So according to their testing about their modded vhr intakme manifold is a 9whp gain for 295$ + 220$ core charge if you dont return yours ....
So I wasnt to far off by asking 525 for a complete modified intake manifold.
edit ; oups... I thought on their website they did the stock VHR Intake manifold vs their modded one.. but it was the unmodified HR vs their modded one..
I would love to see an actual test with a modified HR vs their VHR ... I would still stand if about an HR modified could be superior 3500-7000whp
