I do not run 30-32 degrees on the Elky. Atleast not at WOT under boost. On the highway, yep run 45 at times.
Started this DIY turbo 250 with low timing (25) and increased it with our comfort level, esp with the minimal amount of control the engine had. Ended at 29 degrees. I am sure with a intercooler, the right compression, cam, ect the timing could go much higher. Not what we were doing here. Just trying to show what gains could be seen with a throwdown turbo setup.
