I've recently fitted a boost gauge and pyro gauge to my safari turbo'd GQ (50,000kms). Boost was 7 psi (no intercooler) and exhaust looked like a petrol ie never any black smoke. I've now turned the boost up to 8 psi and adjusted the pump to give me about 500 centigrade after full throttle for a couple of minutes. Question is, when does this become a problem as far as melted pistons are concerned? A mate has just fully rebuilt his 1HZ cruiser engine (safari turbo, non intercooled) after he played with the boost and fuel!!
