Holset Turbos, PART 4

[jkimes]

what is the part number for an hx40 with a billet wheel, 60mm inducer, and 19cm hotside?

You have been looking for a turbo for way to long man. Now your getting way too specific . I haven't seen many hx40's with billet wheels but I know the exsist. I would just look for a hx40 with a billet wheel then worry about the hotside later. You can pick up a POS turbo with the hotside you want for like 200 on ebay and just use what you need.

I had a chance to take apart the HE351VE my friend picked up. I used some clay to measure the minumum nozzle area with some clay. I definitely found out why it spools so quick and muffles the exhaust so much. It closes down all the way to around to somewhere between 3-4cm^2 my best guess at the right measurement is 3.5cm^2 nozzle area. Its so small of gap, around 1.5mm gap, with the soft clay its hard to measure it 100% accuratly.
So its variable from approximately 3.5cm^2 all the way to 25cm^2.

You can see how small it gets.

Can everyone who runs a holset post up what rpm they spool at. I think that it will help many people, including me. Thanks Guys

Yes it is a 2.4l. 8-8.3:1 compression.

Here were my initial spool results with the VGT rack fully closed and fixed there. This is just the first log I opened.
Here are the the most important things affecting spool

I can't remember what gear for sure but I think its 4th.

8" of 3" pipe for an exhaust
No intercooler
E85
8-8.3:1 compression
stock head, cams, intake manifold
Fairly low timing
1800 1psi
2000rpm 3psi
2500 8psi
2600 10 psi


Its a little slower now, the actuator starts to open the thing up a little sooner than I'd like.

Keep in mind this thing has a compressor in the GT35R size class.

Holset h1c (flows as much as a 50 trim)
fp2x cams (laggy like 272s)
3" turboback exhaust
ebay tubular o2 housing
stock-style evo3 exhaust manifold
stock head
stock intake manifold
ebay fmic (20" X 9" X 2.5")
2.5" short route ic piping
2g maf
3" intake
K & N

3rd gear: 10psi @ 3000rpms, 20+ psi @ 3400rpms.

All these pages and i think there is only 15 ppl on this site running a Holset including me

I have a Holset H1E on the car, but the car does'nt run, in fact the car has'nt left the garage since putting it on the car. Someday soon.......

I have an hx35, but im still trying to get all my supporting mods.

 

[andy4g63]

Holset H1E, all mods in profile
T3-0.70 AR hotside
BC 280's
JMF Race IM,etc.
20psi @ 4800 RPM/3 gear.
Starts building boost at like 3500 RPM.

 

[420a-t]

Holset H1E
.55 bolt-on housing
Comp 101100/101200 cams
JMF SMIM
1g TB
Apexi Skyline FMIC
3" downpipe-back
stock compression
etc...

I get full boost (22psi) around 4200-4300rpms

Is the above too much to swallow? . . . In simple terms, the hx35 may flow as much an FPred but still of course spool faster than an evo3 16g; all the while with much higher efficiency at high boost. We don't know for sure of which compressor wheel holset gave up the above map. I'm leaning toward the 7blade 56mm wheel. There is a significant difference in flow between compressor wheels with the same inducer diameter, but less blades. The hx35 has an 8blade compressor wheel and a 7blade compressor wheel.

So you believe the 7-blade flows the most out of the HX35's? I have a 56mm 8-blade and a 54mm(? i think) 7-blade. Which one should I run?

 

[winterftbl]

thanks alot for the replies guys, keep 'em coming.

 

[turbotalon1g]

Good replies, any dyno numbers on what kind of dyno and also 1/4 times.

 

[420a-t]

My buddy made 575fwhp with his hx-35, .55 bolt-on housing. this was on a superflow dyno with 28psi and a 75 direct-port shot.

6 bolt
hks 272 cams
air-water intercooler
AEM EMS
3" downpipe
SMIM
etc...

 

[JWoodley]

My dyno results are under my username on a bone stock 7 bolt motor.

Did you get this h1e from goldfarb and associates? What part number do you have. I have an h1e and I was wondering if the spool would be similar to the hx40. . . Looks like it is. Were you the one who bought the same h1e as mine?

So you believe the 7-blade flows the most out of the HX35's? I have a 56mm 8-blade and a 54mm(? i think) 7-blade. Which one should I run?

It's possible. I don't know all the wheels for the hx35. I thought for sure that there was a 7blade 56mm wheel for the hx35. . . I have to look through my notes. It would be very exciting to have the spool of an hx35 but the flow of a 60-1. I'm not sure if the hx35 turbine wheel in the bep housing could push the limit of such compressor flow. But I can see the possibility with a good divided runner t3 manifold, stock holset turbine housing, and a wastegate dump tube.

 

[420a-t]

Yessir, I got the same one as you. We talked in the the other holset thread...but it was like a year ago . I have this turbo on my automatic, and I just installed a nitrous kit to help for off-the-line stalling. We'll see how everything goes...

 

[AXRabbit376]

I thought for sure that there was a 7blade 56mm wheel for the hx35.

There is a 7blade HX35. I can even give you the Cummins part # if you'd like.

Anyone know which HX35s came with the Ti compressor wheel option?

Also, you guys are saying the it spools faster than the E316G, is that with the BEP housing or the holset? I would rather run the Holset, personally.

 

[95tzlgst]

thats with the bep .55ar

 

[turbotalon1g]

How would a HX35 in a bep bolt on housing with a T04B cover act? wouldn't this smaller cover limit the power potential?

u wouldnt take advantage of the extended groove then

 

[ludevtec93]

do they still sell these BEP housings? i cant seem to find any.. and do you guys know where i can pick up a hx40 for fairly cheap besides ebay?

This should help out with spool a little on my hx52 Funny part is though I have no idea how the hell the fuel rail would hook up

That thing is funky looking. Did you make it? Or what was it originally made for?
