Ok so I am getting annoyed with how my gt5523 is only making 25 lbs of boost. But I am a cheap a$$ so spending $600 on a 1.0 housing is not going to happen :hehe: The housing I currently have is a divided 1.18 housing with an internal waste gate. So with all this talk about spool flanges making turbos go vroom faster I have decided to make a non variable cheap :shake: version.
I will be blocking off the volute (official name?) closer to the exducer of the turbine which is a 111/100mm I believe and flows like the dickens. This will make my housing roughly a .6, Im well aware of the fact that this will probably choke the turbo more than Homer and Bart. Ill see how much das boost is made then if not where desired Ill drill a 3/8ths hole in the block off, check boost, then go 1/2 inch check boost then add another 3/8 hole and so on. The waste gate will be blocked off on this and if boost gets into the uncomfortable range ill do this crazy thing called let off the throttle. I am going for 35-40 psi wot. Once and if I achieve this the gate will be put back on for when I feel like spraying.
I have no idea If this will work how I want it to but figured what the heck may as well try it out. It will take me a few weeks to complete the test due to weather traffic and general lazyness but the initial port blocking will be happening tonight/afternoon, but testing would result in my death with the wet roads out. If all else fails Ill chop of the t6 flange and weld a new one on with no blockage and get a 6 billion dollar housing. I remember hearing about some sled pullers who have done something similar for large singles but have never heard of anyone doing this for twins. If you have any suggestions, ideas, insults, flattery, sexy pictures, funny jokes, idle banter throw em out there. Ill keep you all updated as well as I can. :Cheer:
