To be fair, Stillen has made no mention of what trim they are using. I feel they can combat this issue by switching trims.

They used a Vortech V3.

That's the supercharger. Vortech offers two trims though for the V-3... Si and SCi. I feel Stillen could work with Vortech to make a custom trim as well.

Did the gains match what was advertised in your case?

They are simulating driving in the Northeast in 30 degree air temps in California where it has been lucky to get down to 50 in the evening? is |

Granted its not track testing in 120 degree weather, but it sure is a little better than simply doing dyno runs. (not a dig at gtm, I dont know what they are doing for testing) Last edited by RCZ; 03-04-2010 at 12:20 PM. |

If they take it out to the "desert" right now they will be running in almost the same temps as Los Angeles. |

how about we nip this in the bud before it becomes yet another pissing contest? I appreciate the testing done with this kit, driven hard at a track will simulate the worst that can be done to the engine REGARDLESS of outside temperatures, if it performs well under heavy stress, the daily driven commute can in no way exert the car to such an extent, so if it holds up under stress, the reliability factor increases 10 fold. Stillen has an EXCELLENT track record of customer service, so how about we all sit back, chill, and wait til both companies finalize things?

I'm sure STILLEN will have a much more thorough update soon.

Trying to get in above all of the noise in here.
Good job to the guys at Stillen. I may not be a proponent of your older kits, but outside of the aesthetics I am holding off on passing judgment on the new one described in this thread. One question, though. Kyle, Josh, anyone at Stillen - What boost level was used to ascertain the power shown on the dynograph posted? Thanks for the candor.

The Eaton MP62 supercharger was designed for engines with a maximum displacement of 3.5 liters. The MP90 is able to flow more air and therefore produces more power than the MP62 but it is substantially taller and requires an even bigger hood bulge. During our testing of the MP62 We found that the most efficient boost level on that kit was around 7 or 8 psi. After that, the supercharger would begin to cavitate and more boost actually became less efficient. If I'm wrong about how much boost you were running please let me know and I will change my post but I do remember seeing somewhere someone said they were running a 10 pound pulley on our kit. [QUOTE=RCZ;428448]quick question Kyle, some of us rev to 8150rpm right now. Not that its a big deal, but I assume the tuning map for the kit is only responsible for 7500rpm? QUOTE] RCZ, I don't know the answer to this question yet. I will need to do more research for you and find out. Quote:
So, we do what we're able to do which is take the car to a closed air base and beat on it for a long time. Then we park it for a few minutes, let everything heat soak, then go straight back out and do it again. As you know, these cars have problems when on the race track being pushed hard for five or ten minutes. You can not possibly and SHOULD NOT simulate those driving conditions on the street or on a dyno, so we have gone to our test facility to simulate them as best we can. By pushing the car hard and really putting it through stress we are able to get a good idea of how the car will perform during the middle of summer at a road course. By the way, here are some pictures of our red 350Z that was purchased by a man in Arizona. The only work that the customer did to the car after purchasing it from us was a roll cage, racing seats, and a door panels. Every other component on the car is a standard off the shelf component and he has not had any issues with overheating when he races at Phoenix International Raceway. |
