FP Green/FP2 vs HX35/Kelford272

[thilaksharma]

I finally dyno'd my car , the previous setup is in dotted lines

Old setup
FP Green with 7cm housing
1G stock block
Stock 1G intake manifold
MMLS 1.2mm
1G head with FP2 cams
Boost 32psi , 93 Octane fuel

New setup
HX35 billet + FP30 turbine housing
Kelford 272 , TX version
Boost 23-24psi , 93 Octane fuel

I can trully say, the HX35 is a 50trim with steroids, im getting more mid and similar power with much lower boost. The car was run on a Dyno Dynamics dyno which is known to give 10-15% lower hp than the dynojet.

Very solid numbers for pumpgas and such low boost on a holset. Seeing as how they love being run in excess of 30psi making 350+ at 23 is really respectable.

I"ve got a question for ya though. I have a customers' hx40 here and a GT35 turbine housing and am machining them to work together but being the shallow volute on the 35 housing i was working to machine an adapter ring to get turbine placement correct. I was wanting to know if you used an adapter ring or if you just machined it open enough to fit (the opened volute will work either way it seems but i've heard of people running the ring on similar hybrid jobs on the holsets) any info or pics would be awesome if you're willing to share them.

That's awesome! Love, love, love to see comparisons like this.
VERY impressive to see what the Hx35/Kelfords are doing at much less boost.
Now if you can only do a run at the same 32psi, we can really see what that setup can do! Thanks for sharing

X2, how did you get the FP housing on the Holset?

dnt take the FP30 housing, FP offers another housing called the FP30 Style housing for a Stage III Garrett T series turbo , u just need to machine them for about 2mm and u r done , the GT series housing will cause much much more fabrications

warning, the HX40 wheel will not fit , you have a very minimum of xcess meat on the casting for you to machine

I was looking at their housings, and figured it was this one:

Forced Performance Turbochargers: FP30 Style T31 Turbine Housing


Very cool stuff indeed.

the HX35 is a 60/70mm wheel
the T31 is a 56.5/64mm wheel

so you do need an experience machinist to do it. I am from Asia, so I can source it out for you guys.
