Just installed the RIPP MODS ... Supercharger !!!!!!
I noticed that today driving in town !! What a JOY to drive !!!
I talked to Ripp Mods today and they said that as the SC and Electronics " broke " in the economy would increase ..... I have noticed a slight increase so far like 2 mpg !!! I will keep everyone posted
I noticed around a 2mpg on the highwayh increase, didn't notice it to increase much after the first couple hundred miles. But to tell you the truth, I don't stare much at the mpg to give you exact #'s so it may have increased from 2mpg to 2.3 mpg in the last few thousand miles, I wouldn't notice though. One thing that I did notice is that when comparing a 4dr with 5.13's and 35's, and my 4dr with 4.10's and supercharger, both going pretty much the same speed the whole time, the 4dr without the supercharger had his tank on empty when mine had about 40 miles left in it.
That is not quite the 6 mpg city and 11 mpg hiway that was advertised !!???
Do you have auto or stick ???
Found it .. it was on the Ripp Site :
The Dyno curve is very linear, with the power curve found in a usable RPM range, especially from low RPM. When used in 4W-low the power is instantly available and completely manageable. Daily Driving an SDS powered Wrangler is like driving a V8 powered vehicle without the poor gas mileage and acceleration is no problem, getting up to highway speed in no longer a task. We initially tested with two RIPP Powered Wrangler’s; our in house Wrangler X Unlimited with over 36kof supercharged miles on 35" tires and 5.13 gearing still runs like a champ. The other running in Rough Country Suspensions corporate vehicle a 07 Rubicon Unlimited with over 14k of their own. RIPP has recently acquired a 2008 Rubicon Unlimited and finalized testing in June of 2008 with an additional 4500 miles of testing, making the kit fully developed. These tests finalized our electronics and long term fuel trims. We are happy to report gas mileage has gone up nearly 6 miles per gallon in the city and over 11 highway WHEN DRIVEN respectfully for more info please email mailto:tech@rippmods.com
The last sentence .... of course " when driven respectfully " ..... I have to admit it is HARD !!!
