[QUOTE="Robert M, post: 15995361, member: 9628"] I have never heard any claims of hp gains from the BIGUN I/C, even from KB, but I do remember reading Van's thread. I think the same could be said for an owner installing a FRPP 2013 I/C in their 2008, better air flow below the blower, but minimal (if anything) shown on a chassis dyno. The gain is a reduction in air flow restriction between the outlet of the blower and the intake ports of the cylinder heads. If there are a couple of additional cooling tube rows on the BIGUN for additional heat removal as the hot compressed air flows through the I/C, that is a benefit also, but like a larger H/E, there are no quotable numbers shown at the rear wheels but instead the system stays cooler with minimal to no heat soak issues. <<<That is a large benefit to a GT500 owner..........but again, not a hp gain/benefit. Ford SVT Engineers increased the I/C CFM flow rate from the original 2007-2012 Eaton S/C to the larger 2013/14 TVS. At what point is an even larger I/C benefit realized? 2.8KB, 2.9 Whipple? or 3.2KB, 3.4 Whipple? 3.6KB? At some point, that 2013 I/C that was originally designed for the TVS becomes a restriction and more I/C CFM is needed to maximize the flow efficiency and minimize the flow restriction through the rpm range.
