From my learnings I came to the conclusion that any knock was going to do damage anyway so better to avoid it with use of high octane gas. I've actually had a few instances on E30 when things have...

Howard ...... maybe running 30% Ethanol would yield similar results to W/I on both counts (power and gunk/wear) ..... I don't have any long term teardown results to go by however.

Another thing I see bandied about here is how larger turbine wheels always flow so much better than smaller ones . This can be misleading IMO because It's the combination of wheel size plus AR that...

T3 Vs T4

Been reading about this topic on here and see there seems to be the view that T4 turbine housings flow better than T3 ones with the same AR. I think there are cases where this may appear to happen...

I have basically abandoned any further attempts to progress this due to the similarity with the Pratt & Whitney patent . I tried to contact them but was met with a computerised email wall !
