1) How much does your gas mileage go down for average driving if you have a twin turbo? Single? Supercharger? Are they all similar in terms of mpg when driven average?

2) With A turbo, can you have a switch in the car that turns the turbo off and on? I know you can go between high and low.

3) Will 4.083 or 3.9 FD gears affect your gas mileage negatively in city driving? Highway?

Thanks in advance for answers, they are basic quesitons, and I searched and found nothing. I know a decent amount about all these and it bothers me that I don't know these basic questions.

1. Depends on your style of driving, you will most likely lose some MPG but not as much as youd think.

2. You cant just turn your turbo off, you would normally have a low boost setting for DD or different applications but you cant turn it all the way off.

3. Again a style of driving question.

Dropping $10k + on a twin turbo setup and concerned most about gas mileage isn't the biggest of your worries.

 

Alright, thanks man. I actually thought you lost a big amount of mpg with turbos, with all the talk about extra fuel lines and bigger injectors and such. I have 1 more question.

4) Does entering yourself into shows and such have a cash reward along with a trophy? Or just trophies? Assuming you got whatever place you needed for the cash.

 

^Depends on the show...Just about every car show will give out trophys, not as many with money. Maybe other prizes.
