Hi new to the turbo ownership so please bear with me recently bought a 20vt with a k & n filter, boost gauge, and the prv set at 1 bar in all gears but not chipped? My question's are when I pull away very fast in 1st etc the cars clutch slips but if I boot it in second while moving it goes well without any slipping is it just wear or can't the clutch cope with extra power? Also how do I check the prv setting and if it has been chipped etc?
Thanks any info gladly received

The clutch should handle this no problem so I'd say it may be time for a new clutch.

Where's the biting point on the pedal, if it's close to the top then it'll confirm the above.

the clutch should hold 280-300 bhp unless launched all the time! so just sounds like a weak clutch

A new clutch should hold to 280-300 bhp, but thats not true in itself, as its more related to torque than bhp! And I woudl say a standard clutch wouldn't last very long at that power and related torque!

You need to know how old the clutch is, they can last anywhere between 50k and 100k miles, but could be more and could be less depending on usage! Do you have a receipt for a new clutch anywhere?

i do agree and yes it is torque related but most tuners said that around 280-300 is the clutches limit if not lanuching all the time

Tuners are wrong if they are stating bhp for clutches and need to be slapped for it

i know its a torque rating but most tuners know what sort of torque will get wiht a certain bhp!
if motor mech and powerfiat both said your ok on that sort of power i belive them!

Thanks for the info I think it is time for a new clutch it does bite high up. Any info on which, and any answers to the other questions?

Don't you have a boost gauge?

Thanks or the info what about the chip do I need one with the otther stuff or is it ok as is? Or do I need to check if it has been chipped?

It sounds like the car needs a new clutch if it's starting to slip.

You can usually adjust a PRV with an allen key.

If you want to check if it's chipped try getting hold of a standard chip from someone else on the forum and fitting that to see if the performance drops.

Thanks for that so you can't tell by looking at the chip ?

Have a read of this.

Thanks again, would I get any gains from buying a gtech 1 chip anyway?

A GTEC 1 chip is suited to a standard or mostly standard car. Gains are approx 20-25bhp IIRC. You can buy a GTEC 2 for when you have more mods, eg FMIC. There is information in the 20VT guide in the FAQ.

You should try and get hold of a standard chip and fit that first, there is no point in buying another GTEC 1 if you already have one installed!

Ok thanks again was just thinking I had a standard chip, so might be better of buying a gtec 1 to see if there is any difference as I think my car is mostly standard. Than paying probably as much for a standard chip.I thought with what has been done allready to my car a gtec 1 chip might be needed.

Hi, the fact that your car has a PRV fitted would suggest to me that it might already have a GTech chip fitted as this is what a lot of forum members seem to recommend as the standard electronic bleed valve tends to allow too much overboost after fitting this chip, try getting it rolling roaded.
