  1. The Saga Continues...Mantic 9000 Clutch Install Issues

    Something that stuck out to me as very odd is that the alignment tool would get stuck as the cover bolts were torqued. I mentioned that to Geoff and he said that's a first, but suggested there's a good probability one of the disks is warped / manufactured incorrectly or possibly the flywheel...
  2. 2018 Mantic Clutch Noise

    I'm in a similar boat with my 2016 PP GT. I have a 9000 twin disk organic after my OE clutch let go 4 weeks ago at 30k. The workmanship is stellar, well at least the billet machined parts appear to be. But it appears mine is over engaging AND the disks are NOT sliding across the splines like...
  3. The Saga Continues...Mantic 9000 Clutch Install Issues

    I'm not one week 5...still not Mustang...still no working clutch. I'm NOT happy with the 9000 I purchased for $1,500 from Lethalperformance. I'm not suggesting it's their fault as they didn't design the clutch, Mantic did. I tried calling Mantic USA several times over the last couple of days as...
  4. The Saga Continues...Mantic 9000 Clutch Install Issues

    Install is pretty simple, 8 bolt billet flywheel with 8 ARP hex bolts, 8 drive studs / bolts / nuts / lock washers, two sprung hub clutch disks, one intermediate sprung billet steel pressure ring, one front ridged pressure ring and one billet aluminum cover with a diaphragm style spring. Fist...
  5. The Saga Continues...Mantic 9000 Clutch Install Issues

    I posted about 4 weeks ago that my stock clutch let got at 30k. I don't drag race the car (not sure if the previous owner did as it had 5,600 miles on it when I bought it, but it was stock other than a Corsa exhaust and window tint). I've since made quite a few changes to the car myself. Power...
  6. Two 19x11 Square Setup Installs

    Anyone running corrected roll center and bump steer with 305 square setup? I figure for actual track work I'll probably buy a dedicated set of 6GR Ten Stain Bronze 19x11 ET50's with 20mm spacers up front and run some sticky track tires like the CUP2's from the PP2 or something similar. I love...
  7. 2015-17 Mustang GT Ford Performance Power Packs

    Also been mulling something else over. Power Pack 3 with intermediate 3.91's and 275/35R19 on a lightweight wheel setup. All of the track focused Mustangs run 35 or 30 series tires in the 26.3 to 26.6 diameter range (and of course much wider). Lower profile tires = lower CG without messing with...
  8. 2015-17 Mustang GT Ford Performance Power Packs

    I've been mulling over something like that myself, thanks for the up front work. Time to copy copy copy! I think that setup will work extremely well weather you have the stock hood vents or track spec hood vents, but also it should work very well with the VelossaTek RAM air duct if you do my...
  9. What diff fluid are you running for HPDE ?

    Thanks. I already use TriboTEX DLC coating in my 2nd gen 5.0, so I'm familiar with the use of ultra low friction coatings in engines. Works extremely well with MoDTC and the organic zinc compounds used in PU/PUP oils. Same additives are in PUP 0W-40 as in 5W-30 I'm currently running, just the...
  10. What diff fluid are you running for HPDE ?

    Also, I wonder if https://www.redlineoil.com/75w110-gl-5-gear-oil their 75W-110 would work well. It's just a little more viscous than 90, but not as thick as 140. Kind of like stepping up from 5W-20 to 5W-30. I'm always of the mind set of lets go with a fluid that is just thick enough, but no...
  11. What diff fluid are you running for HPDE ?

    Full Tilt Boogie has a lightweight diff cooler setup for $1k. Only 12 lbs for the whole setup (pump, radiator, fittings etc.) as I asked them how much it weighed. That's something I appreciate about the SS stock setup. All of the Alpha based SS's have oil to water cooling lines in the diff from...
  12. Another lost traction on freeway thread

    IRS movement is the big culprit on the S550's instability in certain situations. It's not the spring / damper rates or factory roll couple setup nor the tires. The IRS creates a lag / rubber band effect in stock form. That's why MotorTrend noted that hanging the tail out without it letting go...
  13. Aero Setups for Dual Purpose Cars

    Looking for recommendations on Aero setups for a 2016 PP GT for light duty road course work. The car is as the title states a dual purpose car and will see occasional track, but is mostly a street car. I'm not looking for an ultra high down force setup with lots of drag, so I was thinking front...
  14. 2016 mt82 issue or just clunky as always.

    I doubt the transit connect has anywhere near the power of the 5.0...unless they are running a newer Ecoboost V6 High Output....which again I highly doubt. Different application entirely. The best budget solution is aluminum shifter arm bushings + Motul DCTF. Ford Performance and Full Tilt Boogy...
  15. 2016 mt82 issue or just clunky as always.

    ^^ This. Not sure why everyone obsesses about BG. It is a manual transmission fluid with a 75W-80 viscosity. DCTF fluid is 75W with a hot viscosity of about 7 to 9 cSt at 100C, not 80! Both Getrag and Temec specify DCTF or Automatic transmission fluids for their manuals. The only thing your...
  16. 4.09 vs. 3.73 opinions wanted

    Also might want to consider 3.91's for Power Pack 3 (7450 rpm rev limit): 3.9 Effective Ratio Speed 1st Gear Ratio 3.657 14.908 ↔ 41.2 MPH 2nd Gear Ratio 2.430 9.906 ↔ 62.0 MPH 3rd Gear Ratio 1.686 6.873 ↔ 89.4 MPH 4th Gear Ratio 1.315 5.361 ↔ 114.6 MPH 5th Gear Ratio 1.000 4.077 ↔ 150.7 MPH...
  17. 4.09 vs. 3.73 opinions wanted

    4.09's would be a blast with the Power Pack 3 and a little more ideal due to the added rev range than with Power Pack 2. Torque curve is much flatter with Power Pack 3 than power pack 2 making throttle modulation more ideal with the shorter gearing. Power Pack 3 with 4.09's would provide...
  18. Another Exploded Clutch

    BTW, the organic material on the OE clutch I believe is a standard woven non-metal backed organic (silvery appearance) where the Mantic disks use heavy duty metal backed organic (coppery appearance) which has a higher temp rating, up to 700F. It's a great material for a street performance car...
  19. Another Exploded Clutch

    Good point on the gyroscope, I misinterpreted the axis of motion. But I disagree on the inertia of a well designed twin disk clutch. Case in point: OE 10" single disk clutch pack (pressure plate, clutch disk and hardware) weights 24.6 lbs according to a SVT thread by someone who actually...
  20. The "what things weigh thread."

    Didn't see these on the forum when I did a search so I figured I'd add them: 1. Mantic 9000 lightened billet steel flywheel with ARP bolts all still in the plastic bag = 15.5 lbs on my scale 2. Matnic 9000 twin disc organic clutch pack (pressure plates, spring hub aka the red thingy, bolts and...
