What is the max boost a stock auto. tC can handle without any problem?

 

Boost doesn't kill a forced induction engine, horse power and the tune does.

 

But boost does kill auto trannys if too much force is applied.

 

Boost never touches the tranny. Like Bumper said, boost doesn't kill, its the amount of horsepower you make on that boost. And you can't give a definate "cutoff line" for what amount of boost will make a certain horsepower number because it varies from car to car.

It has been said before, if you are asking these kinds of questions, you shouldn't be going F/I. If you have done all your research on the turbo systems and what is safe for our cars, you wouldn't need to ask this question. The search button is your friend.

 

There is NO simple answer to this question, no matter how many times it gets asked.

There are so many other factors involved in running a turbo "without any problem" than just the boost you run. Firstly... have it installed properly. Secondly, have it tuned properly by someone that knows what they are doing. Thirdly, have all the necessary "extras" to help prevent issues. And still... even at that point, at low boost, you can still have problems.

Also, things vary from kit to kit, from what other things you've done to your car, to your driving style, and what exactly you mean by without any problem.

Adding a turbo to your car makes it necessary to have a much more hands-on relationship with your tC day to day than a stock tC.

By searching, you will find that there aren't too too many of us auto owners running turbo at excessive limits. One guy had his transmission slipping when he was running around 15 (? I think) psi. I've had mine up around 12 psi, and occasionally felt the tranny slipping there. I now have it around 8 psi, and the car runs fine.

 

Its not a PSI level....Its your power.

250whp/250tq your tranny slips.

 

if any one knows, it would be 318 tc

 

I make 270 Whp and 255 Tq and my tranny doesnt slip at all.

 

and u sir have a 5spd...

 

Take it from 318, he's made more than enough power on an Auto to know what it does and doesn't do lol.

 

word i didnt know you were talkin about autotradgeics
