My point is that given the pulley and compressor size differences between the Vortech blower and the Rotrex of the two competing kits, the torque curve differential is explanable by the amount of CFM moved at lower RPM ranges by each. Again, no one from Stillen has responded stating that I am incorrect. That said, I am still waiting for Stillen to respond to the PSI levels and why it's so important to keep them from the masses until a "Press Release." This is a bit confusing. I am also waiting for a response on whether or not Vortech has ever released a kit running 10psi or better that was CARB legal. (I already know the answer to this one) |

To be honest, I have absolutely no idea how much boost Vortech has used in some of their previous kits. That would be a question for Vortech. Keep in mind this is not a Vortech kit...This is a Stillen kit utilizing a Vortech compressor. All of the engineering, testing, and development has been done by Stillen. |
No magic number, no sale. Every Stillen S/C should include a magic # in the box!

"Obviously it's above 4 pounds and below 10" (4+10) /2 = 7 psi. Done!

If you can give me a logical reason for waiting for the press release to state PSI after having posted a dyno chart, I will be satiated. Until then, I will probably continue to pose the same question over and over again. :) And I understand this is a Stillen kit. But, you quoted another member here on their reasoning behind why 10psi would not = CARB legal. I see this as you insinuating that this is the reason why 10psi or better was not used to reach the horsepower shown in the posted dyno. I am not comparing your kit to the Vortech kit. I am merely stating that 10psi can pass CARB and I honestly do not buy that your dyno pull posted was done on anything less. It it was less, it was certainly more than 8psi. The reason I am so verbose in my questioning is due to having been promised the world by Stillen salesmen when I researched and purchased one of your SC kits for my now sold Pathfinder. What I was sold and what I received were two completely separate items. Not physically, but in quality and performance. Having been in this game for quite some time, I am looking for complete transparency from vendors. Speaking of tranparency, keep in mind that whatever PSI is posted in the 'Press Release' will have to reproduce 422whp all day long or people will feel duped. |
There are a few reasons why we have not released what PSI that test was at. The primary reason for releasing the dyno without boost numbers to follow was simply to show the capabilities of this kit without even pushing it hard. I assure you, that dyno was performed at less than 10 psi.
The main reason we do not want to release a horsepower figure in relation to a boost level is because the car we were testing on (G37 auto trans. with large 20" show wheels) was less than ideal. We are currently in the process of switching the kit to the manual gearbox 370Z with stock wheels which should be improved due to its more efficient drivetrain. It is very possible that running less boost on our Z will produce the same numbers that we saw on the G and people would say but wait...the horsepower is the same but your boost is lower...So, rather than having any confusion at all, we are switching to the more efficient car and from here on out will stay with the Z. Also, that was a prototype run...Look at the date on the dyno, that was back on the 19th. Since then we've changed our prototype charge pipe and a few other pieces. All we wanted to do was show the early development of the supercharger to show that it has more potential than the VQ35 supercharger did. Again, we were running less than 10 psi, and we are doing all of our tuning on 91 octane pump gas. When we have our finished production kit we will have a finalized dyno showing the horsepower of the kit and of course we will list what psi we are running. Right now, it's too early to confuse everything until the kit is completed. In regards to running 10 psi on other Vortech kits. I don't know why Vortech chooses to run 10 psi. I assume it's because they feel that the engines can handle it pretty safely. Perhaps it's because the compression ratio on the Mustang GT is only 9.8:1 which is significantly lower than the compression ratio of the VQ37 at 11:1 I agree with you completely. The percentage gain between the base test and the final test after installation of a supercharger should be the same as the manufacturer's after taking everything into consideration. To say that the final rear wheel number should be at least identical I can't really agree with because there are a lot of things that need to be considered such as elevation, air temperature, transmission, wheels...But yes, the percentage of horsepower gain between baselines should be relatively similar. |
Understood. But, again, stating what PSI you used on the test G37 to ascertain the dyno posted should not be an issue. I don't see that this will confuse anyone nor do I see that it is relevant to the 370Z kit that is yet to be installed/tuned/tested. (Granted they are the same kit with exceptions being different fuel delivery and possibly the loss of the strut bar.) I honestly would just like to know what PSI is required to achieve 420+ at the wheel with 20" wheels. A lot of people have these on the 370Z, as well.
Also, as a potential repeat client, I would love to see transparency when you post dynos. Witholding key information as to how the quoted power was obtained is not transparent. And don't mistake my meaning - I don't mean that wheel horse power numbers should be identical...but, more of what you stated of the percentages you purport in your advertisements (threads) should be reproducable by most, if not all, who purchase the kit. This wasn't the case for me in my last experience with a Stillen produced SC kit. Even when running 93 octane and not the piss-water you Cali guys call fuel. :) But, I digress. Hopefully we will see some honest and complete posts about the previous testing and any future testing. :cheers: |

lol, guess Stillen should of released nothing. Sounds like they would have been better off.
:eekdance: |

Instead they focus on the information they don't have, think of dubious reasons why they don't have the info. In the end this is information they will have before they can actually buy the product anyways....So why make such a point that you don't have the info today.... I don't get it.... :icon14: Patience is a virtue... |
^ no one gets it. Kyle has a LOT more patience than I do. I would've told him to f off a long time ago.
|
Keep up the good work guys, we're looking forward to the S/C battle, I know a longer wait on our behalf is needed to ensure the quality and reliability of a product.

the problem is tyhat stillen has their sales men on here selling there SC and not the guys that are developing it. So really what do we expect.

Even though he might seem like he's trolling he does make quite some valid points.
What are we 5th graders with low IQs to get "confused". I feel offended lol I still can't find a reason why the boost pressure was omitted honestly, reminds me of the days back in primary school when I gave in my report card with a few grades scribbled out, and it sure wasn't because my old man was going to get confused lol |
lol +1 :icon18::icon18::icon18:

Storm, not trying to pick a fight at all but here is how I see it.

(in an effort to get this thread back on track)
we know Stillen has released all that they are comfortable with before the soon to be press release. So let's get of that subject and focus on the fun. For those who are considering this SC, what is your goal in either HP or track/drag time or something else? And what other mods are you planning to run to make the most of the SC? Are you planning on replacing the clutch? |

lool. i just ordered some from spawn and HP. see if i get it. (derailed again?) |

I'm not a drag expert, but I would think you would need +500 HP and torque at the wheels to get a 370 over the line in 11 seconds |
