I would say they know a good bit about how to build turbos. Go here and take a look at a 1055 HP dyno graph using one of their singles with nitrous

i run one the pro street 66 it is the upgrade from the sledpuller 66 they have. from what they said the sledpuller uses the same internals as the sps 66 and the version i have has the newer style turbine wheel for a faster spool up wich is suppost to be the same as the silver bullet that just came out. the reason i went them instead of industrial injections models was because htt has alot better prices and htt uses alot better bearing setup. i can put alot of fuel through it with my setup and it is very streetable with no surging. even with tst turned down it still spools alot faster than i expected to. they also have great customer service if you call them they will answer all of your questions and they aren't all pushy trying just to sell you something
