I'm on my phone trying to upload them . Let me know if they still are not showing up.
NOLA is your jeep "DOZER"?
i like the color.
BTW - I just went out and looked at that black cylinder on the side of the A/C condenser again. I pushed on it carefully and was able to actually bend it back a bit such that it held its new position. I think this may give me the room I need for the intercooler. I'll test fit it again sometime after the weekend and report back.
NOLA did they cut the metalic portion to fit the IC hoses?
Turbo guys, and everyone else. What are you doing to keep your temps under the hood down? Ive got the poison spyder hood louver, turbo blanket, and Im going to wrap the turbo exhaust pipe this weekend with DEI Lava wraps. Ive noticed its really hot under my hood. Yes of course because of the turbo and the piping, but i thought the hood louver would reduced the temps more. It does a pretty good job, i can see the heat waves coming out from the vents. But Im still noticing a lot of heat even with the blanket and the louver. It also doesnt help that i live in New Orleans and its super humid down here. Let me know what you guys are doing or if you have any other suggestions.
My Temp needle sits right at the middle. I know this is just a dummy gauge, im not concerned about the engine overheating thats not the issue. Just with the added mods (turbo down pipe right at the front of the engine) causing excessive heat inside the engine bay. I wrapped the down pipe with Titanium exhaust wrap and that made a big difference in the reduction of heat in the engine bay. It was a pain in the ass wrapping the tube inside the engine... No room! took about 2hours. But well worth it. Ill post pics. And just a quick update on the stage 2. Its FAST! noticeable power gain from the stage 1 upgrade! And with the new tune the jeep is running better and better each time prodigy release a new tune. Still data logging and sending it to prodigy for their R&D. Ill get some vids inside the cab as well as outside. And the Gauges are AWESomE! i would recommend boost gauge and the wide band gauge.
Here are some pics of the temp guage and inside of the cab.Attachment 1018Attachment 1019
Nola , thats awesome. I have 2 questions:
1- can we see a picture of where the boost sensor installed.
2- The place of radiator recovery tank pic.
NOLA is your dyno chart coming? I'd like to see how it turns out compared to JG
I have the metalcloak aluminum fender liners that replaced the plastic stock liners. They allow much more air movement within the engine compartment and through the engine compartment without really exposing the engine compartment to additional mud and grime when wheeling (to my surprise).
My hood is also fiberglass/carbon fiber with a scoop. I feel it really forces the air into the engine compartment and (maybe) down and out the fender wells.
That being said, the engine compartment is very warm when not moving. It doesn't affect engine temps but its enough to throw off my outside air temperature sensor while standing still. It will read hotter than the weather until I get moving again for a bit. No biggie.
Cant get the jeep in DYNO mode..Both of the shops i have taken the jeep to have not been able to dyno the jeep in 2wheel drive. It will not shift out of 1st gear when on the dyno in 2wheel drive. Southernhotrod, the shop that did my stage 2 install could not get any answers from Diablo or Prodigy on how to get the computer to get in dyno mode. If anyone knows how to get around this please let me know. 2012 jeep wrangler jku automatic.

Here is a picture of the recovery tank.. They installed in pretty close to ether the stock tank was located, just off to the left some (our left). If you follow the over flow hose you can see the black tank right behind the fan shroud. I'll get a pic of the the boost sensor install. I just need to know what I'm looking for?? Lol.

Can you provide any details about how that recovery tank is mounted there? I'm not thrilled with the low behind-the-bumper position that Prodigy intends for it.
Thanks Nola for pictures. Usually boost sensor comes after the throttle body. So it might be fitted on the intake beneath the engine cover.
Pickles, I'll take pictures of the set up. I'll get them this evening.
jeepsking: An existing hard plastic vacuum line for the "purge control valve" is replaced with a vacuum hose with 2 "T" fittings. The wastegate and BOV sensing lines connect to the two T's on that vacuum line.
http://www.miataturbo.net/attachment...need-ebc-2-gif
Given the above diagram, both the wastegate and BOV are connected to "C" using a vacuum line shared with each other and the purge control valve.
This is not the ideal setup.
Ideally, the BOV should have its own dedicated line connected directly to the intake manifold, rather than teed into an existing line. Having a dedicated line ensures the quickest possible response of the BOV.
The wastegate should ideally not be connected to a vacuum source. Even TiAL (manufacturer of the wastegate) specifically says to use a pre-throttle-body boost source. It should be connected to either "A" or "B" in the diagram. Here's a good read about wastegate boost source options: http://www.miataturbo.net/diy-turbo-...eed-ebc-47532/
Post #15 in that thread specifically talks about why the wastegate should NOT be connected to the intake manifold (position "C" in the diagram).
I have asked Prodigy about this, and they say they have zero issues with their setup. Also, they say they tested the wastegate boost source both before (position "B" ) and after (position "C") the throttle body and found no difference. They chose position "C" and shared vacuum lines for ease of installation.
I'm not too concerned about the BOV having its own dedicated vacuum line. If the BOV responds quickly with a shared line, then it's fine.
I'm more concerned about the potential part throttle issues with the wastegate being connected to position "C" (see post #15 in the linked thread above).
Connecting the wastegate to the intake manifold seems to be a controversial subject on the internet. Many people on forums say they have run that way for years with no problems. Other people report part-throttle drivability issues and part-throttle high load compressor surge (like when driving up a long hill). Some people say the intake manifold source will give you quicker spooling and faster throttle response. I'm sure the exact outcome depends on many factors and the entire turbo/engine system as a whole. I've read many threads on the topic and talked to both TiAL and Prodigy directly. Based on all of that, I have concluded for myself that there's no good reason to disregard TiAL's instructions to specifically use a pre-throttle-body boost-only (no vacuum) source to control the wastegate.
For this reason, I decided to order one of these that I will use to add a boost source to the silicone coupler/elbow that connects to the throttle body (position "B" in the diagram):

It's a very simple/inexpensive modification to make me happy that I've done it the "right way". I will probably try both the Prodigy setup and my modified setup to see if I notice any differences.
Thanks Jeff for these info's. What about the boost sensor pick up point to the gauge. As far as I know it should be in position "C".
Oh, yeah. Boost gauge should always be at position "C". Ideally, each component should have its own dedicated line, rather than using T fittings to split/share lines to a vacuum/boost source. But that would require adding new barbed hose fittings to the intake manifold for the BOV and boost gauge. I haven't found any good info on how to add fittings to a plastic intake manifold yet.

This what your looking for? Looks like they used the T fitting method.
Yes it is. So adding T fitting gives inaccurate boost reading?
Not inaccurate. Just potentially slower response, and probably on the scale of hundredths of a second difference. It wouldn't matter at all for the boost gauge. For the BOV, as long as it responds quickly enough to avoid compressor surge, then the T fitting for that is fine too. A dedicated vacuum source for the BOV might possibly keep the turbo spooled a bit better during gear changes, but whether or not the difference is worth the effort of creating a dedicated vacuum source would require testing and data logging to determine.
Testing and Data logging! Yeah!
staying spooled with the turbo is my main concern with it. If there was a way to blend an sc with a turbo, so that it worked of the engine low, and exhaust high it would solve all problems.
Work that out, will you pickles?
That's called "twincharging": http://en.wikipedia.org/wiki/Twincharger
It's very complex to get it done right. I would not want to be the one to try to combine a turbo kit with a supercharger kit on a previously non-boosted engine and get it all working/tuned properly. I would also not want to pay the bill for a performance shop to figure it all out. It appears that the Magnuson supercharger would be physically compatible with the Prodigy turbo. Who wants to try it?
NOLA Jeeper!
werent you going to dyno?
Hi all,
Been reading the posts for sometime, became a member last week and posting for the first time.
Ordered my Prodigy stage 2, and can't wait to install it, would love to read more feedback. It kinda went all quite.
Anyone doing an instal on an Auto jk?
WELCOME!
It did kinda go quiet. Here is the current status, Jesse is away in a training seminar, that our turbo. NOLA, you have an update on your unit?
Also, with the auto, Wes from prodigy told us that the auto is the faster option as the turbo spools up and stays spooled as the tranny shifts. Not clutch, not power loss. When you get your turbo installed, tell us if you agree.
Thnx JeepLab,
Sure I will, I don't know when it will ship out, but I'm already clearing up my garage and cleaning up my tools....lol getting really excited with the prep work.
Also got the Titanium wrap, heat control is going to be a challenge for me here. So any more useful tips on that will be great.
Anyone managed to fit a snorkel? would really like to use my snorkel it will help with the heat issue.
I'm doing this instal solo!! So I'm taking notes of all the trials from you and from UselessPickles who has been good with his write up on the instal.
Also if anyone has any advise on exhaust mods.
There was also some talk about Prodigy getting a cat-back exhaust system custom designed for use with their turbo kit.
I'm quite happy with the turbo and stock exhaust combination. During normal gentle driving and steady cruising, there are no sounds that would cause anyone to suspect that my Jeep has any performance mods.
That is also a good point U.P, but any compromise on performance?
