Tuscan connecting rods are the best rods available for your European engine due to quality, custom application specific design, and thorough testing. Each Tuscan design is different from any other design because they are custom-crafted and optimized by our engineers using the latest CAD and FEA software. This is in contrast to the industry standard which simply resizes standard designs to fit new engines. Each application is vigorously tested in our in-house engine test cell. We have gone the extra mile to design specific big ends for each application, keeping the bearing in place and reducing chances of failures. This results in a connecting rod that is uniquely strong and light, for the ultimate in performance and reliability.
Tapered small ends
These connecting rods have been designed with performance in mind. Making the Tuscan connecting rods stronger is one thing, but keeping the weight to a minimum is another. Through careful FEA simulation, we are able to reduce weight in non-critical areas of the connecting rods, making them lighter than other rods available. These connecting rods have been designed to incorporate a tapered small end, removing unnecessary material on the top outer edges, making for significant weight savings.
Application Specific Engineering
Each model is detailed out with a unique feature set that ensures proper operation within the unique demands of that engine. There is a particular emphasis placed on providing a stable foundation for the connecting rod bearing. By providing a stable platform for the rod bearing, much higher reliability is possible. For that reason, the feature set is not consistent across all models of IE Tuscan rods.
Engineered Performance, Tested Reliability
IE Tuscan rods for turbocharged applications feature a robust I-beam design for incredible bending and torsional stiffness. Additionally, an extensive iterative process lead to the unique egg shape of our rod beams, which lowers stresses as much as 20% compared to less evolved designs. This shape very evenly distributes the high compressive loading from a turbocharged engine onto the connecting rod beam. We then validated this success with over 18 months of field testing, powering numerous 4 cylinder VW/Audi engines with over 1000 bhp! In addition to being tough, IE Tuscan rods are also designed to minimize unnecessary weight on the connecting rod for an ultra balanced weight to strength ratio. Our engineering staff has spent countless hours trimming the fat- leaving exactly what is needed to get the reliability you want, with the weight you don't.
Finished And Quality Controlled In USA
This level of attention to detail is mirrored in the manufacturing details as well. Each set of Tuscan connecting rods are honed in the USA to tolerances of around 250 millionths of an inch! This ensures amazing bearing reliability you really cannot find elsewhere in this price range. These rods are as round and true as any rods money can buy.
Optional Rifle Drilling
To keep wrist pin wear at the minimum, all of our forged rods are available in a rifle drilled option. Rifle drilling forces pressurized oil through a small orifice placed vertically through the rod and further lubricates the pin and bushing. This extra oiling causes less wear and friction between the rod and piston and increasing the life of the internals. We highly recommend the rifle drilling option for street-driven cars, as they typically see more mileage put on them, but works well to extend pin life on any setup. You can select the rifle drilled option at an additional $25.00 per rod.
Rifle drilliing option requires matching rifle drilled bearings (IE part number: CAL-30V-RBSET-RD)
