TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

The harder side of hard rock

 

How long are they supposed to last?

 

Ill take a cd

Unless there is digital form

 

As long as they can until they start to fail lol. But with the load of ur motor
I would say it’s about time. Truck Probly went into limp mode to protect your “cats”

 

Check the A/F sensor wires. One of my extensions shorted and it did the exact same thing. Truck just fell on its face. I am running the extensions to locate the A/F at the merge and not on the center cylinder. The extension melted and shorted out. Just an idea.

 

Correction. Just looked at the charts again, 404wftlbs and 341whp. Not exactly the number you quoted but you were closest anyways.

Temperature was 70 degrees with 80% humidity.

 

Waiting on graphs... I want to see what rpm peak torque and hp was at and what it looked like way up high in the rpm range.

 

And don’t get down on your self those are still great numbers. And if you had those numbers and it wasn’t running 100% then you no it is only gonna make more next time.

 

We are in the process of mixing our disc, soon it will be available on all streaming platforms so I’ll let you know when it’s up.

 

I'd like to hear that playing in the intro of your next utube video!

 

I does have the techmology to make that happen.

 

Very odd. You'll get it sorted. Check spark plugs perhaps?

 

Yes I got some data logs, going to take some more shortly since the logs are only from the 'good' runs that I was able to complete.

And yeah, will check plugs this week.

 

Let me guess, P0351 - P0356 accompanied potentially by P0300?

How many miles do you have?

I actually thought you would get higher HP than that. Still really good but considering you are making all that boost, I thought at least 380 - 400 for sure.

We should collectively group buy this dude a prize for guessing right.

 

Yes on the codes except no P0300.

150k kilometres which is 90000 miles.

 

Check plugs for sure. Of course given the mileage it sort of sounds like you ran into a case of bad luck and have failing coils. Pretty common on Toyotas. I would not even mess around with it (especially given how annoying coil access is on our trucks) and replace all 6 along with plugs (if you choose to and they look decent and not too fouled out) and call it a day. Once you get one failing coil and replace it alone it's a pretty good indicator that the rest will follow suit shortly as the secondary ignition components all wear at the same rate.

 

I just had this issue on my work truck. P0300, p0304, p0354.
This is what the plugs looked like compared to new. Yikes

 

I’ll probably replace the coils, but talking with the dyno guy who is a pretty experienced tuner-car guy, he said the coil pack codes don’t necessarily mean the coil packs are bad, and misfiring could be the cause of said coil packs electrical discharge changed due to something else causing a misfire...?

 

You got all the use out of those plugs.
