Some New Parts
Monday, May 3, 2010 at 7:02AM I made it down to the race shop in Pattaya yesterday. The work is more-or-less complete. Just the unavailability of a 1/16NPT tap is keeping the thing from being 100% ready for the dyno three days from now. The motor starts immediately, but still revs to 2500 at idle . . . . we determined that it is because we used a thicker head gasket which is making the intake manifold 'ride to one side' when it is installed, uncovering the intake ports on the opposite side and allowing air in.
The TB adapter was welded on and then hand blended on the inside for a smooth transition.
The working end of the new, high quality 80mm Throttle Body (TB).
The engine bay is complete. Now . . . I need to find a vacuum leak and dyno tune it.
Blended to the intake manifold . . . a little gasket trimming needed.
In case I need to laugh at the drag strip. But really . . . . some events here require you to qualify at a faster e.t. than you would want to race at every round. A little 70hp shot of "dry" NOS will help. I will dial in the fuel enrichment on the dyno. I have used a "NOS Safety Kit" - an extra solenoid near the bottle to make sure there is no NOS leakage and to take the pressure off the front solenoid.
