  1. Whipple car runs bad - tune issues

    Since I installed my Whipple back in July, I have always had a problem with part throttle performance. Surging, hesitation, breaking up, etc. Just like running too lean. I found that the behavior is closely related to which gas I use. Since I live in NY, the gas here is all 10% ethanol and...
  2. Momo shift knob. One of the best mods yet...

    I have an MGW shifter which does without the pull-up reverse lockout collar. If your shifter still has this, this maybe isn't a thread you want to read... I have been unhappy with a bunch of shift knobs I've tried with the MGW including the stock one and a Ford Racing ball. The stock one I...
  3. WTB: Stock cats, both sides

    WTB. Stock cats. Driver's side including exhaust manifold and passenger side downpipe. John
  4. I done broke it!

    But, at least I got to ride in a tow truck! Broke a half shaft. Driving to work yesterday and nailed second gear - Bang! The car wouldn't move. At the time I figured I broke the DS or the output shaft in the tranny. My thoughts were that because I have the PP with the Torsen, that if it...
  5. Tricks and Tips: Clutch Line install/removal

    Having had my tranny out twice for clutch issues, I figured out a trick to make things easier. The clutch line is easy to disconnect from the transmission; it's really hard to reconnect. The problem is once it's disconnected, there isn't enough slack to reconnect it with the tranny hanging...
  6. Small $$$ Big Improvement - Shaker Pro upgrade

    Since buying my GT Premium PP a year and a half ago, I've been underwhelmed (being polite) by the sound quality of the Shaker Pro audio system. The main problem was muddy highs from the front 3 speakers and excessive midrange. The sound was so awful, I spent the past year either listening to...
  7. WTB Stock drivers side exhaust manifold w/cat

    Nevermind. Ordered a new one.
  8. HELP ME! Guru needed. Whipple running like poo. SOLVED!

    Help! I am having an issue with my car that I simply cannot pin down. The Whipple has been installed for a few months and everything was fine until about 2 weeks ago. On a WOT run, the engine started to misfire at about 6500 RPM and threw a P0300 random misfire code. I cleared the code and...
  9. Cylinder head removal - drivers side

    Anyone have their cylinder heads off with engine in car? I may have blown my head gasket. My Whipple supercharged GT has a bad misfire on cylinder 8. I am Mode fairly sure that's where the misfire is - the engine doesn't throw any codes apart from random misfire. However using ForScan's Mode...
  10. Whipple Stage 2 on Dyno Today :-)

    Scheduled time to have three dyno pulls on my Stage 2 Whipple car tonight. I was VERY happy with the results. Before I get into them, let me tell you a bit about the car. The engine is stock except for OPG and TG. The exhaust is stock except for an X-pipe. The Whipple setup is as it came...
  11. PP Radiator Braces.

    This is part of the chassis stiffening used in the Performance Pack Mustangs. I needed to remove this to accommodate the Whipple Intercooler. $30 shipped. John

  13. FS SCT X4, Unmarried, $200 shipped

    Went Whipple so I use the Flare tool now. Selling my SCT X4. It was branded by BAMA (see pic) but it is really an X4. I was using it with a Lund tune. John
  14. Gauge Mode Boost Display on GT?

    I saw this video on Youtube of a Paxton supercharged 2015 GT. [ame=""] His dash display shows vacuum/boost like an Ecoboost car. I want this!!! How is this done? John
  15. Whipple weirdness this morning

    I was driving into work this morning and was getting into the throttle hard. At the end of third gear the engine suddenly lost power. I pulled over and poked around under the hood and everything seemed attached etc. The car was idling fine. So Since I didn't see anything bad or leaking, I...
  16. What gears fit what diff?

    This may be a dumb question since as far as gears go my exposure has only been to GM 10 and 12-bolts. Done many gear changes. I have a GTPP with the 3.73 rear. Since installation of the Whipple, I find I want to go to a numerically lower ratio: say 3.31 or 3.15s. Will these gears fit on...
  17. Just installed my Whipple

    Tonight is a momentous occasion. After waiting 6 weeks for the Stage 2 kit from Whipple, I installed it along with a MMR OPG and TG. Upon starting it up and taking a quick drive, I noticed it kept throwing two codes P0390 and P0394. These are Bank2 Camshaft position sensor B. I remember it...
  18. Rear Cradle Long Blue Bolt PN?

    I had by cradle bolts out for the umpteenth time to fix a creak (cured using BMR lockout kit). One of the long blue bolts that holds the cradle to the underside of the car is bollocksed up a bit. I chased the threads and it goes in fine, but I really want to replace it. Digging through...
  19. Garden Hoses

    My Stang doesn't fit in the garage on account of my other toys. That being the case, I need to wash her quite regularly. I love the expanding/collapsing garden hoses but they just don't last more than a month or two before they burst. I have very high water pressure... I hate having to...
  20. Whipple Questions.

    My stage 2 kit is on order. Should be another 3-4 weeks before I get it - I can't wait!!! I never did get an estimated ship date, just different answers: 4 weeks, 6 weeks, 7 weeks... In the meantime, I have a few questions: 1) What is the process of getting the correct tune for the...
