TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Juan, is it your merge collector resonating? Your issue sounds very similar to what I experienced.

 

That very well sounds like where it could be when I say passenger side underneath. I bought the new cai to rule things out. I installed my longtubes and URD tcai at the same time so I couldn’t say I’ve had this before one or the other mod. What did you do to fix it!!!

 

My issue was with the Spec-U exhaust. Originally installed with the stock manifolds/cats it sounded amazing. No issues.

A year later installed the Spec-U headers. HORRIBLE resonance at similar RPM (can’t specifically remember now, maybe 2250-2750?) it sounded almost like a heat shield was rattling against the exhaust. Very loud, but was isolated to just a particular RPM widow. Did not seem to be affected by the amount of load on the engine. It could be induced free revving the truck.

I pinned it down to the merge collector in the Y-pipe. Had the wife rev the truck and I tracked down the origin. It was the Merge in the Y.

For whatever reason, the tuned frequency of the exhaust at that RPM with the headers caused the merge to resonate. I couldn’t get it to stop, so I sold the URD exhaust/y-pipe and went back to stock exhaust/y-pipe.

I’ve been happy since and no resonance. Probably not an option for you since you’re boosted, but I wonder if that’s your issue.

 

Sounds the same in terms of how it sounds and can do it at will without load being an issue. I gotta find a fix….

 

Good deduction.

 

So what can I do

 

Go back to stock and start over.

 

hold on to your old hose clamps. 3 of the 4 they sent me a few weeks ago were too small.

 

just got the hoses installed

 

How much HP does all that red give you, do you think? Like 25 extra?

 

i kinda think you're underestimating there bud.

 

Those red hoses do look great. Im gonna have to add those to the list now

 

Washed the truck and cleaned up the engine bay a little today. Also tracked down another alternator pulley thanks to Mightytacoman and that came in, so im going to give that another go next weekend

 

@BassAckwards what are you using to clean the engine bay???

 

Who wants to buy my super charger full kit? So I can change over to turbo? I want more power.

 

Just a wet towel to wipe things down

 

All the panties that are thrown at him, duh.

 

i have yet to find a decent engine cleaner. although I'm not looking very hard...

 

Same here, after every wash

 

So after a little more research on this, I found 2 vibrant resonators do the trick. How many people here have done this. @loginfailed
