[QUOTE="`pr0digy, post: 784491, member: 554650"] If your increasing boost at all on the volvo's (or any turbo I assume) - ALWAYS run the most octane you can get, 91-93. Boris over at turbobricks sells a knock detector kit, basically sets off a light if your knocking, although volvos will retard timing if they sense knock. Stock volvo turbo's are only good to 15 PSI (and that's the upper limit) - after that you'll need a bigger turbo, as the little ones stock start to superheat the charge air... Also, you'll be running out of fuel by 15 PSI, if not before. [/QUOTE]
