TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

It may help slightly but probably not much. Most likely the rich part throttle is happening right at the point of open loop.
Also if you have any boost happening at that point you will be even richer due to the fpr mod.
Intake manifold porting and larger throttle body will mainly effect top end not mid range. It may help a little bit mainly due to a more efficient path in the lower im but the stock im is of sufficient size for mid range air flow requirements

 

Hahahaha!!!

Same my bruddah!

We need a video of said change good sir!

Let's be honest here, there aren't a whole lot of trucks that can hang with us, base supercharge, most likely, but not after all the power added and stuff we are all rocking.

Besides, the only trucks I can't think that would stand a snowballs chance in hell would be a Lightning F-150, a SS Silverado, and a supercharged Tundra.

 

That is a good point. I really would like a find a way to lean this thing out at part throttle, but the only way to do that is to undo the FPR mod and with a 2.3 pulley the stock injectors would explode from the 130% duty cycle. Hahaha.

 

It's amazing. I throw mine one basically every time I'm on dirt. I have the locker anytime as well as the abs/ traction control off and always choose the locker anytime. As you get faster off road, though using it makes you slide a little more often, it makes sliding much much more predictable.

 

Let me get my partner in crime @crashnburn80 to do the filming. He and I will be doing the pulley swap.

 

Add meth my man. It solves all problems....I think.

 

I require leaner activity at part throttle, adding meth into the mix would only wash things down even further and as rich as that would be I'd probably end up throwing a rod or doing some major damage. Lolol.

 

You can check to see if you are in boost (just a little boost) when it goes rich then remove fpr mod to test.
See if goes as rich, more rich, or less rich at the crossover point. Just dont get on it because at your level certainly very bad things would happen!

It's so simple to do you might as well try it just so you know if that is the cause of the condition.

 

My favorite quote:

"I spent all my money on women, booze, and fast cars. The rest I just squandered."

 

Gladly. I know a few places that will not attract unwanted attention.

 

I have observed my AFR's before at part throttle pre-FPR mod and post and I have found a drastic improvement in the numbers in pre-FPR configuration. The reason why it goes so rich is as you mentioned open loop plus boost build up and fuel pressure increase.

I wonder if there is a way to have best of both worlds, utilize FPR mod only in WOT and remove it in all other circumstances prior. Almost like a bypass of sorts. Which uses max boost to switch over vacuum source.

 

Yep. Those ford boys get awful jealous.

 

I'm sure there is some sort of pressure sensing device out there that could be implemented but would most likely be a crude way of getting the desired results.
Tuning obviously would be the best method.
Do you have everything needed to tweak the tune yourself or are you still waiting on something from OVTune?

 

Yes there is a way. Use a NOS TPS switch to activate a vacuum solendoid valve.

A Toyota VSV may work for that, but I’m not sure without testing one. You’d want a valve with 3 ports. 2 normally connected ports where one side switches over when the solenoid is activated.




Then you activate it only at WOT with one of these:

Yeah tuning would definitely be the best method. I literally have everything needed to tune my own truck, I literally do not even know how to do a datalog on it though that's the problem.

Oh hell. I never even thought of that!

 

yes its a 76mm

 

I increased my AFR’s about 0.2 going from 65mm to 70mm on the TB pre pulley change.

 

I have all tuning equipment as well. Ovtune sent me a link to techstream and said 'download this and use it'. Which I did but it asks for dealership information. I dont have that, or an email response from ovtune. So, here I sit with Oh-Novtune.

 

Thus the reason I have not purchased. It seems like a great tool, but I don’t really think 2nd gen Tacos are a priority.

 

If I had patience like you I wouldn't be a grand deep in it. I'd be surprised if we ever hear from him.
