Preparation for the STILLEN supercharger

Kyle@STILLEN

Yea, we have found a few sources on mixing 100 and 91 to get a final outcome of 93 but I don't know how much I trust it and I don't really want to risk our customer's engine's on it.

We do have plans for additional upgrades but it's a bit early to talk about them yet. We are a few months away from testing on those systems.

Josh and I are putting together the press release this week. Our graphic artist is putting together a short video, and the engineer's are on the dyno with the Z. As long as everything goes well with the testing we should be releasing all of the info soon.

Mixing higher and lower octane fuels to achieve a middle ground is a long-standing practice and hasn't resulted in any catastrophies that I know of. But, even if there were an inherent risk, you wouldn't be risking customer's cars on it, no? You would be mixing on your own car to produce a 93 octane base map tune for your flash that comes with the kit. Or am I missing something here?

Kyle@STILLEN

You are correct, and we have done that in the past on some vehicle's. For example, I mix 100 octane with 91 octane on my dirtbike all the time.

But, if we are preparing a tune on our car using a 91 mix with 100 octane and say we don't get it 100% right and we end up with say 95 octane fuel...Then we're sending out a tune to our customer's who are in states with 93 octane hoping that the fuel we had in our car was truly 93...when in fact it was 95 and therefore the tune is going to be too aggressive.

is that a better explanation?

Basically...it doesn't matter what fuel is in our car...we can tune for it...but to trust that the fuel that we're using is truly 93 octane and then to send that tune to a customer...THAT's what puts the customer's car in danger.

Another wrench in the works is that California has oxygenated fuel which also sucks...We have really crappy fuel out here.

Yes, and I actually grasped that. But, unless you *really* dropped the ball in your mixing of fuels, that scenario is next to impossible. Looking at it that way, you could have all sorts of scenarios play out for the negative. What if the fuel you received from OK was watered down? What if it had degraded? What about summer fuel vs. winter fuel? (drastic differences in 93 here) All of these things are really sort of moot. If you really wanted to tune for 93, the mixing is easiest route. And I was just throwing it out there to help.

Edit - saw your addition. It's cool. Whatever you guys feel is best for your company. Truly was just trying to help you out. If it is really not an option for you guys, no worries. If you want to know more about it, here is a good fuel company created chart on mixing for different octanes.

I understand completely and I hope you didn't take my reply as argumentative or anything like that. Sometimes I just like to clarify that I explained myself well but by asking if it made sense can sometimes appear rude...I hate the internet for the simple reason that it can not convey any tone in your writing other than "wow, this guy's just being a jerk!" Unless you throw an LOL at the end of everything you write in which case you look like a sixteen year old girl texting her girlfriends.

To be perfectly honest...We don't like to take chances when it comes to some of the really important things like fuel, brakes, tires, roll cages, seat frames...Any time that something can fail in a catastrophic way, we like to take a lot of pre-cautions. For example, you should have seen all of the testing that went into the development of the CCM brakes for the GT-R. We tested out at El Toro air base for a couple of months with those things. We didn't want to put the CCM brakes in the hands of a customer only to find out that something might go wrong. The good thing...we found out that they are a PITA to bed properly. It literally took us two days at ridiculous speeds and temperatures to get them to properly bed in. So now, AP Racing puts them on a brake lathe before we send them out to a customer. We don't ask the customer's to bed them in because we don't think it's safe, or even possible to do it properly.

I hear you on the first paragraph. Tone, enunciation and such are truly lost and a lot of times we all are "read" out of context. No worries. I didn't think you were being a jerk. I just thought you might look at my 'advice' a bit askew due to my past posts.

And I can certainly appreciate your desire to put out the best product available. I, as a consumer, expect that from all vendors. And if I thought, for a second, that there would be any issue with you mixing fuels to make a canned tune I would certainly never recommend such. Still, you should consider it an option. Certainly don't take my word for it being a viable option, but do contact fuel companies and get their take on it. You will be very surprised at what they say you can do.

Kyle@STILLEN

This could be very helpful, I will pass it to my engineering department!

Thank you very much!

You are welcome! And we're typing at the same time and making a mess of the quotes! :LOL'ing like a 16yo:
