i have a stock gsr on 310 with 7psi of boost,boost is fine untill 5000 rpm,it feels like the car wants to die,im not over boosting,i have fuel,can it be i have too much fuel,bad map sensor?

 

fuel setup please

 

check your air filter

 

does your gauge go into vacuum after 5000rpm??

 

im running stock fuel pump on rc 310cc injectors at 45psi,im not running an air filter,no my guage stays at boost,can it be a leak in my piping?also im running all my vacuum lines are t off one vacuum line,could that be it

 

Do you have an FMU?

 

nope

 

Are you just using the 310cc injectors and stock fuel pump? what else, please tell me that you have at least a fmu....whats your entire set-up

 

its a stock gsr motor,victor x manifold,chipped ecu,7lbs of boost,310,stock fuel pump,str fuel rail,sx regulators set at 45psi,no i dont have a fmu,also have a 255lph fuel pump but didnt install yet because didnt think i needed it for 7 lbs

 

Man, that engine is on borrowed time if it is not already mortally wounded.

You MUST run an FMU with that setup.

Sonny

 

To add to the matter, what did you gap your plugs to? Just curious... a lot of people seem to forget to go .030-.032. A word to the wise, dont boost until you add the FMU to your setup.

 

thanks for the help,do you know what fmu set-up,should i run?i only ran it twice over 4000 rpms,turbo has only been on for 2 days,i go hook up a fmu right now,let you know if i have boost

 

hey,i checked my friends setup and both wasnt running an fmu,both motors run great and made over 300 whp,i coudnt get an fmu today,so i was wondering do you really need it?im thinking a boot is leaking and im flooding my motor with 310,but i cant find one,thanks again for the help

 

I guarantee you that you are not flooding your motor. 300whp on 310s??uhh i dont think so. You <U>need</U> to put an fmu on your setup before you start boosting again.

 

and check that cat. make sure it isnt stuffed w/ crap from you running rich on your low end

Ok first off this is why turbo's get such a bad name, people doing crap like this and not doing any research before hand.
He's a little knowledge for you.
1: most kits come with a inline fuel pump AND a 12:1 fmu for fuel upgrade. The fmu provides more fuel under boost by raising the fuel pressure as boost rises.Without it your NOT getting any more fuel under boost. you need more fuel to burn with the extra air....
If you decide to ditch the fmu set-up you can, but you must provide more fuel another way.
One way is to use larger (440cc) injectors and a v-afc or smc. You use the v-afc to tune the fuel curve under boost.
or you can go stand-alone I.E programable engine management, where you can run even larger injectors and YOU set all the parameters so it will run like a factory turbo charged engine....
What your doing is basically slapping a turbo on and hoping that it works magically, Not going to happen...
I'm going out on a limb here by saying that i doubt you have a few friends that have turbo charged honda's making more then 300whp, if that was true they would have already informed you of what you need to do to make your engine run happy, and you wouldn't need us because they should have already informed you. If you do have these friends they are idiots, friends don't friends boost stuipidly.
Are you even runing higher octane gas?
I don't mean to sound like i'm coming down on you, but please, please do some research before you blow your engine, i don't want to read a post titled "how did my engine blow".......to some searching on this site and with your "buddies" ask around what other people are using for engine management and how they like it. I'm sure most people on here will be more then happy to help a noob learn, but i also know a lot of people also don't have time to help a ignorant noob.......please be a good noob .......come back when you are ready to learn.

 

b16ahybrid,
why dont you read my posts before you start saying ****,you dont know me,or know crap about my car,i wondering was there another way because i coudnt get an fmu at the time,you think im dumb enough to drive the car the way it is,as of the car i got 440 and hondata and its going to dyno soon,i was asking for help,not some dumb replies from some *******

 

I thought his post was justified (and informative) since u didn't sound like you knew what u were talking about. He sounds to know his **** so I would listen and not be a dick.

Thank you.

 

I agree with Fbp00si, b16ahybrid's post was informative. You haven't said a thing about your supposid Hondata setup until this point, so how are we supposed to take that into account? You said you're running 310's at slightly raised fuel pressure, which, as b16ahybrid said, is NOT a good idea at all.

 

Damn noob's. They come on this site for help, and when they get it, they get all pissy!

B16ahybrid has shown you the light...so listen up and not get all defensive.


PS being overlyspecific doesnt hurt at all on a webboard...try it sometime
Peace

 

I had that problem when I first installed my turbo and it was because one of the vaccum lines was hooked up wrong. What is you A/F guage doing at 5k?

 

by the way it was my fuel pump,i got a new fuel pump and it ran hard,NO i didnt hook up the fmu,also its was still on 310 with no hondata yet.
b16ahybrid,thank for the help anyways
