Whats up all. Recently I have been dialing in my fueling on my vitara build @ 21.6 psi. So I decided, What the hell, I need to look at the flow charts, because most say I will be blowing hot air at that psi on that small turbo. However the flow charts say that I can achieve my desired psi AND still maintain 70% efficiency, HOWEVER, Im unsure how to tell what part of the 21.6 psi line im hitting. ie, am I WAY out like I think or not?.... anyways here it is. I kinda think a larger turbo might help.
Red line is peak boost = 21.6 Psi @ 2.45 PR
Light blue is spool time
Green line is surge limit
Dark red line is what my math says should be my MAX capable CFM, and where they cross is off the compessor map
Green X is where ID like to be at @ 21.6
I have all my math written down on scratch paper if anyone needs to see it. I think that covers my question. Thanks in advance
my kinda thread! I've been looking into the same kind of things for my 15G.
how did you come up with your surge limit line? that's usually denoted on the compressor map itself, the far left lines... the light green looks more like a spoolup line to me.
anyway, what I've learned:
you can't just slap a 19T wheel and cover on. they won't fit in the housing, even if you rebuild to a "superback" style bearing. it won't clear properly.
solution: ARD 19T conversion wheel with a smaller exducer diameter Billet Aluminum Compressor Wheel, TD04HL, 19T Conversion
problem:
even if your compressor can flow 360+hp worth of air, the TD04H turbine can't shit that much out, so you're effectively limited to ~330hp.
this opens up the hotside enough to flow 400hp, or at least max out the 19T compressor wheel.
I'm seriously thinking the ultimate d-series street turbo would be a 19T compressor/ARD TD04H exhaust setup. that's more than enough to get you 350whp in a TD04H/Greddy footprint, so you get fast spool and compact packaging
I think the solution is waiting for a 19t to pop up for sale somewhere and get it rebuilt if needed. Otherwise you're going to need to run the 21.6psi and just deal with it because I think that's practically maxed out for you.
Or you could run any turbo of your liking that fits your manifold and DP

Ya. I really like the spool time of the 15g, and I have looked at the 19T as an option as well. I was more in favor of a GT2860rs. Just doing the same math on that flow chart, it seems more CFM for less psi.
The light green may be the spool up line. Again first time reading and doing the math on a flow chart. I didnt not realize it took so much to retrofit a 19T into the 15G housing. Good info. However I am definitely more enticed by the fast spool time. Makes a DD a lot more fun. Reviewing my datalogs, I hit 22.3psi..... It was cool out. When last time it was warm out.
Oh ya, can anybody tell me how to figure out where my rpm range would fit over/on this flow chart?

right, that was my plan too before I found that ARD wheel, I think the TE04H wheel has a different profile than a TD series and would require a lot of work to be done on the greddy housing to get it to fit
No, it does not work like that with an 19T.
The HL is for the compressor housing, to be able to nest the big comp wheel.
It uses an TD04 core and TD04 exhaust housing and a TD04L turbine wheel.
The small exhaust side on this turbo is holding it back a lot. I have used it before. Great turbo for smaller engines to make power.
No. I think the reason is because I can run a lot of timing with the E85. I have seen some write ups about DYI elbow porting but Im unconvinced it will help as I hit 20+ with no modification. Sorry when I say housing I was referring to that shit elbow. But I have heard the cast mani is not the greatest either.
Really starting to like the 19T idea more and more however.
Holy crap, from ARD, 19T compressor wheel $215.00, and the 19T housing is $195.00, a local speed shop has my GT2860rs for 350...... Damn it. I hate when this happens. But the GT2860rs will need a new mani and dp/elbow to work... so what to do.....
@ SOHCitTOem No build thread but I think this will cover it... may be missing some stuff. cant remember everything.

Anybody got a photo of the JRSC Y8 (3 RIB) Crank pulley or a photo of it next to a stocker?
Was there ever a 4 rib crank pulley produced by Jackson Racing?
Hey guys!
Im going to turbocharge my d16y7 soon and I was wondering about engine management, If i say id buy an P28 socketed and chipped ecu from H-tune. co . uk, Can i plug that ecu to my computer and connect it with Crome or whichever tuning software we use?
Thanks!:online2long:
Hey guys i just bought a civic with a built d16 turbo engine with the common vitara setup, its been running fine but the manifold was cracked badly and blowed like hell also looked like a 10year old welded the manifold so the quality is s*it. im not a bad welder and considering making a new...
Hi guys!!!
Some of you probably seen my car before!!!
So now its time to post my full built thread!!!
After a long time,lots of money,stress and working ours i made the faster and most powerfull D16 for greek standards!!!LoL
Down here they never tried to turbo a d16,so since i came back from...
Been working on a turbo setup for my crx for a few years, just put motor in, finally ready for the turbo.
I was wondering on the effects of altitude on a turbo setup.
I spend 1/2 my time in Denver, about 5000', and the other 1/2 up in Frisco, my driveway is at 9200'. Some of the mountain...
