Has anyone ever compared the RWD vs AWD dynos. I would expect RWD to put more power down, but it seems that it's almost negligible.
You would think so, and that is typically the case. However, Nissan/Infiniti's AWD systems in recent years have been very efficient and from what I've seen the difference is negligible on these cars. If there is one, it's likely less than 10WHP stock.
