Description
The Eventuri carbon turbo inlet elbow for the Audi 2.5 TFSI is a world first: a turbo inlet made entirely of carbon fibre. It was designed around three criteria: volume, flow quality and temperature. The inlet diameter grows from 72 mm stock to 103 mm and the outlet from 56.4 mm to 74 mm, for a much larger internal volume and a freer path to the turbo.
High-temperature pre-preg carbon fibre gives a smooth inner surface, where the stock and most aftermarket elbows are cast aluminium with a rough finish, and the continuous curvature keeps turbulence down. A CNC-machined flange connects to the turbo, and a silicone coupler with an integrated thermal spacer keeps the carbon elbow from touching the turbo; together with carbon's low thermal conductivity, less heat reaches the intake air. The elbow is finished in raw carbon without clear coat, which would not survive the heat of the turbo and exhaust manifold. It is designed to work with Eventuri's Stage 2 and Stage 3 RS3/TT RS intakes.
Key Features:
- Full carbon turbo inlet elbow in high-temperature pre-preg carbon fibre
- 103 mm inlet (stock 72 mm) and 74 mm outlet (stock 56.4 mm)
- Smooth inner surface and continuous curvature for less turbulence
- Silicone coupler with integrated thermal spacer against turbo heat
- Raw carbon finish, no clear coat
- Separate versions for left-hand and right-hand drive; the right-hand drive elbow has a recess to clear the brake fluid reservoir
Performance:
- RS3 with hybrid turbo: +14 to 20 hp and +30 to 35 lb-ft (approx. +41 to 47 Nm)
- Flow bench: 42% more than the stock elbow with the stock flange, up to 58% with the larger SRM GTX flange (right-hand drive version 52% with the GTX flange)
- On a TT RS with a TTE700 hybrid turbo and Eventuri's Stage 3 intake, BR Performance (Netherlands) measured 620.8 hp with this elbow against 606.5 hp with the modified stock elbow
Fitment:
- Audi RS3 8V Gen 2, RS3 8Y (non-USA), RSQ3 (F3) and TT RS (8S); left-hand and right-hand drive
- Not for the USA-market RS3 8Y, which has its own Eventuri part
- Supplied without turbo flange: order the stock-turbo, TTE700/625 or SRM GTX flange separately
Includes:
- High-temperature carbon inlet elbow, left-hand or right-hand drive
- Silicone couplers with oil-resistant lining
- Marine-grade stainless steel hose clamps
