:evil We need a good tread on the cfm flow rate comparison on the different current available turbos out there on the market....:dead-horse-fast2: .

This could be an aid/asset to the folks who are planning a turbo upgrade from stock, :evil or those that are just looking for more air than they currently have....


So lets post up some flow rates.


:woohoo: :bigsmile:



:thankyou2:
 
Here is something I picked up somewhere along the way, but I can't verify how accurate it is.

Turbo / CFM
HX35 / 600
HX40 / 800
T66 / 800
B1 / 900
H2E / 1000
HX50 / 1000
HX55 / 1050
HT3B / 1100
T76 / 1350
HT60 / 1400
B2 / 1500
HX60 / 1550
T88 / 1450-1750
HT4B / 1800
Big Brother / 1900
T91 / 2000
HC5A/HX82 / 2450
T100 / 2600
T105 / 2900
 
:ylsuper: :bow: Good info Ted, now we can use some from the newest huffers out there like the Silver Bullet, The SPS series, Phat Shaft's,S-300's, S-400's ATS's Aurora series ..... ect:bigsmile:
 
I had no clue there were that many Turbo's out there. These are all for the dodges right? How many of them actualy use the factory down pipe flange?
 
CFM means nothing without air temp, MSL and a compressor map. If you really want a good comparison, you'd need to overlay the compressor maps of each.

Aurora 2000 - S300G
Aurora 5000 - K31
Phat Shaft - S300 based 64mm pinwheel
Silver Bullet - S300 based 71mm pinwheel
HTB2 - S300 based 64mm pinwheel
Pro Street 66 - S300 based 71mm pinwheel
BD Super B - S300G
BD Super B Special - S300 based 64mm pinwheel

The older S300 turbos utilized a 64mm 11 blade pinwheel which often causes surging issues when coupled with a 64 or 66mm compressor wheel. The only way to previously eliviate this was to clip the pinwheel, but this process lowers the efficiency of the turbo. The newer versions of the S300 turbos offer a 71mm 10 blade pinwheel which offers much greater efficiency when coupled with larger compressor wheels. The new pinwheel also greatly reduces the turbos tendancy to surge under load, so future buyers of the S300 line of turbochargers, make an informed decision.

:bow: Another Killer Post :thankyou2: I didn't know that about the ATS Turbos....Smokem any cfm #'s for those listed??
:thankyou2:

Are these numbers the turbine side?? Some of these are conflicting with other posts on the same subject if they are compressor dimensions!!

the problem is that i have 3 different ht3b's, all three have different size inducers. when i look for turbos, with my junkyard skillz, i look at the size of the inducer, the exhaust housing size or ar#. the chart is for a general guide line at best. just don't consider it the end all of a guide.
 
I've got an excel spreadsheet but it's not an allowed attachment type :bang
 
As a general guide so far this gives a rough idea though...which can give folks an idea on selection choices....

Anyone have pics of the T-88's? T-91's? T-100's and the T-105? Is that the same family as the GT series turbos???:ugh:
 
heres some T-88 pics compared to a H2E ... if want some in the 100s ask chris watts

the GT series are garret style most popular GT-42 for big single pullers

and then there are poeple like me who have no idea whats going on with turbos. what can you expect from like a htb2 64/14. they call it hte killer b2. i am look at turbos for say up to the 400 hp range that tow good.
 
the HTb2 can support 500hp , iv seen 468 out of one with mild mods on a 12v
there good turbos

i like my steroid its decent too with mild sticks u can tow with it depends on how much hehe

Cool...Thanks!

The S400's I've been around have either a 70mm, or 75mm compressor. I've even seen one at 64. Usually, the 70mm ones have a much smaller exhaust side, too!

BTW, those turbos you just posted weren't the ones I was talking about. I was thinking the Silver Bullet was 68mm, but I wasn't sure. I also thought the Pro Street 66 was 66mm. There again, this is all what I was told, never ran anything bigger than a B1 (as a single:D)

Now this thread has some killer info!! Thanks guys keep it coming in!:rules: :ylsuper: :ylsuper: :ylsuper:
:evil :thankyou2:
 
FWIW, I'm beginning to really like the GT42's...VERY simialr to the S400's, but seems to be a lot more housing options available! That and compressor maps are readily available!

So far I've seen/had...GT42's
70mm/1.01 W/G Housing <----- On Joefarmer's rig.
70mm/1.15 W/G Housing <----- $50 Core that needs rebuilt...Top charger in towing twins!

And my GT45R
70mm/1.01 Non-W/G housing Ball bearing! Gonna be made into a 75, or 80mm charger...not sure yet:D:D

Also, the S400's can have either an 85mm turbine side, or a 95mm like a B2...IIRC!! At least these are the two I've seen...I'm sure ther are more options!
