STILLEN 370Z Supercharger System - Announcement!!!

Kastley85891 · 10-12-2010, 05:36 AM

All the extra pulls with a not so great tune, trial vehhicle owners who have already paid, man I feel for the poor VQ under the hood, who knows how long that will actually last even if you have a 'good' tune when the deem it acceptable and release your vehicle back to you.
Damage could have already been done during all this tweaking/ experimentation, sure it could last a good bit but, knock, high EGT, bad ignition timing and boost oscillation can cause all manner of hidden gremlins.

To me my Z would not feel the same.

Interesting point. Never thought of that.

Scary item this morning: 1.0 g corner, fuel starvation with 6 dots left on fuel gauge, transitioning to full throttle at
6k rpm. Heard 1 or 2 detonations then engine immediately went to some sort of limp mode where it would cut every other ignition pulse above 3,500 rpm. Normally it just shuts off. It kept running, but making hardly any power. Oil temp was 180. Pulled over, restarted engine, now it runs fine again.

This is messed up. Fuel starvation with only 103 miles on a full tank? Come on Nissan, what were you thinking, this was going to be a straight line car?

I posted this in the Stillen thread because I'm running their supercharger with the small pulley. Lots of boost + lean a/f ratio = detonation. It wasn't much detonation, but still scary when you have no warranty.

wow, that sounds scary! SO It only does that when you're low on fuel? I still have some low end detonation on my car.

I heard that even stock 370zs will show some detonation once in a while, but I know that is not entirely relavent in your case!

I heard about that too lol, but my car has no ping before the SC. That was something I notice the very first time I drove it. I'm wondering would a lightweight flywheel will help out?

Low on fuel as in low in the tank or low in fuel as in AFR, he mentioned he had a mostly full tank when it happened but yes it is caused by a lean mixture.

I'm sure you get this a lot, but you look like Chappelle.

LOL, yeah. The pic is that mod day @ Mike's.

Man this S/C has turned into such a disappointment. From the day this was announced I was excited with the idea of having a well designed supercharger kit with close to 500hp. But after hearing/reading about the problems people are having, it's really pushed me toward the GTM twin-turbo kit which alot of 370z owners seem happy with.

And the plot thickens. For a moment there, it looked as if things were coming around. I need to just lurk in the background and continue to save my pennies.

Stormcrow: I wish I would have gone for a ride in your car. Perhaps I would have been inspired to make a move similar to what you suggested to me that day at Mike's.
