Yeah, I was at around 24 highway... City driving and a few 2nd gear pulls brought it down to 20.5... Hell though! That ain't bad! My last car C63 AMG Mercedes got 8-12. LOL

Hey guys! I was pleased to see that after a day of driving on my Roush Phase 2 upgrade (city and highway) I stayed over 20mpg, and I wasn't driving her easy! I also have a mt82 w/3.31's! WHATS YOUR SUPERCHARGED S550 GET? Let's all share!

Yeah Kyle! I figured a fix is in the process. It happens so rarely, I never really sweat it.

It has happened to me in 6th gear when I throttled down without down shifting, and it happens sometimes on ice cold starts if I don't let it get warmed up enough. It's a huge power adder, so I figure I blame it on "racecar" if we are going to add this and pulley off that, etc, etc, I'm sure...

When do you get it exactly? I was having wrench light at a few key times only. Surprisingly enough, when I swapped out 3.73's for 3.31's it stopped doing it at those key times.

Roush phase1 will get you there!

Congratulations man! You will love it!! The phase 1 670 tune is plenty enough for you for now. Hell, I went 10.8's on street tires on my phase 1 only setup, right off the dealership floor!!

:headbonk::headbonk::headbonk: What?? :headbonk::headbonk::headbonk:

I need this in my life!

Its not the price difference that concerns me. I've had local friends tell me they wouldn't go RXT without getting the trans strengthened/rebuilt.

Yeah, its a toss up for me still kind of.. I don't plan to exceed 800whp so the RST should be ok with my mod plan I would think. But what do you think the most benificial difference is between the two clutches?

I've had nothing but the best of experience in my roushcharged car and wonderful interactions when working with Roush Performance staff. The reason phase 2 took so long is because they are adamant about vigorously testing their products before releasing them to the public. I was over anxious for...

Yeah, i'm sure the clutch will go this season on tire. I'm choosing the McLeod RST Twin Disc 800HP Clutch. I've heard the RXT needs a stronger trans behind it..

That last quote from Jack Roush Jr makes me smile!! I think he was talking about my car. :first:

This story makes me smile! :) Since i have been a Roush owner as well, i have been very impressed with their customer service and professionalism. They truly do set the industry standard, IMO!

Last season i ran all year on Roush phase 1 supercharger kit and Ford Performance half shaft upgrades only... Here was my best video documented pass on just a supercharger kit and street tires... [ame=""]

The tires that i ran these 10's on were General Gmax all seasons. pZeros are worthless! My best pass on pZero's wan an 11.2.... I lower tire pressure to 18-19psi, do a 5-7 second burnout, and leave the line around 1800rpm. You can see in the video how the car bobs shortly after i launch...

I decided to swap 3.73's for 3.31's in my mt82 forced induction setup. I have the Roush TVS though. I haven't made any 1/4 mile passes since the gear swap but it seems to be an improvement and i know it will keep me out of 5th in the 1/4 mile. Which is great! I had alot of fun on the 3.73's as...
