39 vs 36 = about a 7-8% gain (3 of 36 = 1/12th = 8.5%). That's pretty legitimate!

The reason I'm intrigued by this is because here we have a product that was essentially taken off of a 1.8liter corolla engine (correct me if I'm wrong). That engine, in it's time, was rated 30city 40 or 41hwy mpg? Combine the better "breathing" capacity with a lower displacement and I think this could be of particular interest to the hypermiling crowd. In a way, you don't necessarily want more power to get better mileage, but rather you're trying to make the engine run more efficiently. Hence the -1hp +1tq is an afterthought if it improves overall drive-ability.

If I had the money, I would get an MI pulley, some sort of an intake manifold gasket (to lessen heat soak), this product and either keep the stock tb or get the mystical corolla tb that everyone is so infatuated with. Combine that with an injen intake (assuming anyone ever responds to my wtb thread) and I bet I could break 50-52mpg in the summer (44-46 avg this past summer).

Of course, this would all cost about $700+ so even with a 5% gain in gas mileage, I'd have to drive the car 10-14 years to make up the difference in saved fuel cost.
