Garrett just sent a newsletter out about a new turbocharger speed sensor:
http://www.turbobygarrett.com/....html

From their website:
"Comparing boost levels and shaft speed on a compressor map, you can determine the ideal operating conditions to insure peak power over a wider operating range."

Can someone explain this a little bit more?
I understand once you know your wheel speed and boost pressure, you can calculate you air flow with the compressor map. But I also figured you could calculate your location on the map using hp figures too.

 

I noticed an ad in the latest turbo magazine about it. Think it might have been in a sema report.

 

you can control boost by shaft speed granted you have a capable EMS

 

it says it has a 0-5 volt output, is this correct?

 

Hi mrlegoman-
The new Garrett Speed Sensor readings provide you with a quicker means of plotting your operating conditions on the compressor map. Calculating air mass flow from assumptions for fuel rate and a/f ratio can also be validated by comparison with the turbo speed data plotted on the map.

And, NLR-
Yes, the Garrett Speed Sensor does put out a 0-5 volt output that you can datalog.

I hope this helps!

 

great. This means anyone using our ams-1000 can use that to feed our 0-5 volt input for boost based off of shaft speed or throw it into a ems to trigger an output to our decrease input to drop boost if shaft speed exceeds a set point!

Awesome....we were going to develop one but now I dont need to

 

thats awesome. sounds ideal for the rally guys. even cooler it works with the ams-1000!

 

i saw that at pri. very cool

Of course you have pictures of this product installed ?

How is it installed ?

 

Both inquiries will be answered on our website by tomorrow (installation instructions and installed photos).

 

What’s the accuracy difference between these easy to install sensors over the ones that read shaft speed? The ones that are installed in the bearing housing that require a groove to be cut into the shaft.
