Turbo List
I've been thinking for a while about making a list of common turbo's, that lists them in order (probably by size) and lists some basics about them for people looking to upgrade.
For each turbo it could list a few important specs on the turbo, and then some useful bullet points like it's strengths/weaknesses, recommended injector size and fuel consumption using a set duty cycle and other set variables like boost pressure and setup. And maybe any common knowledge on said turbo. Then at the top of this list we could have some basic principals about turbo's, how they are named by size, supporting mods, spool time. I think a solid list like this would be really useful to de-myth and educate on some basic turbo principals. first and foremost just a basic list of common upgrades for our cars, then any following useful information we can produce with accuracy. I'd be happy to write it up if people would be willing to help with info, and suggestions on the layout{thumbup} |

I think this is a really good idea. I spent a long time trying to figure out what red green and black turbos all do. And there hp limits. Would be cool all in one spot
|
Do it! It would be great and informative
|
Great idea, all that info in one place would be choice.

Absolutely {thumbup}

Great list! they have something similar at Nasioc for all Subaru turbos, it would be great to add some further details such as RPM range to achieve full boost.
Make it a sticky & keep updating it with newer models |
The list of volume rating is the best way to go about ths, there are wayyyyy to many variables that affect power

There you go again, wanting to help, educate, and demystify about turbos. LOL:)

yup, volume rating basically shows the potential power output of the turbo. bhp = lb/min * 10 assumes that you're running an engine with a reasonable VE, the turbo is running a boost pressure that keeps it within the sweet spot of the compressor efficiency map, sufficient octane, appropriate ignition timing, intercooling and exhaust gas backpressure. There is more but that covers the basics
But what about developing a set of standard parameters so that we can provide general reference points for people looking to mod, like injector size, maybe fuel pump baseline, and maybe we can break them down into size by category - not to give a precise power rating, but at least provide a decent idea of potential. ------------------------ Constants needed for turbo data (feel free to supply data or suggestions) Intake (boost) pressure AFR Atmosphere temp and altitude Engine Temp Fuel type and grade Fuel pressure ( constant right? - effects afr) Engine volume (2L) engine stock standards like cams, crank, valves. ----------------------- things id like to provide about each turbo (please add to) lb/min injector size fuel pump (a nominal suggestion that will encompass turbo's performance) spool speed (vs. say stock IX, not a precise rating, just general based on turbo's specs) notes (stuff like, this turbo's great for.. or many people have x problem...) ---------------------- Then at the top of the list I'd like to put basic principals of turbocharger systems, like pressure change with temp things effecting spool speed and general notes turbo names & numbers - what they mean (really want this to be in there) advantages to basic specs like ball bearing and twin scroll also make a note on performance - talking about why just a bigger turbo doesn't mean go faster. I think I remember Turbonetics having some decent articles on some of this, so I'm gonna start hunting some of this information down. edit - It would also be neato to add an addendum(?) for other popular setups like 2.4L and E85. I think that would be simple compared to the rest of the list. |

As someone already pointed out the rule of thumb is for every lb of air your motor can ingest it creates 10BHP not WHP. That bolded part is important because the turbo just produces air it's up to your motor to use it. Boost is a function of your motor pushing back against the incoming air and is not a true measure of how hard the turbo is having to work. That's why asking "what's the max boost this turbo is rated at" is an impossible question to answer. It varies wildly from car to car and mod to mod. While you can speak in generals like "keep it under 40psi" but that's not accurate because at 30LB it may be working it's ass off especially if you have a 54LB a minute turbo and you're making 550WHP. The only way to know truly how hard a turbo is working is to have a shaft speed sensor installed or be able to accurately measure the air flow output of the turbocharger. So if I were you I would stick to flow ratings and wheel specs that should tell anyone anything they want to know. Because if you try and attach a boost rating or spool to it you're bound to be very wrong and ball parking it within 10lbs or 1500RPM isn't really helping anyone. -Michael |
Saving that data dump on my "useful **** to have lying around" car document.
Making a modification sheet for every turbo to adequately feed it is a bit... well... not useful. Do we really need to dumb this down that much? What assumptions should we be making about fuel used, fuel pressure, VE, etc to put together a list? You may be spending a lot of time putting together information that fits only certain situations and is more burdensome to navigate than actually knowing what to do for a setup. ie: if want to run turbo x then use option 32 modifications unless you are using E85 then use option 92 modifications unless you are running higher fuel pressure then you can use items 6 and 7 from option 32 in place of items 6 and 7 of option 92. |

Precisely flow rating should tell you everything you need to know on whether the turbo is right for your project. If you want to make 500WHP you're not going to buy a 47LB a minute turbo charger. If you want a quick spooling turbo and want to make 400WHP you're not going to by a 90LB a minute turbo.
