Holset Turbos, PART 7

[joyfil2001]

It's more of a jet taking off feeling. You know you're moving and it just keeps pulling.

I disagree, but maybe because I'm auto. For me it kicks in hard right about at 20psi. However, if I brake boost it, you will lose your stomach!

Stock stall? My only tranny mods are the shift kit and new end clutches. I keep leaning toward getting one, but then I get unsure. I really like my 16g though, and my 14b for that matter. I guess I'm just going to have to push those as far as they can go first.... just to be fair, before I switch.

Ultimately, what does the webbing do for me?

I've heard the HX35 is a loud turbo (spooling, etc) and I want to have that with whatever I get.

The webbing does nothing unless there are ports all the way through. the 54mm h1c has the webbing the 56mm wh1c has the webbing. The wh1c has ports all the way through to the compressor blades. I was stating this so that you don't grab a 54mm h1c thinking it was a wh1c with the bigger compressor. Still the 54mm h1c flows around 49lb/min. That's on par with a 50-trim or 20g. The wh1c flows 52lb/min.

Stock rebuilt stall. The lag doesn't bother me too much because it's fun to play catch up (when I don't brake boost). It pulls real hard. I used to have the FP18g and it spools very similar.

Just curious if anyone has some results of running the hx35 with no intercooler just a hotpipe to the throttle body with a water meth injection setup. If so ccdan you post up some pictures

i found more holset info this entier forum is almost all holset.
A nice read. Great general Holset info everyone

lots of cool stuff on this site

You mean spool speed is similar right? Hows the "hit"? compared to 18g? Never been in 18g, I assume it is like evo16g but pulls all the way through the band?

 

[dsm-onster]

The td06sl2 18g (FP18g) is different from a td05h 18g and they will likely "hit" different on the same setup. My td05h 18g "hit" like my 16g.

Why so interested in "hit"? I lost traction EARLIER with the hx35/h1c. That tells me it was pulling harder earlier because VE was up earlier since spool speed was about the same, and the logs back that. Having the power come in a little later so as to have it come on all at once isn't as productive. As you can see by the logs and experiences the power down low is there.

Here is a dyno of the hx35 I think you 've already seen showing over 400tq before 5K. And goes from 200-400+ in about 1K rpms, pretty hard hitting. This is with a SMIM upgrade as well.

That first post sounds awefully familiar

. . . WTF they've copy/pasted a whole bunch of what I and other's have contributed here about holsets.

I've pointed that out to them several times. Most, if not ALL the info there, they've taken from others off the net and given zero credit for where it came from. They continue to blow it off and post it up as their own.

Wow that's wack

Yea I saw that, I just love the "hit", maybe the other turbos I've rode in, "hit" that hard because they had cams, I heard cams have a lot to do with it as well.

Just wondering what turbos have you ran?

 

[dsm-onster]

Ball and spring MBC makes, spool slightly faster, maks the boost spike, then settle at a slightly lower number. While the same turbo running just off a higher spring tension gate that would cause the same final boost will not have the spike. That could make your "hit".

The 18g and 16g I ran hit harder with the stock cams than with the fp2x cams I now have. The 60-1 I ran had terrible spool characteristics for the power potential. BEP bolton with a t31 turbine wheel. I managed 52 lb/min out of it before it blew.

 

[jjrock5]

Can we stop placing quotation marks on the word hit?? It's distracting me like a mofo.

It's almost like when ppl say "um" after every three words. You start counting them after a while.

My explanation has gone long enough.

Yea I know what you mean about MBC.

So your 16g/18g hit harder with stock cams? By Hit I mean pull harder, if that makes sense. So I do not see a reason in upgrading cams if that is so on those turbos

I guess I will see once I get this hx35, sooner or later, but I do plan on getting it as no one over here barely runs them

 

[imdrax]

Not for my DSM but you get the idea....

That looks new! Can't wait to get my holset, I will put it to the test

Let us know how it spools, "hits" haha, etc.

Stock cams caused the motor/turbo/setup to hit harder. REALLY pull through a narrow rpm band: 3500rpms-5500rpms; felt like a "hit" or kick in the ass by king kong or something. Then it fell flat higher. You don't see a point in cams if you just want a feeling of a hit and not a serious power increase. It's not like cam upgrades arn't proven to net significant gain through out large parts of the rev range.

yea that is what I want to feel a huge kick in the ass by king kong haha. But with cams, you would still feel that hit, just that it will last longer as the range will be larger no?

Get in a big turbo, big cam car and you will forget all about hit, as it feels like zeus has a rope tied to the front of the car pulling it. The torque surge in my e-85 16g car feels great in 2nd and 3rd gear. But, the shortness of the powerband becomes apparent when running beside a long geared n/a car.

Yea that is what I mean, I call that a hit? I been in those cars and that is what I want to feel, which is why I'm asking if this hx35 will feel like those other big turbo such as 50 trim, fp3052, etc?

 

[jrohner]

I think most of us think of hit as the strong surge of torque when you first hit full boost, not really anything to do with hp or a wide power band.

+1
Thats definitely causing all the confusion.

 

[viperlp01]

If you want a loud turbo you need to have the woking webbing.. The silencer ring blocks that webbing off so to get the turbo loud remove the silencer ring.. My buddy has a h1c without the webbing and the turbo is soooo quiet..

 

[dsm-onster]

Some holsets have the webbing without the porting all the way through to the compressor blades. Like my h1c. VERY quiet turbo, but has the webbing

The hit business has nothing to do with any thing. The bolton hx35 will pull harder than a 50-trim earlier given the same setup, bottem line. It spools faster and flows every bit as much through the turbine and more through the compressor at a higher efficiency.

First you were wondering if the hx35 "hits" like a 16g, then you're wondering if it hits like 50-trim or fp3052 . The 50-trim and fp3052 have different spool characteristics themselves and both are different from an evo3 16g.

I think most of us think of hit as the strong surge of torque when you first hit full boost, not really anything to do with hp or a wide power band.

I agree too. The 16g starts spooling slightly later than some turbos and comes onto full boost earlier vs. such turbo. Like even the 50-trim. or td06h 20g. Or fp green (VERY similar). This makes a sudden DIFFERENCE in torque, the classic 16g "hit". But the other turbos are building and making practically the same torque at the same rpm, given the same setup.
