and requires disassembly of the rear cover. at that point you may as well grease bearings.

toast · 01-24-2020, 01:54 PM

That was my point with my comment to kev0. He has a sprintex and assumes the edelbrock is the same. It is not user serviceable without total disassembly.

So I did a thing over the last few days...

Having the MAP sensor in one of the runners is a fundamentally bad idea because its readings get screwed up by resonances that are created in the runner as the valves open and close for that cylinder. The erratic readings created are the reason Delicious made the Dbox; it is just an electronic low pass filter. When it works it is fine, but it can cause a number of issues.

I welded up a small aluminum box with a vacuum nipple on it (it was my first time welding aluminum with my TIG and I clearly need to work on it). I mounted the MAP sensor in the box, plugged the hole on the runner with the stock MAP sensor and then connected the box to the port that normally goes to the bypass valve (I have my valve teed into the brake booster line so that it only sees vacuum).

These are two WOT pulls before and after, you can see how much better the MAP signal is and you can feel the difference in the seat.

We are now implementing LSPI adjustments in all our tunes since November 2019, which includes version 28.00 and higher.

A short education post on what we have been spending a LOT of time on (within our tunes) over the better part of the last year in order to remove LSPI issues. We worked with other professional tuners, motor oil companies, and even vehicle manufacturers to understand what the issues are and how to best mitigate this issue while maintaining power and response even on 91 octane fuels.

You may ask what is LSPI. Low Speed Pre-Ignition (LSPI)

This trait is inherent on high compression, forced induction, direct injected engines, such as the BRZ (with forced induction) and 2015+ WRX, that can cause the combustion to pre-ignite at low RPM's and high loads.

Here is a good article on what the issues are and what we are trying address in tune, along with other physical changes.

https://www.motor.com/magazine-summa...-pre-ignition/

We have found a few key items within the tune to mitigate this issue while trying to offering safety, drivability and power for daily commuters.

Some other things to watch are the oil that you are using in your engine. Cars that are prone to LSPI, please make sure you are using an oil that is SN PLUS rated.

Make sure to speak to your tuner about LSPI and how to best mitigate these issues through the type of oil you use, adjustments within the tune and even the brand of fuel you use.

That sounds like exactly what blew my engine.

toast · 01-27-2020, 05:30 PM

Why do you think that? You were driving at 1500-2000 rpm and got on the gas hard when it went? At the upper limit of that rpm my edelbrock only makes about 2 psi of boost (I've never floored it below 2k and only did it then because Zach wanted a WOT log that started at that range).

If a car is turbo'd you can get a lot of boost at low rpm, but I can't see that happening with an SC.

This seems like more of a problem with people driving small SUV's with automatic transmissions than it does in a small sports car, where hopefully people know to downshift instead of lugging the engine.
