88mm pro m MAF on 2000 gt?

ledee416 · 09-24-2009, 11:06 AM

hey guys,

I recently came across an 88mm pro m MAF which says on it that it is calibrated for 19lb injectors. I have 19lb on my car still, and was wondering if I would get any decent performance boost from the 88mm maf. I currently have a bbk cai and free flow exhaust, as well as a jet stage 2 chip. I was told by several guys at the drag strip that an MAF upgrade is what I am missing. agree or disagree? the research I have done online shows mixed opinions. some seem to think it will cause detonation....(im thinking with the stage 2 chip reprogram that I will be fine)

again the sticker says it is calibrated for my stock injectors.

You aren't maxing the capacity of your stock MAF so I don't think an aftermarket one is going to do anything.

It won't do anything for your performance. You'd be taking a gamble for no benefit. Don't even consider it.

Correct!

The OEM 80mm MAF is good to 1150 kg/h (it "pegs" at 1220 kg/h) , which is 2535 lb/h of air. At 12.5:1 AFR, a bit rich for n/a, that 2535 lb/h of air would be mixed with 202.8 lbs of fuel, 202.8 lbs/h of fuel is 400HP+ for an n/a engine--which isn't going to happen, if running f/i it's still good to 335HP or so.

Tell the "several guys" at the strip they don't know what they are talking about...

hmmmm... ok thanks for the info.

I wonder why those dudes were so insistent on me changing out my maf. they both ran mustangs too. I think they were saying that with my CAI that the stock MAF body was the smallest and more restrictive part of the intake. Does that make any sense?

upgrading to a larger throttle body and plenum is a good idea though correct?

is there any reason to upgrade to a bigger MAF without changing the 19lb injectors?

I have an eaton m90 I was going to try and put on soon.

The upper plenum is the most restrictive component of the stock intake, with the TB being second--read more about this here. There is no need for a larger MAF for any n/a application.

I saw a company (bbk) on the internet who has a one peice plenum and t body. it is 78mm. will this be too big for my car and hurt output? I am hoping to put a supercharger that a bought on the car eventually and was hoping to "grow into" this 78mm. thoughts?

It won't hurt performance, it also won't help performance. as compared to any of the other after market TB/plenum combinations--unless you are running some incredible level of boost it's mostly a marketing gimmick...

I bet the OP wishes he could just memorize that and spout it back at the schmucks at the track that are living in 80's w/ the 5.slows
