true but it looks like he has no fuel control and on the stock pump and injectors. So he'll find out real quick what is the max boost he can run it's called fuel cut :lol:

Most dsm experts say 16psi is the most you should run on stock fuel system. Anymore and you Are risking starving the engine.

yea I dont have upgraded fuel/fuel control

so 16 would be the max and still be safe?

15-16 psi is ok, i run 16 every day but i do have fuel system upgrades: fuel pump/safc, but on stock stuff your safe up to 16

Yes she does, and i say run about 16-17 as well. Every car is differant so see what yours is happy at.

yes...every car is different...you have a mbc so your boost should fall off...invest in a logger...handy tool

yeah, i know 16 is supposed to be the max/safest for the t25.... so i would def. think 16 would be ok for a 14b, but idk, i would think 17 wouldn't hurt either..

You cant judge by that for the fact both turbos output differnet CFM's. I wouldnt push the 14b no harder then 14 psi on teh stock fuel system just to be on the safe side. All in all, its your car. You will decide on what you will do. Its all in your hands.

Im sure a DSM expert told her that 16 psi was ok....

Just because you are running more boost does not mean that your car will be faster

Yes that I will agree with for the fact that everything is a factor.

1. Turbo Size (CFM's)
2. Timing
3. Knock

and everything else in between. My statement was not about the amount of boost taht she runs. It was stated that you cant compare a t-25 to a 14b.

There are way to many variables to consider like octane level, tempiture and humidity, condition of the motor, and the condition of the fuel system to really say this is the boost level you should run every day.

And here's another opinion.

Don't turn up the boost until you invest in a $90 fuel pump.

Yea the fuel pump is a must do for safety. Get a logger and tune your boost for now then raise it slowly tuning out the knock until your IDC get to high.

annnd you just came back at me with nnnothing.

but its funny because I wasnt the only one who said 17 tops. Funny how you pick me out of the crowd though, its cool, you'll grow up someday.

yeaa well at least your not buring your 14b out like...say 20 psi? :bigeek:
rasing boost supposedly doesnt mean more power...theres many articles about that one...a UICP will give you noticable gainss...just look att where it comes off of the sidemount...its rectangular and the section after the bov often flexs...you have a greddy bov so that should hold boost...since the bov is adjustable use it to your advantage and set it right...

and rasing the boost above stock...(boost shouldnt fall off when approaching redline with a properly installed mbc)...anything above stock is gonna burn the turbo out...but it will pull hard...i suggest you to get the dejon tool uicp...

so what if I get a UICP and a upgraded fuel pump what do you think would be safe then?

If you have a stock exhaust your going to drop boost

Maybe you shouldn't run your mouth so much on what you assume...it may end up embarassing you.

I don't have a Dejon UICP or a Walboro either.

please keep the thread on topic. this is a good discussion. I've always been told with the stock fuel system safetly on 14b is around 15psi. I'd also agree on picking up a logger. I just got one for when I get my car back out da shop.

The rule of thumb on DSM's is that rules of thumbs are mostly wrong. Every car is different, the only way to know whats safe for your car is to get a logger and keep an eye on things. People say the stock fuel lines and walboro 255 can't handle much over 400hp, I went 133mph at 3400lbs on stock lines and a 255... take everything you hear with a grain of salt.

I couldnt agree more. Eveyones car is deffinately differnet. There are many posts and question threads to prove this point amongst dsm forums. Everyone says this, that, and another but all in all you need to know your own car.

^^ good points both of you the bottom line is if you don't have a wide band, logger. or an egt gauge don't even think about rasing the boost
