This has probably been posted somewhere before, maybe even one of the links on the sticky's.

Just in case though, it's pretty decent plotter, enter your specs then select any of the turbo's in the grey box to see your engine plotted on that snail's map.

Not to mention a library of damn near every brand/style turbo compressor map you could want.

 

that is pretty bad *** i like it

 

nice map looks good on my build for a gt30 but im goin sc6176

 

I remember this link before.

I only like the maps for all those turbos.

The calculator does not work with me.

 

Is it just me or does it always want you to run 16.3 psi? Is there somewhere that I can specify how much boost I wanna run?

 

i had to toy with it for a bit, i sort of had the same issue, then again I really think there is something I'm missing

 

The only things you really need to mess around with are your target power, engine size, AFR, BSFC, engine speeds, and intake temperatures. The approximate VEs at redline, peak power, max boost and min boost are good approximations, so you can leave them alone.

If in doubt, just play with your HP number and engine speeds (RPM) and use the following for:

AFR = 11.8
BSFC = 0.48
intake temperatures = 100 (for all of them)

And then just start looking at turbos. Easy peasy.

 

any chance of a sticky because im lazy and I'm constantly finding myself looking for it from somebody else s computer? (therefore not bookmarked)

 

.57 a/r t3/t04e it is, thanks for that link. Bought a new computer and couldnt find that ****** anywhere, although I think it was Shanes TurboCalc I was using before.
Nonetheless,

 

nice told me hx40 for my ls
