OK, this is a rather popular upgrade to the supra's, they get an AFM off of the V8 lexus's. And the only difference from the turbo supra's AFM is that the lexus AFM flows 25% more air than the stock 7MGTE's AFM. And the stock supra turbo's AFM is a carbon vortex, so I believe this would only work on the S5's.





Anyways, does anyone know if this would work? I know the NA supra, and S4 NA AFM's are interchangable because I have swapped them out, and my car acctually ran better... So does anyone know if this has been done?







The reason I ask is because I have one, and I am looking to sell it because I am going to put a VPC onto my 7MGTE rather than a lex AFM, and larger injectors...



Ohhh, and also when you put on the lex AFM, you also upgrade to 25% bigger injectors to compansate for the extra air flow that the AFM alows, but I am wondering if they are compadable.





If anyone knows post it up!





And obviously the benifits would be a more free flowing intake system...

 

s5 is the sam as an s4 it just looks different.

 

Wait... Isn't the S4 a flapper door, and the S5 is a karmen vortex?





Those are nothing near the same.

 

no.... none of the rx7s used a karmen system.



the s5 uses a hotwire system i think.

 

can someone explain with the karmen system is?

 

the s5 uses a sliding cone, it works the same as the flapper it just looks a little different

 

The Karmen vortex is a air flow measurement principle used to measure large amounts of air. The Karmen vortex principle involves the use of a vortex generating rod to creat vortices within a measuring chamber. Positioned on either side of the measureing chamber is a transmitter and a reciever for passing either altra-sonic waves, or infra-red light. The Vortices will distort the sensing sources, and the rate of distortion will indicate the volume of air flow.





Simple huh?

 

How much for the N/A Supra AFM?

 

and if youve ever seen an s5 afm.... youd know that isnt what it is







its a flapper style .. just a diff design
