my 95 wrx is underpowerd and i knw it not being paranoid lol just deffo isnt kiking hte 280-290 it should be , goin for rolling road on thursday ,and take it from there but anyone got any quick ideas i can check myself ? nothing to mjaor tho lol cheesr adam

 

95wrx is only rated at 260ps (256bhp)

 

yer hks mushroom filter , full hks exhaust wid 100cell sports cat , and boost upgrade !!

 

Fair enough ,the filter may be sucking in hot air unless properly sheilded which isn't good.
How have you increased the boost?

 

i havent done naything lol the owner before the one i bought it off , !! well think the simple answer is goin to be get it ont he rollers 3pm thursday nd see what they say ! hopefully somthing simple and a quick fix , as had a lil tear up wid 2 turbo 2000s tht were running 245-250 and mine was exactly the same and i shud be di*ki*g them lol

 

Ask the guy you bought it off what he did.
My 93 wrx with a manual boost controller set for 0.95 bar hit 270bhp and that is just under the standard fuel cut.

 

he didnt do anything,and obviously doesnt knw that muhc coz he seem tot hink it was prtt damn quik , but i dont lol and no it aint anywer near as quick as it should be supposed ot be running 1.1 bar aprently but on gauge it only ever hitting .9 ,

 

sounds like a boost leak check all joins on the rubber pipework from the turbo to inletmanifold.

 

Has it been mapped properly ie. by a reputable mapper !

 

He might of been able to spell though.

 

Oh the irony.

 

Sweet isn't it.

 

What do you think that this peice of tat does then?

 

what would you recomend then ? only just got the car and 1st scooby so came on here for advice not fuking idiots !!!!!!!!!

 

booked in at engine tuner for rolling road session tomoz so will get my answers from people that want to help !!

 

Calm down, take a breath, the hks is prob sucking in hot air from the engine bay, the original setup would prob be more efficient, hot air will drop your power slightly, a fcuked cat will drop power lots, could be many other things. wait for your rolling road and go from there.

 

got a box around the hks filter with open front but yer thats what i thought go on the rollers tomoz and see what they say !

 

you learn to ignore the idiots on here mate.. forums full of em!.. id say heat soak from ya shroom filter.

 

id say boost leak!

 

standard boost on a 95 wrx is only 0.9 bar anyway so that is right.Not sure where you got 1.1 from as only 1996 onward STi run 1.1 bar standard.If the only mods you have is an HKS mushroom filter then its probably zapping the power and you are nearer 230bhp.Get a decent free flowing induction kit (if you must have one) and a nice cold air feed from the front of the car it will improve the breathing of the car dramatically

 

Youll not get a deal of help like that, will you.

 

What fuel are you running?

Tony

 

always sul, depends what garage im near at the time but always 97+

 

apparently it had boost tuened up , didnt say it was running standard boost , but all will be found out today fingers crossed at engine tuner !

 

Alan and the boys will sort you out , its always worth going to someone who knows what he is doing rather than internet diag. Alan is one of the best

 

so what was the verdict

 

verdict is , need new back box as packing is basically chocking up exhaust , bleed valve to be fitted boost turned up and set up again ! indeed its verry good to talk to someone who knows what they are doing ! so basically 3-400 and il be bk up to power and again !

 

No suggestions about sorting out heat management and the intake then?

IMO the HKS filter (tat ) or any induction kit is pointless without a decent heatshield or unless a cold air kit... and I think you might find thats what other well respected, long time members may be driving at...

 

martyn at engine tuner , said nothing wrong with hks mushroom filter and the heat shielt that has been made for it is verry good best hes seen does exactly as it should !!!

 

Ah right, I perhaps had misunderstood your description, I thought you ment your had a set up something like this.....



As opposed to something like this....
