TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

It was "insurance". I was testing it out and didn't want belt slip. Plus it looked solid and sold me when @BillDaCat8 fabbed his but IIRC he was using a stock tensioner at the time. I like adding shiny parts hah. Probably read into your guy's early posts and jumped the gun as I was still building my setup. I didn't know how tight the belt should have been but 2.7 with the Roush seems like a sweet spot for me and everyone else running similar. That Steeda billet sounds even better but no more problems ATM so I'm just going to shuddup

 

yah I hear ya. I was almost going to do it just like you and add the wrap but held off. I only have a 2.8 but was going to go down to a 2.5 but may drop it down to a 2.7 but would have it without the wrap mod but do have the RPM belt. the green one for me cut fine but started to frey and had almost skipped off the S/C Crank pulley but caught it in time.

 

it won’t be 5 like mine.

 

If you or @XPOTRPR want to test out the wrap mod, you can borrow mine before you shell out a couple bucks and spend the time cutting one down. For the low low cost of shipping lol.

 

600 diagnose. 6k for heads 11k+ for a used motor swap. gonna be a heavy mod year....in interest.

 

ill keep that in mind.

 

That’s terrible. I’ve spent about 9k on two engine replacements. And that’s cuz of adding new parts that did t have anything to do with the engine.

 

thats a good deal when you dont have tools, time, or knowledge to do it correct. after getting screwed on a cam install this is par. shop was really cool. if my kelford cams arent toast they will make them go in.

 

Your cams are in the current motor you mean and you may or may not be replacing a cylinder head or two???

 

Rob is correct. I was trying to say that I’m running the “original” TRD tensioner pulley that came in the blower kit.

When I went to the Roush tensioner, IIRC, I flipped that pulley to get the alignment better with the belt. It does ride on the edge, but, the belt is fully supported.

As for the RPM belt, I’m a big fan. It still looks good after 10k miles or so. It’s said to be less forgiving and therefore harder on bearings and such. To quote Mr. Skywalker, “I am not afraid”. The tensioner is referred to as a “dynamic tensioner” for a reason.

geez. Star Wars quotes? Maybe I shouldn’t post while I’m having my morning double espresso eh?

 

You know I'm about it..

 

Just an update, Reached out to SCOL regarding the 2x 10MM studs. They have them for 21.95 a piece and can sell them individually. Ordering a pair now.

 

correct. cams are in. its either both heads or full motor replacement. ill know friday pm.

 

Doh! I hope it's a simpler fix. Sending a little prayer.

 

Remind me - was the install bad or just overpriced install in your opinion?

I still have my gears sitting here waiting for me to tear into the engine.

 

ill know more friday but it ran like a banshee before the cams went in. now stuff sounds not good at all.

 

Stock valve springs?

 

no. considerably stiffer.

 

NOT MINE - New OEM short block in Austin. See thread for shipping damage that needs to be fixed.
