over boosting help!!!

Postby luckettfrst on Sun Jan 28, 2007 12:15 am

if have a frst and was told that it had a 160 chip in it and as the boost cut kiks in at .9bar i am pretty sure it has. but my actuator gave up i brought a uprated one which came with a part number on it and it was the same as the one it was replacing. when fitted it gave me .7bar in 1st, 2nd and 3rd would just reach .9bar in 4th and would hit the .9bar in 5th at about 3500rpm in 5th. winding out the arm cured this giving me .5bar in all gears but i found out that this was with my wastegate being held open always. when i wound it in to just close the gap in the waste gate the problem came back. i was told that a amal valve would cure this as i didnt have one fitted but i gained a erst one and i have no idea if i have put the pipes to the right places or if the erst amal will work?? can someone tell me if the pipe connections on the valve have to be a certain way and where tha pipes are supposed to go to (they run from my turbo to the valve and from the valve to the acuator) or if the erst valve will work on a frst? asap plz as i cant drive it hard at the moment and i got overtaken by a saxo today!!!! help!!!!
thanks

Fiist off please don't use blue text and change the size thank's. If the amal valve wasn't working the car would go into limp mode i think i haven't had one on my car for a long time limp mode is when your car shack's and jumps untill you switch it off which restart the car which reset's it. If your car was chiped to stage 1 it should boost to 10psi as a stage 2 chip is about 15psi. If you not know if it's chiped go in your car and put your head in the passengers foot well and look up you should see the chip if there is one if not there would be a small plate over the hole on the bottom of the ecu you need to find out this info first to know what boost you can run. I take it you have a cheap boost gauge theses can be 5 psi out so there a waste of time when your car might be only running 8 psi which is all a standard frst should be running as 9 is on the edge of over boost you need to get a nomad boost gauge or auto meter there about £60 new or £30 off ebay second hand. What saxo was it as if it's the vts a standard frst are about the same on the power

sorry bout the size and color to start. have check the ecu and i have the 'hole' you speak of. that means i aint got much boost potential then. shall i get a standard actuator to stop me running more boost or what? i aint got £100s of pounds for a chip so standard setup will be resumed in the car. what about the amal valve? where should it connect to?? and will the erst one be ok. i dont have limp mode symptoms but i just try pulling the pipes of the valve and it came out of its casing so could it be fooked anyway?? oh i was a vts but one that i have happily beaten before as the driver cant drive!!!

Ok cool you want to get it to boost to 8psi the uprated actuator is fine and won't give your car any more bhp or boost it just make's it boost in a different way so it fine. Your amal valve sound's ok as you car would be shaking in overboost mode you have one pipe in one out and it should be pluged in. What you need is a very good boost gauge (not the one that changes different colours :lol: ) and wind the boost down by making the stem of the actuator longer tilll it is very low then you know for shaw that you are well under like 3spi when the car is cooled down to up the boost make the stem of the actuator shorter just 2 turn's at one time to make sure it right you need to go flat out say on the motor way and when your in 4th gear just before your rev's are in the red your boost gauge (good boost gauge) should read 8 psi that full boost then you know your spot on just do 2 turn's at one time when cooled there no point doing when it hot you will leave your skin on the turbo :aaah:

one in and one out but where do the other ends of the pipes go? and does is there a in and a out on the valve or dosent it matter which way round? the actuator is wound out to the point where it is JUST shuitng the wastgate and i have fuel defence cut in at 3500rpm in 5th.

oh i havent mention that it also has filter, exhaust, polished head all to aid air flow and a 360degree beaing built into the turbo on rebuild. will any of this make a difference to how well the turbo boosts or how much boost i get from it.

Your taking the piss mate 0-60 for a vtr is like 10 second's :lol: vtr is more like the xr2i. Vts's and frst (standard) are about the same That's like saying vtr can do a vts The frst must of not been racing mate mine was standard for 2 year and i raced load's of vtr's and they never beat me :P

It will help with the bhp but won't mess around with the boost. Your car need setting up

Not sure what you mean about the fuel thing? the amal valve stop's the engine from being damaged by turbo like if the actuator jammed open and the car was limp mode. If it wasn't working you car would be shacking all over the place

good point well made!! i have found that even a vts falls back on acceleration when the boost kicks in. 1.6 n/a engines just cant rev through the range as quickas a turbo'd 1.6.

so is it worth me taking the amal valve out and just running a pipe from turbo to actuator? and getting a standard actuator to stop my boosting problems?

No :lol: as your car would go into limp mode and you wouldn't be racing any one. You need a good boost gauge that's number 1 number 2 set it up your self as i said get the boost well down then adjust it bit by bit till you it 8 psi in 4the gear just before the red
