i \<3 DSM’s. it wasnt the tuning that was bad, its the fact he lost fuel pressure. I bet the car would have been fine all day long if that fuel pressure didnt drop. ---

> [@tnick24](#): > > it wasnt the tuning that was bad, its the fact he lost fuel pressure. I bet the car would have been fine all day long if that fuel pressure didnt drop. Are you sure? I mean that dip in the air/fuel graph followed by a steady lean a/f climb is not good for any turbo car. He was using the cobbled together mess known as megasquirt and some awesome toonerz…what do you expect? Just because one of the guys in the video says the “fuel pressure dropped” doesn’t mean that it really did drop. Its like saying bad spark plugs when you need to replace a piston with blown ring lands. Its an easy way out of a bad tune. Then again who cares the kid just wanted to see what his car could do… he seen it make 35psi and he also seen himself get burned on a blown rod. ---

It probably saw a tad too much detonation when the AF leaned out and the dramatic increase in cylinder pressure compromised the connecting rods. Those were rated for 350 whp. [Previous page](https://forums.speedlife.net/t/how-good-is-the-bottom-end-in-a-dsm/6925.md?page=1)
