This was me, Made 494hp 466 ft.lbs on a Mustang Dyno. 7 Blade HX35 with standard 12cm T3 Hotside. Here are some specs on the car.

91 AWD talon
Wiseco 9.0/1's
Eagle Rods
Stock 1G Head Ports w/ crower valve springs
FP2's
Stock intake manny
Twin Walbro 255's on E85
PTE 1200's
Keydiver chip
ACT 2600 w/ Street Disk
Gen 2 MAFT with LS1 Maf

Boost was set to 35psi but fell to 31 due to some boost leaks Im sure. We only did one run cause the street disk started slipping at 5800rpm with the power still on the rise. There was a vid of the run, Im waiting for it to be posted on our local boards and I'll copy the link over. Overall it feels really solid, Im loving the Holset. 500hp on the Mustang should be in reach after a clutch swap.

Good job man, i had to leave for daughters soccer game but just saw the video on our local site.

Anyone know the specs on the hx55 compressor cover? I'm looking to upgrade my compressor cover to something with a bigger vband hook up similar to the gt42r and I looked it up the 52 and the 55 have the same compressor cover clamp which means they should be interchangable. I would just have to find one that was set up for a 67mm wheel or smaller.

Heres a link to some of the runs, audio is bit messed up but I'm the first run. You can hear the clutch slip at the end of the run.

Well Im the proud new owner of a HX 40 6/12 blade!! T3 turbine housing. Not sure what it came off though think a bus. hahaha The turbo spins freely and has no end play. Needs a bath!!

^^^Is that a 56mm compressor or a 60mm compressor?

Incredible! Mustang dyno at 18% difference puts you at 580whp with the industry standard dynojet and your trapspeeds will calculate out to a dynojet number. So you're looking at a VERY fast car there. And on a slipping clutch


Sean, Call a good diesel turbo shop, like PDR or Gillett. They SHOULD know how to help you. . . especially if you promise to give them business.

Wow, I thought the mustang was only 8% lower than the dynojet, disk is coming soon so I'll put it back on the dyno.

What would be the difference in flow? If it was a 56 vs 60. I know the 60mm can flow 69lbs. 56mm and 6blade? Here is where I got the turbo. http://ohiotruckparts.us/n/n.html Now it says that it is a T3 by looking at the flange it is a T3. I didnt know that the t3 comes in a 18cm. I thought is was 16cm. Now it is a 56mm wheel which is the same size as the hx35 but has the bigger turbine wheel. What do you think? was this a bad investment? I didn't know there was a 56mm 6blade. I looked on the summary and it said 7/6 blade was the 60mm wheel. So i thought I was getting the correct turbo. guess I should have read all 30 pages and did my due-diligence. Well to late now its going on the car. Guess I will let you know how it works. When I get the turbo I will measure the wheel to be sure.

From all of my personal expereince with different wheel sizes. And from all of my personal knowledge of fluid dynamics, it appears that the 56mm hx40 flows about as much as a 7blade hx35, based its fin shape. And that's about as much as the 58mm 8blade hx40, which has put down some GREAT numbers. 139mph actually.

Can somebody help me with a part number?

The reason I ask is I have a friends who works at Cummins and he is able to get me a Holset turbo, although I have to give him a part number.

I am interested in the 8 or 7 blade HX40 and HX35, with the billet wheel. I will be using the stock Holset divided turbine housing as well.

If somebody could help me out that would be much appreciated.

This was my 7-blade HX40 with a 16cm divided T3 housing:

Well I canceled my Hx40 order cause it had the 56mm compressor wheel. I picked up a dodgezilla hx35/40!! Looks like Tim G is having great results so I hope I have the same. Going to pick up a turbine housing from jusmx141 and run a 12cm divided T3

I have the 56mm 6blade/12blade billet hx40. So is there any benefit of running a 56mm 6blade hx40 over a 6blade 60mm hx40 - for example faster spool, transient boost response? Im sure I will be content with the power since Im only shooting for low 400awhp myself, but faster spool out of this hx40 would make the 56mm more desirable in my case.

Just wondering, I plan on running an hx35 turbo, but I would like to keep my stock drivers side fan, I already have a slim fan on the passenger side and didn't want two slim fans. Now the only option I see is running wastegate off the manifold. I was thinking of using the hx35 twin scroll T3 inlet, using the punishment racing T3 manifold:

Budget Eclipse Talon T3 T4 exhaust manifold

It will work right?

But what about the o2 side? Not sure where to find that? Can someone please help me? Or is there another alternative? Thanks!

Lower number of blades, makes the efficiency and flow at the compressor more of an on/off switch. The 6blade 16g turbos are famous for that. The flow isn't there because the blades are few until the velocity at the inlet matches/fills the blade spacing volume, then boom sudden boost. You SHOULD have a similar feel as a BIG 16g. Hard hit. But it will probably spool about the same over all. Meaning the 8blade wheels will start spooling earlier, but both will see decent boost 20-25psi by the same rpm. The 6blade should be more "fun" if you're willing to tach up a little bit higher than what you would with 16g, so that you can get that 'hit' feeling.

From my observation, the 8blade spools faster than the LARGER 60mm 6 and 7blade. Although I've seen 2 or three 60mm setups show 20psi by right on 4K, most do it by about 4200rpms.

I have an HX-35, 7 blade in the bolt on housing. I was wondering if anyone has tried this turbo on an automatic yet? If so, please share your experiences.

I want to put it on, but I am worried it will be too laggy for the automatic. I am currently running a E16g with a 20g wheel and get 1 bar at 3500rpm and 20psi by 3700. I run a 9:1 engine with 264's. What can I expect if I run it? Same spool would seem to be out of the question.

Thanks in advance.

If it's going to be as cold up there as they're forecasting for Western PA this Saturday, you're in for a real treat traction-wise! I think we're looking at 38* for a high.

You'll have to rig up some sprayers that blast traction compound on the track as you roll up to the line.

Yea numbers and spool times etc on paper arent as promising to the butt dyno as is the actual "hit and feel" of the car. That is what Im after, while still being able to crank out some good top end flow, at least enough for 400awhp on 93 octane with my mods.

That turbo will DEFINATELY meet your goal. And you'll have alot of room to grow.

can somebody point me int he right direction or just have the answers and give them to me ..

I have a volvo HX40 I bought from timsturbos

it has a non-devided bep t3 exahsut housing with a vband turbine outlet... what size vband is that? I am 1000 miles from home so I just can measure it.

also If I wanted to feed the turbo from the head what if any restrictor would I need and where could I purchase said restrictor?

The compressor housing is also vband on the outlet, does anybody have the size on that so I can make sure I have the parts when I get home to start fabbing.

last question, is there any good bolt on return line fitting that does not choke the return hole in the center section?

sorry for the questions but I am working 7days a week 12+ hours a day so i dont have a lot of surfing time..

thanks

1. Some of the HX40's are are 4" exhaust outlets and some are 3", Hard to say which one it might be. T4 housing I would say 4", Being a T3 I would guess 3".

2.I dont think you'll need a restrictor feeding from the head, as the oil pressure is already much lower than the OFH.

3.Compressor housing vband should be 2.5", or you can grind off the flange some leaving a "bead" so you can put a 2.5" silicone coupler on, or weld a 90 degree alum elbow. Fitment will tight against the front motor mount (1G). Stock Fan will be in the way.

4. FP sells a good T3/T4 oil return with a stock mitsu oil pan flange.

I would agree, lets just say it will surprise you. 400whp should be in reach easily.
