Very Intriguing!
Wouldn't you need to improve the exhaust flow as well to get these gains in power? Where are the Dyno's? Where is the Power made? Is this rear wheel HP or corrected crank HP? Wouldn't you need a new Map to see these gains? How Much????
Some guys are claiming high gains and then when you look at some 3rd party dyno curves there are big dips in the middle of the power band which sucks for normal driving but good on the track. I'm not even sure it's good for the track if the dip is at 5500 rpm. Looks like you guys do a lot of racing so I'd like to learn more as I'm contemplating some upgrades over the next couple years.
BTW I went to your web site and couldn't find anything on this product. I'm sure your web site doesn't represent the quality of your craft and your products but it is Vintage man. Please consider a new web designer.

PM per the above - info consists of the IPD posted gains. Site doesn't have but a few products and *I strongly prefer to have folks contact for info vs. reading/misreading etc from a one size fits all description*
PM/E-mail works best by far so we can provide a 1 to 1 level of service.

Is it really verified? Porsche went to huge lengths to get 26 more HP out of 997.1 3.8 with X51 package, which included Cylinder heads, intake, headers, ECU, etc...

There are absolutely no gains to be had with "plenum" products in theory or in practice. If you increase TB without modifying DME to account for the new cf in intake runners - it will learn/adapt and on N/A engines will shift the power-curve up somewhat - ie. loosing in torque/gaining top end. Personally I find these products highly offensive in terms of exploiting clueless customers.
