Default Blouch TD05H-18G 8cm^ Turbo Installed! (With Pics)

Just finished the install...Preliminary road tune with ST...Feels very strong at 20psi!! Protune will happen May 18. Looking foward to feeling the power after the tune!

Mods:
Blouch TD05H-18G 8cm^2 (TD06 Compressor Housing)
APS DR525 FMIC
APS CAI
APS Turbo Inlet
APS Twin Vent BOV
PE800cc Injectors
Walbro 255lph Fuel Pump
NGK Iridium 1 step colder
Prodrive Boost Control Solenoid
Cobb Uppipe and Turboback Exhaust w/high-flow cat

Tuning Update:

The first round of tuning has been done on this setup with a conservative map. The car is very smooth and pulls very hard all the way to redline. Matt Holland (ShaggyGT on here) did the tune and did a great job! Great guy to work with as well.
93-pump gas tune: 310whp/278wtq - mustang dyno It's so smooth it feels like it does this with little effort. We think there may be a little more to gain with another round of tuning. I may revisit that as well as a race-gas tune.


Spooling (3rd gear pull - 5mt)
16psi @ 3300rpm
18psi @ 3500rpm
20psi @ 3600rpm
21psi @ 3700rpm


It's awesome!!










Stock TD04 on right:

So what does the larger housing do compared to the regular housing? More top end at the cost of slightly more lag?

The OP has the standard 18g. Yours is a 16g with an 18g wheel.

TD06 is the code for the turbine housing, not the compressor.

No...

TD05H is the turbine wheel
18G is the compressor wheel
TD06 is the compressor housing
8cm^2 is the turbine housing

Blouch indicates this particular turbo uses td06 18g wheel in a td06 compressor housing.

Blouch also states the td06 compressor housing maximizes compressor efficiency. Whether or not that is just marketing -- I don't know. I'll be seeing the numbers soon.

i haven't seen a lot of downsides to larger compressor housings. perhaps (when you get really big) interference with tgv or bellhousing...

Were your vacuum connections on the blouch different from the OEM sizes?

I just installed a Blouch 20g and mine were way off. I'm still trying to figure it out because with all the reducers I have on mine, I'm not comfortable with it.

Ken -- thanks man, that's good to know. With this housing and the APS turbo inlet, I had to modify the uppipe brackets and uppipe to get it lined up correctly. The turbo housing is almost touching the bell housing and I had to grind a little off the turbo housing to clear the breather tube that comes up from the engine block.

Anything larger and I'd go rotated mount.

Same here man! I'm still trying to get this sorted. First thing is the stock boost control system will not tame this turbo. I'm sure it's the restrictor pill that needs attention (too small for this setup).

I'll have a prodrive 3-port boost control solenoid in hand tomorrow and will work out the vacuum lines and any reducers once I have the part in hand. This gets rid of the restrictor pill issue completely.

In the mean time, I'm running wastegate spring pressure (15psi) with a line running from the turbo compressor to the wastegate actuator. My first attempts at tuning this turbo with the stock boost control solenoid and Street Tuner got me 23psi with 0% WGDC. And the boost would have kept on going if I had not let off . I knew then I needed to change something mechanically.

I'm glad I wasn't alone

I'm going EWG and looking for options for another boost solenoid so I'm hoping to bypass all the stock hoses, pills, etc.

How about your upper coolant line on the turbo? Mine is an extremely tight fit and the rubber is sitting on the housing. It's not leaking but I really don't like how it's sitting on there.

Besides that, this thing is beautiful. EWG and a tune and I'll really start ranting about it.

Yeah, my upper coolant line was tight, but not touching anything. I thought if it were any tighter, I could trim it a bit for a better fit.

I agree -- this thing is a beauty. It was pulling crazy hard at around 22psi! Just need to get these minor issues sorted and away we go!

Maybe I'll try to find a smaller OD coolant line for it. Seems like my only option.

Glad to see someone else with a Blouch Rock on! Make sure you post up after your tune!

Thanks guys! I'll post up the tuning results.

b0dh1: I helped a friend install a Blouch Dominator III on his STi in Feb. This is the one with the 52 lb/min wheel. The thing is a real beast -- almost scary When you hit it the turbo screams as you are thrown back in the seat.

I'm stoked that I keep hearing great things about Blouch. The best part (for me) was when I started searching for one, I wanted it right away. I called alot of vendors and everyone had a 3-4 week wait on all 20gs. Mike at Blouch had it ready in 2 days. Weird huh?

What exactly did you have to do to make it fit on the up-pipe? Is it aftermarket?

Mine lined up just fine. It just takes some wiggling to get it in.
That was with a stock uppipe. Ill tell you about how it fits on an Invida on Saturday.
