Have you done a comparison on the two? They're not far off from being the same...-Jack

If you get a twin scroll manifold that will help a bunch, are your pistons over sized as well? Head work, cams? I am thinking all these will help. It's not going to ever spool like a vj20 but for how large and capable they are it sounds like it wouldn't be bad. I have only found a handful of people who have yet to run these on a Bp.Ian Boyd- Bellingham, WA (click vehicle to view)

spool valve may help, you could also try bullseye's .70 a/r turbine housing...is not longer twin scroll and would spool a few hundred rpm sooner.-Jack

yeah what rpm range will the hx start spooling? i was lookin into buildin my own spool valve only not using the spacer plate style but using the turbine its self it looks like it will have alot better flow when blocking and then i can also use a divorced manifold and get the most out of the twin scroll set up heres the link http://www.enginebasics.com/Advanced...ve%20Test.html

Are you building a manifold for the twin scroll? Or are you just re-flanging something? Just trying to find out if it's going to be the proper firing order to even make use of it's design.-Jack

its been awhile since i posted on here had to hold off on the hx project for awhile started a few different projects lol but atomic what rpm does the hx start spoolin up for u? what manifold are u running and what spool valve are u running? i have herd good and bad about the valves. im just not sure what one i should run i guess the only down fall of the valve would be high back pressures while cruising because the valve will be shut just lookin for a little more input

I have an HY, not an HX.
I think I have full boost at 4k? At that point I am too busy trying to keep the car in a straight line / not die to watch the tach/boost gauge. I think there's a video of the car in my build thread and you can kind of get an idea of the power delivery.sigpic
