Preparation for the STILLEN supercharger

Kyle@STILLEN

I don't have an exact answer for that yet but it has definitely been a topic around here.

Our biggest issue is that there is nowhere for us to get 93 octane fuel. We were talking yesterday about possible locations and the closest place we can think of is Oklahoma...We're currently looking into it though.

I forgot to add this in my last post.

This chart shows some different forced induction systems on the VQ35 engines. You can see how the STILLEN roots blower was the best down low, but at high RPM was lacking.

Definitely good to see how the entire hp curves compare and not just the peak numbers. It'll be very useful to compare the final dynos from the two kits when they are eventually available. Thanks for the info.

Cool, are there any plans for a Stillen branded meth/water injection kit? Maybe you guys could talk to Aquamist, SMC, Coolingmist or Snow Performance for some support. I think it might be nice insurance and a little extra power for those who are planning on pushing the limits a tad.

Ah... the horsepower addiction is strong in this one...

Alrighty...early March is winding down. On what day will you be dropping the Press Release? Seems like a fair question

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.
