I was browsing the Sean Hyland Site and came Across this dyno chart.
http://www.seanhylandmotorsport.com/dyno/dyn4.html

The chart shows a gradual climb in HP thru 600 hp. But when you look at the data posted below it jumps from 346 hp at 6800 rmp to 600.4 at 6900 rpm. Am I missing something ???

It looks like either the data is a mistake or was doctored....

I know there are big SHM fans here -I dont know SHM nor do I know much about Dyno's but I do know a little about charts and data. I am not trying to pick a fight I am just looking for possible explanations....

Superchip ( Retired ) , and 3m Panther Black nickel tint.

 

Graph looks correct, HP data in table doesn't look right...

To get HP data: TQ * RPM / 5252

Dyno's only measure TQ, HP is calculated.

And a quick check for a doctored dyno graph is to look at the 5252 rpm point, the TQ and HP number should be the same, i.e. the graphs will cross.
