Depends on the size of the charge piping that they are housed in. The MAF sensors in 2.75" charge piping will do about 600whp (DJ). If you go with 3" charge piping that number will go up.

We didn't change the mafs until we went above 1000hp

Absolutely correct. One thing I'd like to add is that superchargers do eat up some of the power, so the apparent power threshold will be less. That's why we went to 3" charge piping on our Stage 2 Supercharger Kit.

Any progress on that stage 1.5 SC modification?

We're almost ready to do preliminary testing.

Need a car for some testing?

I don't understand how this is possible if the above is true? Did you use 4" charge piping?

Interesting..............

Pretty sure you guys used UPREV GT Maf's on your car. This is the link that Sam posted to the set up

Two main factors, Maf location and pipe diameter, With our blow through set up and our 3" piping you will be at 4.8 to 4.9 volts in the 600 WHP mark. this have been very consistent due to our Maf locations.

Now if you have the stillen draw through set up then your mafs will max out much sooner, I have seen them max out at low 400WHP .

No They are not the GT mafs's Calibration from UPREV, as i have said that before in that same thread. Our calibration has much bigger sealing.

Been on the dyno all today working on new set maps for the upgraded compressor housing on our GTM stage one. I'm still working on the 91 gas maps right now.

The results are very good as expected, let me just say we are making over 450WHP on the stage one with flat torque curve all the way to red line .

How does the area under the curve compare to the stage 2? I really only want 450 WHP, but the responsiveness and torque curve of the stage 1 SC is very attractive. That's the one I test-drove and really liked it.

And like I said, let me know if you need another test car :-)

I was more so saying that they are not stock.

So to be clear you have that company make you custom MAf's to your specs? They way you worded it before you were saying that they are the same sensors...
