Injected 408+ stroker guys.....MAF choice help.

[airbur]

For the guys running 408s or higher, what size MAF did you go with? I was set on the 80mm Pro-M but am now considering a 90MM. I am not worried about loss of torque etc as strokers tend to move the power band down. I'll be using 42lb injectors.....

Thanks.

Do you have a local tuner, thatmight be best person to ask. Rememeber that going bigger is for high rpm, not neccessarily more power low end, and will result in reduction in off iddle control as the size increases.

Yea.....was planning on a tuner after I get it all setup.

What ECU are you running? You'll need a Tweecer or Quarterhorse tuner to set it up. A good tuner is another five bills.

I have a 90mm and 42 lb injectors but have yet to install. Currently running 80 mm with 19 lb and it actually runs pretty good.

I currently have an A9L that I was going to try out but I've been talking with Pro-M about their custom unit:

I looks like they install a pre-burned chip. Might work.

They also remove all the HEGO codes I believe along with some other enhancements.

If you're going with a tune to dial it all in, I would stay away from the aftermarket MAF meters and instead go with a factory MAF from a Lightning, early 00's Continental or other Ford. Once the tuner knows what MAF you are running, they add that table to the chip. That is what I did on my 351 and 80mm Continental MAF. I've heard less than stellar things about all of the aftermarket MAFs.

Yea.....I've been thinking along those lines also. What cars had a good 80MM MAF?

I think the very commonly used Lightning MAF is 90mm. I used an 80mm MAF from a late 90's to early 00's Continental or Mark VIII. If you get an earlier one, it uses the same plug as a fox body mustang. It is a flanged MAF housing so you'll have to be creative or build a flange to attach it to. I ended up using the early 00's Continental filter housing that the MAF bolted right to. This is the one I have, posted C/L link to show pics & part # http://providence.craigslist.org/pts/3299608333.html
