Without trying to start something, I'll just throw this out:
271.9 hp @ 3200 rpm / 446.3 tq @ 1900 rpm at the wheels and that was on a dyno dynamics 450. DD's are widely recognized as the stingiest dyno's out there and they are nicknamed "the heartbreaker" because of it. Those numbers are without any power adders like Meth, propane, nitrous, etc. I do have post turbo water injection (devils own progressive) but it was inop that day (and inop since then) due to a roached pump.
I won't say what turbo I use because it's not popular round these parts and it only starts controversy that doesn't need to be in this thread. I know what I use and it works for me, that will have to be good enuff. That's not to say I'm not up for a new experiment when my current setup wears out.
The turbo is a part of making power on these engines, but not the only thing that matters. It's more a supporting cast member than the main character in this play.
There are many misconceptions rolling about regarding turbo's on a 6.X. I also won't go in to that either as it would just be more controversy that doesn't need to be here.
Mine is limited to 13 psi max before it pops off (yup, it's wastegated. yup, it makes use of the OEM vacuum system). Something that was denounced as not possible and build the power I'm seeing, many times, in many places, by many people.
Yup, it runs strong. Yup, it gets nearly 19 MPG. Yup, it runs below 1100 F when towing.
It took nearly 8 hours on the Dyno to sort that all out. It was a fun day for all involved and a very good mutual learning experience.
I will also say that Ferm seems to have a decent handle about what's going down underneath those big thick head castings....take from that what you will.
So start a new thread about your final build already! There are many ways to get power out of a 6.5 some being easier than others. :thumbsup: WTH we could use a little lively drama around here for a change. :hihi:
