sorry, I'm rolling proof that your theory is wrong. Before my SC I got an average of 17mpg...now I get 19-20mpg. This was all recorded on my in-car nav and reset before each example. BTW, I'm at 17,000 miles on the SC, so that 19-20 is an average...that includes when I'm ON IT.

27 mpg is what I got on the drive back from Charlotte to Oviedo (~8 hour drive). I averaged about 70-79 mph (up to 9 over) the whole way back.

If you treat the S/C nicely, your gas mileage won't suffer at all. It takes virtually no extra gasoline to keep an object in motion once it's in motion.

To help with my gas mileage on the highway.

You might have had a fluke and got better gasmilage but it is the exception and not the rule.

Let's see... as I gaze into my magical crystal ball... no... F- the fairest of them all, I want to know how long an engine will last...

DUDE ARE YOU SERIOUS???

I believe this guy is correct. He's testing which one is "best" next week. Stayed tuned for the results.

The only thing I like SC over T is it's not under boost untill you get on it.

Otherwise gains with a T kit are better in torque department and need less boost to match the power. SC has parasitic loss due to pulleys/belt combo while turbo utilize just exhaust gas.

T's aren't in boost all the time. It's the same as the SC. You need to build boost. Right?
