The inline 5 cylinder Audi turbo engine has a great soul. A moderately high RPM engine with lots of good strong midrange torque and great peak power production. As with most engines, a certain level of increase in performance can be expected from the stock components with higher manifold pressure, but there is a limit. With time and many cycles, parts wear and become subject to failure. If you're building a high RPM, high power engine, having a strong rotating assembly is critical to the success of the build. Modern turbochargers allow for crisp and smooth air delivery, so having a set of connecting rods that can handle the punishment a modern ball bearing turbocharger can deal out is very important. The stock rods in the inline 5 turbo Audi engines, while safe to moderatlely high power levels, have been known to bend at higher BMEP levels and that can ruin your day.
The H-Beam rod from Carillo offers yet higher capacity as compared to the Super A I-Beam rod. These rods have a substantially higher area moment of inertia value ("I") as compared to the stock rods and are made of high grade 4330 alloy steel with a shot peened finish to minimize crack propagation. A very highly engineered piece that is put to good use in your inline 5, be it mornally aspirated or turbocharged. 144mm length and a direct bolt-in replacement for the stock connecting rods to retain your 1.66 rod ratio. These rods are ample for high powered inline 5 cylinder engines making over 750 HP and 8,000 RPM. Proudly manufactured in the United States of America and made of the highest quality materials. Price is for a set of 5 connecting rods, with hardware. Couple these with our forged piston set to acheive a very strong and cost effective upgrade to your bottom end.
