The bore of the turbo exhaust housing was cylinder shaped and the hole for the exhaust intake did not transition into the housing very well. So I've smoothed that and re shaped the housing to direct more flow around the impeller
Ie. I Dremel'd a tapered channel around the housing. To get the gas swirling around the housing and impeller....
It's made a big difference... There is a noticeable rpm increase and is a lot less restrictive when blowing through it....
ATM I'm currently making a flange plate and dump pipe for the back of the turbo.... Out of a washer an a old HengLong alloy BB gun barrel.
My biggest focus is to be able to get the turbo to spool so I'm paying the most attention to the exhaust side. My plan is to see it the turbo will effect the running of the nitro motor before plumbing it into the carby.
and here is the test for a dump pipe.... but that has been removes as it was to restrictive. I might use a old header for the dump pipe
but I'm still yet to get the engine of my buddy
