. PERFORMANCE:
• Wide-open throttle flow: 1600 +/- 50 SCFM @ 20” H2O at WOT.
• Designed for drivability; no tune is required (highly recommended for optimal performance).
• Max Area ETC scalar : 5396mm²
• Max Geometric/Flow Area: 7466mm² (do not use as area scalar in tune)
• Fully tested before shipping for sensor and motor operation, response time, and airflow.
FEATURES:
• Body and Sensors calibrated as a match set, zero intrinsic calibration issues
• Porting Taper and Upstream Bore with Velocity Stack (Lip & Bore Reduction)
• 16 Ra Microinch, Diamond Polished Surface Finish (Lower Skin Friction)
• Dimpled Pattern on shaft trailing edge.
• Dual-purpose hole pattern, the innermost part provides a direct fit to the MSD and all LT1/2/4 manifolds/superchargers, or aftermarket superchargers.
The outermost provides a direct fit to the LT5 (ZR1) supercharger.
BENEFITS:
• Essential component in high-performance engine modification, with exceptional high flow capacity
• Lower weight to power ratio at part throttle, for a more nimble/spirited driving experience
• Linearization and smoothing of the curve for a more predictable response and crisper shifts
• Immediate response right off idling while keeping idling function undisturbed (No Hesitation/Stumble)
• Does not require tuning to run, but tuning is highly recommended for optimal performance
• No drivability, idle, tuning, or similar issues relating to similar-sized throttle bodies.
• More air/power at every single throttle position after idle.
• Easy Installation
Inlet Coupler & Transitional Spacer ARE AVAILABLE FOR PURCHASE SEPARATELY.
