General Supercharger Thread

Thank you for investigating this product. That is great info to know.

 

Anybody know how to soften up the 2-3 shift with HPT? It really slams into gear at higher load/rpm compared to the others.

 

I’m callin BS on that one. Have you seen a stock cat light barely gets through lol.

 

I'm not sure what cell count it would be equivalent to.
I opted to run 200 cell metal catalyst that were welded in place. Concerning the heat, rich afr and pressure against a ceramic catalyst it will eventually fail.

Edit:*I haven't seen too many threads where the Toyota cats failed. What is considered high flow these days? I did not see what the cpsi is for the Tundra cats.

 

I'm not 100% sure if there is. Only saw and messed with torque pressures for command throttle under engine torque trans.
I was taught quick clutch engagement eliminated clutch packs from getting burnt.

 

I haven’t personally done this - or even tried, really- but over on the HPT forum I recall seeing SlowNStock taking about pulling timing right before the shift as an OE strategy to softening shifts without increasing shift time or decreasing line pressure and risking trans clutches. I will see what I can find but perhaps look in that direction.

 

I had the hard 2-3 shift try this per SlowNStock. Works like a charm

 

Another option besides the above might be to increase torque reduction for 2-3 shift

 

Could very well be.
Hi flow cats also tend to be of smaller diameter (mine almost look straight piped) vs the broad OEM cats. Oldish post from @dirtydeeds

Fuck me! 6100rpms!?

My present truck has never seen 4500rpm's!

I just want a SC to help with towing over a few mountain passes. I'm gonna have a hard time doing WOTs for a tune base.

Am I in the wrong thread?

 

Keith built me a mid pipe, he used Nissan Titan cats, they lasted two weeks after installing them and my long tune header's on my 2012 SC Tundra.

 

You and @nobodyintexas can compete for "buying a supercharger but never getting into boost" the most

 

But for real, it will help with towing immensely.

 

Right thread! You're going to have to rip to make sure your tune is dialed in especially power enrichment. I've hit 6k so much I've lost countlol

 

You could always set up your tune to have the redline at 4500rpm.

In my mind, that’s kind of like marrying a supermodel and then not wanting to see her naked.

 

I see what you are putting down

 

I married one..problem is SHE doesn't want to see ME NAKED

 

This is me!

 

I have a set of high flow cats on my new set up, hopefully they last longer, I will keep the stock cats on stand by.

 

I had one set with a metal catalyst implode and clog on bank 1. I have a set of old 200 cell magnaflow cats that were fully welded for the catalyst cells and have held up for the past 8 years.

 

Oh, you are in the right thread all right! The truck is a great towing platform out of the box. With a supercharger, it is an insanely good towing platform. That’s why I SC my truck and it has already proved itself to me in that regard. And you don’t need 6k rpm to tow with. 8k enclosed - no problem holding 5th at 65mph. At over a mile altitude. 4th for the climbs, but 5th is easy. Seriously, my mind was blown. I “knew” the SC helped with towing, but I really didn’t KNOW how much it helped. Now I do.

So get one already

This is honesty the biggest worry I’ve had about aftermarket cats: too many stories about high flow aftermarket cats that take a dump shortly after install or throwing CELs, while the shop just “tossed” the OE cats and you get to foot the bill for new, Uber expensive OE cats.

 

thank you for the info! So I understand that running a speedo correction has no bearing on the SC tune? I’m assuming that it being a separate system they will play nice and not interfere with each other?

 

Correct

 

FIFY

 

I'm using a o2 sensor bung extender, hopefully that helps with any CEL.

 

Who here has installed their own?

I down loaded the install PDF from Sparks and printed it out so as to see the pics better.

Reading the manual several times, I see nothing real technical doing an install.

I have my own shop and lift, so dropping the tank is not a big deal.

 

I installed my Harrop, nothing that difficult other than the weight of the SC. I used an engine hoist to lower the SC onto the engine. Also, I'd recommend getting a metric thread chasing kit to clean the threads in the head before installing the bolts.

 

I just installed my 2650 maggy kit. Wasnt bad at all

 

Anyone know what the pulley bolts tourqe specs for the maggy 2650 are?
