What's your take on these dyno numbers?

All good questions

Skip the green belt. Go with a normal black style. I'm going to assume you don't have an aftermarket boost gauge. Were you there when the car was dynoed?

I was not there. Damn day job... I do not have an aftermarket boost gauge - although the guy said it made 15lbs... But maybe that was just at the start.

Let me see if he can produce a boost chart as well.

Thanks @2003RedfireVert - that's great to know.

Damn work getting in the way of fun.

Look around the blower pulley for black dust. That will tell you if it's slipping. But watching/recording a boost gauge helps a lot.

Something is not right. And that graph looks terrible.


This graph is from 07’ on a mustang dyno. 413/460. Car had 2.93” upper, 4lb lower. Same setup on a dyno jet dyno made 457/507.

Here is mine with a stock Eaton, 2.8 pulley, dyno jet for another comparison. 471,484

Agreed - your numbers are similar to what I put down on a mustang dyno after I did my mods.

I wonder if the car wasn't strapped down well? It looks like a diesel graph.

I would take it somewhere else to compare. But as long as it's running good and the tune is in check you should be ok.
