Complete system with V-3 Si-Trim self-lubricating supercharger adds 47% more horsepower with 6.5-7.5 PSI at the stock redline.

Tuner kits are available with the oil-fed V-7 YSi-Trim supercharger, supporting up to 1200HP on modified vehicles.

System Components

• 10-rib supercharger drive design allows for maximum belt traction and stability. Features:
  • 3.80” drive pulley
  • Dedicated (stand alone) configuration
  • Steel SFI-approved race-spec replacement damper (ATI Performance Products)
  • Heavy duty automatic drive belt tensioner
  • Hard anodized billet aluminum idlers with dual bearings
  • Hard anodized billet aluminum 7” crank pulley
  • Premium 10-rib drive belt
• Multi-plate supercharger mounting bracket assembly features:
  • Billet aluminum front and rear mounting plates
  • Laser cut steel intermediate plate for increased rigidity
  • Billet aluminum spacers and high-grade hardware
  • Dual position automatic belt tensioner mount
  • Front plate configuration allows for simple change to manual idler adjustment for use with “cog-drive” applications (see notes below for accessory options)
• Fuel system upgrade (complete systems only) includes:
  • High flow 66 lb/hr replacement fuel injectors
  • Custom injector o-rings
  • “Plug and play” harness adapters
• ECU re-flash (production method TBD)
• Air inlet assembly includes:
  • Custom roto-molded ducting. Maintains 4” diameter equivalent cross-section throughout. Locates filter behind headlight for cooler inlet air temperatures
  • Silicone sleeves
  • Stainless steel clamps
  • High-flow air filter
• Discharge and charge cooler assembly features:
  • High-capacity welded aluminum charge cooler core (15.6”H x 20”W x 3.5”) is capable of supporting at least 1000 HP.
  • Aluminum Vortech Race compressor bypass valve
  • Silicone sleeves and stainless steel clamps
  • Mandrel bent 3” aluminum charge tubes for high flow and minimal weight
  • 4” aluminum throttle body inlet duct and billet aluminum MAF housing
  • Integrated air-straightener provides laminar flow through MAF for OEM idle quality and driveability

Modified Vehicles

Custom ECU reprogramming and a fuel pump voltage booster / high-flow replacement fuel pump is required if any modifications have been made to the vehicle, such as:

• Revised supercharger drive ratio (pulley changes)
• Aftermarket camshaft
• Cylinder head modifications
• Large diameter headers/exhaust
• Enhanced supercharger air inlet
• Non-Vortech MAF meter
• Relocation or removal of Vortech supplied flow-straightener from discharge assembly

Parts/Upgrades

Field upgrade from V3-Si to V7-YSi requires support assembly 4GE155-020. Includes necessary clamps, silicone sleeves and elbow
