URD 5th Gen Supercharger Thread

Any more updates? Especially with the 4th gear issue? I am debating Magnuson versus URD and would love to hear more. My local shop is pushing Magnuson. I'm looking for a S/C to help me when driving on I-70 in Colorado up the mountains and keeping in 5th gear and doing +70MPH.

I get the 4th gear issue when I accelerate hard to about 60mph and let off. I called and spoke to gadget from urd he said it could be an issue with the gyro in the 4Runner with the added power of the supercharger. It’s making the car think it’s going up a hill with a hard acceleration and therefore hanging up. He also said a zero gyro calibration would fix this but would require pulling the ucon ecu and plugging back in the factory ecu to do so. Propbably would take a couple hours to complete. Besides the 4th gear problem under that circumstance, I took my 4Runner from New York to Florida and back last month with zero issues.

Friggin idiot I saw you’ve got the urd ypipe. How do you like it with the supercharger kit installed? I was thinking about picking one up and maybe putting on the urd exhaust too
 
EDIT: After about 2 weeks, I noticed the coolant reservoir looked low, so I refilled it... several times! Apparently it was VERY low, and hence the proper amount of coolant was not being circulated through the intercooler and heat exchanger. Since refilling the million tiny dwarfs have returned.

What has URD to say about loosing all those dwarfs :sadwave:

I am considering which one to get and if the party in the engine compartment is too loud it will affect my choice
:drummer: :party:

I never contacted URD about the sound of a million tiny dwarfs. The mechanic who installed it said it is a normal sound for a twin screw style supercharger, and standard on all Whipple chargers he has worked on, OEM or aftermarket.
You cannot hear it from inside the passenger compartment, only outside the vehicle and only at idle in Park. Obviously as a single person I've never stood outside of my own vehicle with it in gear, so can't say how much you can hear it sitting at the stop light.

The URD Y-pipe and Mk3 Stainless were a real PITA to get right. I ended up going back 9 times to fix leaks. In the end we welded the muffler in place on both sides, cut the Y-pipe on under the tranny and added a flex pipe, added a high-flow cat to the mid-pipe, changed to a side exit tailpipe so I could use the rear window, several fixes for clamps coming loose, and issues with the axle pipe hitting the frame.
If I had to do again, I might do the Y-pipe, absolutely skip the headers (I'm still fighting CEL/Codes), and if you need a cat-back get a side exit from the start ignoring URD's completely (even if it is the only 3 inch). It's currently sealed tightly, quiet at idle and cruising <70mph, but too loud for my liking under even light acceleration or load. If you're considering the y-pipe and other exhaust mods, do the Y-pipe only first and see if you still think you need a cat-back. I'd leave the manifolds alone, just not worth the hassle.

Read this as I'm very happy with the URD/Whipple SC and power it produces. Both my mechanic and I are absolutely dissatisfied and fed up with their exhaust.

starting to think my mk3 stainless has leaks, hence the drone.. lol.
 
What shop are you using? I'm out in the mtns and don't have a shop but would like a S/C as well. Leaning towards the URD

I'm in Colorado too... interested in more power but not sure about emissions issues? Does anyone have any input on this?

Can you or anyone else PM me the install instructions for this? I have a tacoma and gadget is draggin his heals making this fit them. i may just have to do it myself.

If anyone want to sell theirs Im willing to buy. Gadget will only go down $500 in price of total price for just the blower. I dont need any other parts.
 
Question for those with the kit: How did your MPGs fare after installing this kit, particularly on 91 octane?

I was getting almost 19 on stock nittos running 93 octane with a heavy foot. I’ve installed wheel spacers, larger tires and a gobi stealth rack and I’m getting 16.3 now
 
Any news on the dwarves? Is the sound really not noticeable from the cabin, or do you just choose to block it out?

I'm currently debating which SC system to get, and would love to get some more feedback from the URD users.

MORE UPDATES PLEASE!

Thanks!
 
my supercharger developed a leak, Gadget at URD was great and got me a rebuilt unit. He really took care of me on this.

But bad news is that the UCon-EMS engine management that comes with the URD interferes with how NYS does OBD2 vehicle inspections. Driving my 4runner around with a expired inspection.. until a fix is out. hopefully there will be one.

My Maestro-RR for the head unit has an option to force OBD-II to always enabled so that both it and the UCon-EMS are both usable. Maybe they can try that for their inspection.

I have the maestro-rr since way when they first released their first product as a beta tester. Well aware of what it can and cannot do.

Gadget over at URD is aware of the issue and it has something to do with the way the signal is modified over the canbus.
 
I am debating Magnuson vs URD whipple.

I want to read up more on how people are doing with the URD...

I read this whole thread, i definitely know more now than i did before i read it..

Seems like not a lot of people have the URD sc..

I live near Chicago Illinois in NW Indiana and would only do a sc if i had a really good shop for installs and tuning out and fixing bugs that would come later..

Someone told me to call Chicago 4 x 4 i am still trying to reach them..

Definitely would love to find a good install shop that can also custom dyno tune...

I would even be willing to take my 4runner all the way to see Gadget in Maryland so they can do the install and a "possible" custom dyno tune but when i was picking his brain over the phone the other week it seemed like he was not really interested to do install at his shop nor dyno tunes.. so that kinda leaves me hanging..

Like where would i go if i had a problem..

The problem with after market mods and stuff is having a reliable shop around when you need them..

What are the best shops in the US for our Toyota truck mods??

The whipple setup is pretty much self tuning. There are probably some parameters that can be adjusted with the piggyback ecu. But for the most part i think it tunes itself. I think any shop that does custom dyno tuning will be able to access the piggyback and get it done.

The whipple itself has some custom parts on it from URD but also can be fixed by any competent mechanic that has ever disassembled a whipple.

Gadget stands by his product. I can tell you that much. He took care of shipping both ways on my supercharger when he swapped it out for me. This is on a 2 year old URD supercharger.
 
Just curious if OBD2 emissions is still an issue with the UCON EMS? I read earlier in the thread that there was an issue with OBD readiness monitors, but not sure if UCON did any updates to fix the issue.

Considering adding a supercharger later this year, but since we have emissions testing in Colorado, that itself would be a deal breaker for the URD.

i think it was just the NYS emissions test that had a issue. They give you a little patch or teach you how to make one for emissions test. Plug into usb everytime you do the Emissions test.

Thanks for the info.

I am not sure how the NYS emissions works, but they do a full OBD2 check here in colorado and sometimes also smog you on the dyno. So with that USB device it will pass obd2 emissions with no issues?
