Default LT2 HPFP options

Hi all, we have a C8 that we've done a procharger kit on with upgraded LPFP, but the HPFP can't keep up. In all my research I can't seem to find any definitive information on the subject. It doesn't seem like anyone does a drop in HPFP upgrade for the LT2. Seems a number of people fit LT4 pumps, but according to some forum posts, they don't actually flow any more than the LT2 anyway. But I haven't seen any test bench data from either pump, so there's really no telling.

We have explored the option of a cam upgrade as we normally do on LT4's etc, but wanted to give the customer all available options, including retaining a standard cam and just upgrading the fuel system if it's an option. I don't know if there's a port injection kit, but I think we're trying to avoid the added complexity of another complete standalone system in the car.

Any advice on the subject would be greatly appreciated.

Cheers.

You should be able to run a Goliath or LPE Big Bore. Contact XDI and see what they say.
