The underlying concept for this system is that you can essentially get to the upper end of the stock engine limits without an IC which keeps the system simple, clean, and less expensive than an IC'ed system *for those cars that did not come with a SC*.

That said, I'll build a kit to mount to the S manifolds as well. However remember that the setup will all ready about max out the stock pistons w/o an IC. To add an IC and bump the boost up will push you further into that glass ceiling. So, adding an IC to the TVS system for Elise or NA Exige guys, in particular, would only really be a substantial benefit if you swapped the pistons for lower compression units and then go for a 300+ whp monster...

So, I can see an upgrade path for S/Cup owners here since they struggle with IC efficiencies so much, this would make it easier for those folks to get to the 275+whp figures...

Hope that adds some clarity...

Best,

Thanks for the clarification Phil, I agree that the stock pistons are def. maxed out around the 275 realm before needing to upgrade pistons for more durability. If you feel the stock pistons will hold with your kit, then I am game (reason being, I have the opportunity to upgrade to forged pistons, but that is a whole different ball game....compression, boost, tune, etc.) At this point, I am most concerned about reliability on the "glass engine."

Edit: I just read Rob's above post....so your pistons ARE upgraded?
