List of turbos by size/flow

How hard would it be to create a list of available/popular turbos by their size and flow with another column for required mounting hardware, another for the amount of fuel they will be able to use, another with the potential HP of said turbo, then ideal applications, then random notes, and then "price"? Or really any combination of information that would be helpful to anyone searching for a turbo for their application.

Turbo | Size | Flow | Fuel | Mount | MAX HP | Applications | Notes | Price
------------------------------------------------------------------------
Stock | Small? | xxxCFM | Too small for stock | Stock | 350 | Stock | Worst option, works for some | Stock
Stock w/WW | Small | xxxCFM | Great for stock | Stock | 375 | Better Towing | Cheap upgrade, bargain results | $200
D66 | Slightly Larger than Stock | xxxCFM | Great for stock | Stock E99 | 375 | All Around Performance increase | Only bolt-in option for early 99s | $XXX
GTP38R | Good beginner turbo | xxxCFM | Stock up to 238/80s | Stock | 450-500 | Great for Street/Strip, Improved Towing | Bang for buck, best/only option for stock pedistal | $1200
Stock H2E | xxmm/xxmm | xxxCFM | Stock up to 250/80s | H2E Mounting Kit | 550 | Great for Street/Strip, Improved Towing | Upgradeable, you need to buy and expensive kit to run a $500 turbo | $500 turbo, $1200 mounting kit
Modified H2E | ...
S300 |
S400 |
S460 |
Sledgehammer |
QSSB |
GQSSB |
GT4202 |
etc...


There are probably a dozen or so very popular and highly recommended turbos so this list wouldn't get too out of control. Each thread ends up the same way...

What are your HP expectations?
What do you do with the truck?
Do you have other upgrades in your future?
How much are you looking to spend?
How much weight do you pull?
Run it w/o a wastegate... put a gate on it, put this wheel on this turbo... etc...

I only mention it because I was about to make another "What turbo would work best for me?" thread, and I was looking for similar threads with people who have similar modifications as me. If I had a single reference point, it would be easier to make assumptions based on the generic information available in a thread like this. I'd even volunteer to maintain such a list.

I'd go so far as to add links to vendors who offer those turbos, and any and all available information for those specific turbos, MAPs and wheel and housing options as well. People could post what they know in the thread and I could just add it to the original post... or modify a spreadsheet or something. I know information like this can all be scrutinized and everyone has their opinions but I'm not looking to make a "turbo bible", just a cheat sheet for noobs or a quick place for experienced enthusiasts to point other noobs too.

If this type of thing is already available for mass consumption, can someone point me in the right direction?

Thanks,
Jack - Turbo Newb

If I was able to link vendors you'd know!

Even if it just helps me, I'd be happy

Re: List of turbos by size/flow

It's more complicated than simply using compressor flow.... what happens if you have one turbo making 35psi on on your truck with 35psi of backpressure and another making 35psi with 50-60psi of backpressure.

Airflow needs to be addressed by overall flow but I can't think of an easy to do it. It's all a compromise between efficient boost and spoolup characteristics......

Re: List of turbos by size/flow

You need to add air density as in lbs per minute, that is more important than CFM, 1200 CFM of hot air is just that.

Re: List of turbos by size/flow

This is the input I'm looking for. If that variable wouldn't play a role in this chart due to the other variables associated with it, it doesn't belong in this chart. I didn't see this as being the source for deep discussions about lbs/min or cfm or anything, just a simple reference guide of valuable information. I don't want anything on here that would be so misleading or vague it was dangerous.

Matt, as far as the direction you're taking this, if back pressure or drive pressures were constants on a given turbo, lets post them up as well. If we know the drive pressure on a H2E was 1:1 and that on stock it was slightly more (fill in value here), then we could document that. If a turbo's drive pressure isn't constant, and varies by application, maybe just some generic baseline figures to get people into the ballpark.

The scenarios you guys are addressing could be brought up in a more specific area, not necessarily a reference chart. Your input is appreciated though, if you wanted to start this off right.
If I could get all of the images for the maps too, I could host them and link them to the doc.

If I already had all of the answers, I wouldn't be looking for a reference guide like this.

I was being sarcastic/uneducated about the $1200 for the 38R btw, unless vendor wanted to step up and take advantage of the attention that price has been getting

Re: List of turbos by size/flow

With all the turbo questions lately this would be a good sticky chart.

I also want to know where your getting a 38r for $1200.

It can even be variable with nozzle size and pulsewidth.....

If I could edit my posts I would change it to something more realistic. My example is a poor example of what the chart would actually be, and the data within it is all random.

I DON'T KNOW OF A 38R FOR SALE FOR $1200

BTW - The numbers I gave you could have been skewed by the fact that the injector was flopping about in the head and spit the copper washer through the injector cup. When I get her back together, I'll re-scan and get you some numbers.





In the meantime, can some of you, more knowledgeable members, please supply me with some data to get this chart moving please?
