Not Mine: 2 INDYCAR EFR6758 turbos $450 each
A friend posted this on the Indiana Miata Owners facebook group. That's all I know about those turbos.

Can you post up the text for those of us who don't use facebook?
Have a friend with a few indy motors and turbo manifolds but no turbos. He may be interested. |
The price is too good to be true? Caveat emptor?

Regular EFR 6758 has 7 compressor blades, the one in picture has 6.

Hmmm, full-race has pictures of both 6 and 7 bladed compressors. BorgWarner EFR 6758 Turbo - Full-Race.com The picture they show for the T4 .80 has 6 blades. Or maybe the INDYCAR ones are different. I don't know.
page 67 The speed sensor is powered by a +5V supply, and the return signal is a variable frequency square wave that has maximum amplitude of 5V and has a 50% duty cycle. The frequency of this signal depends on the speed of the wheel. Each passing blade creates a pulse, and all the EFR wheels have 14 blades except for the 67mm (which has 12 blades). The sensor embedded electronics divides the blade-pass frequency by 8, and then the resulting count forms the output waveform. Here is an example: https://www.miataturbo.net/attachmen...ine=1413343914 |
