*Regarding the to4z map if that's what it is. it seems a bit hard to read but it looks like it says 65% efficiency at the top island of the compressor map, which also requires more pressure to get there. Just doesn't seem as energy efficient is all I was saying.
but not bad it actually looks really good for an old school single, I like em.
*regarding the 10lb's/min -5 vs T04z 20lb's/min which is essentially 7psi boost and neither have cracked the wastegate at that pressure and they are both identical as the dash 5's are used as twins so it's 10lbs of air from each -5 totaling 20lbs/min.
Look at the popular wastegate pressure ratio of 2bar which is (1bar boost)
it shows the -5's out flowing the T04z by 10lbs/min.
I have had the pleasure of going in a fully built stroked ca18 180sx imported from Japan which had one on it and it was mega still one of the loudest n quickest cars I'd been in.
