Katech are cast aluminum, those appear to have machining marks - like they are billet. Maybe a newer version of Katech?

Nice build. Is that the Moroso Vacuum pump mounting bracket and pulley set up? I don't think those are Katech's but look really close in design.

Hey Steven, how are you guys controlling both DBW throttle bodies? I really need that if you can pass along some info. A PM would be fine if needed.

Thanks, Jason

I believe the pro efi allows the use of dual DBW TB. I know the Holley Dominator will allow it.

After first day of dyno pulls with 93 Octane pump gas I got 698rwhp with 22* of timing. I will be draining the tank monday morning and going with C16 so I can put some timing in it to see where the final numbers are at. I am shooting for 730rwhp, which for a Naturally Aspirated setup will be pretty incredible.

Yes, the twin throttle bodies are wired directly into the PROEFI box. The factory computer is still on board to control factory gauges. This car will have the luxury of having a switch the customer can hit to change from pump gas tune(for weekend cruising) to race gas tune (for the track).

Definitely the strongest Naturally Aspirated Corvette LMR has built to date! We have a GTO being assembled now with a very similar setup. Will be interesting to see those results with a little smaller cam shaft.

Will post up dyno videos and graphs beginning of next week.
