Whats safe PSI for standard MK4 GTi 180Bhp
« on: 21 September 2014, 14:39 »
I'm just trying to learn as ,uch as possible at the moment,

so what is a safe level of boost to run on a standard 180Bhp GTi... Before i start with remaps, bigger injectors etc...

And i have to say i am a total convert, why i've never owned one of these before is beyond me.... sooooo much fun

I would leave the boost alone until the car is mapped. I blew my engine running 22psi on the standard map

No worries, i dont plan on turning it up... I just need to make sure its running correct

with the N75 its spikes at 15psi and then drops to 10psi,

Is 10-12psi a nice and safe limit? :smiley:

I know how dangerouse it can be running too high as there isnt enough fuel to mix, and thats how pistons get melted  :wink:

Ya 10-12psi will work with no problems. I think that 15psi is the stock boost for the 180bhp engine

Sorry, im a bit of a pain... i like to get as much information as possible before i start to mess about, just so i know my safe limits and that i'm not going to kill my baby.

I've never had a car that makes me smile like the Golf... its even better than the Calibra  :cool:

If you do what I did then you will be smilling all day when you pass evos and skylines at 160mph

320bhp. Nobody thinks a golf gti is that fast so everyone is supprised when I pass them with ease. My car is limited to 160mph but it will do more if I delimited it.

Its the same to drive as a standard golf. I get no torque steer at all in dry weather but if its wet the car is mad to go left
