A few thoughts on power delivery with the S/C: The stock vq37 starts coming in to it's power band between 2,500 and 3,000 rpm, Then holds a flat torque curve

A few thoughts on power delivery with the S/C:
The stock vq37 starts coming in to it's power band between 2,500 and 3,000 rpm, Then holds a flat torque curve from 3,000-6,000 rpm before it starts falling off. The VQ37 with the Stillen S/C acts like stock from 2,500-3,000, where the torque is rapidly increasing, but then continues that linear increase in torque all the way to 4,000 rpm before then engine is fully "on". Then the torque curve is flat from 4,000-7,000 rpm before it starts to fall off. Overall, it's a very useable power band, being near peak torque for a 3,000 rpm range. The fat part is now a thousand rpm higher than N/A, but it's still making more power than the N/A engine everyhwere in the rev range. Compared to a larger displacement N/A engine, the downside is lower torque from 3-4k rpm, but that's only if the N/A engine has variable valve timing. Otherwise, the larger N/A engine will suffer the same problem. Compared to a turbo engine, the downside is lower torque until the turbo spools up, which would occur, when... 500-700 rpm earlier than the supercharger? |

So the automatic loses 30 to 40 WHP, that's not bad. 400WHP daily driver kicks ***, that torque level should be easier on the auto trans. 2009 infiniti Q56 5AT is rated at 395 ft/lbs torque at the crank, I know the transmissions are not identical but they are both RE5R05A. I hope my trans will hold up well, I think the shift kit will help alot.

Just an FYI.. Over the past month we have shipped out many superchargers and have received great feedback from our customers on everything from the kit itself, the ease of installation, the quality of the components and the driving experience. However, we have also found there are variations in boost with some cars experiencing pressures higher than we are comfortable with.
As the reliability and longevity of our customers’ vehicles are our utmost concern, we are contacting all those that have been shipped the supercharger kit. These variances could be caused by differences in exhaust components, climate, elevation, etc. and we want to ensure their setup is within the proper boost levels. If any STILLEN Supercharger customers haven't gotten their communication, please contact us at 866-250-5542 or feel free to send me a PM. |

I got an email about this, and it said something about being supplied a conservative tune to replace the existing tune. Where abouts would i be receiving this tune? How would i go upon replacing this tune with the current one?

Josh@STILLEN,
I am starting to doubt how easy the SC is to install because my "Dealership sucks at life" When they first looked at it they were saying 35 hours. I posted on here and people helped me find how many hours it takes for a normal person so they dropped the price for install $2,000. From that point on I should of taken my car and ran but since I the closest shop that could do it is 2 hours away and my wife would not have a way home we opted for the closer shop. Now the reason for posting. The shop is having trouble with the install. They don't think the stillen oil cooler kit was built to work with the SC. Is this true or not? The shop tried to call but you were closed for the 5th. Also since the car is still there they are waiting on the new tune before they release the car. Do you know how long it will take or is it as easy as downloading a new tune from the net? With the new tune are we going to be seeing a big difference in DYNO numbers? If you are going safer then you would expect to lose some HP. Thanks |
