Sorry for not answering you sooner. I thought I knew which trim we were using but I just wanted to double check and I was right. We're using the SCi-Trim.

Thanks for the help! I already see tracking number's in the computer system for those Gen. III's you ordered today! Now call Dean back and order some of these blower's! LOL

Working on it, we've got a few people very interested in this kit :stirthepot:

The kit has been developed, at least the one that really is going to be the most important. Just bc a car has a supercharger of the same brand does not mean it will sound the same. Piping, intakes, all are different and were fabricated for this car, which is why it took so long for stillen to make a great product.

The video is just a sales pitch, no offense kyle and its nice, but I want to hear what this thing really sounds like. Gtm put it up and alot of people did not like the sound, but in the past the sound of this should be exactly what I am hoping..

Has anyone thought about using cobb for the tuning?

No offense taken. We are not arguing that the video is a sales pitch in our attempt at showing you guys just some of the testing that we put into this kit.

I'm guessing you want an idling video? I will on getting that for you this week. Steve went to Nevada with the car this weekend and plans on going back out again this week to do some more endurance testing. But, I will do my best to get some video for you.

If someone can answer the last question, I'm assuming you can answer this one. If you did you Cobb, and planned on don't plan on getting a dyno-tune, would it be just as safe or what? I guess my thinking on this is that Stillen worked with UpRev throughout all of this so it just seems like they would know more about tuning there supercharger. I am totally asking as a newb so anything positive would be appreciated.

Also, with the upgrades that I have, If I'm understanding it right: I will pull info from my ecu and send it to Stillen.... Then they create a "safe" tune for it? Someone correct me if I'm wrong here. Thanks

Idle plus some revving :tup:

I talked to chris at cobb and he said the cobb and tune it as well. But no sense in having two AP

If someone wants to use a COBB tuner they will more than likely want to purchase our "tuner kit." This is the kit that comes with everything except injectors and a fuel pump. Then they will need to take that setup to an authorized COBB tuner so that they can have their car re-tuned.

DO NOT INSTALL THE SUPERCHARGER WITHOUT HAVING YOUR TUNING SOLUTION READY!!! I can not stress this enough! You can not just install the supercharger and then download your normal, off the shelf UPrev, or COBB tune. Those tunes are optimized for naturally aspirated vehicle's. Their a/f and timing calibration will destroy your motor in no time...You need to have a tune set up specifically for forced induction.

I will elaborate on the tuning as long as I can...I just need to get permission from the guys at UPrev to make sure anything I might say is not proprietary.

I plan on using uprev tune for awhile then maybe switching to the cobb later down the road if at all. I already had the cobb though.

So am I correct on the method of tuning for the S/C set up then? I send you info from my ecu and you tune it based on that info and my mods and everything to create a "safe" tune?

To start with, the only thing that we will be tuning for is the supercharger and a cat-back exhaust. We won't be tuning for high flow cats or headers right away but it will be pretty soon on the list...especially with some of the exciting projects we have coming in the next couple of months.

You will basically download your tune, email it to us, we will make the necessary modifications, and email it back to you. However, this process will change after we get a database of ECU rom's on file. Once we have a database of tune's done you won't have to do any emailing back and forth or anything like that. Just a simple plug in, download, and drive.

so we will get an access port deal with the kit? you have any pics of that?

Kyle idling and revving would be perfect, would love to hear how the car is running? I bet pretty smooth will all the last little bits done, thats gotta be a sigh of relief that all your hard work and time is running nice and smooth. Their is nothing like a clean install man, just turning on a car and going with a new part lol, what a feeling!

not sure you understand what a sleeper is? its a car that was never intended for performance :P ie a civic, or a suv, or old truck that has a 7.2 super duty in it whats a twin screw S/C lol. a 370 never can be a sleeper ;)

I think what he means is that he wants to keep his Z looking as close to bone stock as possible, so when people see him on the street they think, "Oh thats just a stock Z," then they get suprised.

My theory just keep it looking stock, unless your at a meet and you have to open the hood, no one on the street will know that your car is modded. Except for maybe exhaust.

Kyle, I know you mentioned that the CARB kit tune would not be modifiable by law. You also mentioned that the first maps coming from you for the S/C are not optimized for HFC's. So I just need to clarify; will the Race kit tune be modifiable? I'm expecting the answer to be yes, but I just want to make sure I don't need to go with the tuner kit instead.

I'm confused now. Sorry if I missed it, but what is Stillen's solution for the calibration? They have one done that they flash into your ECU?

Its UpRev

And just what does that mean??

They are a tuning company: UpRev - Engine Management

Yeah, I got that. So what's the calibration solution?


You're not saying Stillen expects you to go to this place and have them calibrate your car for you, are you?

No, Stillen will ship with the SC the ability to flash your ECU with a standard ROM. The saying plug-n-play comes into effect here, basically designed so after the parts are installed you upload the tune and are ready to go.

Got it. So how do you upload it?

they didn't state which uprev unit yet though

All tuning is usually uploaded through the OBD port.

Probably Osiris....all you do is get the map over e-mail and then upload it to the car through the OBD port from a laptop. 10-15 mins later you're ready to roll with your SC tune.

What I'm asking is... does it come with a tuning device to upload it? Are you supposed to buy one from uprev? Supposed to send your ecu to uprev? What?

stillen will be sending out the cords for the obd port which connects car to usb and then email us the software/ license so we can start data logging

Not data logging, actually just confirming we have your ECU's calibration in our system, if not, the software will copy off the ECU ROM, and you can email to us, so we can ensure the calibration is ready to go as we're shipping the supercharger, and can email you the appropriate tune.

Just ensures you're not left waiting with the supercharger installed if your ECU calibration is one that hasn't been seen before.

if i have an ecu rom that i get off my car via cobb and i still send that to you?

We just sponsored the forum, but I must say WOW, you guys did a great job on that kit. We are going to be building a roadster, and we may have to talk as it will be our show/track car(we know we know, its a roadster and not the best for track, but definately will be fun on the track).

Have any pics of inside the intake manifold with the intercooler in? Just curious what it looks like.

I remember taking pictures like this but I don't think they came out very good...Let me see if I can find them.

Will this fit with a Nismo 370Z? The front fascia is different and there are different cross braces in the engine compartment.

We have not tested on the Nismo yet but we definitely intend to.

so...I'm still a bit confused with this tuning thing. The tuning is only for SC and CBE...does having HFC's screw this up or is this just ignored and doesn't effect the tune as it comes from stillen/uprev?

We do plan on tuning for HFC's but right now we are recommending not to install the HFC's with the supercharger. There will be a tune for it though.

Cat back exhaust isn't going to change the tune much, if at all.

hi kyle - can you please give me more information and show me what the heat exchanger/inter cooler radiator of the stillen kit looks like and how it looks installed if possible? thank you.
