[QUOTE="tt335ci03cobra, post: 15576096, member: 68944"] [ATTACH=full]87430[/ATTACH] [USER=137514]@Fordfourlife[/USER] Agree 100% that they can pull off the longevity of a 10psi fpc 5.2 with a blower since the 5.8 ran 14psi and 7000rpm without issue. The na mill of a trinity probably makes 350hp as it rolls off the assembly line. 14psi takes it to 685hp (662). Considering the fpc 5.2 voodoo mill makes 526hp to start, just 10psi would be enough for 880hp. It would only take 7psi to make 776 crank hp. Now, here's the kicker. Hellion made 1080whp with a 5.2 voodoo on 17psi (peak). Thing is, the traditional 100% gain of hp per 14.7psi dictates it should have only made 1020whp. This means the mill is over 100% VE, and accordingly exceeds the traditional calculation. What's my point in bringing this up? The voodoo mill loves boost. It's so efficient na that adding boost optimizes much of its head flow. Consider this graph from Hennessy, it made over 725whp with 1 full point lower compression will running 7.5-8psi. And realistically, the 8psi was in the midrange, and 7.5psi was at redline/peak. Using the traditional formula, the 473whp baseline should lose 1/12.5 (which is 8%) of its power for the compression loss. That would be 438whp. Let's say 440whp. The mill with 8psi would be ((8/14.7)+1) which is 1.554 times as much power. That would be 679whp. The traditional formula dictates 679whp. Hennessy made 733whp if I recall correct. And with 7.5psi to be honest, not the 8 I stated. That's a difference of 54whp in favor of how efficient the voodoo mill is. If I had to guesstimate what the VE is of this mill, I'd ball park it at 117-118%. That's a badass foundation for boost. For comparison, the coyote and boss mills were around 108-112%. Geek out.
