TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Thanks. I'm going to give the Lucas stuff a shot and see how it goes for me. BOOSTane is available online and I might try that later, but measuring part bottles and a little more money per tank are the downsides.

Good to know. Sounds like if the octane boost doesn't work out I have a good backup plan

 

Anyone running the Steeda belt tensioner for the S/C? Did you have to do any mods to make it fit properly? Does the OEM size pulley fit on the Steeda unit?

 

Selling the SCOL double row upper idlers. I was parts hoarding but someone might be able to use them now and enjoy free shipping. https://www.tacomaworld.com/threads...n-buy-sell-thread.664742/page-3#post-27622084

 

no. i bought it but the look of stress cracks in the factory unit wigged me out and i returned it.

 

Who does the porting? I’m going to install my supercharger soon but could wait if porting would now would set me up well for going to small pulleys next year

 

I thought nobody ported our 2nd gen Tacoma blowers… 1st gen for the 1st gen (gray version that bolted togeher), yes.

 

I believe scol will port the 2nd gen blower

 

Steigemeier ports our 2nd gens.

 

when I was in Baja down a Stretch of no premium I had a to run a few tanks of 87. I had bought a bunch of octane booster and it seemed to run okay. I did take it easy.

Maybe you could tune it to run on 87 wouldn’t be as nice but may extend it some. You could always flash back whenever.

 

ah, found more info.

But @Torspd ..I think it’s story time. What’s this about rolling backwards the first 10 feet of a race?

 

Got all excited after a good burnout. Rolled back, and forgot to shift it from reverse to 1st. Made for a good laugh. Lol

 

Hmmmm

 

I'm surprised they are able to get as much gain out of the blowers as they do. Supposedly Magnuson did a stellar job with making the blower flow as much as it possibly could on the MP90 models. Apparently there is/ was more room to open up.

 

Are you ported? I never finished that thread.

 

No I'm personally not, but I'm right at that 320-330 HP threshold, so another 35-52 HP would be well worth the trouble if it does indeed gain 10-15% extra power.

 

and no way for emmission tests to know about.

 

even better! Another thing to add to the list. Do folks feel the larger throttle body and port-matched spacer (modded) from URD is a good pairing?

 

I have a 70mm throttle body and spacer, if your interested pm me. I'm not going to use them.

 

Measure vacuum pre-TB and post-TB (Before rotors) and see what the pressure delta is at WOT. If you don't have any or it's not much, the TB isn't a restriction.

 

from the Tundra s/c world, it seems like the price/performance ratio isn't worth it for the larger throttle body. At least from anecdotal evidence from members. If you've done everything else than go ahead, but I'd save it for last on the list.
