[QUOTE="Snkbyte, post: 7043906, member: 8724"] No that is way off, here is the exact text from the MM&FF website. The engine was responsive to timing and rpm changes. Urist opened the wastegate by making one turn on the knob and started with 14 degrees of timing. Utilizing just [B]4 psi at the turbos [/B]and [B]16 psi at the manifold[/B], the power registered 611 rwhp and 646 rwtq. That's a far cry from the 385-rwhp output that bone-stock '03-'04 Cobras normally put out on the Dyno Edge chassis dyno. We wanted to see some big numbers, but the Hellion crew stepped things up, one chassis pull at a time. Another run was made at 14 degrees and at the 6,000-rpm limit, with the only change being an increase in boost. Output was 846 rwhp and 720 rwtq, as [B]boost registered 23.70 at the turbos [/B]and [B]38.50 in the manifold[/B]-this combo needed more timing. Urist inserted his opinion: "These turbos needed to be hit harder down low, and the fuel curve had to be leaned out some more." It was time to make big power, so the timing was upped to 16 degrees, and the Cobra was run up to 6,500 rpm. The results were 1,048 rwhp and 900 rwtq, with [B]turbo boost coming in at 26.8 pounds [/B]and [B]the manifold registering 41[/B]. One more pull was made, and Urist cleaned up the fuel map a bit and put the timing at 19 degrees. The [B]turbo boost showed 27 psi[/B], while the [B]mani-fold saw a peak of 44 psi [/B]due to increased engine rpm. Spinning the blower harder will result in a greater manifold pressure. Final output was 1,188 rwhp and 1,015 rwtq. [/QUOTE]
