Turbo Calculator (Newly Released!)

[Frank]

In my opinion, this is the best turbo calculator that can be had on the internet, whether free or bought. I hope you enjoy and if you have any suggestions, please feel free to contact me. I hope to have the FAQ section on this page done soon.

http://www.squirrelpf.com/turbocalc/index.php

All configurations are savable and all images are hot linkable. There are around 86 compressor maps available with any configuration of engine parameters.

As a hotlinking example, I hope that my Daytona will produce the following results when I put that turbo on along with a PT1000 intercooler.

I think I broke it trying to figure it out :o

[Frank]

What did you do?

[mcsvt]

I was just trying to enter my own numbers and now when I open the window I automatically get a windows error and have to close the window.
Might just be a problem with my computer, to much work going on right now to restart though :)

[cordes]

Very nice Frank. That is quite impressive.

[mcsvt]

Hate to be a post whore, but it's working again.

Must be my crazy computer here at work.

[Frank]

Very nice Frank. That is quite impressive.

Thanks Brian! The hardest part was populating the database with all the pixel information on how to make php draw the information overtop of each individual graph.

It blows up my IE when I check it out... :(

[Frank]

Can you send a screenshot? IE & Firefox have both been working fine... well with the exception of the past 10minutes. I was messing with something. SHould be working ok now.

[altered7151]

:thumb: Excellent work Frank! Very nice GUI on that, I'm lovin the tranny/gear ratio feature. If I get my car out on the salt that should come in very handy!

[Super60R/T]

Awesome. Great work. Helps me see exactly where I want/need to shift aswell as a great graph of exactly where I am with the turbo I'm using.

[Millerman340]

So this looks good? How much farther can you push it? :)

[Frank]

Honestly, I really dont know! I know the garretts mainly because there is alot of data with similar size motors, dyno plots, etc.


Frank

[Whorse]

How can we figure out our VE based on a stock setup, and modifications to the IC, plumbing, intake, TB size, head, etc...?

[Frank]

You can't, but guessing is always better then assuming 90%. What you can do is always look at the pumping efficiency table in your calibration. OR just use what is already built into the calculator. THe biggest player is the BSFC number.


Frank

[GLHNSLHT2]

Ok frank here's one for ya since I'm not putting in something right.

16v Masi head, Ported, 1mm oversize vavles. Large plenum on the intake runners. Big Water/Air spearco, Ported exhaust manifold with T3 flange on it and external gate. See Alan's pics for the exhaust manny :)

JE pistons with either stock T2 rods and crank or some Hbeam rods on the same crank. I'd like to turn close to 8k rpms.

My preliminary thoughts is the GT35R with Precisions new ported housing and a .82 A/R for the exhaust. 4" exhaust for about 3-4ft as well and the wastegate will have it's own pipe. If you could plug in some #'s to your calculator and post them here or in a PM I'd appreciate it.

[Frank]

Here is the new TurboCalc I wrote.... you all should love it!!!

[minigts]

Man that's some fat coolness, but how do you determine some of that information to get calculations? Like volume efficiencies, the bsfc and max i/c loss.

[Frank]

Well VE can be directly grabbed from your calibration, whether stock or modified. This is located in your pumping efficiency table. It is rather handy. I can usually calculate a close VE, which is better then assuming 100%, by looking at HP, bore/stroke, and head flow curves. You don't have to be exact.

As for BSFC, there is a link which can help you determine your value. That 0.43 is a 420whp 2.5L at 30psi of boost... so ya... very efficient combustion. I do need to add more information to it, but you get the drift. I would consider a TI dodge to be around 0.55 and a TII dodge to be around a 0.52. Close is good. As for intercooler drop, well its not big, but between 1 and 3 depending on what you have.

[TurboBuggy]

best calculator ever! I love the new layout/features :thumb:

[Frank]

Thanks! Just wait till I get the prediction indicators down!

[puppet]

It's nice Frank ... very.

Now my dumb --- has to learn how to use it.

[Frank]

Added the Holset H1E and HX40!!!!

[Frank]

By popular demand, I have finally gotten the calc to allow the user to specify the number of turbos they would like to use on the car. It will update the numbers and graphs accordingly!

How come it only goes up to 4? Picking the turbos for "project Octurbo" will be a problem still. ;)

[Turbo3Iroc]

Can anyone give me some values for a T3 engine, specifically the BFSC and volumetric efficiency?

Thanks.

[Frank]

leave the VE, but pump the rpm up some. this will keep it very close. For BFSC, stock should be about 0.52.

[Turbo3Iroc]

Is the HP what you expect to make at the crank or at the wheels?

[gasketmaster]

Excellent job Frank!!!

Do you see adding the large frame turbos like Precision PT91 - PT106 in the future?

Maybe the maps aren't available?

[Frank]

That would be at the crank...

I have yet to find any compressor maps. If you have any inside voices, that would be awesome... I could easily add them.


Thanks!

[Ondonti]

I dont think those maps will ever be available. I dont understand why either :(
I really really really dont understand that policy.

[Turbo3Iroc]

Just some food for thought here because I assumed we were talking crank numbers here. I plugged in the numbers I dynoed from my stock turbo (2 different setups, I know its not exactly a 50 trim but thats the closest listed) and the GT35R I have on the car now and the boost pressure listed was within 2 psi of what it took to make that power. This is on a 250, 275, and 355 hp setups.

Assuming you are talking about crankhp...
Change the BSFC till the boost levels are the same (make sure the a/f and all the other stats somewhat represent whats going on first also).

[Frank]

Feel free to post links of your config so we can take a look at stuff.

[Turbo3Iroc]

Ok, more food for thought. I ran the numbers that I got with 355 hp and only changing the a/f as I went leaner the expected boost pressure went up. As I went richer it went lower. This wasn't a 1-2 psi swing. Going from 12 to 14 it went up 6 psi (24 to 30) and going to 10-1 it went down 6 to 18 psi.

[Speedeuphoria]

What about the newer Borg Warner turbos, s256/8, s366/s372??

This site has many of the maps

Not to burst your bubble, but I am going too. Those turbos are nothing more then options of the 200 series, 300 series, and 400 series turbos and are not much more then marketing ploys to buy bigger. The maps they use are the same ones that I have... I just call them by their series, not calling out each individual "model" when there isn't much of a change.

I think the issue with this is that your BSFC is set so when you add more fuel in the calc we pretend your BSFC stays the same so as you are burning more fuel you need less boost to make the same power. (pretend because its obviously not true)

Thats why it is important to have accurate a/f on there. Make everything as accurate as you can and leave guessing to a min.

[4bangermustang]

So what happened to it?

[Frank]

I had to take the site offline because it was hacked up pretty bad. I was thinking about starting a new site for it but have not had the time or resources.

[Ondonti]

Sad's :( I didn't mind the half broken site.

No consideration for a unlocked version of your excels if you are giving up?
I had worked on adding 3/S transmission gearing when I found the page 2 stuff near the bottom didn't work and had to be added to a higher cell number that was not broken (aka, replace transmissions I didnt' care about). My machine that has real MS Excel died recently though :(

Frank: The links to your webpage and to the turbo calc program are dead.
Are you going to set up a new web page?
Can I get a copy of the turbo match program? excel spreadsheet?

I'm pretty sure he's tackling this as soon as the photo problems on the site are dealt with.

I cant tell if that is supposed to be ironic or not.

does the pic not show up? on one of my computers the pic i posted up displays and on another it doesn't. i was attempting to show that mptune does have a turbo calculator in it if users want to use it.

let me try redoing the pic!

Now that's funny. :lol:

[Ondonti]

I liked it better before you clarified. I really miss both of Franks calculators but I liked his spreadsheets better. No need to backtrack to make changes since excel instant updates, no virus's. It was a valuable tool worth money.

[Vigo]

I still don't see it..

[firehawk618]

Link goes to ARJ Landscape now. I think it's safe to say it's dead.

hmm, thought you could add maps! you do have the ability to use mptune to do the same thing, i.e. compressor maps, gearing, etc.

None of the documents are locked. But I am using Open Office as opposed to Microshaft Office. Maybe the protection doesn't translate?
