disagree - i see 80wtq & 90whp gains around 5000rpm, thats pretty dramatic.. look at it this way:

i promise that if you listen to me for turbo advice you wont be disappointed

here you guys go! this is the low boost run at 1.55 bar boost, red = flat tip blue = cupped tip. obviously the red tip is the winner at this flow rate. I can not find the high boost run on my laptop, its on the other computer. the blue had a slight advantage at the higher boost, but red still spooled faster obviously

that is 100% incorrect - the billet wheels are typically slightly heavier by a couple grams. I have not seen any single comparison where the billet compressor wheel was less weight. believe it or not many of BW's cast wheels like the S200SX 7670 and S300SX 9180 (66) are just as good as the EFR series' FMW counterparts, they just have a slightly different trim on the compressor side

no this will not happen

the FMW billet compressor wheels

the S300SX3 66 is an excellent turbo - and shares the same turbine blade aero as the EFR. the compressor wheel is also badass, in fact its almost as good as the efr, but way less cost and much better availability. That particular turbo is ONLY available with the cupped tip (the flat tip does not work well on that blade shape and size, so was never put on the market)

your turbo is almost identical to this FMW turbo, its really a great unit!!
