This proves my theory that these cars don't need a twin scroll, my 2871 made full boost by 3000rpm, any sooner and you'd just spin the tires anyway

Thanks for the input.
Same engine: Same type of engine and identical rods (lowered compression). But two different cars.
Intake temps: See above. I have amended my post and included the numbers.
Blower: Yes, there is a blower. We will try to put a larger turbo on my car and make more dyno runs.
It seems to me that my hp figures are not bad (i.e. other forum members with a GTX2867R do not make more power on pump gas). But this also means that this turbo's hp rating (480hp) cannot be achieved on pump gas. At least not with our cars. That's disappointing because my Subaru WRX STI could (almost) reach the max. rated hp of a GT3076R on pump gas.
I was planning to use a 23 PSI map on my car. But this seems to be impossible if I use a GTX2867R...
