General Supercharger Thread

Either way, it looks like zipping the tunes/logs will allow us to share them here as well as comparing the differences in HPT so that we can make our own edits to the tune we're running with the caveat that the tune being shared is unlocked. If it isn't, we won't even be able to look at the tables.

 

Sonnax Zip Kit and Line Pressure Booster ordered...

My ECU ID lacks most of the transmission options to tune with, so I think the Sonnax kit is a good place to start. Thanks @pursuit2550 for leading the way and helping me get a few things sorted out. Hoping to install over Christmas or New Years after I've finished up a few projects at work and have some downtime with the truck.

Luckily, my recent transmission D&F looked pretty good (visually) so I'm hoping this is more preventative than anything. I'm also very curious to inspect the VB for wear; I'm sure there are worn parts, I just want to know WHAT parts and HOW MUCH..

 

I'm injecting 500cc after maf before throttle body. Only using a 70/30 w/m mix on a single nozzle. It's a simple setup but aqua mist with multiple injectors would be ideal.
In spring I'll be opening my hood right above the radiator with vents/louvers.

 

We can add any changes you want in the background. Send me a message with what you want in any specific table and I can make those edits “behind the scenes” even if you don’t have access.

 

They dropped my IAT delta, I'm happy with them.

 

I emailed them but have not heard back on thelead time for the aluminum spacer. Guess i could call. What was yours? Thanks!

 

<cannon fodder post>

113k miles on trk
88k miles on Harrop S/C

changed plugs
changed coolant.
changed pads & rotors.

still using the 77.5mm pulley
stock intake
stock TRD exhaust

truck is running awesome.

still getting 17mpg avg.

IAT delta is still 31 degrees. Harrop sensor.
but,
the IAT delta is 34 degrees if I turn off A/C compressor. It's cooler in Houston now.

trans still pinned...hover ~ 165 degrees no matter what. maxed at 185 in Houston slo-ass traffic.

MAP (boost) @ 62mph cruise = -10.5

because I'm still on the 80mm tune, boost still comes on before PE.
I can hit 6.5lbs before PE - on ramps & such.
other than that, the tune is primo.
AFR will still drop to low 10's in PE.

Cal-Trac traction bars are typical...Houston is cooling off & I need to adjust them again.

5k oil changes & it burns ZERO oil.

still using Costco 5w-30.
will try Valvoline restore & protect next round...the oil geek channel said it works.

 

I got the aluminum version, anodized black. I specified in the notes when purchasing, but was emailing them back and forth beforehand.

 

6.5 psi before PE hits should get you a free update on your tune.

Is that your first change of plugs?

 

I’d be pissed, wouldn’t want the truck in boost with it that lean.

 

yes, first change of plugs

 

it's my fault.

I changed the pulley...and have been too lazy to bring it back to re-tune.

my work around is to just hit the pedal a smidge harder, then PE happens.

 

I feel better about mine occasionally hitting 1 or 2 psi before pe at lower elevation now

 

Yeah just be careful. My biggest concern would be towing. Enough throttle to get into boost while towing but not enough to get fueling right. Easy tune change though…so worth an email ask to your tuner asking if he can reduce PE TPS and get you closer to aligning boost and PE when on throttle

 

Yeah wouldn’t worry about that. Again unless it’s for prolonged instances. Ie towing up a mountain pass at 1-2 psi and 14.7 afr

 

you're right.

I just emailed him for a re-tune.

 

It would be a good time to do the magnuson airbox w/ SABM and TRD accelerator too! Plus any other mods you may be eyeing. Might save a few bucks on future tuning adjustments.

 

Another valve body option for us out of Australia. I believe this is compatible with the tundra trans as well. Pretty sure they make an electronic converter lockup switch as well to lock it on demand.

stop.

just stop.

 

I had seen that awhile back. IPT made a metion on one of his videos/website that he was the only one moding AB60 VB.

 

I feel the same way. Always something

 

SABM is pretty cheap and easy as far as mods go

 

Im going to try and learn more about it. I’d like to do something, may go this route. Initial thoughts is they look like a reputable company and I’ve started watching this install video which looks promising. Reviews on the other options seem hit or miss. Haven’t seen a bad review on this one yet but will keep an eye out. https://m.youtube.com/watch?v=DxbvobUqcI8&pp=ygUYVHVuZHJhIG5vbWFkIHZhbHZlICBib2R5

 

Does it make a big difference on our SC?

 

That's the video I saw when looking into mods for our VBs.

 

I don't know if it makes a BIG difference, but more airflow is always a good thing. There's a big thread on here somewhere about it and I dont recall ever seeing any negative results

 

Sticker shock averted...

With mine, I noticed a little bit more intake noise at the airbox as I approach 0psi. More available metered air isn't usually a bad thing, particularly at elevation.
