STI TOP MOUNT ON WRX

ive just recently fitted a sti top mounted ic to my newage wrx the car now makes a new noise a kind of induction type sound is this normal,ive made sure all the pipes are fitted on tightly

also the car seems to be using more fuel i drove down to blackpool and back cost £160
car is 55 wrx prodrive
cheers

I think the car shud b remapped to suit the new intercooler!!! Has the car been mapped before and is there any other mods done?

mods are forge dv sti top mount replaced the prodrive back box and boost gauge
how much would a remap cost?
I think it might be running rich as i get pop/bang fromthe zorst

You can get away with those mods without a remap, sounds like you have an air leak if it is making a new noise, this will also cause extra fuel usage.
Check the gasket between the dumpvalve and intercooler as the can leak from there, Did you fit the forge DV at the same Rome as the sti intercooler?

You shouldn't hear any difference when swapping intercoolers

I had that problem when changed mine and the air was coming from the dump valve found out gasket between intercooler and dump valve wasn't much cop

Def a new noise I can hear in the car
Like a induction sound at first I thought
Its the sound of it sucking more air
I fitted the dv with a new gasket and
And checked all hoses for leeks
I know these cars are thirsty but
Newcastle to Blackpool nd bk cost
£160 in petrol dose this about right?

All depends how you drive it mate round town I get 200 mile to a full tank and that's between 65 and 70 quid to fill I give it some beans then your looking at about 150 mile to a full tank if you stick between 70 n 80 mph on the motor way you will probably get the same round about 200 mile but all subarus are different there a lass on here who gets 90 mile to full tank if that makes you feel better

Definitely sounds like something wrong there. One annoying tw@t on here gets 300+ miles from every tank. Hopefully he doesnt read this and start posting, he's a right wonka.

Hav you blanked the old return pipe from the standard dump valve to the inlet before the turbo?
Or when you've been fitting these bits you myt of pulled that pipe out of where it goes onto the intake pipe before the turbo! Bit of a pain to get to lyk! Lol

Have u got a standard dumper valve try swapping it over I ha trouble with dump valves and when I went back to standard car runs a lot better it may be faulty
