Engine & DrivetrainDiscussions about the engine and drivetrain of your vehicle.
This is a discussion thread titled "supercharger", within the Engine & Drivetrain forum, part of the Technical & Vehicle Assistance Forums category.
I had my dealer install the TRD supercharger, and I burn 93 octane gas as they recomend. But on anything close to wide open throttle, I can hear a substantial engine knock (ping). Any help or recomendations. Thanks.
Might want to do a quick search on this topic..this board has tons of useful information.
As for the ping-- what kind of plugs are you using?
Somebody help me if I'm wrong...but I believe the stock fuel pressure regulator runs off of a vacuum line. There is a way to connect a T fitting into a boost line running off the S/C. You then replace the vacuum line going into the FPR with a line running off the T fitting from the boost line. What this does is allow the fuel pressure regulator to flow more fuel at WOT. Its good for a couple extra PSI in the fuel line, and is now the standard setup on the 3.4L TRD S/C. I used to have a S/C Tacoma and remember setting up the FPR this way. My 3.4L S/C never had any problems pinging using this setup and 92 octane fuel. Try doing a search on this info, I beleive someone already posted this fix. It would be worth the try and wouldn't cost or hurt anything.

Check out my photos. I have done exactly what your talking about. It is called "boost port additions" or close to that.. anyway.. you will see!

I don't have an answer to your problem with pinging. I think it sounds like detonation. I had a similiar issue with an F150 V8 that always pinged when I went to full throttle while still using 93 octance fuel.
I have a Toyota Tundra 01 (4.7L) currently and was thinking of upgrading to the TRD Supercharger but I've heard that pinging is a problem. Have you seen a substantial increase in HP and torque? As far as driving goes, how does your truck perform as a daily driver? Thanks.

Search for my posts on here, and you'll see all my ping woes.
Methanol is my only fixture to major ping. BTW, I hear it a lot more than you do, but I have yet to get a check engine light out of it.
By the way, does anyone else notice that the truck runs better at 3/4 throttle that it does at WOT?
Last night on my way home from work, at a stop sign, I wanted to give a good pull to see if I could make it ping (with my 5% methanol mix) and it broke the tires lose.. It's never done that on dry ground before... It was kinda nice.. I had to peddle it, but I got it going about 3/4 throttle, and it actually ran really nice.. I could feel it pulling the whole time, it didn't lay down at all.
When I make my return trip to the drag strip to re-test the truck with the blower I'll be hard pressed to run it WOT...
At least the track wont lie, I'll know how it runs best after a couple passes.

Yep... I DO! It is the SAME feeling I get. It runs better the LESS I mash the gas. I geuss mine is in the 1/2 to 3/4 range. Shifts smoother and pulls the whole time. If I go WOT.. then it really dissapoints. Noticed it blowing black smoke out the pipe when it started to stumble. Like all of a sudden, someone put a 5th wheel behind me. That is how I describe it.

I break my tires constantly at 3/4 and I have 285's and LSD! DITTO on 3/4 performance though. It almost feels that when you go WOT in between powerbands or 1-3rd gear. The ECU is dragging behind, but i guess that is the woes of having force induction. You have to learn how to drive a s/c or turbo different. KNow when you can spool up the fastest. I would like to sit in someones truck who has a unichip piggybacking.

Thats fuel cutoff... The ECU goes into fuel cutoff before the shift. I don't notice it has bad as you describe, but it does stuble a little on shift.
I am almost there! I spoke to Jack today as a matter of fact and it is getting close. I am ON THE LIST. I will make the TRD PIGGYBACK ECU work better as a frisbee or door stop. I believe it is ment for that. I will dyno B4 and After.
I will also post pics and leave a detailed account out here for all to see.
I am not done by a long shot. Just an observation... My O2 went out about a month ago. I was worried... Then, spoke to David (Toyota Tech buddy) and he told me that it makes NO DIFF on the ECU, that it is just running on a fixed fuel map, insted of a dynamic map. Basically, OPEN LOOP vs. CLOSED LOOP. So, ok.
I have done some monitoring, and my mileage has gone UP slightly. From 14.3 to 15.1 on AVG!!! Imagine that?
Hmmmmm...

Unichip? Just unplug your ECU, and you'll feel what the truck can do.. Just don't expect it to last too long. Toyota of Santa Maria is rebuilding trannys in the Tundra left and right, and this is just the normal trucks. (Mine is the first Supercharged Tundra they've seen). According to TRD, the dead-shift is because they broke tranny's, input shafts, etc during development. Scott, do you make 5psi at 3/4 or is it less? TRD offers a 4psi pulley for $35. (Or free if you b***h about ping enough).

I can't.. The only car I've seen 15+ in is my wife's 99 Rav.. We'd get 30 in that. And like a dummy I traded it for a Highlander. Twice the payment and half the milage.
I must be a sucky driver, milage is just something I can't get.
Max is 6PSI, 5 and some change at 3/4 throttle. I know what your referring to on the tranny. SMOKED 2nd clutch pack on my Tacoma when I did all this to it as well. Learned my lesson. I will have the tranny reworked at Level 10 and be able to pump up the volume. You have to look at the whole drive line.
The A340E is a good tranny, just too sloppy in the shifts and too much heat buildup. It WILL toast a clutch pack.
