Again, MAF numbers are not dyno numbers. You did not gain that much power from just a ported TB, ported IM, catback, and drop in air filter. And you are not at 485 HP to the wheels without a tune and LTs at the least. The mods you have are probably good for a handful of power at best. Maybe 10 to the wheels. And I highly doubt you added 3 tenths to your 0-60. Most likely you drove the car better that day and got better results. The only way to know what you have is to get it on a dyno and get it to the track.
Not for nothing, but do you say this stuff over on the Mustang forums? Do you tell them that your ported IM/TB, catback, and drop in filter has you at 485 RWHP based on MAF readings and that you're gapping GT350s by several car lengths from 40-85 rolls? How do they reply to that? Just curious.

I realize MAF readings are not dyno numbers. I was saying a general rule of thumb to
crank hp is 10 hp per lbs/min MAF reading (I specifically said crank hp in my post). I'm not saying with certainty that my car is making 530 hp just because my MAF readings are 53 lbs/min. But at 53 lbs/min it's certainly well above 460 (stock) hp. And I have the K&N CAI, not just a K&N drop in. And again I never claimed I gained 3 tenths 0-60. I said I improved my 20-70 mph time from 3.53 seconds with K&N CAI intake only to 3.28 seconds with the addition of the ported TB, IM, and Borla catback, and it's probably faster now because the car is another 60 lbs lighter (72 lbs if I remove the lower rear seat pad temporarily) since that round of tests. I do that 20-70 split because it takes the launch out of the equation giving better apples to apples comparisons. Having done multiple splits and looking at the data (again, prior to weight reduction), my car was seeing 0.05-0.06 seconds improvement for 10 mph segments up to 70 mph (over K&N CAI only). I guessed I could probably get 2 tenths out of my 0-60, though.
Just to be clear - I realize this isn't like going to a drag strip nor a dyno. However, those are extremely variable as well. Dyno to dyno could see large differences, just like at a drag strip where the 60' makes a big difference. But at least it's something showing improvements rather than just guessing because it "feels" quicker or more powerful (which it does). I just look at it as set of interesting data.
I posted about my upgrades and data on m6g. I didn't mention the roll races because those were recent and it hasn't come up. That thread was from months ago.
And my buddy's GT350 is not an R. So it's similar weight to mine, except he hasn't done any weight reduction at all so my car is lighter than his.
