Holset HX52 DSM= 816hp/569tq@38psi

[biglady112]

We are sure the intake manifold is a restriction. We are currently accepting sponsorship offers for a manifold. We will gladly install one if someone wants to cough one up.

I would not say it is slow Paul. Just slower than most folks would tolerate. But if you play in GT42 land it is right up there. We see full boost around 6500rpm like I have said before. Peak torque is around 7500. That is when things go crazy. If I remember Paul, I will try and look at the datalogs next time I am down there. I won't be sharing any datalogs however. No idea on the airflow. This car is a speed density car and it has not been dialed in. This car barely ever is ran, and we don't have the desire to waste our time and money on the dyno dialing the airflow in. This is a true blue race car that rides a trailer everywhere it goes. Not enough time to work on things like that.

I clicked on the link and it works just fine for me. It was edited with Linux software and loaded with Linux software. I run a Linux computer as well. Maybe that is the issue?

It is hard to say what the HX52 could really do. It is all speculation until someone makes it happen. Including us.

This is a Revhard that is heavily modified and is now a twin scroll setup. The Holset is on the factory 16cm divided housing.

The dyno was set for a different gear on the 210mph run. That is the reason for both the MPH and RPM being off. Once we got over 8700rpm or so every time the dyno RPM read out would be different. Not sure if it was a setting or the dyno just freaking out, but up to 8700 it seemed to read pretty close in 4th gear. And we made peak power at 7500rpm.

I wanted to host the dyno sheet on photobucket but gave up. I just attached the PDF in the first post.

Any pics of the exhaust manifold showing how it was modified?

 

[biglady112]

Nope. He has them, but I doubt he will share them.

 

[rr06rs]

Why so secretive? Lol!

 

[biglady112]

Why so curious? It doesn't matter. It is divided and that is that. I run the same turbo on my truck with the same manifold. But I left mine as it was and run it undivided manifold/divided turbo and we are pretty close for spool.

He is just that way. And I back him. I have given more than enough info. No rocket science behind the program. Against the grain maybe, not nothing you couldn't whip up on your own.

 

[LxiMax]

Wow, that's all I can say! Amazing build!

I never said it was anything like any HX40 you tuned because if you had the ability to make an HX40 put down those kind of numbers then your HX52 numbers would be higher. I am just referencing the 700whp HX40s we have running around on AWD platforms. If you do the math of an 816whp FWD it would be calculated as right around 709whp on the HIGH side and 685whp on average. But then again you can calculate the 12-18% drive train loss how ever you'd like and then put a search in for what HX40s are putting down being tuned by some of this known people/shops and you'll see they are at hat number and higher.

Just for the record, how much power did you expect him to make on 110 and through a stock intake manifold?? When you have never done it, it sounds way easier than it is. Actually put down some good numbers track or dyno, then go around talking about how much different they are than yours. We all wait to see what the self proclaimed guru can put down with his 52.

Also, where did you come up with that math??

This was also not done on a dj, which is where I'm sure your 40 numbers came from.

Props on the power. Anyone should be able to notice a lot is left on the table. Good luck on the mile!

 

[biglady112]

110 octane is not limiting us. Just want to put that out there. This car has run on 110, 112, 114, C16, Q16. It pretty much runs about the same on all the fuels. As long as there is lead in it, it runs just fine.

 

[uncle ben]

I seem to think some people base all numbers off other numbers. The reason I mentioned the gas is because id say 90% of all people making over 900 have moved to eth, meth, q, or import. Id like to hear some other high power 110 dynos. Id also like to hear some other high power stock mani cars for reference. I'm thinking this is one of the highest, if not the highest ive seen.

Nothing you said has any relevance juxtapose to the discussion we were having.

I simply stated that that setup has more in it and he and everyone else agreed upon it. Other than that you are stating stuff that even people with basic automotive knowledge could have figured out.. I can't tell you what type of dynos the other numbers were done on and neither can you so its speculation. The HX40 6/7blade billets are mechanically large enough to post 650whp+ numbers on even a Mustang and I sure hope that isn't what you are impying...

Also What math are you asking me about? You mean the basic ability to figure out percentages? Or the known fact that FWD to AWD is anywhere from a 12-18% drive train loss. (I am sure you can do the basic math to get to the numbers I posted)

Rofl, you have got to be kidding me with that asinine post.

Either way, great numbers as we have said and at 38psi and the setup it has it is only obvious that car has the 150+whp left in it as I mentioned earlier.

 

[biglady112]

We think this is the highest we have seen as well for the stock intake. We did not intend to shoot for any potential record there, but it has just worked out that way.

Once upon a time when we lost a fuel pump when it had a dual pump setup we had Q16 in the tank. I am certain it is because of that fuel we did not lose the motor. Granted his EGT warning lights came on, but it was slow enough he could react to it. I still think that a DSM can make 1000hp no problem on gas. A few folks have done it and are in that area on gas.

As far as 150hp more, that sure sounds like we are asking a lot of this little Holset. It made over 800. Not sure how far he wants to push it, but if we decide to stick with this turbo when we move to a streamliner, we will surely see what it is worth then.

Well that is very ineresting. Assuming you guys simply added a straight divider inside the collector, it's dividing 1/2 & 3/4 instead of the known firing groups of 1/4 & 2/3. I assume running the manifold open and unmodified wouldn't be any less performing that the way you guys have it just for that reason. Have you guys tried the manifold open, or has it always been divided?

Its made great power as is but your setup alone shows the true potential of what this turbo can do. Everything from your Manifold choices (Intake and exhaust) Your rod/piston combo, cams, your fuel choice and even boost levels can all be GREATLY improved upon. I think you guys have shown that this turbo can be a MONSTER on a full all out setup.


Regardless of that you guys will be halling ass and taking names I am sure.

shhhhhhh......it's a secret..... Lmao!

 

[biglady112]

His has always been divided. Backwards from normal thought process. It was more designed around the wastegate hole than the exhaust pulses. The car has rock steady boost control with a old school 38mm Tial. The wastegate hole is divided as well.

We run my truck with an undivided manifold and stock holset divided housing. Like I said, it is pretty close to the same. We also run a Mirage with a S366 with a knife edged .91 housing and an open Revhard manifold. The all spool in the 6500-7000 range for peak torque.

Hea, we have to ball on a budget. He is a part time systems administrator, so only so much cash to go around, thus why we build and make everything in house. He even does complete start to finish cylinder head repairs, porting, seats, guide work, resurfacing. Start to finish. He purchased all the tooling last year and it has turned out to be a great thing as the quality control is now where it needs to be.

Like I said, we are always accepting sponsors for parts. If someone wants to supply something, or is willing to give generous discounts, we will entertain them.

I never said it was a secret, Paul just used his imagination like I told you to do.

 

[dsmdeliveryboy]

Crazy numbers, I have basically the same motor setup. Cool to see what you can throw at it.

 

[bastarddsm]

Did you change the pairing of the cylinders or is it done the easy way, 1&2 3&4?

 

[uncle ben]

Thats funny. Good way to deny ever doing anything worth talking about though.

I simply stated that that setup has more in it and he and everyone else agreed upon it. Other than that you are stating stuff that even people with basic automotive knowledge could have figured out..

No, actually you came in his thread trying to downplay his numbers. Saying they were no better than peoples 40 numbers if you took out the fwd factor. I thought people with basic automotive knowledge could understand you arent going to make 1000+ with a stock intake, yet you still felt the need to come on here and tell him how his numbers were low. Low for what? A keyboard warrior? If you would think before flapping your gums you would have realized its probably a record for a stock intake. Id say thats pretty dang good, and personally thought it was border line retarded for you to come in here with that nonsense.

What I do love is how you have changed your tune. Now your the nice guy that tried to say he just had more in it.

I can't tell you what type of dynos the other numbers were done on and neither can you so its speculation. The HX40 6/7blade billets are mechanically large enough to post 650whp+ numbers on even a Mustang and I sure hope that isn't what you are impying...

Actually I can. Here is some links for you so you can see all the high ones were done on a dj.

620 evo dj 620hp~ Evo VIII stock block E85 HX40@37psi - evolutionm.net

Those were off the first two pages of google. The highest md number i saw was 575.

Just to be fair, you are more than welcome to show me a 650whp md dyno from a hx40 powered dsm. It can even be a high compression eth motor. Since you like comparing the two anyways.

Also What math are you asking me about? You mean the basic ability to figure out percentages? Or the known fact that FWD to AWD is anywhere from a 12-18% drive train loss. (I am sure you can do the basic math to get to the numbers I posted)

Show me some proof of this known fact. Ive owned dsms for 12 years now, and never heard a difference of 18% between a fwd and awd. You might want to shoot for more like 10%. We are talking manual to manual here. Not manual vs auto. Even being, apples to apples man. Show me some hx40 numbers with a stock mani and not on e85.

Rofl, you have got to be kidding me with that asinine post.

Here is another funny one. Everything that comes out of your mouth makes me feel that way. You have been thumping your chest on every dsm forum, yet nobody has yet to see you prove anything. Stop thumping your chest and get out and do something. Show us what the hx52 will do. Let me show you one more time what i mean. You remember saying this?

I never said it was anything like any HX40 you tuned because if you had the ability to make an HX40 put down those kind of numbers then your HX52 numbers would be higher.

So because the stock mani'd car only put down 800+, that means he couldnt do a high compression e85 motor and make 680 with a 40. You were taking stabs at him because the STOCK MANI'D car put down 800+! I mean its probably only the record for the stock mani, so I can see where the stab would come in.
Since we all know you have the ability, PROVE IT TO US!!!!! Show us how much more you can make on a stock mani. Almost everytime i see you post, its trying to down someone. No matter how many times you try to act like you know so much and could do so much more, not a sole will believe you till you actually do it!

Either way, great numbers as we have said and at 38psi and the setup it has it is only obvious that car has the 150+whp left in it as I mentioned earlier.

Great numbers huh?? I thought they werent any better than all the 40 numbers you know? You seriously need to make up your mind.

 

[StarFawkes]

Stock intake manifold

This is what amazes me.

 

[DSMReviver]

First of all Congratulations on that big number!

Did i hear you say you are running a stock OEM valve springs and you are revving it to 9,000 rpm and with aftermarket cams?
Sounds like something is gonna pop soon and the springs are just dancing around in there.

 

[biglady112]

They have been set to a specific install height. We ran a Mirage last year to 9250rpm with stock springs at stock height. I have been doing 8500-8750 on stock springs at stock height since 2006 on the same head.

This is the 5th year on this particular car, so I doubt we will have any issues any time soon. What you don't understand is he has a small cam, so that is how he is able to get away with it. The two above mentioned cars do have larger cams, but we have no concerns.

It is all in the setup.

What happened with the Colt? Is that going to be ready this year as well?

 

[biglady112]

The owner of this DSM is now the owner of the colt. We are going to finish it as a naturally aspirated project. Going after some Honda records. I took the entire setup out of the colt and that is what is now in the truck.

 

[Scoobystyl]

Awesome numbers, have you ever thought about building an intake manifold?

 

[biglady112]

Truth be told, we would rather build our own than use someone elses manifold. That is the good part about having the skills and equipment to do so. But for now it will stay and we will just go through the last of what we need before Bonneville and run it as is.
