well for those that know me i have WAYYY too much prelude pride and love. so i want to make my big butt baby go all the way. I have my EG race chassis ready, and the motor might end up in that after this season.

thanks for all the support!

Awesome results! You must be very pleased . Do you ever plan on comparing the JUN cams to the Pro 3's on this new setup?

Also, when you take video, get some of the Tach and Speedometer...would like to see how fast those needles fly with that kind of power

An H series making that much? I call Preludes are slow and their tranies blow up in your face! J/K

People say all they want....but I love a good prelude/H-series build like this one.
