TRD supercharger: what do you guys think?

[Big Top GT]

Looks like a decent deal at $2000. What is this 7th injector though? I've seen various intake charge temperature reduction measures but I've never seen it done with an additional fuel injector.

How much boost can my 2002 Sport Edition 4Runner take before things start to break? How do things like the head gaskets, pistons, rods, crank, etc... hold up?

Thanks guys,
Alan

Definitely check out ttora.com or www.gadgetonline.com... all your questions will be answered there.

But... The S/C is a nice idea, but poorly executed. TRD did not work close enough with toyota to ensure that the ECU could handle the boost. Because of that, there is a lean condition that happens during WOT and upper RPM's that causes detonation and eventually cracked cylinder heads. TRD's solution was an extra injector - not to cool the charge, but to add additional fuel. URD USA (gadget) has done a ton of research and has a better solution, that generates about 40HP above and beyond the S/C's numbers. It's the ONLY way to go.

If you do install an S/C, please plan for $1K for fuel mods (TRD or URD) and an additional $1K+ for tranny mods...
