S/C kit from URD for the 4Runner 4.7L V8!!

Just got off the phone with Brian at URD and he confirmed to me that they are in the process of designing a supercharger kit SPECIFICALLY FOR THE 4RUNNER utilizing the Rotrex blower (amazing piece of engineering) for the 4.7L 2UZ-FE V8 engine. He said the kit will offer 6-7 psi of boost and that the rod failure issue is a "non-issue", not sure how but that's what he said.

He made it sound like it is to be completed sooner rather than later. Let's keep bugging them to see when a release date might happen then possibly organize a group buy.

I don't know any other details, so I recommend contacting him if you have questions.

I guess I'm the only one excited about this...

I am excited too...Just not too enthused with a rod blowing through my hood. I want to see what warranty they offer.

this rod bearing issue that everyone was all up in arms about was poor tuning on part by the user. Prior to having the correct ECU released for the 4Runner V8, some people were using the Tundra/Sequoia TRD piggyback and blowing the engine, that was the problem.

Tuning and correct fuel maps are key.

i can't wait!!!

I see...Not too smart on their part.

The Tundra engine gained 80 rwhp at 5psi!!! With a better breathing engine and 6-7psi boost for the 4R any ideas what they are projecting?

Im interested....very interested. Connor, did they say when its going to be done with testing? Im calling them tomorrow if i have time to speak to them about issues with the kit as well as the componets used. Being in Vegas, I need to ENSURE that they are going to be taking serious steps for preignition/detonation as well as heat soak issues with the Rotrex Cseries blowers.

Ditto. The last thing I want is to be driving down the freeway in 115 degree heat and have my engine melt!

I think the kit is still in the developmental stages, but its definitely worth asking. The smaller blower allowed for an air-water intercooler in the V6, so hopefully they'll find room for one in our kit.

Rob, make sure you sure the details of your phone call with us...

didnt get to talk to them today but their number is stored in my phone for tomorrows chat with them.

Im going to make damn sure of issues with high temps and how they are going to deal with them. I would love to see a aquamist system integrated into the whole deal to help combat CHT's and all.

UPDATE:

Attempted to call URD today...Called 4times. One call for Sales and one call for Customer Service both times I tried today. No answer both times at two differnt times of the day. Im not impressed thus far. Ill try them again tomorrow and if i get no answer, i will leave a message and email them.

They are probably too busy fielding the calls from the rest of us!!

Left a message today and Brian from URD called me and left a message back. He had little information since they have yet to officially offer a kit for the truck. I want to talk to them IN PERSON on the phone as I have some questions I want answered. Ill try them again tomorrow.

Hmm, I'm potentially interested as well if it would work for the 2003 V8 as well. Well, I hope it comes soon. Too damn hard to find the TRD S/C for the '03

I had a rod failure, and it was before the TRD sc helped it out. So i'm not sure about the wrong ecu being at fault. Whenever theres been a failure, its the number 2 and 7 rods and/or bearings. Too much of a coincedence.

Hey Rob,
Any word from URD?

I am very interested. Having built and run turbo charged cars with stand alone ECU's, Anti-Lag, air-air and air-fluid intercoolers...........all in 100+ degree California summers I may also be able to help with development. That said these guys have been successful with their other superchargers. I would actually suggest one person take point for us all on the board and that we not bug them. The last thing we want to do is give them the impression that we are a difficult bunch to deal with. If they feel they will burn a lot of time support our chargers because we seem difficult they could drop the whole thing. I know cause I have been on another forum where just something happened.

Regarding the warm weather folk, the biggest mistake I have seen is where people do not listen to their knock sensors (i.e. watch the light or read the ECU code), get greedy and turn up the boost. In my rally car I could run 25psi during the winter. Before I got my stand alone ECU , when the temps got above about 85 degrees I backed down to 22psi, if it was over 100 I backed down to 17psi. Each PSI was worth about 10HP and lots of torque and yes is sucked to loose the power (25psi-17psi= ~80HP). But while other around me were blowing up motors with less than 30k miles on them mine went 192k miles without ever having the head off or the bottom end out. Once I got my stand alone ECU I simply told it to add fuel, pul timing and if needed pull boost if it heard knock. This worked great because I could just drive the car. I was conservative with my settings and never had an issue. Sometimes though, on very hot days, I would not get more than 15psi, price I paid for bad CA gas and summer weather.

As for intercoolers the best street setup I have seen is one that used fluid (not water) and is hooked into the A/C system. It uses the A/C system to cool the fluid to REALLY cool temps, then pumps that fluid into the intercooler where it REALLY chills the intake charge. The up side here is that it provides the most cooling to the intake charge possible (like using icewater, but it stays cool as long as your cars A/C works) and it permits very short intake plumbing, especially vs. air-air setups. The down side is you loose about 10hp turn the a/c compressor at low speeds (more than made up for with the cool intake charge). At high speed and large throttle openings the ECU shuts off the a/c compressor on al new cars automatically, so that 10HP loss vanishes. The another down side is you need to tap into the a/c lines (pretty easy) and you need a fluid tank to be mounted somewhere. The last downside I see is that someone here or at URD would need to make their own plumbing for the air intakes.

naw bro..everytime i try to call, it just goes straight to voice mail. I wanna talk to someone in person. They must only have like 2 sales people.

its a month later any new news?
