silvrsvt Posted May 22, 2014 Share Posted May 22, 2014 This is from a buddies 2013 SHO he has, only mods at the time was an Intake and AM exhaust, besides the tune. Keep in mind this is also an AWD dyno too...but the numbers are impressive! 2 Quote Link to comment Share on other sites More sharing options...
fordtech1 Posted May 22, 2014 Share Posted May 22, 2014 Nice numbers. I know the EB has untapped potential. My concern would be durability. Not sure the transmission and PTU could take the extra power. The 6F55 has some beefy guts, but not sure what its tested for. Quote Link to comment Share on other sites More sharing options...
92LX302 Posted May 22, 2014 Share Posted May 22, 2014 I had a friend who ran low thirteen with a crewcab LWB FX4 with 35'' tires. That thing hauled ass. 1 Quote Link to comment Share on other sites More sharing options...

brucelinc Posted May 22, 2014 Share Posted May 22, 2014 While dyno numbers are impressive, what is really shines about a tuned MKS or SHO is the combination of drivability, fuel economy and performance. To me, a 4500 pound AWD vehicle with a 2.77 gear that does 0-60 in the low 4s and runs the quarter in under 13 seconds is almost freaky fast. The 27 MPG cruising mileage is icing on the cake. Of course, if driven hard, there will be more strain on the transmission. However, there are a surprising number of tuned SHOs that have dozens if not hundreds of dragstrips runs with absolutely no transmission issues. The 6F55 has proven to be pretty robust. I have never heard of a PTU failure on a MKS or SHO unless it was leaking and ran too low on lubricant. Not saying there are NO failures - just haven't heard of any. 1 Quote Link to comment Share on other sites More sharing options...
theoldwizard Posted May 22, 2014 Share Posted May 22, 2014 I know there are kits on the market that do water-methanol injection. F150s in the low 12s Quote Link to comment Share on other sites More sharing options...
brucelinc Posted May 22, 2014 Share Posted May 22, 2014 Nice thing about modding an F150 is that they do have a much more robust drivetrain than an SHO or MKS. The fastest SHO that I know of is in the high 11s in the quarter and uses Meth injection as well as a more aggressive tune than I have. I am happy with with way mine runs with just a fairly conservative 93 octane tune. I don't see crazy high boost numbers but the boost does stay at its maximum all the way to the shift point. When stock, the boost dropped back at higher RPM. Speaking of boost, it is surprising how responsive the 3.5 is in a SHO or MKS when not using boost at all. While not as much fun, you can easily keep up with traffic and drive way over the speed limit and never get into the boost. 1 Quote Link to comment Share on other sites More sharing options...
chucky2 Posted May 22, 2014 Share Posted May 22, 2014 There is a guy over at http://www.fordflex.net that is over 600HP in his Flex. No idea what it runs. 1 Quote Link to comment Share on other sites More sharing options...
SoonerLS Posted May 22, 2014 Share Posted May 22, 2014 The 6F55 has some beefy guts, but not sure what its tested for. 550 ft-lbs, per the "55" in the designator. Quote Link to comment Share on other sites More sharing options...
brucelinc Posted May 22, 2014 Share Posted May 22, 2014 550 ft-lbs, per the "55" in the designator. I don't recall how much multiplication there is in the torque converter but most of us with tunes are probably exceeding what Ford considers the safe limit. I think Ford is pretty conservative about this and rightly so. I cannot confirm it but the tuner that many of us use has said that the transmission will stand 700 lbs-ft before failing. They didn't say how many TIMES it will stand the 700 lbs-ft. - presumably just once. Quote Link to comment Share on other sites More sharing options...
SoonerLS Posted May 22, 2014 Share Posted May 22, 2014 (edited) I don't recall how much multiplication there is in the torque converter but most of us with tunes are probably exceeding what Ford considers the safe limit. Per the engineer who ran the calibration teams on the 5R55 transmissions for the LS, the torque converter can double the torque from the engine; what saves the transmission is that the TC's max multiplication factor and the engine's peak torque generally don't coincide. I took that to mean that the TC is locked up well before peak torque, but I might not have understood him correctly (my map of slushboxen internals is clearly marked "Here Be Dragons" ).

silvrsvt Posted May 22, 2014 Author Share Posted May 22, 2014 The tune has torque management still. If you shut off advanced trac on the SHO with a tune, it will seriously pin you into the seats! I nearly made my wife vomit doing that My same friend ran a 13.5 1/4 pass with the same car! While dyno numbers are impressive, what is really shines about a tuned MKS or SHO is the combination of drivability, fuel economy and performance.

fordtech1 Posted May 23, 2014 Share Posted May 23, 2014 550 ft-lbs, per the "55" in the designator. I wasn't sure if that was still the case. I realize the 6 is six speed and F was fwd. The regular NA 3.5/3.7 fwd applications use a 6F50. So the transmission rating goes from 500ft lbs to 550 for ecoboost? Interesting. Either way that Trans is a pretty good one. Minimal problems even when introduced. Quote Link to comment Share on other sites More sharing options...
akirby Posted May 23, 2014 Share Posted May 23, 2014 It's 550 ft/lbs but that's at the input shaft behind the torque converter. The torque converter multiplies the engine output considerably so it won't support 550 ft lbs at the flywheel. Remember the 5R55 in the Ranger/Explorer/LS/Tbird had the same torque rating.
