You only lose money on a slingshot is if you SELL it. So to save you from losing any money on it, just order a new one and when it comes in, you can GIVE me your old one. See? No sale, means it's only a loss on paper
Brilliant!

hey Dave... going to install your coil cover tomorrow. it says "begin by removing the plastic retainer located on the passenger side front of the stock valve cover." I don't see what that is referring to on my 2017 slingshot....... ???? Thanks
That is for when installing on the Solstice / Sky 2.4L, not a factor on the Slingshot.

So that I don't plagiarize, let me send you direct to the DDM Works ReRoute Hose information. Great pics and explanation. I don't think it's "required" but it helps clean up the hoses too. Dave@DDMWorks can give a lot more details I'm sure.
The coolant re-route helps the steam that builds up in all engines around the cylinders get out of the system easier and get back to the coolant tank where it can condense back into coolant and go back into the system. It is a great idea on turbo/supercharger engines since you are generating more heat in the system, even on naturally aspirated engines it is a good idea.
Hope that helps,
Dave

Display MoreI’m done with the install of the DDM Rotrex supercharger kit and I now have 200+ miles on it so I feel like I can write up a review.
I ordered this kit during the Black Friday deal last fall, took about 5 weeks to receive it which I thought was good given holidays. Then it sat in my basement to wait out the long cold MN winter. Occasionally (really multiple times per day, my wife will attest to that) I would go down there and check on it, go through parts again, make sure it’s all still there, just waiting for warmer weather.I gave in the first week of Feb and bought a garage heater....yay!!! Time for the install!
the install took me several weeks of a couple hours here and there...doing a step or two each time I had a chance to work on it. I have twin toddlers and my wife is a tax accountant so I was working, being full time dad and trying to squeeze this in at the same time. The girls did help with tie wrapping some of the wires
. If I worked on it solid, I’d imagine a day and a half would be very doable for me. Only help I had was to remove the hood.
The instructions were really clear, I did contact Dave@DDMWorks a few times via text and once over the phone to clarify a few things, every time getting a quick response that answered all my questions. The kit is really well made, designed and the fitment of all parts was great. I am probably average mechanical skills, maybe below average, and I was able to do it pretty easily. Just took my time. I did have to buy a few tools like a larger socket for the crank bolt, some shears to cut away the rear radiator shroud, grabbed tool and endoscope to retrieve a lost bolt in the bell housing (stupid mistake!) and modified an Allen key to get one of the bolts in that attaches the supercharger support to the front of the engine. I did not remove the radiator, would have been easier if I did that.Finally got it all together, worked up the courage to fire it up and took it for a first drive...it ran flawlessly!! It was really hard to keep the RPMs down for the first 65 miles of break in, which I finished the break in the next day. Once broke in I could let it rip...and this thing is wicked fast! Massive improvement over stock. I have had one quick car in my life (1995 Eclipse GS-T) but nothing like this, this is really my first true performance vehicle and it is so damn fun! I loved my slingshot since I test drove it back in fall 2016 and I love it even more now. The power is so smooth and pulls like a freight train. The blow off valve is addicting. I have the welter 2.5in exhaust as well and it sounds awesome across the entire RPM range. I smile and giggle like a kid every time I press the red button....heck I do it when I see it in the garage every morning!
For anyone else thinking about adding a supercharger, you should do it! If you do, go with DDM, they make great products and stand behind them. I also have the DDM surge tank, fuel rail, sway bar, mounts and end links...maybe more I’m not remembering, they are all great products.
Here are a few photos. I’m done with all the mods I want too do now...said no slingshot owner ever...time for wheel and tire upgrades!!
Install looks great, thanks for the review!

Thanks Dave I noticed that the steering wheel was not centered while driving on that 2019. Alignment?
I think it is just the camera angle doing something weird, both steering wheels were pretty centered during the testing. We have done an alignment on the 2020, but it was after this video was shot and because we installed the new 4 way coilovers and lowered the Slingshot, which required a little tweak to the front toe.

Display MoreWell, thanks to being sheltered in, I finally had time to install my electrical work to handle accessories, lights, dimmers, etc. Here's an overview of the work:
Fuse Box and relay bank and bracket:
Terminal Power Distribution Strip:
All the wires of the relays and connections for the fuse box go to the distribution terminal strip. So this allows total flexibility of connections should i need to change things as time goes on.
I installed two more switches on the dash under the radio (my radio is aftermarket). One is for driving lights. But while I was at it, when the driving light switch is turned on, it sends a signal to the radio to dim the display, and I did not like how bright the start switch was illuminated when driving at night, so it also dims the switch to a low glowing red. Sweet.
Also, I found a great voltmeter on Amazon for $11.87. It has a large readout, and I was able to mount it on the firewall to the left of the instrument cluster. The blue digits are the same color as the instrument cluster so it looks like something the factory might do IMHO.
If you've read this far, you may be interested in the schematic for this stuff. It is below:
We can only hope that all the Slingshots that come in for installs have that nice of job done on the wiring, good job!

With our new 2020 Slingshot showing up and having some time with it now, we wanted to answer a lot of people that keep asking which one is faster. We recorded some video and put together the following to show which one is quicker stock from Polaris -

We used the Rust-Oleum Epoxyshield on the shop side of our building about 6 years ago now, it has held up extremely well considering what we have put it through. I am actually going to use it at the house also in the next month or so.
2 things that I would definitely recommend though - the prep definitely makes a big difference on how well it sticks. We used a surface grinder thing (not sure the technical name anymore) that roughed up the surface a little bit, rented it through Home Depot also. We also did the Acid etch and cleaned the surface very well before applying the coating.
The other thing I wish we would have done is applied the clear gloss finish. It was not part of our kit, but a friend that applied the same kit with the gloss coat after looks amazing.
Hope that helps,
Dave

LOL, I need to find some cheap 18" or bigger wheels for the back then, I'll start looking around
Dave@DDMWorks so, how high can I raise the front with your coilovers?
We have tested a 1" raise with the coilovers before, if you want to get really crazy, we can get you longer shocks for the front, just let me know how high you want to go
-
Slopoke said I should put some big knobby tires on the back of my quad and take it sand duneing. I wonder how high I can raise the front end with the DDM adjustables?
I want to see one raised up!
-
Dave@DDMWorks nice packaging and thanks for the souvenirs!
I would love to take credit for that, but that is all Angie@DDMWorks and the rest of the shipping team in the back. Glad this all worked out for everyone and hope you enjoy it!

Severe thunderstorm and tornado warnings in about 15 minutes
Looks like you are getting what came through here around 3-4 this morning. Pretty serious storms, a Tornado popped up here in the upstate, lots of branches down, etc. Stay safe down there!
-
So got my new coil pack cover in to go with the valve cover as my old one covered too much of the flames. Not only did this one fit better I figured it only appropriate to use the ddmworks brand as Dave@DDMWorks was the one to get me an extra valve cover to complete this project without taking the sling down.
Those flames look fantastic! Thanks for the order and glad we could help you out
-
So Dave, how does that compare with the previous 2015-2019 version from a couple years ago?
We did some more testing today on a 2019 Grand Touring that we are installing a supercharger kit on. the 1/4 mile took 15.2 seconds @92.5mph and the 0-60mph took 6.6 seconds. Temperature was 3 degrees warmer, otherwise same road, same tires, same driver

Display MoreHappy Birthday SlingshotInfo dot com!
4 Years out of the dark!
Thank You rabtech ! and Allison for your continued support!
Dropped a little something for the forum under the "Donate" button...
You have my vote for FOUR MORE!
mmmm, cupcakes
Great pic!
Happy Birthday to the Forum!!

Once you compress the spring, the upper mount will slide down and then off the shaft. The only thing holding the upper spring mount in place once the spring is compressed is the bump stop. You may need to slide the bump stop down slightly on the shaft to have enough room for the upper mount to slide out. You will see that the upper mount has a slot in it wide enough to fit over the shaft of the shock. The lower mount is not easily removable.
Hope the helps,
Dave

I think that with an automatic these times are probably a fairly realistic example of what most drivers could expect - just find a nice straight level stretch or road and mash the gas to the floor and let the vehicle do the rest. things should be pretty close to the same every time.
On the other hand doing this with an earlier year slingshot without the automatic and now you are putting things much more in the lap of the driver and his/her ability to not only get the best out of the machine, but also to do it consistently
as a side note do these new slingshots with the auto have launch control?
The times with the Autodrive were very consistent, I did a total of 9, 1/4 mile runs and the times were 15.75-15.86 and every speed was 90mph.
No launch control on the auto's or manual 2020's that I am aware of.
I did learn that if you apply the brake and the accelerator at the same time the ECM will throw a P150A code -

Numbers from Polaris for a 2018 SS show:
0 to 60 time of 5.5 seconds (video showed 6.9 on the 2020)
1/4 mile - 14.6 sec and 96 mph (video showed 15.8 and 90 on the 2020)
Not sure if we should be questioning how Polaris came up with those numbers as the HP is almost identical. Is it the Automatic or rear end ratio?
The shifting of the autodrive is definitely a little on the slower side and is hurting the times for sure, I would think the manual version of the 2020 would be about a second quicker from just the shifts alone. Not sure the testing conditions that Polaris had when they did those times. We have been testing on sunny 75 degree days on definitely not the greatest pavement around for traction.
We have another install this week and if the temperature is about the same I will try to get some baseline numbers at the same place with a 2.4L Ecotec manual to see the difference.

So Dave, how does that compare with the previous 2015-2019 version from a couple years ago?
We have installs every week in April and hopefully we can get one of those turbo/supercharger installs out when it is still stock and get some base numbers to compare, if the weather holds we will do our best to get them.
Also, someone asked me on Facebook how we get the numbers, we use a SOLO DL, it uses GPS to record 0-60, 1/8 mile and 1/4 mile time and speed. We also use it on the racetrack to record laps/speeds and race lines, neat little tool - https://www.aim-sportline.com/…production/solo/index.htm

We have had our 2020 for just over a week now and with almost 800 miles on it now we have learned a lot about it. We went out and did some testing on it before we made any changes to see how it performed straight out of the box from Polaris, here is the video -
