hey guys got a ls turbo...all the sudden out of the blue its starts bogging like crazy, i cant even get through the gears barley.Its slow as ****!!!! does not pick up at all! It sounds a wrx, like its breaking up. I just put brand new spark plugs bkr7e 11 gapped at .028..i have no clue on whats going on. I hear the fuel pump turns on. I have dsm 450cc injectors (precession turbo 880cc on the way) but it ran perfect with those ..u think its the fuel filter? any help would be great guys thanks!!

 

Is it throwing any Check Engine Lights?

 

could be the map sensor? disconnected or something?

 

no code!

 

has 3 bar map sensor with a pherable chip for the 3 bar...



its driving me nuts!!!!!!!!!!!

 

do a leakdown or compression check and come back with the results

 

are you tuned...?

 

ok so did a compression test following this link http://www.c-speedracing.com/howto/c...t/comptest.php

ran the car until it got warm then did the test.

now the the piston thats closes to the cams which i believe is cylinder #1 read 160 cylinder #2 155 #3 155 #4 145 (i always forget which is which) (WOT) when tested

 

yeahh all the sudden just started bogging haven't got a tune in a while but its been running fine! then all the sudden it starts!

 

here is my build

eagle rods
>> JE pistons(9:1)
>> Port and polished head
>> Feera valves
>> Crowler cams(409)
>> skunk2 cam gears
>> Crowler retainers
>> Crowler springs
>> edelbrock X intake manifold
>> AEM fuel rail
>> AEM fuel regulator
>> Block guard
>> T70 turbo
>> 3"downpipe&exhaust
>> tial38mm wastegate
>> Walboro 255lph HP fuel pump
>> ARP head stud
>> precision 880cc( just ordered on the way) has 450cc dsm now
>> omni 3 bar

use 94 octane

 

anything guys?

 

compression numbers dont look great, but they also dont look bad

i dont get how your running that setup with 450cc injectors

i would talk to your tuner and see what they say

 

thats how i got it...but what u think is causing it to bog!

 

I say get a decent set of injectors in the car then get it tuned. what Engine management is it running? If there is just a chip in the ecu and thats how you bought it then maybe crome or uberdata? I would look into something like Hondata s300 or AEM with the setup you have.

 

you properly damaged something running untuned

 

nope!!! found the problem...guy before me had the injectors wired janky and thats what was causing it to misfire!!

 

oh yea i got 880cc precision injectors that will be here on the 8th, and hondata s300 will be soon!!! you think it would be safe to drive it with the injectors in it with a phearable.net chip telling them exactly what i have untill i get s300?

 

if your ecu is set for a size injector, you need to stay with that injector till you change it in your ecu and install. it sounds like your trying to find out. i hope your not driving it around with the wrong injector, your duty cycle will be off if so. example 550's in the rail, 750's in the ecu = lean, very lean

 

get it tuned, you could take the chance if you had a wideband

 

you should be fine on a basemap to drive it around, but i would stay out of boost untill you get the new injectors installed and tuned

you have a pretty nice setup so get a good tune and keep it that way

 

got it thanks man!! will post results whenever i do get it tuned!!
