Little lower than I would expect. But it may also be the high altitude.

Its my unrstanding that there is some kind of formula to calculate how much HP is lost per 1000' of altitude. I cant remember the figure per thousand ' though......anyone know??

Paul Workman · 04-02-2008

Considering the altitude, I'd say that is probably typical, all things considered.

I lived in Bailey CO (8500 feet) and I could tell a significant difference just between Denver (5280' amsl) and 8500', to say nothing of comparing my 95 LT1 coupe at 600'!

Altitude is a big concern for me and my plans to move to CO to live. But, I guess all things being relative, performance will remain the same, compared to other cars (except for turbo or SC cars!).

What kind of dyno was it?

04-02-2008

I hear that Dyno to other Dyno become different...

and also in which State you did that, as we know The altitude can affect too.

Since you live in Colorado, then due to reduction in atmospheric pressure attend to decreased partial pressure of oxygen,
then your engine HP normaly reduced.
