... there's a "reference" road you use for seeing if that latest mod made it faster or not

 

When you spend all of your $$ on a turbo kit 1 month after you got your drivers license!

And then start upgrading that kit before you get it.

 

...when you have 500% more $$$ in boxes than the purchase price of the car...lol.

 

...when you start buying parts for your upgrade build when you haven't finished the 1st.

 

When your turbo blows more than your girlfriend.

 

When 2 out of 3 of your cars are turbo and the turbos are running twice the OEM boost.

 

When you can't remember the last time you drove a car WITHOUT forced induction.

I actually can't. :(

 

when you go on a diet(skip breakfast and lunch everyday), not to lose weight, but to save money so you can buy turbo parts.

 

when you're on your 5th NA to turbo project in 5 years

 

When your changing your motor more then your changing your underwear. OR
When your car spends more time being built in a year then it does being driven.

 

when you start using cracked turbine housings for paperweights

when you accept the fact that the first time someone new drives your car, they will stall it because of the clutch

when you need 3 cars because 2 was not enough to guarantee you'd have a daily driver.
