Not all true. It depends on which MAF you get. With some MAF's, your car won't run properly without a chip telling the computer you've added a larger MAF. You may even lose power if this is so. Some MAF's have already compensated for this by using a different size inlet tube so the right amount of air gets to the sensor. It all depends.Originally posted by D Man@Sep 4 2004, 09:38 PM
If you get a 80mm MAF you don't "need" to do or get anything to make up for the larger MAf.
Now the Yamaha is a different engine, but I'd guess the same concepts apply to both it and the Duratec. On SHOForum, most everyone (okay, not everyone, but most people with mods) have an upgraded MAF, yet not many have the 69mm TB. According to Yamaha V6, and I'm going to take his word on it, the throttle body upgrade is not worth the money, and it's only $119 in the first place. Cheap in the SHO mod world. Keep in mind that he has done just about every mod conceivable to his Super SHO, including FI. If he has an upgraded MAF, and not a bored TB, I think I'll stick with the MAF as being my choice of the two.Get a larger TB or something that'll help the flow better than a MAF in a N/A car
I thought i felt an increase in the the high end, but no #s to prove it. The inside is a lot less obstructed than the stock maf. The car WAS a 99 duratec with stock injectors (R.I.P.), i now have an 01 and it uses a 6 wire maf so i can't use it.Originally posted by sable97@Sep 5 2004, 01:30 AM
Dagamemnon, did you notice a difference with the 75mm MAF in your car? Which car do you have?
Not true. Some MAF's, as I already stated, come with a larger sampling tube making a chip unnecessary. But you are correct on the TB. Nothing is needed for a larger TB.Originally posted by Kermit@Sep 5 2004, 12:03 AM
A larger MAF REQURIES a chip or a new program. A larger TB does not necessarily make it necessary for a special program.
Correct.....not worth it.Originally posted by LoadedLX@Sep 5 2004, 07:22 AM
so the consensus is "don't waste the money"? i didn't wanna blow a lot of money on something i won't "feel".
Yes, the 75mm Pro Flow MAF is a very good bolt-on without messing with a chip.Originally posted by D Man@Sep 5 2004, 09:02 AM
It's hard to say if it's a "waste" of money but, their are better things you can buy that are better for the buck. The MAF is roughly $200 and it may get you 3-5 hp on the dyno. Not enoguh to feel on the "butt-dyno" but the numbers will be their. I got one of the Proflow 75mm "bullet" style ones. With the Proflow, their is no need to upgrade the ECU to compensate for the larger MAf. But I think ever other company that sell MAFs have to have the ECU upgraded.
Here is the chrome 75mm MAF I got for my Duratec and to me, it was worth the $$
