Hey everyone!
Follow us on instagram as we run thru the prodigy turbo install in real time.
We are about 2 hours in right now.
I wish I could be there. I'd like to see how they accomplish things compared to how I did them. How many things did I do wrong, or just the dumb/hard way? How many cool little bits of info about the kit are being discussed?
Well? Have you driven it yet? Initial driving impressions?
Wow intercooler . Any updates of availability. Thanks ross for the posts
Yea I drove the hell out of it.
Its an impressive until. Full article coming.

Do you have an ETA on dyno results? Can't wait to see the torque curves on the same chart with the superchargers.
You guys should post the instagram photos here.
it was cool that you instagramed the whole install. I was watching to see if you got hung up anywhere.
Ok, So the install went pretty much off without a hitch.
The plan was for us, JL guys, who had never seen a turbo before, install it with the Prodigy guys watching for issues as we went. Our ace, Carolina Pete lead the charge, as usual. Like any true mechanic, it was hard for Wes from Prodigy to watch from the side lines and not get dirty with the rest of us.
Wes was a master mechanic before he was 21. He owns 2 garages in FL. The guys knows cars, and he knows forced induction.
Jessee is one of our guys, who offered to put his jeep on the operating table in the name of science. LOL. Jess was an excellent sport and was just as busy with the install as the other guys.
Here's a shot of Jessee as he opened the Turbo.

More turbo shots.
This was happening the night before the turbo install.
The next morning, we started at 8am and finished about 12 hours later.

Dan and Wes from Prodigy show up around 8am... With an intercooler.
Turns out, this is going to be the first public Stage 2 Installation
Attachment 869
Once the pleasantries were exchanged, it was go time.
In these situations, I stay out of the way mostly and try to get the camera in where I can. Pete and Wes start tearing the jeep down. Intake, out. Manifold out.

Got to get the gaskets out intact.

This is Pete addressing the coolant hoses that run into the firewall. New prodigy hoses will be rerouted to include the turbo.

Here is Pete re routing the fuel line with the injectors
Attachment 878
I bet it's gonna be a rocket ship. Its gonna beat the Maggie and be close to the Ripp. Which is on top will have to be seen. But done right it should have a fat torque curve.
Jesse's Girl is pretty darn quick. I'm amazed at how problem-free the install and first 200+ miles went by. I drove home right after install, just over 200 miles at highway speed. Even with 37s and 4.88s I have passing power well past 80mph. Nasty!
it sat for a couple days after I got home and parked it. I went out to inspect everything this morning and still leak-free. I figured I'd be losing some fluid somewhere with the new routing of pipes and heat cycling of all of the system components. Definitely pleased with it thus far.
I burped the cooling system, which had air in it after install. This is an iterative process that I think I'll be doing a couple more times. The running temperature did drop a bit after a ride this morning so I think I have it mostly air-free. I'll check in a day or so and repeat the process.
Looking forward to the numbers on this. Snarf77, what kind of fuel mileage did you get on the way home? And how did it compare to before the install?
Here's some silicone spray on the fuel line

We also modded the bracket for the stock intake to make room for the turbo
Attachment 880
Here's a shot of the scene from outside. All power modded jeeps accounted for. BB with the RIPP, Sweet Pea with the Mag, and Jesse's Girl on the operating table.

Next we tackle the oil pan. The system is drained, and we unbolt the pan, Then we get a chisel in there, and break it away from the underside of the engine.
Attachment 882
Attachment 883
Once removed, we needed to clean the pan's surface that touches the engine, and the engine's surface that touches the pan. Get it ready for new RTV
Attachment 884
The step drill comes next to mod the pan to receive the oil back from the turbo. Forced by gravity.

It was cool the way you did this on instagram and facebook.
Is there a sound byte coming?
Yes a sound byte is on the way.
Here's the first vid!

my first review of the turbo driving is next.
I am in a process of ordering one. Already had a talk with Dan Mara VP prodigy , hope everything goes well.
There's a new kit with a ball bearing turbo water cooled coming soon.
Thanks Ross and Jeff for the info's.
Hope to get a technical supports internationally once needed
When do we get to hear that blow-off valve? I'm interested to hear how it sounds compared to my stage 1 kit (which has not blow-off valve) when shifting gears.
Its a hard sound to capture, as you have to be shifting on the throttle. Making the noise is easy, its getting a camera to pick it up that's hard.
We'll see if there is a way to get a mic close enough. The sound is plain as day when you drive. Total pressurized air sound. ShPSSSSSSSST!!!
You could try the technique I used in my video: record a video with your phone, holding the phone in your left hand against the steering wheel.
Turn the volume up and listen closely when I shift to 2nd during the acceleration that starts around 1:25: https://www.youtube.com/watch?v=2cyAZSDR_m8#t=1m25s
There's the "ssshhhHHHHHH" sound of the wastegate as I accelerate, then a "PUuuhhh" sound when I lift off the throttle to change gears. I expect the BOV will replace my "PUuuhhh" with a much more distinct "PSSHHhhh".
More pics!
We are stripping out the old down, and y pipes from Jessee's JK

Modding the fan shroud to make room in the front of the engine bay... just a tiny trim

Here we are feeding the new pipes down to the main exhaust.

I love the sound effects in quotations. I can only describe my acceleration sound as the noise an airplane engine makes when starting up, a higher pitched whir, not quite a whistle, but a whir! The release of throttle for a gear shift definitely has a satisfying "pluhhh--whoooshhh". :)
This is like those commercials where a person is explaining to their mechanic the noise their suspect car is making!
Has a date with the dyno been scheduled yet?
Looks like Prodigy ran their Jeep, Jesse's Girl should run REAL well!
Attachment 904
I still don't trust Prodigy's stock dyno run. Torque is too high, and peak power is too low and reached at too low of an RPM. The Pentastar has a nearly flat torque curve from 1800 rpm to redline, and all other stock dyno results agree that peak power happens at redline (6400 RPM), and that the peak power number is higher than the peak torque number.
Look at JeepLab's stock dyno results for comparison:
http://jeeplab.com/attachment.php?at...0&d=1394927642
http://jeeplab.com/attachment.php?at...6&d=1394666617
JeepLab shows torque at 175 ft-lbs vs Prodigy at 203 ft-lbs. JeeLab shows power at 189 hp @ 6400 rpm vs Prodigy at 170 hp @ ~5000 rpm.
Also, according to their dyno charts, stage 2 turbo (and therefore also stage 1) has a LOSS of torque/power below 2800 RPM. My but dyno does not agree with this. It feels similar to stock around 2000 rpm to me, with noticeable gains before 2500 RPM.
I wonder what causes that sudden drop in torque at 6200 rpm on the stage 2 dyno...
Can't wait to see JeepLab's stage 2 dyno results compared to JeepLab's stock dyno results for a second opinion.
I haven't studied the dyno graph too well but I have always been of the mindset that as long as you test the before and after on the same dyno and similar conditions that is what really matters and should give you the actual gains. I understand what you are saying but every jeep is different, how corrections are applied to the dyno and such. Regarding the sudden drop at 6200rpm, I thought I heard it mentioned that the speed limiter was hit?
I am very excited to read the full review, with driving impression video!
Variations between jeeps (or dyno calibrations, or local atmospheric conditions) will not cause a major difference in the shape of the torque/power curves. With a stock jeep, peak power should always come at/near redline, and should have a higher value than the peak torque value.
The sudden drop at 6200 I'm referring to is on the stage 2 dyno. The speed limiter is not an issue with the turbo tune installed (stock speed limit is lifted by the tune).
You are reading that right. It doesn't seem right to me, and their entire stock torque/power curve doesn't make sense to me either, as I mentioned here:
http://jeeplab.com/showthread.php?14...ull=1#post2228
And here:
http://jeeplab.com/showthread.php?33...=1260#post1260
The stage 2's sudden dropoff at 6200 rpm also doesn't make sense. The stage 1 turbo makes more tq/power than what is shown in that chart above 6200. I suspect the dyno operator may have prematurely lifted the throttle near redline. I'm waiting for a response from Prodigy about both of these points of confusion.
