Dan and I discussed this in great detail. We came up with that Ford probably dropped the compression ration on the Cobra motor to about 8.5:1 like they did with the Lightning motor. The they threw a blower on it. Its probably making around 8-9 psi with that compression ratio to only make 390fwhp. If they used the stock compression ratio they most likely used 5-6 psi and detuned the EEC for motor health reasons. I don't know if this blower will be intercooled or not. With the small horsepower jump its possible that its not, but yet again the Lightning only makes what like 380hp with a 5.4 so anything is possible. But I will tell you one thing...... with a lower compression ratio the engine should be able to hold up to much more boost than a pre 03 Cobra motor! :-D
