can anyone tell me the top boost psi should be on a standard 2002 18t 180bhp engine is please, thankyou in advance :smiley:
-
Around 12.5psi bud :smiley:
-
right think im getting bit more than that<will check exactly how much 2mora, was wonderin because ive had car for 2ish months now and it is extremmely fast and wid all forge stuff on it im thinking its had a remap, got into a bit of a race wid a cupra on saturday and i left it, my pals driven it and and says its fast, my 1st turbo so a bit of a newbie on em. it was drivin rubbish till i got a new maf on a couple of weeks ago and its a different car now.
-
More than likely been remapped :smiley: let us know about boost readings
-
if it has been remapped does it needa different maf, or just a {working} standard one ? maybe showin my inexperience now lol :smiley:

Just a map won't require a bigger maf...is there any reason you think that your maf is faulty?

Around 12.5psi bud :smiley:
I think it is less than that, my Octavia vRS was a max of 8psi standard and around 14/16psi mapped.
-
My stage 2 peaks at 22/23 psi :wink:
-
took it out today and gauge needle is hitting around 23psi, this car must have had a remap or something,plus with all the forge stuff on it it has to have been. had the car since november, its my1st turbo so on a steep learning curve lol im getting around 33 to 38mpg on journeys 25mile or longer if i drive it sensibly, does this sound right to any of you ? only asking bout the maf because when i bought it it soon became apparent that i needed a new one,since fitted 23psi is what ive been getting, thought u maybe needed a upgraded maf if u had a remap thats all. does 23 sound alot? and if not woould i still be getting the mpg im getting with that sort of boost ? on the over hand could the boost gauge be faulty ? any advice greatly appreciated :smiley:
-
it depends on what stage remap you have had or weather or not its a full custom remap as the previous coment to your says:
My stage 2 peaks at 22/23 psi :wink:
so it is possible your stage 2

Actually yes your right bud :smiley:

so if lets say its had a stage 2,is this putting massive strain on the turbo? and what mpg should i be averaging,same as stock?? and roughly what bhp are we talking? i was happy with it being 180 standard, dont get me wrong i like the acceleration when i put my foot down but mpg bothers me,and im not made of money and all this remaping etc will it cause me to be spending extra money keeping the engine in working order.is it easy to unmap? :smiley:
-
Mpg is about right and why would you wanna unmap it?
-
im a worrier bud , i love the car , but think if u tamper wid something it more likely 2 go wrong if u get my drift lol :smiley:
