Yes, I did do it myself. I did not read the directions before I took the front end off the car!! LOL So it shows I made a few mistakes like.. not running super unleaded in the car before the install! I had to use pictures off the internet to try and make sure I understood what the directions were trying to tell me. They are not bad, but could be better. I didn't want to mess up a 2013 so maybe I was too .. "I want totally clear instructions"... I bought the kit from Brenspeed.. the 650HP Kit.. It runs really well. I have 3:73 gears so 1st gear is pretty much useless,,,,, Shift! Shift! First tank I only got Avg... 9 MPG but it was fun..
I ran second tank and it ran well. BUT I just filled up with Walmart Super Unleaded and it doesn't want to idle for crap. Start the car up, then move. It will drop RPMs then jump then drop off and die. I slowed down to make a turn and the darn thing died on me. I just put in a couple of bottles of Octane booster to get me by. ( I had the same issue on anther car and it was doing the same thing -I was running to low of octain) It seems to help but its still finicky now. I will run it harder to burn fuel, ad a little racing gas..
Now I also have the cat deletes with Corsa Extremes so when I hammer down its loud!! (I like it) I just moved the rear tires to 275/40/19's and may need to go wider. Rear Axle tubes are welded, car lowered, new UCA, New LCA, single piece drive shaft, with 1st gen MGW shifter. When I launch it doesn't bounce like it did before but I need to go one more step for better hard take off's.
When driving normal you would never no it had a E-force. Car runs just as smooth as before. You do not hear the Whine until you get on it hard. As I told my Daughter the other day, the Supercharger is great but it will not make up for bad shifting. So will say its not a true Race style Super charger. I really don't understand why its the Same Eaton blower used in other brands put into an Edelbrock Aluminum case. Yes it is upside down Verses lets say the Roush but maybe my knowledge it too limited. Just like If its the same why can it run less boost? And so on.. As far as a Daily driver, non racer.. It was a fun thing to do. not a bad install, ( a few glitches- that were my bad) I took my time.. I have 4 kids- enough said! - took me about a week, solo, few hours a night. I would say the only thing you need help on is having someone help with putting the Supercharger on the motor. PS i have the 675 HP pulley and tune also so when weather if fully warm ill swap tune and pulley just because I can..
