Stillen Supercharger reliabiity

irondoc

Thanks shovelman. I will look into this. Has anyone else here heard a recommendation for increased flow fuel injectors with the Stillen SC kit?
Are you recommending this as a way to get more power from the car, o as a way to stop the stalling problem, or as a preventive measure against future problems?
Thanks

The car went back to IPS over the weekend to sort out the stalling issue. The shield that covers the Air flow sensors had to be modified to fit the 2013, but when put in place the stalling was nearly completely gone. IPS also slightly modified the tune to increase fuel flow at idle. The car runs perfectly now - no stalling. I am very pleased.
Of note my last tank of fuel was 15.85 gallons topped off. I got 290 miles out of that tank The trip computer read 43mph average.
The trip computer also read 28mpg for that tank, but 290/15.85 = 18.3 mpg.
So don't trust your computer to tell you your mpg with the Stillen SC in place, it way overestimates.

It's basing its calculations on a smaller set of injectors. Any time you change the injectors you throw off the mpg reading. I get around 18 mpg combined driving and my display shows almost 30 mpg. I just switched the display to outside temperature. I'd love it if someone figured out how to reprogram the car to account for the larger injectors so I can have it work again.

I recently got my stillen supercharger. 408whp and 305 torque. Dyno numbers also vary with ambient temp. These numbers were at about 75 degrees with 50% humidity. I also am stock except for supercharger. I cant wait to get a hfc and cbe. With those i'll be getting in the high 400's and mid 300's with torque.

Irondoc it sounds like your pretty happy with your car. I have a new 2012 with 1800 miles on it and I'm thinking about pulling the trigger on this SC. I read the entire thread and there are many opinions and issues. It seems though, that most are not happy because they want more and more power. Thats great, but I want to maintain the factory block, and it cant handle much more than 400WHP for any length of time. I live down in Texas so summer heat may be an issue, and I have to check into that more. But if I can get around 400WHP out of this small car, I know I will be happy and stay alive a few more years lol.
On MPG. Who cares? If your putting the power to the car and your spending the money for it, who cares what the MPG is.....
Like you, I want a clean new car with much more than factory HP in a new car package. I will keep an eye on your feedback regarding your install.

Such a misinformed post. You have a lot of reading to catch up on. Power n longevity depend on how good your tune is from your tuner. There r guys out there with 500hp+ running for years just fine with no problem. Read up n research...

Coon-azz

That may be, but is this something they drive daily, or is this 500 HP beast a weekend warrior that only sees pavement when its 75 degrees, no rain, and etc etc? If you are going to critique troubleshooting/research methodologies, make sure you also compare "apples-to-apples". Though, I agree with your comment about researching 100%. The reason I say this, is because I've met many people who claim "no issues" with max HP builds, but what you don't find out till later is that this is a trailer queen, or they only average about 5,000 miles a year on the car. If it’s a daily driver through all kinds of environmental situations and they still maintain stock drivability, now that's a testimonial. If its a 1 day a week ride ,then no, I' dont think the feedback is comparable.

Well uhh you could find out if they're DD their Z or if its a "trailer queen" by researching... Off the top of my head I think I can think of 3 guys that DD their Z. I have a stage 2 Gtm that I DD and its over 500+hp. There's nothing wrong with daily drivin a boosted Z. If you have a good installer n a good tuner the Z will last quite a long time with double the horsepower.
The statement made earlier was simply some guy too scared or unwilling to put the money needed to boost a Z correctly. No need to try to spoil it for others with posts that a boosted Z won't last or give a lot of problems, especially in the FI section.
Just research and find out which shops have the most positive feedback and which shop has a lot of knowledge on the VQ platform and tuning. People who skip that part are the bitter ones that have problems with their Z.

6k miles so far and I still have the silly grin on my face everytime I start my car. Haven't had a single problem from day 1 except for a heavier right foot.

Btw Coon, grrrrrreat name! Lol!

Coon-azz

Thanks! Yeah, I married into a true Coonass family from LA.

this is good intel! 6,000 is a good run. I would assume that if you had an issue, it would have reared it head by now. (AND we don't want any issues) .
Also, based on my own experiences, your comment, "Just research and find out which shops have the most positive feedback and which shop has a lot of knowledge on the VQ platform and tuning." seems simple, but its (in my opinion) a major factor in the install. This will be were I focus my efforts next.

Coon-Azz -
My 2013 is now running flawlessly, and it is my DD. My problems related to the fact that mine was the FIRST 2013 to have a Stillen SC installed.
Cost was also higher for install and tuning because of that fact.
Stillen does run sales, especially at the end of the year.
Keep your eyes open, use an experienced installer/tuner (or install yourself) and you may well get away with 6K or a lot less. Some used kits being sold here are an option to consider as well.
Bottom line is, the car is fast enough to be fun without the kit. With this FI kit, it is much more fun. How much is that worth to you? What is your $/fun ratio?

dansracing

Did you upgrade any of the plastic parts from the kit like the idler pully?
