Granatelli adjustable MAF
Has anyone used or heard any results on the Granatelli adjustable MAF (for 85-89 TPI) over a stock MAF. I think my OEM MAF is a restiction. Thanks for your help!!!!!!!

I had that thing and returned it. It was a complete waste of money and did not even work.

I believe that the GMAF is no bigger in diameter than the stock MAFs. And yes, the GMAF is very expensive. The attraction of the GMAF is that it is "tunable".
If you are worried about the MAF being an air restriction, well it is. But you can remove both screens and have it flow 658 CFM as compared to stock flow of 518 CFM, that is an improvement of 27%.
658 CFM should be enough air to make about 506 Hp.
518 CFM should be able to make 398 Hp.
FWIW: I am using a descreened MAF on my 395 cu.in. stroker.
