[Charlieessex]

Hello i have a 1.8t golf at the moment i have a baileys twin piston dump valve and a k&N induction kit, im planning a audi tt225 front mount intercooler, tt225 injectors with inlet manifold, t4 replica turbo kit and cat back system. i would like a reasonable amount of power but i dont want something thats unusable, what sorta mpg would you get running such modifications under normal driving conditions ? and being FWD what power is enough so it doesnt just squeel its nuts off everytime you pull away lol thanks charlie

aswell as uprated clutch of course

Easy way to find out power is use flow rate, what is the peak air the T4 can flow?

Realistic power with the 380cc injectors will be 300bhp
Stock cat and down pipes 210bhp.

You need to be looking at K04 turbo is its a usable car your after.
