TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Is it me or does the Ford ranger look like a mini van from the front

 

I saw the 20th one Ive seen yesterday and they are so ugly IMO. At least the chevy has the zr2 that doesnt look horrible

 

Wouldn't surprise me if it was made in the same factory.

 

Ego uninflated brother. This thread is just legitimate and we all know it. It definitely is like a "what did you do to your Toyota today PRO" version like previously mentioned.

We have the heaviest hitters as far as technical guys who are signed up on this forum hanging out in here and posting on a regular basis. That alone makes for really good conversation, (not to mention the best troubleshooting tips which can be offered) not just light bars, lifts, and the usual BS this forum sees.

410 g/s. Following a 1.0 rule that would indicate you are making some 410 HP AT THE CRANK. Because sure, your intake may be seeing that sort of power build up, but once that power is said and done and put to the ground it would be notably less if you deduct 10-15% from that.

Based on what you have seen power wise I don't have any reason to believe that your engine is on the fritz, nor do you have any compression losses due to poorly sealing valves, or excessive blowby.

 

Cams

 

Do a compression test as a health check.

 

Ok fellas.
I took off the vacuum line from the back of the sc that goes to the diaphragm thing out the back. I then plugged and blocked the that outlet in the back of the sc.
I now have full boost all the way to red line!
So what does this mean? Is it ok to just leave it the way it is now or is it unhealthy to do that?

 

Proves what we were suspecting. Your bypass valve is not working properly. A new one is needed, if you want well mannered light cruising driving.

 

And has the smile come off your face?

 

If I understand you correctly, the bypass valve is now always closed. So you’ll see worse fuel economy at cruising, as the other posters said.

I’d take off the valve completely and hook a hand vacuum pump up to the line connected to the valve, pull a vacuum on it, then pump it up above atmospheric a few (or 8) psi and see what it does, I.e does it open and close when it’s supposed to. Then you’ll know for sure the valve needs replacement.

In the meantime, glad you have the funness back.

 

That’s it! So is the bypass valve the part where the vacuum line goes into yes? Behind the sc? It’s it something that can be fixed or just buy a new one?

 

Haha! Your dead right! I was bloody stoked when the rpm went all the way to red line!

 

Yes that right. The valve is now always closed. I can tell it’s always closed too so when I’m not on the gas I can still here the sc winding down.
I don’t have a vacuum pump to test that out but I’ll ask my mechanic if I can borrow his if he has one.
If it’s is not working properly, it’s it an adjustment to be made or just buy a new one?

 

It sounds like when it is connected to the manifold pressure, it opens when it reaches a certain positive boost level, which is not correct operation. When you pull a vacuum on the valve, it should start opening almost right away; when you pressure it up, it should stay closed no matter how high the pressure goes.

 

When the lone is connected I have boost from idle up to around 3000rpm and the there is no boost. So yes your right in saying it’s not correct operation. It needs to stay closed while still under vacuum. So either the adjustment is wrong or the bypass valve is stuffed.

 

Ya. Stuffed for sure. Chances are good you’ll be changing it with a new one based on what happened when you plugged the line.

 

So where is the best place to find one of those? Being down here is Aus, I might be best to contact my local Toyota dealer and see if they can track one down for me.
Or is it worth me asking URD?

 

I think someone posted a while back that you can contact Magnuson for replacement one-off parts. Can't remember who typed that now but hopefully he'll chime in...

 

Ah ok no worries. I’ll emailnthem now and find out. Thanks

 

Its in the first section of post 1 titled "maintenance" bud. Mosey on over to their website, or if you don't see it, shoot them an email or call them, they'll hook you up.

Post 1 is the Bible of this thread my man.
