we had a Roe on our 98 RT10 for 15 years, zero issues. plenty of long trips, Detroit, Salt Lake City, Charlotte, FL, etc.  Installer and tune are the key.
Yours being 2002, 5 lb boost is safe, more than that you’ll probably need water/meth, nitrous, etc. Loud depends on exhaust mods, most likely catless or high flow cats. Maybe others will chime in. But, I’d say do it if you want.

Agree with the comments from the previous post. I have a new generation ROE kit and have been very happy. 2002 non-forged internals will impact boost level and would definitely include a water/methanol kit. That said if MPG is a significant driver for you, not sure if you want to play with more horsepower. The only way to get more horsepower consumes more fuel. The type of driving (street/highway) and your right foot will determine the MPG. I have a ’99 so do not have the same boost limitations. I never got great mileage before – roughly 11 mpg around town and 13mpg highway. I am not Mario Andretti, but also not Driving Mrs. Daisy. After supercharging (14lbs of boost) 700RWHP, I get about 8 mpg around town and 10 mpg highway. Hard to say how 5 or 7 lbs of boost would impact. Clearly for me mpg was not a concern.

I’ve had my Gen2 RT Roe charged since 2007.  Still runs fine (other than it’s time for a new clutch now.) Tuning is paramount, but the neck snapping power of a roots blower is like nothing else.

Leave it stock why screw with it if your using as a daily driver, more HP more issues, more tickets, more chance of too much HP at the wrong time. Enjoy the car knowing that it has more HP than most anything  else . I have a G1 and a G5 I love the raw of the Gen1 and have no desire to do more and prove something to anyone.

Truthfully, it comes down to where you live or how far you’re willing to ship your car. Not changing the exhaust is going to rob you 30-60 whp. It is difficult to come across Roe kits anymore. My advice would be the Paxton. It seems that the Paxton cars have less cooling issues compared to Roe cars. Either way I would highly recommend a watermeth kit as well. Regardless you run the risk of snapping the crank pulley. If you do decide to supercharge it do not throw on a DLM tensioner. Out of the 3 snapped cranks on supercharged cars that I have seen in the last year, I believe all three ran that tensioner. The other thing is the tuning. A lot of people do remote tuning, I can say that it costs more and it never seems like you get the same drivability that you would if you had the car tuned in person at a shop. I have two Paxton cars myself. The Paxton with the stock bypass valve is depressingly quiet, which sounds perfect for what you’re looking for. I upgraded mine to the Vortech Max Flow Race BOV so I could actually hear the supercharger.

I developed that kit with Paxton and installed over 50 of them on the cast piston Gen 2’s.

Feel free to reach out if you need any advice.

Do belanger headers if you dont have them already thats an easy 50hp upgrade.. you could put a cat and muffler behind it that isnt too loud or droney i suppose. I think stroking and a cam upgrade might give you the power you want vs supercharging though.
