This is a pretty general question regarding turbocharged cars. If someone were to swap out their stock turbo with a larger turbo, would their cruising fuel economy (sayyy 60mph) with the larger turbo be better than their cruising fuel economy with their smaller stock turbo? Logic tells me since the larger turbo spools later and hits max boost later in the RPMs, you’d get better mileage with the larger turbo.. but I’m also not an expert on forced induction and I can’t find any literature online.
My particular setup is a North American Audi Q5 tdi with a dpf delete, 3” to dual 2.5” straight pipe exhaust, Darkside intercooler, and Malone Stage 2+ tune. I’m looking at the Darkside GTD2872VRZK turbo and I’m wondering about the outcome of mileage compared to stock. I currently get 39-42mpg on the freeway and I’m only willing to go with A larger turbo as long as it won’t hurt my mileage; my car is primarily a family trip car but also an all-in-one fun car for me. Thank you for any input!
