MSP with FCD past 10 PSI Safe

[SOSPEED]

How are you guys running over 10 psi.. Every time i hit 10 psi it hits so type of cut off. Fuel maybe?? Lets say i turn my boost up to 10 psi or higher and take the car out and hammer it as soon as it hits 10 psi the car feels like it hit a brick wall. Anything below 10psi the car runs like a champ.. Will the FCD help or could it do more damage than good by taking it past 10 psi?? Has anyone had the car on a wideband or exhaust temp using this FCD and running more than 10 psi or had it dynoed??

so fcd = very high chance of blown engine.

pretty sure that alof of the guys in the zoom zoom boom club were running some type of fcd. couple that with hard driving at 10psi and i think you might have a rebuild on your hands pretty soon.

maybe im wrong though ..

 

[NeverSober]

I think you are wrong................I dont have a fcd. But I have run 16psi without hitting fuel cut, except when the temps dropped. But I was running 13psi daily and beating the s*** out of the car and running various other boost levels above 10 psi. And I still have not blown the motor.........but that does not mean that your car will not pop at 10 psi. Things happen, but I dont think there is a very big chance that you are going to blow your motor at 10 psi. Numerous other people are running that with no problems......but just remember you gotta pay to play. So dont b**** if anything does happen, just know that there is a chance.

10psi stock = DEATH

 

[NeverSober]

No..............I ran 10 psi stock and my motor is fine. Gbourdon was doing the samething as me too..................

wait till its a little warmer and youll be able to run 10psi, the air is too dense at colder temps.

 

[ca_deal1]

Hum, i am running 7.5 psi daily, only once a while I will go to 10psi. But every time I try to go over 10psi, I had the same problem.

 

[warrier04]

ya .. i would not try to defeat the fuel cut - just deal with it now and wait until its warmer ..

fcd is bad joo joo ..

someone watches ren and stimpy (i think... right?)

you can drive your car at 16psi all day long-here is the tradeoff. Your motor was designed to last the life of the car at stock boost levels. If you start pumping up the boost with no supporting mods and tuning then you are seriously beginning to take the life of the motor into your own hands. To give you an example. the n/a tripoint 2.0FS motor is designed to last something like 25 hours. at 10+psi on an otherwise stock MS, i dont see your motor lasting too long.

i would not go over 8-9 psi without supporting mods.(without at least exhaust or you will start blowing headgaskets and be heating the motor to undesired temps) If you are making any power, then you will run out of fuel running 10+ also, so you will need some fuel management. I run more than 10+psi, but look at my list of mods...i still think im cutting it pretty close. I would upgrade the IC with a new SMIC, throw on some exhaust and make way more power at 8psi than an inefficient 10+psi. (plus not blowing the motor is a good thing 2) Since an efficient 8psi with out perform 10+ psi no problem. With my new FMIC and the rest of my od I am going faster around 9psi than I was boosting 14psi and had not 2 many mods.

What's Stock psi Set at? (MSP 2003.5)

 

[speed1016]

6.5 or less. Some are more but on average around 6psi.

 

[PGFracing]

I don't know much about turbos, but isn't that extremely conservative even for a stock turbo. Aren't most stock turbos around 7.5?

 

[warrier04]

^^ compared to what?

different turbos push different psi's ... my friends f250 turbo diesel runs about 25 psi, but it also has pretty brutal turbo lag because it's bigger than my t25r.

 

[PGFracing]

Oh I was reading on some turbo info and it seemed like it said most turbos, 4 cylinders and v6 were around 8.0 and that the factorys really leave them on the conservative side, but from what I've read on this site, most people don't recommend going over 8 psi with stock internals. I've found this site so far to be reliable and a great resource, I just recently did an engine swap and wouldn't have accomplished without the help of this site, the dealers KNOW NOTHING, and gave me all the wrong answers. Any how just trying to educate myself on turbos before I mod my car. Thanks for the help.

It's all based more on the design of the engine. The stock rods on an FS-DE are not known for being bulletproof.

 

[PGFracing]

Thanks that seems to be the consesus. What about replacing the bearings with ceramic bearings when replacing the bearings? We found gains with these, but we also found they wouldn't last. You heard anyone doing that?

 

[akeem1003]

Well, from what I have learned. If you want more boost, you have to change your injectors, fuel rail, and fuel pump. That will stop hesitation and turbo lag.

 

[PGFracing]

Seems like that maybe true if you want to go over 12psi. Other wise just internals, seems to be what many are saying.

 

[Gbourdon]

I have 52K miles, 10psi, stock motor.

Motor has seen 12 psi for a couple months and 15 psi for a week last summer
