We just installed a dual 450 l/hr in-tank pump system from Lingenfelter into our TVS2650 Camaro. It just dropped right in (with a bit of additional wiring) and has a -8AN pump output. Got it strapped to the dyno tonight and hope to make pulls tomorrow to see if it's up to the task of 1100+ RWHP.
Its the same low pressure fuel system that Lingenfelter is using in their 800RWHP ZL1 and I believe that it is available from them now.
I'll update again after some dyno pulls.
