The smaller ci motors need more psi to make the equivalent power to the larger ci motors. Thats all tom is trying to say.. My 198 ci motor made 750 hp with 35 psi. But theres more to it then that. Like compatibility. Having the right size turbine wheel vs the amount of exhaust gases that will be spinning it to effectively get the most out of the compressor wheel for a given cubic inch .. I started out with a 76mm compressor wheel matted with a 67mm turbine wheel . Then i realized at 35 psi is was
all done . All it did after 35 psi was make heat ! Same thing these blowers are known for. So basically after that, went with a smaller commpressor wheel of 68mm and a larger turbine wheel 70mm . Now i was able to make more power with a smaller turbo on the same motor. The biggest concern i see with this blower on the street is keeping the heat out of the intake. If you can do that you will be able to keep it togther with AFR and timing . So E85 will be a good idea as long as you can keep the heat out. If you cant, the e85 will not be enough and it will detonate..11to1 with a blower sounds like a stretch to me.. An intercooled turbo setup ive seen it done..
