below is the compressor map of the 60-1 directly from turbonetic's site...

I did the calculations, and it turns out @ 12psi (1.92 pressure ratio), you need at least a displacement of 170 cubic in. (2.8 litre) to be in the sweet spot @ 8000rpm.

Coordinates:
pressure ratio: 1.92
air flow: 42

Recently, ive seen many peeps go with the 60-1 with 2 litre or less, and they make power? How can such a small displacement push such a big turbo? or this might be the wrong 60-1 that im looking at

are you incorporating the pressure ratio into the engines cfm/lb per minute?

 

whats the x-axis on the plot?

 

I wish I understood how to read those

 

I agree....

 

Ask and yee shall recieve https://honda-tech.com/zerothread?id=142398

 

holy **** that explained it very well....and it told me about compressor surge! i didnt know whta the noise was when i got up in the rpm's i would hera che-che-cge noise...... i thouht it was maybe an exhausee leak or something!!! wow my turbo is wayyyyyy to small!

very informative!

 

Alright, had to bring it back from the dead because Im confused
Looking at the compressor map..
I still dont see how Honda small displacement (without the use of NOS) can use a 60-1 when my calculations say a perfect match for a 60-1 is a 2.8 litre.

Also what the hell is 60-1 HiFi, and 60-1 innovative?

 

this is what im interested in knowing too....Some people have told me that the T04E Compressor housing is more efficent than a 60-1 compressor housing ?

 

a 60-1 hifi is a 60-1 compressor with a t3 exhaust side.

 

isnt hi fi turbonetics ball bearing system?? (single)
and innovative 60-1 is a turbo made by INNOVATIVE ...ITS!
