TRD supercharger availability update

Yea, it happens. Its just liquid being pumped, it makes that noise.

 

Glad I'm not the only one

 

That was when I got to work this morning. I have a 12 min drive to work. Every trip to and from work I can hear that.

Let me know if you cannot hear it and I can pop the hood and try to capture the sound from under there. I haven't listened to it with the hood up yet but I'm 95% sure its coming from the small reservoir on the drivers side of the engine bay.

 

Bump for any answers

 

How full should the reservoir be? I dont recall seeing a full line or anything.

 

I think mine is about half full is all. I will add some more and get it to at least 3/4 full and see what happens.

 

You know. I have seen this before an I am not necessarily supporting it, because I know the damage it does and can do over time namely to the catalytic converters, but on GM models (specifically LSx and LQ equipped vehicles, so performance and trucks/SUV's) they have an integrated feature that handles the AFR called "Lean Cruise." It essentially enables all their huge V8's to obtain the 23-30MPG you see them regularly achieving easily. I am wondering if there is a way to make that a possibility on our Tacoma's. The fuel savings on the highway would be pretty nice, because as of right now, I notice that on all highway unless you are on accel. or decel. the target AFR is always 14.7 no matter what.

 

Maybe tunning on the urd ecu can do that

 

That's quite a bit to spend on the Ucon just to get a different cruise AFR, unless there is another way to get the tuning done without getting a new ECU?

 

Dealer installed at 1 mile. I just got the truck in November and have noticed the sound since I bought it. I have put about 2,000 miles on it since then. I am around 18,500 miles on the truck. I did have a clamp leaking slightly that came off that reservoir. I installed a new clamp. It wasn't dripping leaking so I don't think I lost that much coolant but probably just enough to make it low.

I will top off the coolant and see if the "problem" persists. I will update this thread when I do. I dont have any coolant at home, only dex-cool so it may be a few days.

 

I'm sure there are several ways you could go about it. I'm thinking maybe a switchable maf calibrator or something. I think you'd want more than an AFR to monitor it though. Cylinder head temp? Maybe EGT? Don't know.
I'm not a tuning guru though, just spit balling.

 

Sub'd. Gimme my damn S/C!

 

This is the entire reason why I want one too... "Midsize" is no excuse for inadequate power. These engines don't cut it when it comes time to tow 5,000 lbs (well within specs) at highway speeds.

 

Yes, you'd at least want to monitor EGT at a minimum.

That is the target stoichiometric air fuel ratio for gasoline's best efficiency, while in Closed loop. That is what you want the AFR to be.

Keep the cruising AFR the same. Adjust the Open Loop AFR's and timing.

 

I thought they were doing some "improvements" to the blower but I see its advertising the same HP and TQ that the TRD kit originally did. Just cant justify that price tag for the gains. If it was WHP then I would be all over this new kit, but from what I've read it would take a lot more to reach 300whp with the TRD kit.

 

Well, not a whole lot IIRC. @Torspd has dynographs of TRD-supercharged Tacomas with some fairly simple bolt-ons that reach 300rwhp.

I know it's not a one-stop drop in 300rwhp mod though.
