    I went over there just now and Replied to Stickerdick's thread - Wannagofast Florida 1/2 mile challenge Races | Polaris Slingshot Forum. Here's what I posted - "If anyone is interested in @RABTECH, I suggest Googling him as he no longer posts here." A Google search should lead to this great site! I wonder if my post gets edited or deleted. Of course, I don't know how many people will see the post and want to search for him, but any search should lead the searcher here! :D

  • Questions After First Start of my Hahn Stage 2 Turbo Kit

    IIRC, the factory O2 sensor is wideband (Correction - WRONG - See Bill Hahn's post below. I made a poor ASSumption since both O2 sensors looked pretty much the same. My apologies). Here's a link to a short explanation of the differences between narrow and wideband O2 sensors - Why is a wideband o2 sensor better for tuning AFR than a narrowband o2 sensor? Isn't my 1/2/3/4/5 wire stock o2 sensor good enough? - DIYAutoTune.com

    @BKL the numbers you are mentioning are the same numbers I see on my AFR. The only concern I have its at the higher end when you are boosting, that's when you should see the 12-13 AFR . The numbers go higher on deceleration because your foot is off the gas and the throttle closes. At idle after mine is warm I see the 14-16 range. I have been driving like this for over 10,000 miles. I believe you are defiently fine, you just need to watch the boosted numbers. Boosted you should keep seeing the 12-13s you see higher numbers that is when you should worry.

    Thanks for the feedback. Never having driven a boosted motor before, I had no idea what AFRs should be other than having read that AFR numbers around 12-13 as being most desirable and that I should worry if I see lean numbers, but that info had little detail to it. Having only driven it about 5 miles so far, with only about 1/2 mile under boost towards the end of the ride, I'm still getting accustomed and learning what it does. I hope to get the body panels & hood back on in the next couple days and then I'll take her out again.

    @BKL:


    Can you please describe the precise conditions under which you are perceiving a lean fuel mixture? There is an art to understanding AFR readings, as the optimal numbers vary based on RPM and load.


    Tell me RPM, load, and engine temp, as well as the reading you're seeing.

    Bill, I started a Build thread that lists links to the various threads I'v posted about things I've done to my Slingshot - BKL's Build
    The following is copied from my Build thread and summarizes my initial test ride -
    Today (Jan 25, 2018), I finished getting all of my tools cleaned up and got all of the accumulated trash from the turbo install cleaned out of my carport and the Slingshot, so I finally took my Slingshot for its turbo break-in ride. I only rode for just over 5 miles and thought I'd post some of my impressions. AFR seemed to stay around 15.5-16 at idle, dropping down to the 13-14 range or lower during acceleration. I like to use the transmission to slow down, but I noticed the AFR crept up to the 19 or higher range if I used the trans to slow down, so may need to rethink this driving style. After about 4 miles of sedate (non-boosted driving), I finally gave it enough gas to feel the turbo kick-in and heard the hiss of the system when I took my foot off the gas! Woo Hoo! I didn't want to work it too hard until I had a chance to post here and maybe try to get some video of the numbers during a ride. I need to figure out how to hold my camera/phone focused on the gauge during a ride to capture the video to post here. I'll try to add some ore pics of various things later.


    I'm still thinking about how to hold my phone steady on the meter since I don't have anyone who want to ride with me at the moment (Wife is in her 3rd week of bronchitis and is sensitive to exhaust fumes, anyway).

    That is the AFR gauge that I ended up with. It seems to be working good for now.


    @BKL There is one more place to look for your bolt. If you stand straddle of the right front A arm and take your left hand and reach around the back of the motor where the thermostat housing is there is a little hole/pocket just big enough for a bolt to hide in when you drop it trying to mount a new windscreen. Don't ask me how I know, and don't ask my wife how many bad words I said over and over again when I thought I was going to have to start re-dissembling our sling to get said bolt out of the bell housing! LOL

    I'll take a look.

  • BKL's Build

    I feel a little stupid starting my Build Thread with this question, but where is the Instructional post? The member builds page specifically states - "Please read the instructional post if you want to start a build."


    In late 2015, I added a TD Top (Gen2) and a MadStad 13" Adjustable Windshield (both were Black Friday sale items).


    In early 2016, I added a DDM Works Short Shifter and Bilstein One-Way Adjustable Shocks.


    In mid 2016, I had my 2015 Base Slingshot repainted Yellow by a young man here in Houston. He was very enthusiastic about painting it and only wanted $800. Other bids I'd gotten were between $1200 - 2000+, so I should have remembered the old adage, you get what you pay for! The main thing I wanted was a Yellow Slingshot and I got that, along with some paint imperfections. I'd rate the overall job as a 3-5, meaning as long as you're more than 3-5 ft from the Slingshot, it looks pretty good. but closer than 3-5 ft and the flaws are visible. The painter was thrilled with the opportunity and his effort, even if I wasn't as impressed, but it did meet my budgetary goals as far as cost and my Slingshot is now Yellow! I did the panel removal and re-installation and he did the sanding and painting/buffing. Thanks to @Painter for his panel disassembly tips.


    After DIY'ing insulation and a panel to seal off the Infotainment cubby area from engine heat (Insulating the Infotainment Cubby Area From Engine Compartment Heat), I've gone thru several rounds of stereo installs and currently use a Planet Audio PGR35B weatherproof radio with Bluetooth & USB/MP3 playback hooked up to a Clarion XC2410 amp driving two front 4" speakers mounted above the dash & glovebox and two RF 6.5" speakers in SSV Works Rear Deck (Roll Hoop) pods. The XC2410 amp finally gave me enough power to hear music at speed (of course, having the 6.5" speakers just a few inches behind my ears helped)! :D


    After ordering a Hahn "Slightly Warm" Stage 2/2X system with free StreetRace exhaust in Fall 2016 and waiting for the swing-arm and other recalls to be performed, along with some other delaying factors on my side, I finally started my turbo install around the end of June 2017. I also ordered an Innovate SCG-1 AFR/Boost gauge/Controller, not knowing at the time that the Boost Controller feature doesn't work very well with the Slingshot's reflashed ECU, so I eventually just installed the SCG-1 as a combined AFR/Boost gauge.
    Here's a list of the threads I posted while doing the turbo install -
    Oil Pickup Tube question
    Oil Pan & RTV questions
    Hahn Turbo install questions
    Difficulties Clocking my Hahn Turbo
    Turbo intake clearance of water pump bolt
    Pressure Lubers & a question about oil pressure when starting engine after several months of non-use - I started thinking about making sure the engine was properly lubricated around this time, after my Daughter had to pull the oil pan on her 2007 Hyundai Accent to fix an oil leak. The day after she replaced the oil pan, her oil pump gave up the ghost and the engine needed replacing. The mechanic said he didn't think it was anything she did as the engine had run for several hours before the oil pump died. However, this incident made me paranoid about how long I had had the oil pan off, so I researched lubing newly built motors as I wanted to make sure I had everything properly lubed before I started the motor after the turbo install.

    I strongly support the concept of Net Neutrality. I already pay my ISP (COMCAST) a premium for a faster connection and don't feel an ISP should be allowed to slow down access if I choose to visit a site that hasn't yielded to an ISP's blackmail demands to pay for faster content delivery.

  • Another Battery Question

    Quote from edwardaneal

    What you say is correct and I am very familiar with both Ohms law and Watt's law...
    ... if the charts called for a #4 wire in my Slingshot I would most likely run #2 and if it called for #12 for a 20 AMP circuit I would use #10

    That's always the safest thing to do. As it states at the bottom of the TESSCO chart I linked earlier - "For safety and best resultsWhen (sic) circuit is longer than 10 feet, always use the next larger gauge size".

  • Another Battery Question

    It bugs me when I come across multiple charts that seem to contradict each other. I realize that different assumptions for safety factors can impact the choice of wire for a given application, but I'd still expect the choices to be within a gauge or so. I've used the TESSCO chart for years as it seemed to have relatively similar ratings to other charts I'd compared it to. Just goes to show that just because you found it on the Internet, ... :D

    Those lizards may still revive according to news reports I saw. Somebody was joking about some guy collecting supposedly "dead" lizards in his car that then warmed up and caused him to crash when they started moving around inside his vehicle.
