    aftermarket (granatelli/other) Mass Air Sensors?

    Ok, so i noticed that alot of people with (somewhat) modded cadillacs seem to have a granatelli or other performance MAF on the car.

    there is no direct part for the northstar motor, however there has to be some part that works if other people have them...

    First, for those that have them, did you notice a gain?

    second, what part do you have?

    third, i've heard that we have the same maf as the LS1 corvettes and a number of other vehicles. if this is true, then any one of those maf's should work...theoretically...

    just looking for some input on this idea first...thanks guys!

    Yep you are right the LS1 mass air is a direct replacment for the 01 up Northstar. I am using a Granatelli on my car and it picked up my et at the track. I went from a 15.7 ( I was on my 20's at the time ) to a 15.3 in the 1/4. Same day same temp just 35 mins later. Hoping when our track opens next week to see if I can get into the 14's with the stock 17 inch rims.

    the 01+? what about the 97-99 cars or thereabouts? mine specifically is a 97 deville and im looking for a possible alternative

    EDIT:

    searching GM parts direct has me scratching my head...it shows the 97 deville to use a different sensor than the LS1 cars, but the same sensor as the 92-2002 eldorado...which has a second part number for the sensor that is on the LS1 cars...so it SHOULD work? i dunno...if the 97 deville and the 2002 eldorado use the same sensor and the eldorado can use the LS1 replacement sensor i should be able to too...i'd assume...

    Keep in mind that Andy Granatelli got socked with the biggest consumer fraud fine in history by the FTC.

    that i'm aware of too...thus why i wanted to test the waters here before jumping off to buy one. i've heard of mixed successes with MAF swaps...some getting nice gains while others losing power...it seems like most of the dynos i've seen of modified northstars have an aftermarket MAF on them and seem to do well...but as you and i know that doesnt always tell the whole story either...just looking for a few positive (or negative) ideas to see wether or not it would be worth it to try...

    01STS. . . Did you reuse the MAF screen? Or did you leave it out?

    Re: aftermarket (granatelli/other) Mass Air Sensors?

    Also, are you using the Granatelli part #350112? Was the plug an exact fit?

    i was wondedring the same things...his seems to be the only positive account so far and it seems to be a bit out of the norm...waiting for confirmation..

    EDIT: FWIW i was just doing a search over on corvette forum in the C5 section (the maf's swap) and they are dead set against it...it makes me wonder...if the MAFs are the same or are compatible...why such different results? could be quite a few things...

    And as a side note... I think we might have our Granatelli's confused here... I might be wrong, but do some research on it. Same name, different companies. No fraud from the one producing these MAF's.

    Re: aftermarket (granatelli/other) Mass Air Sensors?

    Use the same year Vette mass air for your year Northstar. If you have the early years with separate IAT and Mass air plugs use the early Vette style. 01 and up cars, GM put the IAT inside the Mass air with 1 simple 5 wire connection.

    DO NOT REMOVE THE STOCK MASS AIR SCREEN!!! If you think this is a cheap and easy way to give you horsepower is will cost you about 4 HP on the dyno. I have seen it may times and it always costs hp.

    Same name, same roots, different divisions of the same consortium.

    It is not a "screen". It is an air flow straightener.

    Re: aftermarket (granatelli/other) Mass Air Sensors?

    If you go with Granatelli the part number you want is 350119-C for the 01+ N*.

    Now lets take a look at some recent information we've leaned, again.

    What does the MAF control, or help control that you think it's going to make an improvement? If you're thinking AFR (Air Fuel Ratio) you're wrong. Air Flow, maybe? Wrong again. No one but no one has dyno proof that aftermarket MAF's do anything at all. That 4/10th of a second on the track can be anything. That could be the lost weight from the fuel you burned the previous run. Show me proof from a dyno and I'll listen.

    We do however have proof that adjusting the AFR from totally lean to totally rich with NO affect on the HP output at all. The computer is to smart to be fooled by that. Not to mention there are several sensors involved most of which will compensate for the changed MAF signals and bring the car back to where it wants it.

    Don't waste your money.

    Yeah I picked up that amount because I burn 400 lbs of fuel in one run................

    im not doubting your results, but they are so atypical of MAF swaps that it is hard to believe...you might have had a faulty MAF or an improperly calibrated one and the swap to a good one netted you those results...your story is one good one out of a mound of bad reviews we've all read...but if yours worked that well for you i am glad you got that kind of performance from it...i suppose if i got one used for a good deal it couldnt hurt but to try it for a couple passes...
