After market MAF sensors and gauges...

Been reading (there's a shock) about air flow, and boost pressure. I'm intrigued to know whether there are any aftermarket air flow sensors and gauges available (like I'd put in a gauge for oil pressure for example). Had a quick search on the interweb, but didn't find anything, other than replacement parts for cars which already have them. Anybody any ideas?

what are you hoping to learn from this my good man ?

Just interested (nosy) really - be nice to see if air flow changes due to any porting work or changing exhausts/manifolds etc.

It would be good to see the correlation to if any to map and air flow.
On a nice flowing system you'd thing that MAP would be indirectly proportional to air flow?!?!

Pretty much what I've been doing on my motor using the voltage reading of the standard MAF for datalogging. Hence my previous request on info regarding scaling the MAF.

If you want I can advice you which software program to download and send you some of the files I've logged on my Zeitronix ZT-2 unit. It will give you an indication of the correlation between RPM, Boost, AFR, EGT, Throttle Position and MAF.

Thanks JNL - that would be really interesting

send me a pm with your email adress and I'll forward you some info sometime tomorrow.

PM'd with the info mate
