I'm about to purchase my first turbo for my 08 tC, and I've been doing a lot of research. After reading the Turbo FAQ, as well as conducting a search, I couldn't find information as to what exactly constitutes a "conservative tune." The FAQ lists ~6 PSI as "mild," but would an 8 PSI boost still constitute as "conservative"?

The reason I ask is because I LOVE my tC. I know adding boost wont yield a 200k motor, but I still want to make my car last as long as I can.

What are your thoughts?

 

conservative tune would be :

8-9psi

11.6 afr

3-4 degree of timing being pulled


this is wat constitutes conservative

 

i like to thing my 3.5psi is conservative ;-)

 

Has long as you don't beat on the car all the time, you'll be fine on 8psi.

 

you can beat on the car on 8psi with no problem. i beat the hell out of my car for over a year on 13psi. then i started to have problems. so 8psi is not that bad.

 

^ do you think our cars can last on 12psi daily driven, if we are not beating on them?

 

people need to learn its not about the psi its about the cfm the turbo is putting out


but to answer your question its all in the tune if u got to ptuning i KNOW that on 12 psi your car will last if you dont beat on it, toan is a great tuner and if u find something wrong he takes care of it un like most tuners

 

7 to 9psi

 

So if 8 PSI is generally agreed to be a safe boost, how long would the engine last? The FAQ states that the OP never went below 8.7 PSI, and that his ride has lasted him over 8 months and counting.

What's the largest amount of miles have you experienced (or heard of) someone making on their tC with a conservative boost, as well as religious maintenance?

 

12k miles, 1 year on 12psi. 0 problems, same compression test results before/after boost.

 

chintastic had over 100k on his motor and he was running like 10-12 psi i believe

 

It all depends on what turbo how much psi on that turbo. And how you maintenance your car and tune ofcorse. So there is no actual time frame to know. All up to you.

 

Carbon,

Wow - thanks for sharing! If you don't mind me asking, how are your driving habits?

cburglb34,

Thanks for sharing! Would you happen to know about how many miles he had the turbo on?

 

"Conservative" I would clasify that as 11-11.5 AFR, but heck Im not a tuner just a hobbyist.

 

There wasn't a day that I didn't do a hard pull, plus I Auto-X'd the car...so I'd say I beat it up pretty badly lol.

Tuned to 11.6-12.1 AFR.

 

I know there are a lot of variables in it, but I'm just trying to find an average. I know that some tC's can blow at 6 PSI in less than 2 months, while other last for years at 12 PSI. I just don't want to see my ride blow prematurely - I love this thing .

 

Rythmnsmoke is who you want to chime in here, he's been boosted for 3 or so years.

 

Don't cheap out on parts and don't cheap out on the tune. Plain and simple.

 

Omg... bada**. You're an inspiration, lol. I was hoping I wouldn't have to baby it once a turbo gets installed - I don't like people cutting me off on the freeway .

 

2 years here of forced induction, most of it being turbo but there waqs an inbetween period wher ei was nitrous


i have always beat on my car everday, my motor is still fine and as far as i know strong made 243/245 on 6 psi
