compound turbo ideas

What are you running for fuel?? hx35/s475 should be good to 550-600hp. maybe a little more. 35/472 will be a little less and offer quicker spool up. should be able to get the s475 and piping for around $1900. Studs will be another $400. Depending on your fueling you'll see anywhere from 55-75psi of boost. I'd also be thinking about oringing the head and getting 110# valve springs. Just remember you need to tune twins after you install them!!

yeah but your pretty much maxing it out they will make more than 500 but not a whole lot more. have seen a truck gain 50hp just by doing a so swap being only change same day

Uncorrected?? Do you have a dyno sheet also.. Not saying it can't happen. Its just farely rare

You probably wont see much of a gain over running your single... If you swapped to an so pump you'd have alot more room to grow.
01Quadcab- I think I'm a little over the hx35's limit... it'd be more like 500-550hp. An I never said anything bad about the so pump.... I actually said they were better than the ho. I personally would never run anything but an so... Unless I did a ppump!

I'm not sure on the exact measurements, but I think the HO pump has 7mm plungers in it while the SO actually has 7.5mm plungers, which is probably why they are capable of more power. I believe the HO pumps used higher fuel pressure to help boost the power a bit, but actually used slightly smaller injectors than the SO engines as well.
