General Supercharger Thread

Not yet, but there's a good thread going on tuning a GM TB to eventually take advantage of this. Haven't been able to overcome the driveability with that large of a TB...yet.

 

Quick question, if I grab this powertrax
https://www.stage3motorsports.com/gt501536-07-21-tundra-powertrax-grip-pro-traction-system.html
can I just drop the diff, pull the old lsd out without messing with the gears/shims and put in the new powertrax, and bolt her back up? Or am I going to have to mess with the gears and shims inevitably?

 

Are you speaking of the "initial development and prototyping 102mm...." thread? I've been looking it over. I saw someone asked a similar question but I never saw a solid response. I figure with the D2A it should be operational just need a good tune?

 

Nope.

 

Nope I have to f with the gears and shims or nope I don’t have to

 

Won't be as simple as a swap, if you get lucky you might not need to adjust shims, but will need to remove brakes to pull the axles, and swap the ring over to the powertrax.

 

You'll need to have it set up correctly, or bad things happen that will cost you money.

 

I was thinking of getting that unit, but controlling the larger TB with a tune is new territory on these trucks and challenging.

 

Fine with doing all but shims lol just don’t want to mess with it. So you’re saying it’s possible…

 

You shouldn’t need to mess with pinion depth, which is a PITA. The backlash will need to measured and possibly adjusted, though it does have a chance of being in spec. The carrier bearing shims are a crap ton easier to adjust/swap, if required.

 

You could get lucky with the spacing, but I would get an install kit with shims, proper tools, etc. just in case you don't get lucky.

 

Ok I’ll order with a kit so I have shims on hand if needed. We will see. I guess worst the truck is parked for a bit.

 

Side note. This any one of you guys?

 

Fuel related: I haven't heard anyone talk about this, but if more fuel is needed why not swap an aeromotive 525 into a Delphi pump module? It looks like it should fit.

I bought a Delphi when I was doing my S/C thinking it was the "best" option come to find out the pump was different.




I ended up buying a stock replacement module just so it would be new instead of my dirty ass 200k+ mile module. Then I started thinking what I could do with it and saw the 525.


Should be an easy swap, but I honestly know nothing.

 

Just FYI



But obviously if you can't properly control it then that can be a bit of a problem. I've seen Viktor's set up on YouTube and this seems like it could save some space up front. Then just throw on something like this and be good to go

 

Oh yeah, I know it physically mounts up, tuning for more than a track truck is another story...but others are working on it, so there is hope!

 

I mean if you live outside certain counties in TX and don't need emissions testing couldn't you just get a plug and play motec/haltec and do whatever? I'm talking out my ass because I have no idea about tuning etc just trying to learn realistic possibilities. Not even sure if a stand alone even controls the TB lol

 

I installed my auburn in a few hours. Benching that carrier at 2am was fun! Got lucky and backlash was withing spec on first go.

 

The biggest hurdle is setting up your torque load/airload/shift speed/and adjusting the TB vs throttle position. I'm running the GM 95mm TB. When I set the throttle position reduced by 50 percent I had a few hard starts. Not sure if it was ecu or? Reduced it down to 40 percent and is running alright. Still fine tuning torque/shifting. I had issues with a crappy 103mm. Viktor didn't fine tune his and was ok with the high shift rpm at the drag strip. Going motec/ stand alone might have better tunability.

 

I originally installed the aermotive 340. It fit but had to hack the canisterforbit to sit right. I was able to fit a walbro 450 model 267 in a ffv canister in a non ffv tundra. You'll also need to upgrade your fuel lines to take advantage of the extra fuel. At least -8AN supply teeing off to -6AN for each bank.
I'm just running both -6AN supply and return.

 

I’m selling the 103 mm Harrop inlet snout. If you are interested, message me. I can’t see anyone needing a 110mm on a Tundra unless you are going for 1000+ hp, but if you end up going that route, it would be cool to see!

 

A moose is probably more powerful than a horse, so I’ll go with 800 wmp any day

 

I mean 1000+hp does have a nice ring to it haha. I know I'm not the only one with that dream in mind. Time will tell and this forum will be my go-to for many things.

On the bright side I did get the go ahead from the boss for ANYTHING I want to do to the truck so there is a 6.8L fully built xat motor in my future.

 

had a challenge this morning. stoplight @ FM225/BW8

hopped up F250 powerstrokes are spunky.

not spunky enough tho.


I wonder what these folks think when a bone stock looking '20 Tundra moves ahead?

 

Ref the convo about which pump comes with mag 2650.
SCOL reached out to mag. SCOL thinks it might be the same pump as the 1900 kit. Do we know what that it? mag said they don’t know what pump they include. SCOL is sure it’s denso but hasn’t given any flow rates. Will report back once I have some answers.

 

I love spanking "racecarZ" in my ginormous, lifted, big tired Tree.

lol

 

Had a similar situation last week. Powerstroke attempted to do the roll coal thing on me and he proceeded to get freight trained. I also look completely stock, down to the oem trd cat back

Edit: I guess the headers show if you look hard enough

 

Be interesting to see the specs from the manufacturer. We only know @ViktorG testing which was around 196lph for the denso TRD supplies one for the 1900.

 

I’d be shocked if my fuel pump can only flow 196lph given I’m running rich enough at max dc with 650’s on the 76 pulley producing 12psi. I was really thinking more like 340lph. It would make much more sense with how the truck has responded with afr’s upgrading from 535 to 650

If the flow rate is 196lph, that can only provide enough flow for the green 535’s at 70% dc at 3bar… and 650’s at 57% dc. All of that would mean my truck wouldn’t get any richer by upgrading injectors.

Does that make sense? 1900 users are only able to get 70% in dc from the pump provided in the mag kit?

 

This is a debate that can be easily solved by disconnecting the feed line to the rail, sticking it into a bucket, supplying the pump with 12 volts and using a stopwatch to measure the volume over time.
The 196 lph was measured at the outlet of the FPR, so it is a lower value than what the pump would supply to the rails since the FPR is a restriction. I just had no other way of keeping the pressure at 43 psi at that time. From personal experience the original TRD blower supplied pump maxed out before the injectors did on a couple of friends’ trucks I dyno tuned. These is a good chance the pump supplied with the Maggy kit now is a different model that flows more, but until someone tests it, it will just be an endless internet debate. If someone ships me their Maggy pump that they are not using, I can flow test it.
