Hey All,
After spending some time searching existing posts for the following info, I'm hoping the moderators would consider pinning a 'sticky' topic within the "Supercharged 3.5L" forum category that gathers detailed specs and references for the V6 supercharger.
--------------------------------
"It's an Eaton R1740 compressor section in an Edelbrock housing made specifically for Lotus. The R1740 is a roots style with 4 lobes, 160deg twist." (Thanks @Porter)
Eaton TVS R1740
Main Eaton TVS Page
- Although some folks have also referenced "1750" when quoting from Emira promotional material...?
Here is a video showing assembly of what appears to be a similar (probably non-Lotus spec) Eaton/Intercooled unit from Edelbrock.
- Nice to see how the intercoolers fit in (similar to Audi 3.0L setup).
- Also nice to see where the bypass valve is, and maybe (just maybe), people will stop calling the bypass valve actuator the "throttle linkage"![Cautious :cautious: :cautious:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Assembling an Edelbrock Supercharger
Edelbrock housing part number or kit number (for parts reference)?
Is this Edelbrock kit identical to an Evora implementation?
- If so, which Evora(s)?
Any Evora-based DIY links for upper cover or entire SC removal/reinstallation?
B&C supercharge parts catalogue
(Thanks @Rudi)
Thread for Painting the supercharger cover
Part numbers for cover and gasket: (thanks @Time2Fly )
Cover 8891348489
Gasket A132E0169F
Upper cover bolt type?
- Torque specs for the cover bolts should be 10nM (thanks @VL3X)
Gasket/seal part number for housing to manifold?
Housing-to-manifold :
"Supercharger to intake manifold is 10Nm
It all starts on page 42-15 of the service manual." (Thanks @Time2Fly )
- bolt type or p/n?
Supercharger Oil specification?
Eaton/Edelbrock/Lotus recommended oil change interval?
Oil plug part number?
- torque spec?
Is this unit vacuum or electrically controled for the bypass valve?
- I'm guessing vacuum, since the actuator appears to have a chamber (bean pot) similar to the Edelbrock assembly video above
Is there a position sensor on the bypass valve? If so, is there a code reader / diagnostic tool that allows viewing or logging of the bypass valve position?
Stock pulley sizes?
Stock SC belt part number?
More supercharger stuff, just for fun:
Engineering Explained - Supercharger Type Comparison
Eaton TVS animation with a very different bypass and intercooler setup
FCP Euro SC oil change on an Eaton
Motor1 Article with some history: Rise and Fall of the Supercharger
---------------------------------
I'll continue searching and updating as I find details, but please post any replies with specs and references if you have them on-hand, and I will incorporate the data in the main post.
