The air coming out of the crank vent enters after the maf sensor and isn't measured by the maf sensor, so I don't understand why you would say that an maf setup would be required to run back to the inlet. If you could please explain your reasoning on this, I would really appreciate it.
I ran VTA on maf setup for a LONG time on my personal vehicle, and had no issues whatsoever. I also know of quite a few shops that run VTA with maf setups without issue as well.

So we are going to Speed Density. Does anyone have a suggestion or were to install the IAT sensor? Does it have to be on a straight section? |

If actually planning to move the sensor, you are going to want it as close to the cylinder as possible because the IAT sensor's whole purpose in speed density is to estimate cylinder charge temps. So, the closer you get it to the actual entry of the cylinder, the more accurate these estimates will be.

Place the IAT sensor right in front of the throttle body, use a chunk of stainless steel tubing as its less prone to heat soak than aluminum 321 is better than 304.

It has to be on that intercooler pipe that connects to the throttle body. I think the Perrin piping is STN STL but I am not sure. The location of the pipe sucks, it goes over the turbo and then besides the coolant filler tank . |

Also, SS may be less prone to heatsoak, but it is also much harder to cool down once it does. My IC piping is SS instead of aluminum, and it takes much longer to cool it down than similar setups running aluminum piping...it also takes much longer to heat up vs aluminum piping too though. It is a tradeoff... |

Turbo blanket the turbo and relocated the coolant tank = happier temps.

Regardless get the IAT as close to the TB as possible without picking up heat from the surrounding components. |

OK, now I see why you were concerned about the galvanic reaction/ corrosion. I would never weld the two!

Juan, Here's one way to do it, but it involves taking off the IM.

I am on SD .
The car is super smooth and really quiet during cruising vs maf. Ron has done an amazing job with the tune. It seems that I lost about 200rpm of spool but the whp/wtq gains have been significant. I probably will be swapping the 1200cc injectors for the 2200cc injectors very soon. Last edited by juanmedina; 02-17-2013 at 08:06 PM. |

didnt see anything in his mod list that said fpr, that be a good amount of money to swap his lines/fittings and buy a regulator, if he doesnt have any rails or lines now, even more, could easily spend 350-500 on all of it, sure having the fpr makes adj nice, but im sure he'd rather get new injectors instead
