So i was driving my Z with the new Stillen SC i put on it for about 2 months. It ran like a champ. Then Sunday I was running numerous errands and at a stop light it decided it didnt want to take off anymore. It would drive but as soon as i would give it gas it would just lag out and sputter with a kind of backfire sound. I made it to a parking lot where i let it cool. It was about 92 out that day and i had been driving it hard for like 2 hours. I drove it home but at very low rpm's. When i kicked it down it would lag and sputter. I let it sit overnight and now it runs perfectly fine again. Any suggestions?????
P.S. The temp guage remained in the middle like it had all day.

Well there arent any leaks and all hose clamps are good and just had fluids changed when i put the SC on. So are you saying you cant drive a Z with a supercharger for more than an hour on a hot day? It wasnt like i was racing. Just having some fun in the streets.

DJamps...I got it in my garage and called the installer over. He hooked up the computer and it didnt give any codes at all. He inspected everything and it was all good to go. I drove it to work this morning and its running perfect again without any noises or hiccups. Just trying to figure out what would have caused this. The temp guage was in normal range.

Yeah Djamps. I appreciate the input. I am going to look into that further. Especially since now when i drove it at lunch and got on it, to see how it acted, it stutters at quick acceleration. Damn!! Hope i can pinpoint this issue.

What year z ? Is the old stilled kit or the new one with vortech blower ?
Previous post about cats is plausible for sure. If your running stock exhaust the cats could be over heating enough to crack if your egt's are getting high. When the guts crack and come out the can clog if no where to go.
Also you could have had a injector hanging or malfunctioning. If its the older stilled you have that added injector right ? If a car is tuned based on additional fuel being added you could have leaned out if it was not working properly.
Do you have a egt or a/f gauge ?

gsxr,
Its an 06 and yes it is the older stillen with the 7th injector. However, Im running Greddy EVO 2 exhausts which are huge! So im definitally not inhibiting exhaust. I actually was told that im not creating enough backpressure with those for the SC to work at its maximum. The only added guage is a psi guage and an extra oil pressure. No air to fuel or egt.

Get an A/F for sure asap... Especially if your leaning out, you will want to know... Any time there is a leniency in boost, thats where big problems like "BOOM!" can happen.
Quick thought, if you have Cats still, and your cats are the issue, you should be able to see the effects on any OBDII computer for the pre and post cat bank sensors. Just one other thought to prevent having to possibly pull the cats un-necessarily.

So if its heat related. What if you lived in Southern texas or arizona where it gets 110+ frequently and you were stuck in traffic on the interstate. Would you fry your cats repeatedly? Im not trying to be a smart-*** on this whatsover. Just trying to figure out the heat affect on SC'd cars.
