Well i was runnin my car to the redline today, It was fine in 1'st and 2'nd but once i hit 3'rd around 6,000 RPM i got a loss in power then a huge boost in power. I think it is a fuel cut or loss but i dont know. I have a upgraded fuel pump and a T04E singe turbo runnin 10 psi maybe 11 psi with creep. Right now it has stock inj but it has a Power FC. Should this happen and what is it exactly? PS i have 1300 CC inj that will be in at the end of this week.

how old are your turbos? miles?
|
The turbo isent that old it has a small oil leak but i dont think it's the turbo. It was worked on and rebuilt like 5k miles ago. Some one told me it might be the ignition coudl it be?
|
You dont have any ingnition? That would probably be a BINGO
Your fine with the fuel you have, I have a ton more mods and Im still on stock injectors with and E also, no fuel problems. Your E is spitting oil? Where? Into the intercooler? Better not be... |
No not into the intercooler well at least i dont think. Damn i'll have to ask sevenspeed again they said let it go till after summer so it cant be that bad. Hum so the ignition is the prob **** that means MSD system and thats a ass load of cash i dont have https://www.nopistons.com/forums/pub..._DIR#>/dry.png So what type of ignition system should i get?
|
Oh JT how long till those C shifters come in?
|
HKS, MDI( I have) the HKS one is pretty decent for the $$
C`s man I was gone since early morning SAT, I just got back late last night, so I hope today or tomorrow.. |
Move your knock sensor off the housing and to the engine hangar and you wont hit any more fuel cut.
|
an MSD 6a isn't too expensive you can get it for like $130, you'll probably need more then one, most people run like 2 or 3 of them so i guess that would obviously double or triple the price tho.

Well i took it for another run today and once i again in 4'th at 6,000 rpm it cut out and came back on. I was watching the boost and it's not the turbo. So i feel it coudl be the ignition now. Is there any way around this i really cant fork over the 500+ bucks to do it right now, at least not for another month or two. What will movig the knock sensor do? And how do i do that?
|
The fuel cut comes on when you go 0.25 kilogram/cm2 over your boost setpoint. What do you have boost set at, and when did the power loss occur?
|
|
i have my boost at 10 psi and the cut off happens at 6,000 rpm
|
Well i went to sevenspeed today and my prob is fixed. Since i still have stock injectors in, my power FC was set to cut after 11 psi. Well in 3'rd and up i was getting boost creep above 11 psi and my power FC was shuting down the engine. So till my 1300CC inj go in george moved my boost up 0.05 so the cut wont happen in 3'rd and a lot latter in 4'th. Thanks for the help thou guy's

why do you need 1300cc injectors though?
I can run 1.2 bar maybe more I have a T04E, Trust 3 row intercooler, big side ported motor, ported and polished intake manifolds and the throttle has been bored out too, I have no airfilter(more air) and a full straight exhaust and a GTR fuel pump. STOCK INJECTORS all around... |

Im gauge less...
Yeah I know, someday.... What ever a GTR R34 nismo pump puts out hehe |
I dont know all they said is they didnt want be to run any more psi till i put in the injectors.

Stock injectors will take you to about 13 psi before you start pushing the safety margin. Its not good to run them at 100% duty cycle. This is with stock turbos though. His to4 will be flowing alot more air even at 10 psi. You shouldn't need ignition untill you are over 20 psi boost. If you are having breakup then your stock ignition has a problem. What plugs are you running? Any car with a decent amount of mods should be running 9's all around. For higher boost you can step up to 10.5 race plugs.
