General Supercharger Thread

Agree with that too, hard to quantify how much the valve body actually does. Though the fact it can prolong a slipping transmission and make it not slip for at least a few months indicates to me it does do SOMETHING at least.

 

How you drive has a lot to do with it also. Low speed lugging the motor with a heavy load will burn it out. Lots of frequent full throttle downshifts will as well.

 

I think the VB is an ounce of prevention worth a pound of cure type thing. If you from the beginning have more clamping force on the clutches, they never get a chance to wear/glaze over and cause irreversible damage. Will the VB totally prevent that, I doubt it. I’m sure it helps greatly especially the sooner you do it in the transmissions life especially post SC install.

 

agree but a vb can't make your clutches grab harder. only more clutches can improve holding capacity. clean fluid is going to be the best thing anyone can do besides a vb upgrade or built trans.

the reason a new vb (we talk about upgraded prolonging life, but in reality it's likely because you're installing a new vb regardless of the potential upgrades done to it) helps is because now it can hold line pressures with no leaks. I would venture to say you will get the same 'prolonged life' from your trans regardless if you replace your VB with OEM new / OEM reman / pick a company that offers an upgraded VB.

additionally, if you cannot find a way to modify torque management, none of it matters anyway.

 

I replaced my slipping trans in 2013. I ran a modified shift kit and had the line pressure raised internally. I was not kind to it and I installed an IPT valve body in 2023. It is still holding on. I do plenty of wot runs up to 5600- 6400rpm and tow maybe a ton of gravel and other stuff occasionally. I do change my fluid every year or two.

 

that fluid change frequency is, in my opinion, the best piece of data there. IPT VB helps for sure, but clean fluid always in the trans keeps your VB from eating itself. If the VB is working well, you won't burn up clutches as quick as it's engaging and disengaging when being requested because the LP comes up when needed.

 

Sent an oil analysis to Blackstone on April 17th and it just finally was delivered today per USPS. Damn near “lost” the package in Philly for a month. Had to file a missing mail search that took forever. Waiting on Blackstone to confirm they have it in their possession.

If my oil/engine comes back in good health then I’ll be stepping down to the smaller pulley, long tube headers and bigger injections and whatever else we can do along with the new VB I have at my house.

Going to go back to National Speed again as they did my original install. (unfortunately have to go to NC because VA is closed they said due to landlord upping rent).

Fingers Crossed for good engine health. lol and I said after I put on King 3.0s and 37s I’d be done for a while.

 

send it

 

This may have been discussed in the past, but were transmissions short lived in the Tundras that had Toyota installed Magnusson chargers under the TRD umbrella? Or was it a different transmission back then, or was it simply because they had no additional modifications to make more power/torque?

 

Not sure TBD, but I don't think at that point people were pushing them as hard as today. Canned tune and kit components and I think stock trans held up fine. It's the smaller pulley with more boost, more fuel, better tune that gets more out of the equation that pushes the trans too hard. Towing hard effects that too, even in stock form. Just depends, I think, how the truck is used and maintained.

 

Kinda. If it’s already started slipping, ain’t much you can do about it other than baby it til it dies. VB helps prolong it, but transmissions use friction material that will wear out at some point. 5k, 50k, 500k… all depends on how you abuse it

Not preaching against a VB or shift kit by any means as that has always been mod1 on any of my Chevy or ford vehicles. Just that in the case of Sniv’s pals, they took a dead horse and breathed a little extra life in to it. It works best when the horse is still alive, though.

 

lol you're not wrong. vb is great but it's just a new part in a worn trans. good till it wears or the already worn trans shits the bed regardless of the new vb

 

More clutches increases holding capacity is true. More line pressure which is the result of the built valve body increases the force on the clutch packs is also true. More line pressure should give less slip and firmer engagement. The built VBs also use billet valves and o-rings like the sonnax components that don’t wear out as quickly as OEM components and seal better.

 

More line pressure should help to counteract slipping, but will only try to make up grip by pressure vs actual grip via the clutches. if the material is already worn then the vb will help but it's a losing battle. not saying you're wrong, as I agree. Just playing devils advocate here saying regarding of people's VB choice, it's just adding a new component into a trans only built (in new or reman form with new clutches) for 500weel max (or whatever that number might be). Built VB is def better than new OEM VB. But either one into a trans that is NOT new, you will likely have the same result of needing a new trans IF you work your truck hard via hard pulls or heavy towing.

 

So that’s the funny thing about it… AFAIK, most of the rebuilders don’t do much of that on an AB60. They stack maybe one extra clutch/steel into a clutch pack or two, but hard parts aren’t upgraded like you would in a 4l60 that has some notoriously weak parts, so it’s only soft parts that can change type or quality, but not quantity or function. At least that’s what I’ve gathered looking in to built AB60’s. Not disagreeing, just playing devils advocate

 

They all use the same rebuild kits. I did find more heavy duty clutches is all.

IPT uses these as well as other builders.

 

I just know I’ll take my chances with a 1k VB over 7k trans for as long as it’s an option lol. Not sure about WAT, but IPT doesn’t charge you for the built VB portion of the trans if you end up needing a rebuild after installing their VB.

 

Yep exactly

 

Yeah I guess if you current have no issues then why not. Any sign of issue and I’d just get a built trans. But to each their own. Different strokes for different folks

 

Agreed. My trans only had 72k on it, 25k supercharged. And the fluid was flushed, not drain and filled twice in that time. I had no signs of a failing VB or trans when I installed the WAT VB. Hopefully it stays that way.

 

I made a 47re dodge transmission with nothing but a valvebody live behind a 1000ftlb Cummins drag racing and burn outs for almost a 100k miles. Don’t lug it, don’t do full throttle downshifts, keep the fluid clean. A valvebody alone can do wonders to save a transmission if you don’t abuse it.

 

I just started my valvebody install and being a 2020 with 43k miles my fluid was shot.

 

Just posting this for the sake of data.
~45k miles Transmission drain and fill/new filter
~80k miles TVS1900 installed then started doing upgrades for more power. Pulley/pump/injectors, etc.
~103k miles TVS2650 went on and a smaller pulley right away
~106k miles The stock transmission died. All forward gears were slipping massively. I don't do any towing of significance but run a lot of 7% grades pretty hard.
~106k miles The IPT built transmission went in.
~111.5k miles First transmission drain and fill.
I may do another 5k drain and fill and then go to 10ks. We'll see.

 

While true I never had a Ford that someone recommended i get SuperCharged.
It wasnt until I started driving Toyotas that it came up.
Seems it's more common with Toyotas.

 

I think Toyota TRD (Magnuson) superchargers have been around since the mid 1990's. Not sure any of the local 3 have had long term supercharger partnerships at all

 

My 98 Tacoma was my first SuperCharged Toyota.
Dont know if they had them before that.
But I dont think so.

 

I had a 97 S/C'd Tacoma.

 

Camden Superchargers made kits for the R series engines in the 1980’s, and possibly earlier. The company has been around since the 50’s, and amazingly still produces kits for the old 22R and RE.

 

You can still pin open your '21...

In fact, it's required when doing a transmission drain n fill service to obtain proper fill levels, etc... and many have pinned them open prior to getting their coolers installed and see a consistent drop in trans temps.

This video shows what you're pinning open on the '19-'21s (I tried to que the video at the proper time, but if not just FF to about 4:30)...
