[QUOTE="IUP99snake, post: 12503887, member: 7060"] It would be interesting to do a comparison with and without the blower, using something like a Procharger intake adapter (to reuse the factory intercooler), or just using a sullivan EFI intake. I'm not an expert on compound boost... I know it has some benefits, but I just can't get over the feeling that the benefits are, in large part, being outweighed by the parasitic losses associated with driving the blower. Someone else in here immediately shot my suggestion down to run a more efficient blower, claiming you can't run a twin screw on a compound boost setup. OK. Well, then why not find a more efficient roots blower that takes less HP to spin. Think of it this way: Let's assume that your blower adds 100 HP at the wheels. But it takes 100 HP to run the blower. Therefore, the blower must add 200 HP to the crank in order to produce 100 HP at the wheels. There's a point of diminishing returns. If you want to stay compound boost, get a ROOTS blower that is more efficient and takes less HP to drive. That's free power. [/QUOTE]
