So you want a super single say a Garret Gt4088R or 94R ???

 

Hohn, where do you find BB turbos for 400 less than s 300 based turbos?

 

LOL dang you spoiled it

 

all i want is a turbo that works. not one that s`posed to work. and i agree with hohn. where are the details. maybe it really is black magic and they are all brujos.

i would rather have the truth than get stuck with my next 2 paychecks going to somthing that might not work for what i need it to do!

 

It amazes me to this day how if someone mentions "injectors" you can end up with an argument double quick time.

For the rest of the comments, all I could say is that you "You can get close".

For example:

Good quality stereo system = $400
Top quality percieved stereo system = $2000

Good quality golf driver = $200
Top quality percieved golf driver = $500

No much real difference in the actual product for the consumer in either case.

The biggest dig in aftermarket Hp for me is not really the cost of production + cost of marketing + R&D + margin, it is the cost per Hp that irks me.

For example:

50 Hp injectors = $400
100 Hp injectors = $700

65 Hp tuning box = $325
120 Hp tuning box = $700

In the latter case there might be a few more parts included, but not the amount to dictate such a price difference. I can't believe that there is actually so much difference production costs. I believe that it is simply percieved values. Plus from a marketing stand point who would ever buy the 50 Hp gizmo if the 150 Hp gismo was almost the same in price.

Smoke and mirrors, it is the percieved value of the consumer in many cases that determines the price.

HTT! HTT sells that Garrett kits for <$1600.

Dynomite Diesel sells the Turbonetics kit for about the same price.

Comparing this to the $2K of a "silver" anything and such. Obviously, the cheaper B-W turbos aren't less expensive than the BB units.

Let's see A/R= Area/Radius. I don't see "turbine wheel grinding/clipping" anywhere in that equation


There are only TWO ways to increase A/R= I'll let everyone guess what they are. They can PM me if the suspense is killing them.

Clipping a wheel can make a given wheel flow more (at the cost of efficiency), but it does NOT change the A/R.

Why not go to a larger A/R housing which would increase flow AND increase efficiency?

I'm pretty sure most of us know that the "S300" is used as a generic reference for all the B-W dieselturboshop turbos. Some are S257s, some S362, S366, S368s, S370, S372, etc etc. It's just a big parts-bin smorgasbord.

Thanks for contributing to the thread you couldn't be bothered to read.

 

4088 doesn't help you over a 3788 (same compressor), and a 4094 has a crappy map at higher PRs.

4094 would make a killer top charger in twins, and MAYBE a sled pulling turbo where RPM is really high. But in a case where you need high PRs at lower RPM, it would suck.


In twins, you could gate it down and keep the PRs low where the map is fat.

*dieselfuelonly is learning.

 

Smokem1, I apologize if I'm reading you wrong. I think you're taking what Hohn has to say too seriously.

I would like to see some reasoning beyond "you have a lack of experience and knowledge". If you wouldn't mind, could you explain your counter argument with some technical detail keeping in mind that we are not all turbo experts and would like to learn.

thanks.

 

Dabblings is the correct word to use. I'm no expert. I'm trying to learn, and to share what I learn with others. In that learning process, I have arrived at questions that have been difficult to answer. Those who have the answers aren't sharing, and the "why" of it is baffling to my underworked mind.


Your personal attacks haven't advanced the learning in anyway, and rather than CORRECT bad or wrong information, you simply attack. As far as I'm concerned, if you don't explain WHERE and WHY I'm wrong, you haven't helped. Simply naysaying doesn't help anyone.

I think the 4094 would make a killer top charger, but it would have to be in very large twins in place of something where you'd typically use a 66-class turbo like a SPS66 or so. Yes it would be laggy as heck, but if you are building twins with a turbo like this (and the ginormous primary you'd put underneath it) then lag isn't a real consideration, because you're building a sledpuller or a dyno queen, either of which will have its operating RPM raised considerably.

If you are "much farther into this" than my dabblings, then you should be able to answer a lot of questions and provide useful info, which would be better than simply attacking someone personally. You should be able to answer why these factory "clipped" turbines are used and teach us. We've seen pictures that show clipping on only two blades-- why is this? How can we know that factory turbines are clipped for ONLY flow enhancement? Are we supposed to believe that a wheel wouldn't be clipped for any other reason, like balancing or flow trimming, or trying to match a less-than-optimal turbine to a different application?

Or you could explain why Garrett is wrong when they list this at their website:
It sounds like you have the knowledge to share, and your earlier post on the composition of a turbo was JUST the kind of knowledge others and myself are desperately seeking.

Any more that you can share would be of very high value to me and I'm sure to others as well.

 

I agree about some things being constant on internet forums!

Many of us desire to know exactly the misleading information and random BS from HOHN's underworked mind...

TIA

 

<-- never mentioned anyone being less knowledgeable than me. If I had all the answers, I wouldn't be asking so many questions!

 

Few things to ponder....
1) If I have say $3.00 in a widget and through good marketing I am able to sell it for $15.00, is there anything wrong with that if my widget performs as advertised?

2) If a person is happy with paying $15.00 for said widget that works well, are they silly for giving me the $$ when they may have been able to buy it cheaper had they done months if interweb research and spent countless hours of investigation?

Point is, if you are happy with your purchase, it really doesn't matter to me.

 

Howdy folks, JM2 c,
I’ve no real tech info for anyone (yet) and have not read many of Mr. HOHN’s
post’s, And I do see with confidences, HOHN can manage any typed assault.
I am personally impressed with his insights, and thankful that someone took his/her time to enlighten/ help, me /others
I value any person who takes the time to learn, and then turn around and give it away.
And to me, it’s any person’s prerogative to completely accept one product, yet question another.
I (like him, and many others) like to know any and all details that may or may not shed light on a challenging project, any reasonable person would.
