dump valve problem
 

Hi im tottaly new to the scoob's so bare with me, i have just bought a TK M20B subaru impreza wrx94,,which is about 300bhp,to 350 bhp, it has a baily's dump valve fitted ,now the problem is when it works it makes a funny sound not like a dump valve should,i have been told it is because it is not big enough for the engine, but i dont think that is the problem, im thinking of taking it off but im not sure on how the pipes go to put it back to normall, pics would be great ,or is it best to keep a dump valve on it, and if so which is the best one to put on,
any advice would be great ,
oh and i have 3 pods 1 oil preasure,1 oil temp and a 3rd which im not sure of all i know is that when it reaches 10 i have to change gear as when i go over the 10 the engine sound crap
please feel free to take the p**s:luxhello:

give baileys a call on 01763 246660, probably need a stronger/bigger spring.

knocklink
aka cocklink

anyone

sounds like u need dump valve with higher psi rating if ur running 350 bhp. Above ten psi u must be getting some detention be careful that can destroy ur engine in seconds, what fuel do u use.You need a dump valve to protect turbo from stalling

i dont quite understand about the psi any info would be gratefull,like how can i lowers it and what will that do to the perfomance ect ect:confused:any thing to save the engine but keep a bit performance

u dont waqnt it lower than ten 14.7psi is a bar of boost so ur not getting all out ur car if it runs 350
a knocklink will tell u if it is det or get a garage to check with det cans. my car was doing that and was cured with a set of coils

what type of fuel do u use
how high have u had the boost

the other gauge u have is a boost gauge it is showing ur boost in psi

Ok mate, if you still have your standard re circ dv, then all you need to do is place it back in between those 2 black pipes and where that nice piece of blue pipe is job done:thumb: although i cant see the factyou are running 300 bhp should cause your dv many probs

YOU....WILL....NEED....TO.....CONTACT......BAILIEY S.....AND.....HAVE.....DV......UPGRADED

or go back to standard recirculating, or by a better dv. Standard baileys dv are not stong enough for modded cars. Phone baileys and ask em yourself. Obvoisly your not willing to listen to my advise:lol1:

i just use the normal unleaded and the psi is on 10

I HAVE LISTENED TO YOUR ADVICE BONNY LAD AND I AM GREATFULL..:lol1: BUT WE ARE NOW ON ABOUT PSI :luxhello:

is your car a jdm? if so i would recommend using optimax or at the very least sul

thx m8

it may be knackered m8

yeah use optimax that will help with the noise above ten psi. If ur running 350 bhp ur car should hit about 17psi try optimax and let us know how the car goes.

what type of car u got anyway

is it a jap import

I Got this m8 just 2 days ago but i really wanted just a normal wrx not this tommy kiarra wrx, But i guess i have wanted a subaru for some time i just took this, its a nice car but its bouncy as hell and to fast up the box for my likes but it sticks like f***in glue needs a t cut and a set of better wheels but it will do till i get a normal wrx

fast up the box cause of power change ur springs it has been lowered that will inprove the ride nice car tho
so how high has ur boost gone to

yeah its an imports

goes to 10 then the change, but it goes that quick its unreal

has it evr gone higher than 10 what does it go to in 5th when flat out

if i do go over the 10 which i will admit i have done a couple cos of not changing quick enough :eek2: the engine basically complains and just holds back,so to speak, as for 5th never really took it that far
the subaru is all new s**t to me but what a nice car they are

yeah it sounds as if it is pinking bad detanation mb caused by the fuel run optimax if ur staying below ten ur missing out on what the car can really do what is the sound like do u know when the spark plugs and coils were changed

I think they were changed about 1 month ago m8, its ok up to the 10 after that it seems as though its restricted, maybe a good thing saves getting a new engine ,the engine was rebuilt recently i have the bill for £2500,
here is a pic off engine , its spottless compared to the pic

just wondering cause mine is a 95 wrx import i have not got power of urs but my bosst goes to about 17 to 18 psi thats why i thought urs was low

have u taken it up to any speed in 5th say on motorway when u go above ten does the engine make noise if so what kind of noise if u go above ten what does the boost gauge do

never had it above 10 in fifth,when i go over 10 in the other gears the needle goes nuts and the engine just dont want to know, there is only 15 on the gauge

is it 10 or 1.0 u should be able to hold car on full boost in 3rd 4th and 5th no problem instead of lifting of when u get to ten i have a thought to what it could be but is the gauage 1.0 or 10
