I will probably just see when the power curve ends, if its still making power at 7000-8000rpm with the GT47 I will let it eat. Obviously if its not making anymore power past 6500 its unnecessary. I was in contact with Nitto last week to purchase some ARP625 rod bolts, they said it would be a waste unless I'm seeing 10000rpm, Im currently running ARP2000 Bolts with a "0.250" gudgeon pin. I will relay the above to my head guy when the time comes, The oil pump should be more than capable supplying oil at these rev's same pump has seen 10000rpm on the dynomite car.
