TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

I'm doing the nose bearing/seal/coupler replacement at 234k miles on my 2009 DCLB TRD Sport. I noticed the upper idlers were rough, so I pressed in new 6303 bearings. I had my parts cleaned and laid out well for easy re-assembly. At some point the tray holding my upper idlers, spacers, and mounting plate got moved. Does anyone have a picture or diagram there the tophat bearing spacers go?? I'm at a bit of a loss as I've searched for a couple hours and found nothing. TIA!

 

For the resident experts: I'm nearing the end of my SC install and didn't think about how much bigger the SC intake is compared to OEM. With that being said, is it standard to have to trim the arm of the AFE Intake? Quick measurement shows roughly an inch too long? If cutting is the way, any tips/tricks on how to do it and what cutting tool makes the most sense? Just don't want to jack up my intake. Thanks!

 

Intake shouldnt be effected by the supercharger. The supercharger is made to be used with the OEM intake without modification so you shouldnt have to modify it

 

Thanks

Thanks but I don't have the stock OEM intake.
I have an AFE Stage 2. It's def a tighter fit than with the OEM plenum mounted.

I understand but it shouldnt. The supercharger puts the throttle body in the same position as the stock plenum. Must be an issue with how your intake is mounted

 

I was rushing through the other night. I'll give it another look. Thanks!

 

Pretty sure the TRD is trimmed to fit. On the intake tube there are. Couple of ridges for stock and other.

 

I ran their momentum GT with no issues

Biggest mistake I've made in the last few years was selling this truck!

 

Likely this! The AFE intake box fender port was really snug against the fender wall. I had to push with everything I had to get it to seat properly. You can see in the pic posted above, that there's very little room left between the TB and Intake tube

 

URD 2.825 Pulley and CSF Radiator installed today. Now fully ready for a tune to get rid of these pesky MAF warnings.

 

What puller is this? I'm having a time with this duralast one that I got from Auto Zone.

 

OTC 464 2-Ton 'GripLock' –

$95 OTC 464 2-Ton 'GripLock' External and Internal Puller

https://www.amazon.com/gp/product/B004CGUAHG?ie=UTF8&th=1 Worked like a charm although it's $80. If you happen to live around Seattle you're welcome to borrow it.

 

Thanks, but I'm a long way from there, very much appreciated and thanks for the link!

 

Does anyone have any recommendations on a billet oil pump/rotor assembly upgrade? About to replace my upper oil pan due to a puncture and going to overhaul a few things while I'm in there.

Wasn't able to find any direct 1grfe kits but see alot of 2zz and some 2gr but unsure of compatibility. Information is little to be found. Tia!

 

I was also thinking about this recently. I was gonna see if boundary could cook something up? What else have you seen out there? I have an extra gearset on hand I could send wherever.

 

ha, i asked the same thing before scrolling down and seeing your post. Last few 3 ton pullers I got from the auto store felt like they'd explode! I had to use the 6 ton puller

 

I have the Craftsman 3 jaw puller. It's a beast.

 

I could use some help interpreting some data with HPTuner Scanner. I am running the +Throttle tune. Going to revert to Standard to see if I can understand this better.
While capturing some data logs with HPTuner I am seeing a max Accelerator Pedal Position of ~75%/ Throttle Position 80.8%. Both Throttle Desired Angle and Throttle Driver Demand are at 84 degrees. Logging with the truck not running, just in ACC position and trying to relearn the pedal position sensor, I peak at 80.8% and 84* before the Accelerator reaches 75%. I am not sure if this is an artifact of the +Throttle mapping. In both cases the latter values peak before the Accelerator Pedal Position reaches that max of 75%.

I shared the logs with my tuner of me running at WOT, I hit +8 lbs of boost, up to ~5k RPMs. When he reviews the logs it says I'm only hitting 45.4% pedal input and 61.5 deg throttle blade. Even though I am to the floor. I verified the pedal is physically bottoming out.
The logs have no other indications of issue with the truck, It just does not appear that I am seeing max opening of the TB and Pedal. I just had the S/C off and the TB looked clean. I could give it a spray down. Hitting such exact values repeatedly does not indicate to me it is gunked up. My AFR does not dip below 12 right now, which is not correlating with logged values. I have read both banks with different sensors, same PLX module, and they agree with each other. Something is not aligning up here. If the throttle is truly not opening all the way, then I would expect the demand to not require AFR of below 12.

Are these numbers expected with this tune? Could it be the Throttle position sensor or pedal sensor? After doing a relearn of the of the pedal sensor I saw no improvement.
On a maybe related note, I am experiencing low idle conditions when applying brakes, sometimes below 500RPMs. Could be a vacuum leak at the brake booster?

 

As I indicated to you in our email exchange the Throttle Position PID reporting % assumes a 0-5v input, but it is not 0-5v in output. So you’re not going to see 100%

84° of TB opening in this platform is “wide open” if you can and are achieving that, you're throttle body is is achieving full throtle.

Your Log:


An actual WOT log.

 

That makes sense.
I'm still struggling with the 75% limit with the pedal smashed to the floor.
And when I review the logs I see higher values of the pedal position. I don't know how to remedy the discrepancy of me flooring it with the logs not agreeing with it.
Yesterday I was shy to bring it up to redline with the AFR appearing too high. But in both these examples the legal position shows less than 100% but the throttle angle is maxed at 84*

Hope you don't consider this a call out, I'm trying to learn so I can remedy the discrepancy. You've been very helpful.
