+10 I'm here to end the thread on a bad note. j/k ![hiha](https://rennlist.com/forums/graemlins/roflmao.gif)
As far as performance difference, technically there probably isn't much difference between the 2 different maf placement styles. The one obvious benefit about a blow through setup is you could run a BOV without suffering any negative side effects, plus if you get a boost leak you can just drive around n/a.

I like the idea of the boost leak friendly aspect but if you are going to have to overcome allsorts of other problems to get it to work, and even then with no performance advantage, then I fail to see the attraction of the blow-through setup.
Thanks. Scott

Why would they need to tell me where the MAF is installed?

John I may have to try moving the MAF since I bought a tial bov. I was planning on contacting you to see if this was a viable option, and recommended placement?

In a quick summary of why i thought...
Because the VE of each turbo and set up is different, which is why you have to know each indidviduals set-up to calculate VE of each different turbo, intake system and pipes. But. if in a blow through layout. The VE is determined by the actual mass of the air flowing past it because that is then the EXACT amount of air getting into the engine. No guesswork in this set-up. (Assuming base VE of block and head are equal)
Am I wrong?

Our software was written to support true Air Mass.
This thread is for SFR MAF. I do not want to take any more space here.

Dont worry about it John.We designed our piping to be used with the kits out there so they can keep their software and all the good stuff that they like but still have the ability to move the sensor to a more ideal location(ofcourse this is just my opinion).

Thank you Tim. Based on my experience, the type of sensor in use for blow-through and the position of the sensor play a huge role in the behavior of the system. Talk to your vendor before modifying the MAF system you now have!
Just a quick note, so no one misunderstands this. The MAF we (Vitesse) supply, must be used as is! Do not try to remove the sensor out of the tube (well unless you want to purchase another sensor).

Hey guys, since this thread is getting some more mileage I want to thank both Tim and John for contributing their knowledge to us, as well as everyone else for being reasonable and not flaming away.
