Did anyone buy it new from fp with the 9.0 housing like mentioned on their webpage? In have a 10.5 and I wanted to get a good idea of torque from a dyno graph and not speculation like 200 rpm sooner etc..

 

I have the 10.5 hot side on mine I think I lost my dyno sheet but I made 362 tq @3666 rpm

 

I would try a 9.8cm hsg. That should reduce spoolup by a couple hundred RPM. The 9.0cm housing is just way restrictive on the top end. I ran a 9.0 on an OS Green for a bit but ended up pulling it off. I still have the thing under the bench, Ratty, if you wanna try it. But, 9.8 would be a better compromise, IMO w/o trading off as much top end.

EDIT: Sorry my bad. I had forgotten, but I think that the OS Green had a larger than stock turbine wheel, so my 9.0 hsg. is cut and won't work in conjunction with the 71 HTA's smaller, stock TD05H wheel....Duh

Regardless though. I would stay away from the 9.0 and just try the 9.8 instead.

 

Why does this turbo come with a 9.0 cm housing? If my memory serves me correctly, I have never seen it written explicitly like that before until now.

I would contact FP to confirm.

 

Similar to why the HKS turbo came with a 9.0 housing... response.

 

I'm just lookin to see where the 9.0 would put peak tq .

The 71 flows more than a os green I believe ..

Sparky do you know if you can buy new 9.8's?

 

Contact FP and tell them you just want to buy the CHRA and that you will use your 10.5 hot side. Also get a Evo ix waste gate and j-pipe for the install if you are doing this on an viii

 

already have this turbo .. I also had an os fp white clipped.

The <10.5 housings are what I'm interested in for this turbo

 

FP has a couple 9.0 housings in stock but no 9.8 housings.

 

Does single flapper or dual flapper matter?
