    Very good info. jives with my transmission 1-2 shift. it's better than stock, but still has a mechanical softness.

    I added zero oil to it - as it has yet to burn oil.

    since $26.50 for 10 qts fits my budget & I change oil every ~5k, Kirkland is now my lube.

    I'm sure there are better oils out there, but this'll do.

    Curious if anyone can educate me on the intercooler pump running after engine shutdown. I’ve always only locked the truck once when getting out but for some reason my wife has a bad habit of locking the vehicle twice. Not sure if it’s OCD related or what, but she says it shuts the headlights off if they were on after the second lock. I’ve tried explaining that turbos and superchargers need to cool after engine shutdown, but I realized I didn’t really know the reasoning behind it…at least not enough to speak intelligently about it. Can anyone shed some light on this so I can hopefully try to break this habit of hers shutting the intercooler pump off prematurely? Thanks guys!

    My Magnuson only runs when the ignition is on, so instant key is out it's off, Harrop obviously is fancier then. I don't see the point of running after shut down for a supercharger, for a turbo they get insanely hot and you don't want the pump to stop when the turbo is still hot or it can fry the oil that's trapped in it. Lots of superchargers have no cooling at all, and since a supercharger isn't driven by a hot exhaust it runs a lot cooler in general. You can put your hand on the supercharger, you can't out your hand on a turbo. Someone correct me if I'm wrong, but a supercharger doesn't get hot enough where it needs further cooling after running where as a turbo can suffer damage if it doesn't cool to an allowable temperature.

    I don’t think my IC pump runs on my Harrop after shut down. It only runs with ignition on. Like @snivilous said I don’t see any reason for the supercharger needing a “cool down” like a turbo, since it’s just Intake air passing through it and not hot exhaust gas. Really even the intercooler is only needed at all when you’re doing some decent pulls under boost for sustained periods and the heat of compression of the air makes it necessary to cool it down. Under regular driving throttle it’s just bypassing, so there isn’t really any heat buildup.

    ditto

    if your IC pump is running when your engine is off, you are doing something wrong.

    Wonder if the shop wired it into the wrong circuit then. Glad to know it’s a non-issue. It seems like it runs for precisely the amount of time it takes for the auto headlights to shut off. I’ll check with Harrop and see if this is “normal” behavior. Maybe they’ve changed something…thanks guys!

    Maybe they tapped into the headlight fuse. I wouldn't worry about it either way, not hurting anything by running for an extra 30 seconds. Though I would check that it is indeed running when the truck is on, if it's tied into the headlights and the headlights are off the pump might be off...

    I did some temperature measurement some time ago using an infrared thermometer and no part of the intercooler or blower reached above 100-120°F. not really even close, I was surprised. That isn't going to cook the little bit of oil in the blower...

    let me expound On a fine example of the Diderot effect:

    Remember how I told y’all the wife like driving the tundra? Well it was time to replace her 2011 Lexus

    she wanted something sporty

    we have a Tesla plaid now

    Once this giant sinus infection clears I’ll hammer the tundra in hopes to hit 5.0 0-60

    then post a plaid number. It’s insane.

    so...it looks like the HP advantage of the Tesla carries out thru the times. as we get faster the HP shows even more.

    I don't have a road to do a 1/4 mile - this car will do 150 in the 1/4. too fast for my blood.

    This is my 5.47 run in the Tundra - I'm still going to try to keep up with some of y'all's big numbers.

    we had 4 adults in the Plaid for this run. Grown ass adults. yes, they all screamed. and yes, it hurt my sinus infection.

    I'm fairly certain if it was only me in there & I put it in Cheetah stance, I could do 2.1 imagine that. 2.1 in a 4 door family sedan.

    Got the install done. No issues except it is a little lean under boost. Gonna have to get it scanned to check the ethanol number in the ECU. I have never run E85 in it though so I don't see how it could be affecting it.

    What kind of AFRs is everyone seeing? I am getting around 13 on my wideband.

    Nice! Welcome to the club. When you say you’re seeing around 13 under boost, Is that at WOT or just when it’s making a little boost? The only AFR you should be concerned with is at WOT and mine is very erratic but mostly hangs in the 10s/11s. I still think there’s something wrong with my wideband gauge but I’m going to see if a good tune smooths out my readings.

    ditto.

    mine goes to 11.9 under boost...but that's the minimum on the narrow band, it may be dipping lower. it hangs around 14.5 otherwise. I use a scanguage.

    under heavy boost, she will noticeably cough up soot. so it must be damn rich under boost.

    How about at 60-70% throttle making 5-6 lbs of boost? What AFR do you see? I am staying right around 14 which scares me. I can't get to the tuner until next week so I am just driving it easy, for now.

    You must understand, its going to be that high at anything other than WOT or damn near close to it because otherwise it’s running closed loop. At WOT it goes to open loop, and thats when it stops trying to maintain that 14.7ish AFR and just dumps fuel. Check it at WOT and then report back, that’s the only thing that matters. Don’t sweat the AFR being high under part throttle driving, that’s what the computer is programmed to shoot for in those conditions.

    Not necessarily. Over a certain throttle percentage the afr should start richening out. It's not like it only goes rich at WOT, there's a ramp into the WOT AFR. At 60-70% throttle the TRD tune has already ramped into the power enrichment (AFR richening) cycle. The stock TRD tune starts PE at 45% throttle iirc (it might be 45deg throttle angle, which is ~50% throttle, I forget).

    To reiterate what mine does, around the time I start seeing any boost it starts to richen. No boost = 14.7, 1psi is around 13:1 and WOT is 10.7ish. This is kind of blind shooting, but when I had my tune setup (and setup my previous tune) I wanted to be safe and run too rich too early so there was no chance of getting hot. If you're at 13:1 at WOT it's way too lean, if you're at 13:1 at 70% throttle I wouldn't be too worried, though 6psi at 13:1 sounds pretty lean for that much boost, though I'm no expert.

    I’ve read the stock tune doesn’t go to open loop until 80% throttle. Not saying it won’t start to richen up some before that as you are saying. For example while towing up hills I’ve seen mine hang around 13 while not much above 50% throttle and at several pounds of boost. Bottom line is, he’s not going to blow his engine doing a 3-4 second pull at WOT to check the AFR even if it was leaner around 13-14. And he definitely isn’t going to hurt it at part throttle. If he doesn’t check WOT he won’t know. A full 1/4 mile run down the drag strip at 14 isn’t going to be good of course.

    I agree he should be fine doing a pull to see where it's at. I don't know what the stock tune runs, just know what the TRD one came with and it's ballpark what other people have suggested. I don't know how much boost requires how much extra fuel, but in my mind more boost = more heat/power = dump more fuel.

    I'm cautious though :D

    I just peeked at a few of my tunes. On the S/C tunes, the Throttle Threshold for Wide Open Fuel Target Active is set from 40-50% depending on the tune. N/A starts at just over 70% for reference...FWTW.

    The threshold differences as noted by snivilous and wyndedd I think do highlight the need for tuning stage 1 for long term reliability. But I wouldn’t be worried about having some WOT fun with it until getting it tuned. Sounds to me that to be safe and ensure you’re not running too lean under load, you either have to be driving with light throttle or WOT everywhere you go to make sure it’s rich enough… “Honey why are you driving so fast!!!”….”I gotta keep that AFR in the sweet spot woman!”

    And remember that base S/C tunes are going to error on the side of rich/safe at WOT because that's what a lot of people are interested in....because it's so much dang fun.

    I put my wideband on the truck a few weeks before the sc. I noticed that around 70% throttle it would richen into the 12s pre sc. Now at wot with boost it is around 13.1. I don't stay there more than 3-4 seconds as I do not want to hurt the motor. I really just want to compare to other untuned trucks as I am sure a tune will change it. Don't understand why Harrop tells us that the stock ECU will handle the sc.
