  1. Florida 2018+ Used Roush Phase 1 Supercharger Kit FS $3200

    This kit was removed from a car that was involved in an accident. Some things were damaged in the collision such as all wiring harnesses and some cooling hoses. Other items such as the electric water pump and brackets, various cooling hoses, dagas tank, throttle body module, drive belt, and...
  2. Roush 12psi vs Whipple 9psi

    VMP just posted a video about supercharger displacement comparison. This is an extreme example, but still at the same boost levels.
  3. Roush 12psi vs Whipple 9psi

    From my personal experience with a roush 2018 phase one. With 12.5 psi I make more peak and midrange torque due to higher boost. Peak horse power on the roush is limited to supercharger inlet size and inefficiencies of lower manifold design. The two kits seem on average seem to make the same...
  4. THE NEXT BIG THING HIS HERE! 1003 RWHP ON PUMP GAS!!!!

    I was curious about this too. So I did a little math. Using a BSFC of .50 for 93 octane at 1000 hp gives a fuel consumption of 500lbs an hour. (Hp x BSFC = FC per hour) Assuming the direct injectors are at there safe limits on E85 with a BSFC of .70 the math shows the system will only...
  5. 6spd 2018+ gearing with edlebrock 2650

    I have a 2018 roush car with a MT82D4. One thing to mention is what will your expected horse power be. When I tuned my car to the 650 to 680 whp, I knew that I would trap around 130mph. With 3.55 gears and the stock Michelin 275/40/19 (which is a 28 inch tall tire) I was only at about 5600 to...
  6. 2018 A10. Whipple Stage 1. Ford time at the track.

    Sweet runs! I’m looking forward to similar conditions here in Florida further into the season.
  7. New PB finally some BOOST weather!

    No still have the stock axles. No rear suspension mods either. I wanted to find out if I could get the car into the 10s with just a power adder and tires. Unfortunately the factory twin disk just won’t hold the power. A McLeod RXT fixed that problem. The clutch has about 30 passes on it now...
  8. Question for guys who actually have the the Roush Kit

    Hlfbkd420 and I were talking about an easy way to turn on the factory fans and the IC water pump with out the engine running. If you were at a track with a nominal temp around 50 to 70 degrees. A Roush with an A10 would have to run 10s with IC water that is at least close to ambient. Ice tank...
  9. New PB finally some BOOST weather!

    I’ve been waiting for Florida to finally cool down a bit. Was able to take my car to the track with the temps in the high 60s. What difference when battling on a 95 degree day. I gained two tenths and 6 mile an hour just from a 30 degree ambient temp change. I hit my goal of a 10.80. If I...
  10. Question for guys who actually have the the Roush Kit

    I dropped the roush h/e. I was going to experiment with valving to attempt at retaining it, but I decided it was too complicated. I just run the a/c all the time unless I race. The car should shut the compressor under wot, but I haven’t verified this. When I’m cruising around town or on the...
  11. Question for guys who actually have the the Roush Kit

    Yes sir. I swapped the rear gears from 3.55 to 3.73. It traps in forth at about 6300 rpms with a 26 in tire. I’m thinking about going to a 28 in tire and 4.09 gears.
  12. Question for guys who actually have the the Roush Kit

    Finally the stars aligned and Bradenton Motorsports Park had a track event last night during Florida’s first cold front of the season. 65 and dry for track conditions. Well this commanded excellent performance from my car. Definitely the fastest I’ve ever felt the car run. I used ice to...
  13. Question for guys who actually have the the Roush Kit

    @hlfbkd420 I’m sure you are not wanting to buy anymore tools to help diagnose your problem. One thing I would suggest to help is buying an infrared temp gun. I would shoot the heat exchanger and various coolant pipes to determine what your Intercooler water temps are doing. Would good to...
  14. Question for guys who actually have the the Roush Kit

    This is a really good point. I tuned at least 5 to 10 turbo cars before I started working with my car. Font mount Intercoolers may not not be the most efficient, but they don’t heat soak. I could be on a dyno with a fan on the IC between pulls and not worry. Within 5 min a 500 hp car would...
  15. Question for guys who actually have the the Roush Kit

    The kit supplied 500cc nozzle. For the power I’m making, this may not be enough. AEM has there own chart and I’ve seen others. I’m still working within the roush factory calibration. I wasn’t looking to gain power from the W/I. I was hoping for a bit more stable power production.
  16. Question for guys who actually have the the Roush Kit

    I’m running this exact setup with my car. So far not much change in a IAT2 temps possibly about 5 degrees less. I’m injecting just before the throttle body. I started with a 50/50 mixture and now I’m at 100% methanol. Of course I have no way of tuning. On a dynojet with it’s A/F sensor in the...
  17. Question for guys who actually have the the Roush Kit

    You have to install an aftermarket one. I built this one to replace the original from roush. The “degas” container does not flow enough water nor could you get enough ice in it to make any difference. This is my setup along with a chiller.
  18. Question for guys who actually have the the Roush Kit

    Lucky me 1000th post... Roush factory tune should have a 155 mph speed limiter. I’ve hit the limiter on the dyno every time in 4th gear MT82.
  19. Question for guys who actually have the the Roush Kit

    Doesn’t the Edelbrock kit run less boost also? I’m consistently running 12 to 12.5 lbs of boost on the roush phase 1. That’s good for about 610 lbs ft of wheel torque on my car around 4000 revs. (with a chiller of course) I haven’t seen a dyno chart on the Edelbrock stage one kit with torque...
  20. Question for guys who actually have the the Roush Kit

    @hlfbkd420 you are making a good observation based upon watching the activity of your fans. You don’t even realize it, but you are heating up the Intercooler water just by allowing the engine to cool. The Intercooler brick acts like a big heat sink By soaking up all the ambient heat from the...
