Humble Rumble Posted January 11, 2017 Share Posted January 11, 2017 (edited) Bumping this to share my results from XRT tuning so far. Surprised and very pleased with the power I'm putting down already, wasn't honestly expecting this high yet. This is from a 3rd gear pull. Very pleased with how the car feels currently. This is only my v1 revision. The car pushes my neck back off the line, and the pedal is much more responsive, and I feel like I have more available power throughout the gears. Ed also gave me stage 2 transmission tuning, which has tightened up gear response immensely. Only power mods so far are AEM Dryflow filter and Nameless 5" Axleback. http://www.xtremeracingtuning.com/forum/viewtopic.php?f=101&t=698&sid=6f2546cf785d2fac5c6db6d7b992eac9 http://i.imgur.com/00l4mzz.png Edited January 11, 2017 by Humble Rumble 2012 Legacy 3.6R Build Thread 5th Gen Legacy BM/BR Body Kit Compendium Thread Link to comment Share on other sites More sharing options...
BBPeik Posted January 11, 2017 Author Share Posted January 11, 2017 Nice too see some 3.6 results. I am very interested to see where you end up with your xrt tune. Thanks for sharing. My someday I will be done with it thread. Link to comment Share on other sites More sharing options...
mcg_ Posted January 11, 2017 Share Posted January 11, 2017 Also here's the numbers for the EL headers on the stock vf54 https://www.instagram.com/p/BJ5N7LjAWVi/ How accurate do ya'll think this is? Link to comment Share on other sites More sharing options...
jackal8788 Posted January 12, 2017 Share Posted January 12, 2017 Well, what the hell. I don't have the car anymore, but FWIW, it pulled like a beast with the 18G, e85, and the EWG. If you need to know my mods, there's a 50+ page build thread that can help you out! VF54 to 20G to VF54 to 18G build thread Link to comment Share on other sites More sharing options...
Timothy.B Posted January 12, 2017 Share Posted January 12, 2017 (edited) So, I had a long discussion with Ed from XRT today and he did some explaining of all these graphs and my head simply imploded. Ed uses two ways to display power graphs. One is reliant on the VSS (vehicle speed sensor) He inputs all sorts of variables and measures power differences this way. The way it was explained to me, one he's been using for years so he continues to use it to show comparison to other vehicles. While one follows the Volumetric Efficiency curve. These work great for showing differences with the same car. http://i.imgur.com/AuzGP3T.png You also have differences in gearing. Then you have the usually inflated dynojet numbers: http://i.imgur.com/Jp7mDCA.png Variances like air temp, pressure and humidity all skew measurements as well which makes it all the more difficult. These can be calculated in for more accurate results which works for the most part. Closest to the real curve that we can get: http://i.imgur.com/dW1oxSd.png If you were to stretch it out it'd look pretty similar to what Fredrik and Perscitus posted from their dyno results. Huge torque low, then torque converter lock, magic happens then power comes out. He believes this would be closet to actual power. Maybe slightly lower. Somewhere around 230whp. This is where aftermarket headers help. Increased low end torque to smooth out the dip and relieved back pressure at the top for more HP. Cool stuff. So many variables that comparing results to other cars is difficult. Neat stuff, none-the-less. I probably just made this way more confusing...hopefully this cleared some things up.

mcg_ Posted January 12, 2017 Share Posted January 12, 2017 Thanks for the info folks but my fundamental problem is that we, as a community, are so relatively small that very little before-and-after single variable testing has been performed. In this case, for instance, I don't think anybody (besides perhaps iq_performance) has been tuned & dyno'd before/after only changing the exhaust manifold. The iq_performance's post seems to indicate that a stock(presumably tuned) car can gain 37 hp and ~80 ft-lbs by simply changing the header. I wanted to know if that is accurate for an otherwise stock car? Overall, I wish we had a nice flow chart of stock turbo upgrade paths beyond down/side/J-pipe (mostly, because I'd like to know exactly what to do next). Basically, I really just like fahr_side's brain to be algorithm'd into a nice and tidy flow chart. For instance, would it be more beneficial (dollar/hp) to buy an aftermarket exhaust manifold or TMIC? Link to comment Share on other sites More sharing options...
FLlegacy Posted January 12, 2017 Share Posted January 12, 2017 Thats easy, FMIC...next question please...lol. You are right, there aren't a lot of before and afters, but understand that is only an incomplete picture. What is your goal? Link to comment Share on other sites More sharing options...

I wanted to know if that is accurate for an otherwise stock car? That's gotta be stock vs tuned with the header. I just can't see the OEM manifold being that much of a restriction...

FLlegacy Posted January 12, 2017 Share Posted January 12, 2017 I am pretty sure a cobb ots tune will also give you similar numbers vs stock. Link to comment Share on other sites More sharing options...
Golferdude1087 Posted January 12, 2017 Share Posted January 12, 2017 I am pretty sure a cobb ots tune will also give you similar numbers vs stock. It happens on a H6 raptor car to a greater extent bc it's freeing so much flow, it's also an 87 to a 93 tune so A lot changes Sent from my VS986 using Tapatalk Link to comment Share on other sites More sharing options...
Rutchard Posted January 12, 2017 Share Posted January 12, 2017 I am pretty sure a cobb ots tune will also give you similar numbers vs stock. Sounds about right. The only reason I can think of to change the OEM manifold is if you go EWG or if you're getting some custom manifold to mount a larger turbo down there... It's great that a company wants to make new parts for the 5th gen, I just wish they were making a useful part. Link to comment Share on other sites More sharing options...

Yup It happens on a H6 raptor car to a greater extent bc it's freeing so much flow, it's also an 87 to a 93 tune so A lot changes What happens on an n/a motor doesn't apply here. The turbine and turbine housing are far more restrictive than the header. The iq_performance's post seems to indicate that a stock(presumably tuned) car can gain 37 hp and ~80 ft-lbs by simply changing the header. I wanted to know if that is accurate for an otherwise stock car? Not a chance. Overall, I wish we had a nice flow chart of stock turbo upgrade paths beyond down/side/J-pipe (mostly, because I'd like to know exactly what to do next). Basically, I really just like fahr_side's brain to be algorithm'd into a nice and tidy flow chart. For instance, would it be more beneficial (dollar/hp) to buy an aftermarket exhaust manifold or TMIC? Will it hurt? Can I have my brain back afterwards? That's gotta be stock vs tuned with the header. I just can't see the OEM manifold being that much of a restriction... This Thats easy, FMIC...next question please...lol. Easier than making a hood with a WRX-sized scoop, which is a part I wish someone would make. I asked Varis but they flat-out refused. Not because the market isn't there, but because no one is racing this model. Funny how a maker of ricer body kits cares that much about racing.

ChrisCrash Posted March 14, 2017 Share Posted March 14, 2017 Finally got around to creating a virtual dyno of one of my pulls after flashing to the cobb stage 1 93 map. I just purchased an etune so once the temp hits 65 I will be resposting my pre tune and post tune maps. Link to comment Share on other sites More sharing options...

Timothy.B Posted March 15, 2017 Share Posted March 15, 2017 Dynojet figures for my 3rd Gear. The H6 is definitely a very different engine. Hopefully will be able to meet up with a local LGT guy here and we can see the differences in person. http://i.imgur.com/8pkRD7Q.jpg Timothy.B's 2011 LEGACY 3.6R Link to comment Share on other sites More sharing options...

Humble Rumble Posted December 21, 2018 Share Posted December 21, 2018 I can share mine. 228.49 whp on a Dynojet. Power adder mods are: -XRT Engine & 5EAT Transmission Tune -Nameless Performance 5" Muffler Axlebacks -AEM DryFlow Air Filter -HKS Intake Funnel This translates to roughly 284 crank hp, roughly 30 hp up from stock. This was also run on 19x8.5 wheels with 245/40/19 tires, so larger diameter and heavier than stock. Because of that, wouldn't be to far of a shout to think that my real power rating is somewhere in the 290-300 crank range. 2012 Legacy 3.6R Build Thread 5th Gen Legacy BM/BR Body Kit Compendium Thread Link to comment Share on other sites More sharing options...
BBPeik Posted December 22, 2018 Author Share Posted December 22, 2018 I really should have a dyno run, but heck if I ever actually will get around to it. I plan on going to the 1/4 mile this spring and seeing how I do. I may do a dino tune before that to make sure everything is ok. My someday I will be done with it thread.
