car looks well built so I think my observation is pertinent. this turbo is laggy compared to FP black
nice black setup will make 300tq at 3800.
this turbo hits 300tq at 4400. thats an enormous disappointment if you ask me. good single scroll tubular will do that and make far more power.

Fp black isn't even in the same ball park as this turbo. Say what you will about it but this turbo is much much bigger then the black. With everything done on the wheels this thing doesnt spool that bad. I mean yeah it is a little laggy from a dig or from low rpm but this statement is like someone running a stock evo turbo or a evo3 and going to a 35r and saying wtf its laggy.
plus you guys are dumb to think you can just keep making the wheels bigger to make a better turbo out of housings made for 300whp. the black is already too big. in order to max the black out you have to destroy the spool by eliminating the twin scroll in an effort to reduce hotside back pressure.
for me this turbo is a turd. take it or leave it. love it if you want. I could care less if you want to make you car no fun.

like evo 3 going to 35R . your smokin crack. this EF4 may be bigger than a black but its not that much bigger. and the question is is it better? I think its not even in the same ballpark. meaning the black is worlds better. RYU car made 570 tq on stock evo 9 block at 4100 rpm. and that was on pump gas/alky. e85 spools faster and makes more power. this rev4 made max 460 as early as 5400rpm. THATS FUGGIN LAGGY.

apparently you have been ignoring all the nice black dyno graphs. I guess just keep looking at the slow spooling incorrectly setup ones. if it makes you happy and wins you arguments.
I am done here. The EF4 is a lag monster from where I am sitting.

im going to agree with you tho.. this turbo is much laggier then the fp black.
either way i have multiple fp black cars hitting pk tq before 5k in 3rd gear heres 2 i found:
https://www.evolutionm.net/forums/ev...444-385-a.html
https://www.evolutionm.net/forums/ev...psi-93oct.html
keep in mind evo 8 head vs evo 9 will effect the spool also.. this cars an evo 8 but the most recent black i did on 93 444/385 with ebay parts is a evo 8..
the fp black does spool a good bit quicker though. a perfectly tuned fp black on a evo 8 will see full boost around 4600rpm (30psi). as shown: http://oi53.tinypic.com/25qd828.jpg on 93oct (also speed density)
There is no way the ef4 is gonna get anything better then 4800rpm on full boost from what ive seen so far on a evo 8 2L.
