Trying to decide if I should port my stock ends and whether I could use a saxon air straightener screen in it. What kind of gains could I expect? I have a FTRA lid and am getting a ported throttle body. I'd like to use an 85mm MAF, but someone said I would have to have to get a tune for it to work right. What do you guys think.
You will have to get a tune for anything you do with it. Leave it alone.
Unless you have a mid size cam and good ported heads it won't matter anyway. I went from stock MAF with stock screen to 85mm with Saxon screen and gained nothing.
I just ordered the saxon screen to replace mine that I tore out when I first got the car.
I don't have the coin yet to buy a FAST intake or bigger throttle body...but I'd like to do whatever I can to get more air in to feed the cam I just bought. I bought an Ed Curtis StreetSweeper 235/239...so I'm getting it tuned anyways. Just looking for cheap budget mods I can do until I do heads/intake/TB. With my cam and exhaust...I'd like to do anything I can to get more air in. As long as it's cheap!
So does anybody think it would hurt if I ported the stock MAF ends and used the screen?
Like I said I would leave it alone based on my experience. I gained nothing from a larger MAF on a car with a good size cam and mildly ported heads. It takes a bit before the stock one becomes the problem. And this is also with a Fast 90mm intake.
I just checked car-part.com, you can get a used MAF for $15-25. Buy one port it and if it causes problems you'll only be out ~$20. I remember watching a YouTube video of 2 cars with the same mods, they put ported MAF ends on one of them and did a couple roll races (I know ) the car with the ported MAF pulled over a car length on the other. Then they swaped the MAF's from one car to the other and raced again, the other car now with the ported MAF pulled a car length on the car that won the time before. I don't know how scientific any of that was but it seemed pretty convincing to me.
Also this picture makes a good argument for a ported TB.
