So, after 12 months of work the 240Z finally gets some dyno time to see if all the work pays off! Previously the L28 stroker running round top Hitachi SUs made 170rwhp (dyno sheet below).
I’ve linked the youtube video of the dyno runs and a test of the launch control at the end of the post.
What change did the modifications make? I positive one!
A peak power of 201.6rwhp @ 6000rpm was recorded. See dyno sheet below.
In comparison to the 2017, the curves are a little flatter but higher which is good. The car feels like it could pull for days when the cam ‘kicks in’.
Not bad for the standard Hitachi round top SUs! Makes you rethink about the ‘need’ for triple carbs to make power?
