Well, fuk. Got a dyno sheet from Seb. The car's doing the same thing.

It makes 20psi but only 630 hp. They're going to check tomorrow to see if there might be an exhaust restriction somewhere.

That should be easy to check. Drop the y-pipe and put it on the dyno with basically open headers.

That's what I'm asking them to do.

What about clutch slip, or would the dyno sheet reflect that? Here's the dyno sheet. The blue line is the blower that's currently on there, the red line is before it was modified?

The graph looks too good for clutch slip. When a clutch slips on the dyno you get react readings.

I was just doing some reading on that and they were saying you won't always get it by just looking at power and torque curves. You really need to calculate speed and gear ratio to be sure.

But, I sent an email to Seb asking him what he thinks. As you can tell, I'm really grasping at straws now
