I need some advice.I am going with a blow through MAF system. However I had not planned on running an intercooler since I would be running a water/meth system. I went with a blow through because I had been told and read that are more accurate and better tune ability. Now I am hearing that I will not have enough piping to use the blow through without going with an intercooler. Is this true? Here is the information on my MAF. I read it and sounded exactly like what Ineeded. Did I make the wrong decision?
VMP Blow-through 75MM MAF housing and SCT BA5000 MAF sensor
Part Number: BA75MM is a package which includes VMP housing and the new SCT BA5000 Slot Style Sensor, good for 250-700RWHP, use larger tube more range. See option details below.
For installing on pre-05 vehicles
Add 05+ 6 wire MAF pigtail, requires soldering
Add VMP 05 MAF plug and play harness for 94-98 V8 or 94-04 V6 (uses 05 MAF's built-in IAT)
The ultimate MAF for blow-through applications! Great for Procharger, Vortech, Powerdyne, and custom Turbo Kits. Works great on any year MAF based vehicle from Fox bodies to 2008s. This sensor in a 75MM housing gives enough range for most applications making 650RWHP or less.
The 05+ slot-style MAF sensor has been found to work great when used in blow-through (MAF after the compressor). It provides a clean and stable signal, resulting in better driveability, better fuel economy and consisent WOT air to fuel ratios. The 05+ slot style sensor can be used on Fox bodies with an EEC-4 and 96-04 vehicles with an EEC-5. Blow-through is the best way to go for forced induction applications (excluding roots blower designs). The vehicle will be more responsive and easier to tune when the MAF sensor is close to the engine, many suck-through supercharger kits place the MAF 3-9 feet away, which results in many driveability problems. With a blow-through MAF the BOV/BPV may be vented to atomsphere to reduce heat soak on non-intercooled applications.
We designed this MAF housing specifically for blow-through applications. It is 8" long to straighten the air as it passes by the sensor. Both ends are designed to accept a ~3" silicone coupler, grooves are machined into the tube to prevent hoses from blowing off. It is annodized silver. The VMP housing is a true 3"/75MM ID for maximum range, other products on the market use a 2.8" ID tube, the smaller ID can cost you nearly 50RWHP worth of MAF sensor range.
Bigger is not always better!, the 05+ MAF sensor works best in a 3" housing, going to a 3.5" tube severely reduces signal quality, a 4" tube makes the signal quality unbearable. Most intercooler pipes are only 3" anyways, having a huge MAF housing will not improve flow through a system if all the other parts are smaller.
Recomended power range: 250 RWHP - 800 RWHP
