another update.
You can all look at
www.hiperformancesolutions.com for the best designed intake I've seen for our applications. HUGE plenum, medium runner length, removable bottom cover, extrude honeable, port-able. Best part is the runner towers can be adorned with a fogger nozzle and appropriate bracketry and you'll have a killer totally hidden nitrous system. If you're running boost, you can shoot a charge of water&methanol into the lower plenum and cool the boost when you crank it up for drag day.
The guy in charge of the design and production of intakes for the 4.6 and 5.4 is heading up to Chi-Town shortly to go over some tooling details for the 4.6 unit. That means the 4.6 intake is nearing readiness to go full production. As soon as that's in production, the lights are green to stretch it for the 5.4 which will take a good bit less time since the design is effectively the same with some tweaks to keep the power up at the higher end.
I'll be putting the 4.6 intake on my 4.6 and then on my 5.4 with plates, then I'll get a 5.4 intake and sell one of you hippies my 4.6 intake on the cheap.
