If you are going to use a holset turbine housing the 9cm is the way to go. The problem with that is that most of those have the nasty internal wastegate the make the turbine housing huge.
I guess this is the reason the BEP housings are so popular.</TD></TR></TABLE>

i stated this a bit earlier in the thread i think, but i run a hx35w w/a 14cm2 exh(wastegateless) i start seeing boost by about 4g and get 12lbs by about 4500rpm. this is on a 1.8l ls/vtec w/a stock cam'd b16a head.

 

I just like good throttle response... That is why I usually go with the smaller A/R housings. The big turbine wheels of the Holset allow for good flow on the top end.

 

I want a highway beast and full boost by 6.5k revving to 7k. lol j/k. I'm still looking for a 12cm2 housing. From the looks of it the 9cm2 will die up top.

good throttle response...hell i step on it in any gear and within seconds im at full-song...i just think its pointless to choke down the housing when your already seeing decent spool times...

 

Anyone have a compressor map for the HX40? need a enlarged one where I can see teh numbers. I'm mapping out a compressor map for a motor.

That is why I recommend a 44mm wastegate with the smaller turbine housing. The oversized wastegate will allow the backpressure to come down considerably. I have seen around a 15-25% drop in backpressure in going from a 38mm to the 44mm and the HP went up about 5-10% too.

 

ok found a Holset HC1 Turbo with a 16cm3 for 300 bucks. anyone have any positives or negatives about it?

my 12 cm housing drops off power at 6600 on my ls...with the 14cm it keeps all the way to the 7400 rev limit i had on it...i couldnt imagine using a 9cm housing...

 

really? Interesting.

 

Butt dyno or real numbers?

 

hmm when does it make full boost?

 

Good news, Just bought a 12cm housing for 50 shipped! Anyone want a 21cm housing

i need 12cm pls...

 

which holset turbo do you guys think i should get for a f22b2 accord with pistons and rods looking to get 300 on 15 psi and 400 later on down the line when the engine gets fully built?

the 12cm one please

 

I join the holset thread I got my H1C for $60 now im looking for the info on it lol.

Assy: 3528918
Serial: H-395793
Custoer: 3528918-1-10/0
Type: H1C

 

On a map that i was playing around with. I have to go back and complete the final tune. This pull was at 18psi and the A/F were still in the 10's with 1000cc injectors and excessive timing pulled to be safe.

The lower graph was the run i did at 10psi to give a difference on how much of a power difference there is with an 8psi increase.

Ill post build specs later, but speedave knows me and knows the build. its a LSVtec built, with a Holset HY35 and Trust 50mm wastegate.

until next time...

 

Sry, i should mention that in the civic, shell you can really see the turbo anymore with the way the dump runs for the wastegate, however below is a pic of the stove in my crx shell before it decided to meet a hwy barrier.

You can see the turbo nicely hanging around and having a good time there.

 

What color is that? nice numbers. Another question, Why are you running conservative timing and afr's on a built motor?

 

Here are some pics of my turbo I did the work myself:

 

^^^

Why so rich? I would guess that is really hurting your power. Looks like you did ~238whp @10psi. I did 315whp @11psi and I know that it is a fairly conservative tune as well. No cam gear adjustments made, 3" exhaust w/cat, hy35 as well. Nonetheless, I bet its a fun car to drive.
