I was wondering if there is anyone out there that makes more agressive pulleys etc. to get more boost out of the TRD supercharger? I know TRD knows best... but, there should be times where you want to run a little more oomph... thanks a bunch!

 

I'm not sure myself, but some others on here might be able to point you in the right direction.

I'd be careful with how much boost you end up giving it. Blown gaskets, cracked heads or broken valves may be a result of a little too much oomph. :eek:

 

Course... but you have to figure... if toyota is going to make a supercharger and still keep the car under warrenty... you know they have to be keeping the boost at modest levels. I'm not talking about boosting the hell out of it... i know it wasn't designed for the extra load, just talking about 3psi or so. I'm relitively new to the n/a to forced induction though. 3psi could mean death... (I'm just used to my last car that could run 18psi all day long). Thanks again!

 

I'm pretty sure that elp makes a smaller pulley. Thats what I did on my GTP, stock is like a 3.8", dropped it to a 3.0", and added a Gator back belt. Gains about 30-40 hp.

 

That might be a little much...
the GTP is designed for the boost. on my old car you could achieve 53hp +/- with an extra 8psi... Thats more than doubling the boost. Without moding internals... I don't think that would fly... If only the I-6 from the supra wasn't used in the Runners
