Avanti R3 Engine – Dyno Report!

• Initial dyno engine readings = 377 HP  – with the wrong carb.

• Second dyno output = 394 hp on 93 octane pump gas with modded Edelbrock AVS.

• 404 hp with 122 octane racing fuel.

Reading 7 lbs boost at manifold (after carb). Which means around 9 at the blower. 

Boost dropped off higher than 5700 rpm…..at the limit of impeller design speed.

We calculated 37,000 rpm at the impeller is too much  – just won’t produce boost above 35,000 rpm.
