Holset Volvo HX-52 Dyno Sheets

[biglady112]

Jeremiah, I used a 4.5" od/4.0" id vband and a 4.5" id vband clamp. I am running a straight 4" pipe out of the fender, so I cannot say much about trying to adapt it down. For the compressor outlet, I got the turbo with the slip on/in hose outlet versus the vband. I did not want to have the thing get here and have it be some oddball vband I would not be able to find with it being a holset. So I went with a 3" 90* Vibrant weld on elbow. AS far as the bolt hole spacing, I just "slotted" the bolt holes in the exhuast housing inlet in a drill press. Oh, and I also turned down the vband outlet on the turbo itself as it was actually 4.7" versus the 4.5" I needed to work properly with my vband ring. I used a large lathe to accomplish this.

I am running a revhard manifold in my application. And just a simple knockoff 38mm wastegate. I ended up not running a spacer that divides the manifold. The person that was suppose to be doing the spacer blew me off again, and after seven months of my manifold sitting down there, I went to pick it up. I am going to run it just like it is. Undivided manifold, divided turbo. Not too worried about it. The 1.6L is going ot spool like crap either way.

And to set the record straight, my friend(the original point of this thread) actually makes FULL boost by 6700. And is seeing boost around 4000rpm. This again, is at 6000ft above sea level. So that means he currently has a 2300rpm window of full power. But the car is moving well long before then.

I got my turbo mounted tonight. The goal is to measure everything and take the intercooler and compressor housing down for welding tomorrow. All my parts came in. Just waiting on the wastegate. That is the last piece.

Biglady can you please post a link to the actual flange and clamp you purchased? I've been scouring the net with no luck. If the GT42/45 V-band flange and clamp would work then I've found plenty of those. I've definitly decided to put the HX52 on. Just need to figure out all the gory parts details.

 

[biglady112]

I just bought a steel 4.5" od ring. It came with two. Was $30 for mild steel and $40 for stainless. The clamp was $10.

It still works with the holset 4.7" outlet, you just have to make it be centered on the turbo. That is why we turned mine down, so when the clamp tightens it, it centers itself.

[Maglin]

thank you for the links. I think I'll turn mine down as well. It does just make it much easier to install the DP when you don't have to worry about centering it up really. Again thank you for the info.

You could make the same power on a 35R at 25psi and get 2000rpms more torque.

The HX40 is comparable to the GT40R in the power it's able to produce with the flow rate being 69 lbs/min, but much better spool rate.

a 3582R HTA flows 75lbs / min and hits 22 psi at 4200rpms (30psi by 4500).

I never did see the hype in these turbos other than you can pull one off a driving brick for pennies and make negligible power compared to something that runs on smaller wheels and boosts sooner (and will last?)

A HX40 is pretty much similar with the flow rate being 69 lb/min and spooling in the high 3k to low 4k on a non stroker block. Furthermore, it is definitely more reliable than the DBB non HTA. Holset specializes in turbos for 7L-15L diesel trucks about half the price of HTA or even DBB turbos.

BTW - Is the 3582R HTA spool rate based on your stroker block?

 

[Boosted98gsx]

Numbers I gave are from previous 2.3 setup (magnus manifold on a 6-bolt stroker with FP3's).

exactly

If any turbo has hype it's the HTA turbo's. You pay out the ass for a turbo that I don't know if you realise this was doing these things power wise even before there was even HTA tech. There have been gt35r's in the low tens and 9's before nothing special at this point in the game and they cost $1600

I don't know where you get your info from but I see you speaking hear say about holset turbo's all over this thread when I know you have never owned one. A hx52 is rated to 90lbs/min so a GT35r even HTA does NOT flow like it and is not in the same league of turbo as a HX52. That's like saying a GT35r and GT42r flow the same

Boys even when these turbos see 10s-9s-8s, theres going to be naysayers. It really hurts feelings when a sub-$1000 turbo flows as much air with an inferior turbine housing and ends up being more streetable.

E.G., no offense to Andrew, but he hasn't even looked at the inducer diameter of these compressors, nor has he let his reading comprehension lead him through this very thread. Thre are already 3 4-cylinder gas motors with hx5* series turbos over 700whp. But his research has lead him to other conclusions.

3582 HTA is 70 lbs/min according to FP specs so you cannot say the HX40 lacks in performance or quality as it flows 69 lbs/min. It spools a lot faster than the 3582 HTA on a non stroker block for half the price.

Thats' the problem is I don't think he has done any by his repeated hear says and false info he spits out about holset turbo's.

A psychological factor comes into play too, he would like to maintain his coolness .

He tends not to believe a penny price turbo could not be comparable to his 3582 HTA in the capabilities nor the quality. But you can all understand that, it happens to every one of us when people say theirs is better than yours.

Aside from that, let's get back on topic.

 

[dsm-onster]

Amen, this thread is not about pushing the hx52.

The hta gt35r flows 28% less, but happens to spool faster with 20% more engine volume and a smaller turbine wheel and smaller critical area turbine volute.

You are extremely close minded Andy. Not every one wants a fast spooling turbo. We need to keep the torque down as much as possible on the salt flats. And we have been there and done that, and plain and simple, a weak ass GT35 is not going to pull 240mph+. And I would rather hit my mph mark in 2-3 miles rather than ride it out for a full 5 or even 7 miles like they sometimes have the course setup for.

So for me it is two things. A reliable and affordable turbo, and a big SOB that is REALISTICALLY going to put my car over 200mph and not take all day.

You haven't given much thought to internet smack talk, have ya?

I'll nut ride my HTA till it dies

 

[Maglin]

I somehow missed how this flamefest started. But just about anyone gets offended when someone says their xyz is garbage. (xyz being Holset atm) I think If I spent like 2K for a turbo and some $400 turbo out spooled and made more power everywhere over my said 2k turbo I would be but hurt. Might even talk out of my hurt butt.

God when I went to an autocross in ND 5 years back I didn't even bring my newly installed HX35 and people where asking me more about it than the very very clean FD3S I showed up in. Mainly cause it was unchartered waters and unproven. And for the $450 I had total in my HX35 it was just fantastic. I didn't totally love it and sold it as it spooled to fast and pettered out past 6000ish rpms. Both issues being caused by the BEP TH.

Anyways stop posting GT35R crap in this thread. Yes we all know it's the total bomb and if we don't go get one right now we will start progressively losing cool points until we are so uncool that we are hot!

So the HX52 is going on the 1G and the H1E is going to have to find a twin and go on my truck.

I have one big question. What BOV are you running on the salt flat car? I have a Greddy Type S that I was going to run with the H1E but now I'm thinking that I would have to go with a Tial BOV. I don't want 2 BoV's and also don't want to run into compressor stall like I did with the HX35 and a modded 1G BOV.

 

[biglady112]

He is running a HKS Godzilla BOV.

I know this is an old post, is this engine still alive? I was wondering if you had ever seen this product....

Seems like it would be the best of both worlds on your particular setup...

[knochgoon24]

He doesn't need any faster spool. The car has to rev out pretty far to hit 220+mph. He needs flow more than he needs spool speed.

I was thinking more along the lines of driveability.... Or in general for anyone with a large dual scroll turbine housing.

Here is alink to a homemade unit. Pretty great results... with this little guy....

My little motor is still very alive. And the above poster is right, spool is not what I need. With running a 4" wide tire(less than 3" contact point) on a wet salt surface does nothing for traction. And me being FWD and weighing less than 2300lbs with role cage and everything, spool is the last thing I need. I do need something that will move the air I need at the high rpm's that I need.

Thanks for looking after me, but the HX52 is meeting all of my needs for right now. I would love to put a Borg Warner S480 on my car at some point though. That would be awesome.

I didn't know if you were street driving this car much. Could always wire the valve open for salt flat blasts.

Great to hear your still chugging along though! I'd like to build a top end monster next time around. Haven't decided on a platform yet though.

Turbodaves.com is having a sale on there s400's. 75mm comp is $595, with the 80mm comp. upgrade they are $849. Pretty good prices!

Good luck, keep us updated.

just got my hx52 and thought id add some pictures of the hx52 16cm housing and hx40 16cm housing
