Gained 3 mph in 1/4 mile When i put on my FTRA and Granatelli MAF (both at once) i gained 3 mph in the 1/4 mile. It was consistent 107, and is consistent 110 mph now.
I wouldn't have even bought an aftermarket maf but i got such an awesome deal i couldn't pass it up.
I've read all about how the stock mafs are good to like 500 rwhp but is it maybe possible it contributed to the mph increase? Or is it just the ram air that helped?
Reason is, i might try to sell the MAF if its not really doing me any good...input please!

DSMers use 3 and 3.5 GM MAFs to way beyond 500WHP levels of airflow. I dont think it would be of much use unless you maybe had a 90/90 setup or the new Aussie intake for the L92 or whatever.
Im guessing it was track conditions more thn anything. But then, who knows. Maybe the new MAF is more accurately repoting airflow than you old one for some reason.

I would have to assume that most of the MPH gains were from the FTRA. I have the SSRA2 which is similar to the FTRA and I gained 15 horsepower on the dyno jet. My camaro aleady had the ported TB and the SLP lid and a small fan was blowing air towards the car's radiator. Check out the link below for the dyno graphs. I can't wait to take the car to the dragstrip as I think I will also run 110 MPH trap speeds with just the mods that I mentioned along with the good weather mod.
'02 A4 Z28 w/PTB dynoes@298...after SLP lid, dynoes@303...after SSRA2, dynoes@318!

i would have to say that you picked up mph from the ftra..for example my ws6 always trapped 109-111 with only a lid and catback yet my friends ss with the same mods traps 107..the ws6's have a much better ram air setup then the ss

I used to see a 1-2 mph increase with the SSRA when I had one.
1,2,3 mph increases from small mods are great, but weather/temps could have the same amount of impact on your mph.

A lot of tuners say it's really hard to get everything dead on with the aftermarket MAF's. Not to mention that it's creating a little more power because it IS running lean.
