"Red- 10psi@1500RPM (For an example of a super-hard spool, generally we wont ever see our engines spool this hard)"

that's not even close from what im seeing.
i don't (didn't i should say,pre - intercooler install) see 9.5 - 10 psi peaks until upwards of 2500-3000 rpm someplace (depending on load) with the banks sidewinder.

 

your turbo is not super hard spooling

 

right.no ones is lol.
the red lines shown in the graphs for factory boost levels (around 10 psi) do not represent how a typical turbo kit uses it's efficiency range if your marking them out for 10 psi @ 1500rpm.
at 1500 rpm,im dubbing along boosting 0 in OD around 50ish mph.
upon takoff under heavy load,im sure we hit a couple lbs of boost maybe,but not our peak 10 psi that we see up around 3000 rpms.
he didn't do anything wrong.by saying this: "generally we wont ever see our engines spool this hard" he's just telling you he's not going to show you (with the red line) what a turbo kit boosting it's typical 10psi actually looks like in the efficiency map.

 

The reasoning of the RED line wasnt to show a 10psi setup, it was just to show a super hard spool in sort of a "worst (or best ) case scenario" on how that particular turbo would fair... I know I can see 10psi (albiet smokey and hot) at 1500 with my setup if I lay into it hard... Thats the difference fuel makes in a setup.

I plan on running several different boost levels through these maps to see how different setups would fair, you just gotta give me a bit of slack, I have orders to fill and a shop I am working on at the same time, so it cuts back on the free time a bit...

 

In your defense, you stated from the get go it was in reference of a 90cc setup, not a stock setup.

 

Could you explain in detail how to read and interpret a compressor map? You know, for the ones who don't know what this all means...

 

these will get ya started;
Compressor map reading for dummies. - Engine Tuning, Upgrades and Swaps - HondaForums.com

^
in the online calc there,use
6.9 or 7.3l
85ve
9.5 or 10 psi (whatever your boosting.that's for a typical stock idi turbo kit) or whatever for custom turbo.
3600 rpm
500 rpm step
then check out the results in the chart.see the top is in cfm and the bottom is in lb per min! perfect time saver.
if you cant use your minds eye after studying how to read the map to place a line through it,then figure out a way to make the dots on the steps from the chart to the map and then connect them using a photo editing software.then you'll see it.

Turbocharger Compressor Calculations

 

OK I see now you are calculating at 85% VE . Now you have me re-thinking my turbo upgrade.....Good thing I havent bought it yet...

 

Thanks for the air flow calculator link, Its great....I played with the numbers some and I still think a HX35 is going to run hot for me at full power up hills on my Motorhome. Most of the 35's run a 12cm2 or 14cm2 housing I think it will run EGT's up for me. I was thinking HX40W 16cm2 housing. It still fits the map it will just be a bit slow to spool and should get me 15psi by 2200 rpm and 20psi by2800 My shift point is 3200 on the Allison AT545. I know its to big for a truck application but should work for me.....I Hope.... Plus it has a 4" outlet to fit my existing exhaust system....Im running a J2 cam and 90cc of fuel..I should hit my goal of 300 crank HP based on other guy's builds. I will be putting up pics and my own thread when I get bit closer to starting the engine. That way I can update in real time as I do the engine swap in the MH.

 

Mitsubishi TE06H-22C 49185-02020
i can't find the map anywhere,and after searching for a few hours now,it's clear im not alone,but i would never guess that one would be close.though that is one long sweet spot right up the middle.impressive turbo.hopefully the teo6h looks the same but down lower.
that can't be what the sidewider is because look at the heart of the efficiency zone.it doesn't even start until around 1.44 - 1.47 / 6.5 -7 lbs of boost.
would banks use such a mismatched turbo? one has to doubt it,cus this thing is snappy right off the line.not high boost,but spool up and whistle is right there without lag.also the other issue with the map is the air flow is incorrect for the efficiency zone.

it's like you have to bring that thing way,way,way down and slant it way right too to make it feel like what we experience.quick,snappy,hard seats of the pants grunt right off the line........and then (not me,i never tried) falls off hard to nothing past 12 psi.
in order to make that one look correct,you have to simulate that your diesel is much smaller in size so that requires less cfm so it follows up the sweet spot and could boost up to 19 psi perfectly.
it can't possibly have a map that looks so high up in the boost range,and not slanting up to the right in the map for higher cfm.....or im not reading it correctly.doesn't feel like it's a closely related map.i dunno.

 

Educated guess here... the TD whatever is probably a size smaller than the TE. For instance, like an hx30 and hx35.

The thing about the big long sweet spot is it isnt very sweet, its only 77% efficiency.

 

From what I can tell, the TD is just a shade smaller than the TE, but share the same basic Mitsubishi platform. Both use the same rebuild kit, and parts such as CHRA and housings are listed as fitting both chargers. Below are the specs for a TD vs. a TE, but configured for use on Subaru engines. Still, I think the map for the Gen II Sidewinder would be "similar". Odd that such a common turbo would be so hard to find information on!

77% efficiency isnt bad actually, even the BW turbos are in the 79-80% range...

As far as the big long sweet spot goes though, Its not all that impressive... Even an ancient wheel like the T61 in my upgrades has a larger peak efficiency band, thats assuming that the TE06H-22 is even anywhere close to the TD06H map... Take into account the "upgradability" of the Mits turbo, and your stuck... Best thing you can do to a Sidewinder is find a good turbo that bolts into place of the Mitsu...

 

^if your looking to remove your engine from the truck,swap a cam in perhaps,install a hot ip and put in head studs so you can boost over 10-12 psi that is.you know just a week of down time or so and a couple grand.

otherwise the sidewinder is the perfect turbo of choice already and the best thing to do, would be to keep boost at recommended levels for the turbo and drive the speed limit.

 

Honestly, the whole point of this thread is more than "stock" power, IE Custom turbos and kits. The very first post makes it clear this is not based around a stock vehicle. Starting to wonder if your trolling... Fwiw, that is what I at least am looking for, and what i plan to do and then some, along with i think everyone that has posted in these kinds of threads with the exclusion of yourself. Which is of course, why im posting in this thread.
I hate to be rude, but its the same thing over and over and over.. I just dont think we need a mpg>hp poster boy in the performance threads.

Racin- I was thinking the BW chargers were in the 80+ efficiency range? Something i find interesting, according to what Ford F834 said, the gen II banks is pretty much identical to the hx35 ironically. 56mm comp, 12cm housing etc. hell even the AR is almost right on, my hx is 82 and the banks is 89
