Exciting news for us. HolleyECU is in and working properly. New tune done by Arizona Speed and Marine is perfect, Flawless acceleration, Decel, etc.
We did several data log runs using our 28P Bravo 1 (UNDERPROPPED), we found some amazing news with these runs and we also learned a bunch.

1. we are only running at best 2.9lbs of boost, Compressor speed is extremely low,
2. we are running a pulley sized that in a stock 496 Mag HO would produce about 5lbs (4inch pulley)
3. We are moving to 7lbs of boost with new pulley (3.4 inch) We expect through the data logs that we should hit that target very easily.
4. Gates belts makes a new belt called their RPM series made just for these blowers and are less likely to slip or stretch.
5. Because of the ported heads great head flow and large cam it changes pulley requirements.......the 5lb pulley in this case make a best of 2.9 lbs of boost.

We are going to test up 7-8lbs on pump gas. We are also going to install Cog drive on our second procharger to test up to 9-12lbs with race fuel. It appears when you build a blower motor you can have great boost with custom low compression pistons like we have. We are very excited to see the power numbers/speed increase, I would like to see 95+
