Supertech Dual Spring Ti Retainer Kit

[theoptimist333]

anybody have any experience with these? They say it will help you be able to rev ur Tc up to 9,500 RPM with supporting mods. I was wondering if anyone could explain the supporting mods, or if they think this is bull, I would love to be able to rev up to 9500 in my scion. any help would be really appreciated.

heres the link to the site i found them on:

Those won't get you to 9,500 RPM, but if you do enough (new head, cams, injectors, engine management, etc.) and get your engine to go 9,500 RPM then those springs can handle it. Thats really all they are saying.

o ok. yeah i thought it sounded odd. that might be happening for me, but not for a good couple years lol.

This all assumes that your e-manage can successfully bypass the th Toyota imposed RPM limit. The Greddy Ultimate cannot bypass the factory Rev limiter, nor has it gotten around the speed limiter either.

Megasquirt can do both I believe.

But th megasquirt is a standalone. All standalones can do that. There are no piggybacks out there that can surpass Toyota's ECM.
