Small Schwitzer versus Dodgezilla
I bought a small Schwitzer a while back. It has a small compressor side(56 or 58). How do these compare to the 35/40 hybrids? I have a Dodgezilla/14 in my twin setup now and am wondering if it would be a waste of time or not to build a new hot pipe and try the Schwitzer.

21 psi will support 350hp with a clean tailpipe, so I'd say that the smallish compressor isn't that big a deal.
IMHO, the turbine side is what needs attention on these trucks. If the Schwitzer has a better turbine side (more efficient, less back pressure) then I would expect it to outperform a Holset hybrid.

It surges while towing if you are not running enough filter. The comp wheel has to be sized perfectly for the altitude/power level or it will surge.
This one has a 65 mm wheel, and a 14.77 dual port w/g housing.
Roman (RDLeader) is using one in a staged setup.

My B1 surges BAD when towing below 2000 (which is where the truck runs most of the time), so are you saying thet I don't have enough filter??
Could you explain more, possibly??
Thanks,
Chris

When he was right at 1700 rpm's empty he could get it to surge. When towing it was even worse.
We changed the wheel from a 66 to a 65 and crap canned his super restrictive, very small filter. (He was running something that flowed less then a k&n in a stock air box.
After we did that the surge was almost nonexistent.
I see you are running a scotty with a hole. I would say you have plenty of filter. I am unsure as to what the B series turbos uses for wheels.

People dont just run the S-300's right out of the box from switzer, they always modify them with different wheels and housings because they surge in stock form. You want at least a 62MM Wheel. or dont bother with it.
