anyone got one-good points bad points or more info please
thanks

It's a Hybrid based on an 18gram and is good up into the high 300bhp.
Harvey has them and it's one of the one's I'm currently interested in.
I stand to be corrected on some of the points.
I'm starting a related thread which may be of interest.

where is the thread gen tech??

It's in this section, VF34 etc

 

now i see it lol

 

I am searching for a bigger turbo to reach a higher performance at high revs and in addition I am interested to reach the holy 400 hp mark.

My ride is a wrx sti my03 type uk with this setup:

- ej20
- standard internals
- 3" Aerys turbo-back
- Green Performance panel filter
- Walbro 255 fuel pump
- VF35 turbo
- Ecutek 360 hp and 490 nm
- mileage 40.000

The engine runs pretty good but I miss some more performance for better elasticity datas.

Would the ST380 be the right turbo for my intentions? Is it possible to run such a high performance with stock internals and what injectors would be the best choose?

Furthermore I want to know something about the spooling qualities of the ST380. Spools it much slower than the standard vf35 unit?

 

I think Harvey does his own hybrid, the HS380, similar idea to the ST380 tho. Worth getting in touch with harvey because he can offer his headers and uppipe at the same time and you know it all works together well

These 18g based turbos aren't a guaranteed bet to get to 400, I think the 380 in the name indicates what the makers are comfortable expecting the turbo to produce. A 20g based variant would be a better bet for you, like the scoobyclinic SC40. Harvey does a 20g based one too I think. The 20g will spool more slowly than the vf35 for sure, it's a trade off between spool time and power - basically the bigger the g the slower the spool but the more power, the VF35 is like the 16g TD05. The hybrid turbos are designed to reduce the tradeoff, so you get faster spool off one of harvey's hybrids for the same level of power than with the stock model

 

SC40 billet would be my choice for 400bhp too, cracking turbo and actually feels more responsive than the stock VF series turbos in the real world.

You will find it more rewarding to aim for a joined up package that will give a responsive fast road car representing valuue per bhp than aiming for "400"
Afterall, what is 400 on one dyno may welll be nearer 370 or even 430 on another dyno.

 

I am searching for a turbo that will produce a higher power output for improved elasticity datas at high revs. The turbo should also have a good spooling response like the standard vf35 unit at lower revs. Which one you would recommend me, when I don't want to change my tmic setup?

 

just back from andy forrest mapped 320bhp low map and 420bhp high map on S206 turbo-low bhp as 555cc injectors-very nice
martin

 

420 on pink injectors? What F.P. ?

 

out of interest what's the difference between the hs380 and andy f 18g?

 

Not pinks Harvey, Martins Murtaya is on Nismo 555 side feeds.
Nice result Martin, must be very swift in that fantastic little chassis

Martyn

 

very swift even on 320bhp map
