The Truth About Natural Power - A Look At What Makes Power and How Much

Quote from Kyle D

The guy changed his mind and is now getting a turbo kit. I'll sell you the intake, head/muffler package, and tune for $1000. I'll even send you a tuned PCM so you have no down time. There will be a $250 refundable core charge that you will get back once I get your old PCM back. So up front would be $1250 with $250 of that being returned to you once I get your core back. That would give you a full ZZP system for only $100 more than you were originally planning on spending for just the exhaust package and tune. And then you can sell the CAI you have to recoup even more. Food for thought. Let me know if you're interested.

Now that is a deal and customer service. You had better get it while it is there

If Doc&Ruby decides not to go this route, this offer will be open to anyone just FYI but he has first crack at it.

I already have all of it ,Plus some.

Okay Kyle, I'm gonna have to book a couple extra gigs this summer to pay for this! I do astronomy shows over the summer to support my hobbies - looks like every dime is gonna go to the Slingshot this year! I'll probably have enough by mid-July, and that's if I'm really good and don't spend anything on other stuff!

Just one question, if I already have the stock cold air intake, will yours do anything different performance or sound wise from the stock equipment?

You should go for it Doc&Ruby ! I’ll help you with the install. I gave away my SLR intake.

You're the best, dangerdarrell !

I'm going to order the header and exhaust, just have to save a little bit more... can't take money out of regular cash flow, my wife wouldn't stand for it!

I'd love to do the package, but the tune will have to wait a bit - I'm working some extra jobs over the summer for that.

Don't think I'm going to replace the stock CAI, don't think it would make a significant difference. I will replace the filter with a K&N, that should get me 99% there.

I'll let you know when I order the parts - I'd like to do the installation in early June - the Captain will be out of town for a week!

Kyle D I am ready to buy whenever you are ready to ship, PM the details on how to proceed.

Maybe clarifying the below two questions/points will help a lot of people out in this thread. It would be a bummer to see so much wasted effort on education if these certain details aren't addressed...

Why should you dyno a vehicle in the 1-1 gear, and what happens to dyno power readings when you vary from this?

What is the difference between Open Loop and Closed Loop tuning and how does the vehicles O2 sensor work to build fuel tables, timing, etc., etc.?

The 1:1 gear idea comes from minimizing power loss through the transmission, that is all. This theoretically would give you the highest numbers, although there are other factors involved. In the cobalt world, I do not see much difference between 3rd and 4th gear pulls, aside from the intake temps climbing a little more in 4th (more time in boost, more heat in the intercooler). Sometimes you simply CAN'T use the 1:1 gear, due to traction or top end MPH. All dynos have a speed limit somewhere.

Almost all stock style automotive ECUs only use closed loop for low load driving, when the ECU is commanding stoich (14.7afr on gas, 1.0 lambda). The common narrowband O2 sensor can only tell if you're above or below stoich, but not the actual lambda reading. This is where fuel trims come in. Basically the ECU says "hey we're over stoich, better add a few % fuel. Ok now we're under stoich, better pull a few %" and the cycle continues.

WOT fueling is almost ALWAYS open loop, aside from a select few oem PCMs and most aftermarket standalone stuff. It's all pre-programmed numbers determining how much fuel is injected and when. This just means that you don't have any live feedack from the ECU, so you have to monitor the exhaust with a wideband O2 sensor and then make adjustments to the pre-programmed numbers after the pull is done.
You CAN force the ECU to run open loop all of the time while tuning, and use your wideband feedback for adjusting the idle/cruise fueling, and this is a pretty common thing. However, for me personally, it is a lot more efficient to leave closed loop active when tuning. Once you learn an ECU/software combo, it's pretty easy to blend your open and closed loop adjustments together.

I personally think the comparisons would make a lot more sense, if you were to dyno Slingshots in 4th gear (1-1) like everyone else does. This would help validate power increases in the same relationship of others that have reported findings earlier.

I don't agree with some of the ecm/tuning statements, but this is your thread. Very curious to see how your NA tunes perform.

Kyle D I must say... Being in Business Development and Sales my entire life, Your words, comments, and the way you handled each questions/response gave me enough insight to fully trust your guidance and opinions.

I just recently purchased my 2nd slingshot and while the 1st was NA, I planned on going boosted with this one.

You just got my business and want to discuss the process of getting your turbo set up.

What is the best way to contact you for further details on going boosted?

Are you going to make it Huntsville? Kyle will be there.

Hope you can, it would be nice to finally meet up.

Unfortunately I won't be able to make it... I am in the middle of peak season for my industry and will be unable to get away during these next 5 hectic months to truly enjoy a getaway.

1 day though... I will schedule a vacation for an event and be able to FINALLY put REAL faces to names. Looking forward to sharing some drinks (and apple juice for the non drinkers) and cigars with some of you.

Pretty sure there is an event in the fall usually in the Ozarks. Least someone mentioned there was last year.

Mateo the best way to get a hold of me is to email me directly at Kyle@zzperformance.com I'm in and out of the office constantly so email is best which also allows me to respond while on the go and after regular business hours. LET'S GET YOUR SLING BOOSTED!!!

I will shoot you an email after work today and let's talk!

Mateo;

Just let me say you won't be disappointed in the experience that ZZPERFORMANCE provides, Kyle is a great person to deal with and always goes above and beyond with a true passion for the slingshot, as far as their product it will speak for itself, it is very well engineered and does exactly what they say it will.

On another note what is the chances of getting a group buy on a stock pile of rear tires for our slingshots?
