Another 4.6 guy over here.

My 0-60 is closer to 10 seconds I think ! :yikes2: :disbelief:

Also on a 6" lift, and running 3.73 gears, true 35" tires load range E (heavy SOB's !) 18" rims, and no real power mods yet. Too many other projects going on right now. :shrug:

If its dry when I get home, might hop in the truck to see what I can get. Been awhile.

5.4 in mine and did a 0-60 run got a 8.6X with 35's and 3.73 gearing yet the tire size was set at 23XX which is wrong so it should be better.

What altitude are you guys at? I'm at 5000 feet and I could only muster a 9.04 sec 0-60 time out of mine with my current mods. :cry-blow: I need some custom tunes pretty bad, but then again I only have 5200 miles on mine right now. Will it be substantially better once I get near the 15k, 20k mark?

I never checked my 0-60 or 1/4 times. Perhaps when I get my programmer back I'll try a few runs on stock, and one of the performance tunes. Just have to think of where I can get some open road...requires a little drive to the farm lands to get away from traffic.

BlackSTX, if you get me some 0-60 times I woudl surely appreciate it or anyone else for that matter. Mine seems really slow, even for a stocker that seems pretty slow, so I am curious what others are running. Thanks:thumbs up yellow:

Just 2 more days and I can finally place my order for the Gryphon. Seriously can't wait.

Best 0-60 as of right now is 9.12 on Gryphon stock level 2 but I can't find a place to do it without getting major wheel spin which makes my foot let up a bit without me thinking. :evillol:

Once I get as much of this 87 octane out I'll be filling it up with 94 and setting it to level 3... then I might have to buy some new tires... :whistle1:

Oh and the belt chirp is awesome at wot when shifting. I have never owned a vehicle that was as fast as this thing is now. I forgot I had a V8 under the hood. I used to have a 1976 Chev C20 with a 350 and my little 281 Windsor out does it hands down now. :2thumbs:

I checked mine, I am getting 7.63 for my 0-60. Im running a custom level 2 and have 33" Load range E. Does anyone know how to convert your tire size to the (mm) on the gryphon? When I do my conversion of 33" to mm I get 838.2mm. Something that I am missing?

Sure - the 838.2 is your tire's diameter in millimeters. You need the circumference, so multiply that by pi, which gives you 2633.3 mm. But then, deduct some for "squish" (often about 3%) so multiply by 0.97 and you'll have 2554 mm, which is the size I'd try.

If at all possible, use the manufacturers website to determine the "Rev per Mile" rating of the tire. Then to convert to millimeters, use this formula...

1609344 / Rev per Mile = Tire Circumference in mm

That helps eliminate any guesswork. :D
