TRD Supercharger PSI

I was looking into the TRD supercharger and saw that it will get me about 50 more hp at 6psi. If i change the pully can I get more power out of it. If so what pull should i get and what is the limit for the supercharger and the engine.

 

Have you tried looking for existing threads?

In short- yes, you can run a smaller pully. Look up URD. HOWEVER (and this is a big however), even at 6 psi you need to be considering additional mods to run the SC. Plugs, thermostat, injectors, fuel pump, and some sort of additional fuel injector. Even then to get to "the limit" you need a stand alone ECU to drive all that.

You need to sell your truck and get something else if you want speed. I don't know how many different times/ways this community can tell you that before it sinks in. The SC and mods alone are in the $5k range, I think the standalone ecus are in the same.

 

If you want power out of the 3.4 you have to go with a turbo because you can get a lot more boost,
Supercharger is limited to the amount of boost so limited to power.

Your stock 3.4 is probably around 150hp at the rear wheel,
A maxed supercharger is 300ish rear wheel depending on elevation = -+ boost
A maxed turbo is 400ish rear wheel.

it’s an expensive road regardless and a rabbit hole.

if you want speed a Tacoma is not the road you want

there are plenty of threads on this subject if you look
