B.I.G SCOOB

can anyone help me,ive got a 94 uk turbo and was wondering what sort of boost it can run safely without the risk of pinking and detonation?i have some mods,exhaust,air filter,mbc and dumpvalve.i have heard that the older scoobs run at 0.9bar as standard,is this true?also while i am here does anyone know what the pig face graphics are on petter solbergs wrc car wing mirrors,its been bugging me for a while now!!!many thanks

There is no simple answer because as you increase the boost your engine will require more fuel. If it does not get more fuel then it is running weak, therefore gets far hotter than intended and with fair to highish boost pressure you can run into detonation which can wreck an engine ina couple of seconds if the pistons have not already melted and picked up in the bore.
Yours is quite an old car so it is fair to expect that the engine is a little tired so an increase in boost will likely shorten its life.
At some point, around 1.05 bar or some similar figure that others can confirm, you are likely to run into an ECU boost cut. This is a bad thing.
All that said, to reliably effect any boost increase you need Det Cans and a wide band lambda sensor and read out. You then know what you are doing and can avoid the pitfalls. Your ECU is capable of slight tolerance so you might get a little boost increase and remain safe.
To do the job properly, as well as the above, you need a mappable ECU such as a Link or Apexi Power F.C. both of which will be something like £750 fitted and mapped, new.
BTW, if you are going to do this it would be best to be running on Optimax and preferably 1ml/litre N.F.
I hope this helps.
