TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Hmm, thats not too bad.

 

Good looking out as well.

 

Does anyone know if you have to do anything to the crank pulley like the old ones? Something about sleeving it so it doesn’t leak I think, or has this been addressed by NST?

 

What benifits does this product achieve? Downfalls?

 

Lighter. Reduced mass, quicker. That and they look cool. Maybe they come with a sticker. That always adds hp.

 

On another note, will my new 70mm TB help lean my afr’s at all? Haven’t installed yet.

 

I wish I could tell you. My gauges weren't installed when I went 76mm. Truck runs better than ever. I dont think it changed much if at all.

 

Did you port the opening on the s/c to match the 76mm tb

 

No. But I will soon. I live in an apartment and wrenching is frowned upon. @Roostfactor did. If you need tips he's the guy.

 

Possibly a little at wot. Do it and let us know.

 

Well from the research I can find. It looks like that if the RatioTek kit fixes the problems associated with the auto trans and the super charger, then the TransGo kit will do that too, plus adds a few extra items that really may or may not be needed. I can say that I really do like the way the truck shifts now. It is firm, but not harsh. My trans temps didn't go down much at all if any after the kit, but they sure have now after the 4.88's, like way down. Anyone else used the TransGo shift kit on their A750E?

 

I did. I noticed better throttle response and more top end.

 

Awesome. I was doing the swap to see if I could get better throttle response. I figured any other gains would be minimal.

 

I ported the sc inlet to match the stock tb before I ever installed the sc.
Then port matched it again (only slightly) to match the URD 76mm tb adapter.beforeafter

Someone can get a cheap gauge pod

 

Damn i just ordered mine. Also back ordered 4 weeks...

 

There is enough material to shave down and actually match 76mm? Did you use a dremel?

 

No but there is enough to match the URD tb adapter.
Yessir. Mr.Dremel in effect.

 

I did a great write up that I’ve past on to a few people on what you have to do to slightly modify the gauge pod once you get it. If you want it let me know

 

The Transgo kit is not meant to increase shift speed and adjust line pressure like the RatioTek one does. The Transgo simply improves on the valve body with what is already there and reduces a lot of the known complaints which the A750E is known for.

Taken directly from the TransGo site.

"Addresses Shuttle, Bind-up or Flair on 2-3 Shift, Slips with throttle in 3rd and/or 4th, TCC Codes & Rough kickdown at Highway Speeds due to slow TCC release. Improves and restores correct drivability with added durability."

Nowhere there does it say it improves upshifting or downshifting speed to better address the sluggishly soft shifting this transmission is known for, which does not enjoy getting abused by an increase in power added by supercharger modifications.
