#876, "RE: twin turbo application ???????" In response to In response to 7
Not a flat 6 either - its an inline 6 - so all the exhaust ports are on one side which allows them to run a single large turbo. A Subaru has a flat-6 configuration, which is closer to a v than an inline, except the ports are horizontally opposed. A lot of the twin turbo cars are twin turbo because the v configuration would require a lot of tubing with a single turbo so its easier to throw a single turbo on each set of 3-cylinders not to mention quicker spool up which is good for selling. What has to be considered when looking at a setup like this is how much exhaust gas will be produced to spool the turbos. Obviously, it would seem a single turbo would be much easier to spool because it would have twice as much energy and half the parts. But, this has been done on a 4G63 using twin T-25's because of their small size which reduces the amount of gases needed to get them moving.
