  1. unique tuning?

    Here's another way way of looking at your numbers You said you did a 7.9 100-120 (62-124mph for the rest of us) That means you'd do about a 9 second 60-130 which is about right for a full bolton Mustang on e85 A stock DH thats running really well will go 10.1 or so You're only up about 5 in...
  2. unique tuning?

    They added 'secret parts' which they didn't say what they are Do you have the secret parts?
  3. unique tuning?

    It's tuned so they both make the same amount of power according to the tuners....same engine except better rods/pistons (which don't matter at NA levels)
  4. unique tuning?

    Nobody said they add power. They free up power. Which the dyno sees as more power. More power to move the car instead of spinning around parts. Not sure why this is so hard to understand.
  5. unique tuning?

    Steeda made 487 on e85 with all the boltons plus ported heads (how much do those help? Probably not much with stock cams etc) You're 50 above that.
  6. unique tuning?

    They free up HP which makes them show more power on the dyno and go faster down the track
  7. unique tuning?

    Wheels and driveshaft might be worth 10hp on the dyno.... Anyways.
  8. unique tuning?

  9. Kooks Long Tube Headers Green Catted High Output 1 7/8''

    These would be great questions for the people at lethal. Why don't you send them an email or give them a call?
  10. Has Anybody Run a Larger Pulley?

    If you're having heat problems on the track I don't think lowering the boost by 2psi is going to do much The problem is you're making a couple hundred more HP than the cooling system was designed to handle The question becomes does the larger pulley physically fit. Is it going to run into...
  11. unique tuning?

    What's stock car make on that dyno, 490?
  12. 4:10 Gear - Would you do it again?

    It'd be nice if someone had some plots of torque in each gear. I tried but suck at Excel, would probably be best to do it in Python or Javascript
  13. 4:10 Gear - Would you do it again?

    3.55 vs 4.09 Top speed in each gear Includes both 2011-2017 ratios, and 2018+ ratios (MT82D4) Assumes 27" tires and 7500 RPM redline 4.09 3.55
  14. 4:10 Gear - Would you do it again?

    Which is why is said the T56 depends on which gear set you had...
  15. 4:10 Gear - Would you do it again?

    Can't really compare your Dark Horse as the ratios are completely different than the GT you might be closer to the T56 ratios you had in the 2006 (depending on if you had 2.93 or 2.66 fist gear...) but first is still going to be taller
  16. 4:10 Gear - Would you do it again?

    The ratio will actually be 4.09. doubt many people have done it on the S650 but the 2018 and newer cars have the same transmission ratios and 4.09 was done plenty of times, head over to Mustang6g.com and have a look https://www.mustang6g.com/forums/threads/2018-mt82-d4-4-09-vs-4-56.191848/
  17. Fair warning Steeda so called premium clamps ...🙄

  19. Whipple Calibration On Hold

    Do you know what mph you would end up at after 20 seconds of WOT? 7 seconds 60-130 then you have another 13 seconds to hit the speed limiter (if it's still there) or 180-190
