does increasing the bhp make the car o to 60mph quicker and does this also increase torque?

Performance mods will increase both bhp & torque which in turn will increase 0-60 and all other 0-whatever figures.

bhp is essentially 'torque per second' (= torque x revs) so they are related.

It's suprising how many people don't know what torque and bhp are (I was once in that boat) - google is your friend...

http://vettenet.org/torquehp.html

0 - 60 also depends on traction etc., so there is a limit above which more torque/bhp won't help much as you can't put the power down.

that figure would depend on what rear tyres you have
standard 205 on 6.5" rims or drag slicks on 9" wide rims will make huge difference

tyres are a bit on the thin side consider getting wider rubber on the rear axle when you get replacements

earthing to get rid of stage 2 boost is an effective and even easy & cheap mod as you will get the full (2nd stage boost) from when your tubby reaches that boost up till redline

it will not up the bhp though, wont make you run 8 bar either but then you dont want it to make 8 bar :rofl:

to reach 0.8 bar you will need a boost controller, preferably an electronic one

for 350bhp theres a lot you need m8 as most parts max out at around 330 - 340, try this: downpipe + decat + air filter panel + cold air feed + afm + injectors + turbo + clutch + ecu + maybe fuel pump

so no you cant reach 350bhp without mapping by a tuner

He was making fun of the fact that you said 8 bar instead of 0.8bar. As there is a VERY big difference, i would like to see the size of the turbo that could make that pressure!!!! He meant nothing against you.:)
You want to run your car at 0.8bar. Get your self an electronic boost controller, and also some sort of fueling control like an apexi safc, and go from there. They will need to be fitted and tuned by someone who knows what they are doing. Ideally on a dyno.
