Two weeks ago I brought the Z for some fine tuning at Z Car Garage, only to find out that the car only dynoed at 155whp/190wtq. This was VERY disappointing, considering the engine was well over $5k and was initially dynoed at about 300hp to the flywheel.
I finally had the time to bring the Fairlady Z up to Antioch for Dave Rebello (Rebello Racing) to take a look at it. He spent the better part of two days fine tuning the car. Dave found that the accelerator pumps were not working correctly, a heatshield bolt bent the first carburetor's throttle plate, and the valves were adjusted to factory spec by a previous shop. This all made sense of why my Z car was not pulling the numbers it had initially done on the engine stand.
After the Z car was finished, I brought it back to Rob @ Z Car Garage today. HUWALA! Look at the comparison! The car pulls about 240whp/221wtq, very much mimicing what it had done a year ago on Rebello's engine stand. I am very happy with the results, and SO ready to bring it up for the Z Car Garage Z Corral at the Monterey Historics this weekend. There is a small exhaust leak between the header and mid-pipe, but should be remedied before this weekend.
