LS Race Y-Body, 7-Stage Turbo & Vacuum Scavenge, Drag Race, Right Side

LS Race Y-Body, 7-Stage Turbo & Vacuum Scavenge, Drag Race, Right Side

This is a popular dry sump system for GM LS turbocharged drag racing applications that need added vacuum capacity. Using Dailey Engineering signature series billet oil pan and 7-stage oil pump this system was designed to handle high G loads, make high crankcase vacuum and maintain constant oil pressure at high RPMs. 


Optional Pressure Gear Sizes: See technical page for more info. 

Increased 20%: 1.450"

Standard OEM: 1.250"

Reduced -20%: 1.050"


This system is designed for the GM Y-Body damper configuration and LS2/LS3 wet sump front timing cover. To install this system on an LS7 style OEM "Dry Sump" engine the front timing cover and timing chain will need to be converted to the wet sump configuration. For more information please see our Technical page. 


*A dual scavenge return, or a single -20 return oil tank must be used with this system.


*This system will not fit with the OEM motor mount and the A/C compressor will need to be relocated or removed from the engine.
