Mine has been great besides a few mishaps and bad luck. Mine also has a custom intercooler so i had to work around that. Otherwise my jku pulls like mule in the low/mid range with 37's. Sprintex isnt horrible and this is a Bosch issue not sprintex

 

I'm confused courtsm3. I have been looking around at your posts. Aren't you selling your supercharger due to gas mileage decrease and mechanical problems?

Mileage yes, problems no. I was frustrated at first with the blower because with the intercooler and base tune, it wasnt running right. Then evap code, leaking line ( my fault ) , surging but im geared too high for this type of blower ( nothing wrong with the blower ), knocking but that was a tune issue that has been fixed, hose clamp broke on the inlet causing knock ( shit happens ) and loosing intercooler fluid causing knock after it got warm. All issues were never with the blower itself, it works perfect. rushed install and sloppy maintenance by me. Runs like a charm again but im pretty sure some of my shit mileage is due to a cracked manifold. Small i believe because when my jeep warms up its less noticeable. But im right around 13-14mpg right now, on 37's and 50/50 city/highway. Likely with winter fuel at the pumps still.

 

I see. Is the idle the same as when it was stock?

Idles perfect. Sounds badass at idle. I get a few lookers and talkers

 

Nice. Was it rough at all once you installed everything? I mean there is done relearning involved with the computer correct?

For a few days the supercharger would idle up and down slightly at a stop or slow roll to park. But yes the ecm smoothed it out. But those little blips were minimal.

 

What about Hennessy's supercharger:

Well I got a remanufactured engine for $2300 and it's $1000 for the install. $3300 is better than $5000 but when it's all said and done I bought the supercharger for $2300. The catalytic converter for $885. The labor was $550. Then the engine for $3200 and $1000 for labor. I don't even want to add that up! Sprintex go **** yourself!

Why did you get an engine? What happened since last night?
