I like to think the 4.0L Aurora V8 is comparable to the GXP, based on those number ( and no I havent dynoed my car) I could probably match it if not exceed it.
Interesting... :?

I bet Canadian snow ba.... er white Aurora can really scoot now and would probably give a stock GXP a run for it'* money.

GM reads this Forum quite regularly
I've spied some obvious IP addresses over the last year or more. This is good info for them, and Scott Cook is no stranger to GM. They know very well who he is, and out of all of us, he has the chance to actually have some influence on them.

I've been thinking about the breakin theory here. It has merit. I bet it would dyno closer to advertised numbers with about 30k on the ticker. My 98Z71 did. With no mods until that point.

We had forced air directly to the intake and a larger high CFM fan to take away engine heat. It wasnt a 7,000 fan pumping 75 mph winds, but it was adequate. I would suspect more the calculations the dyno used on ambient temp and moisture to calculate HP before I did wind speed although Scott says the GXP feels slow on the street and he can't get his tires to spin even standing on it from a dig.
The autotap log we did on his car showed him getting knock, im some cases quite a bit. He may have some sort of restriction in the engine due to an engine built on a Monday or Friday (not quite right) or it may have just been the heat of the day (cars were regestering about 90F) but somethign was off on it.

Marlon, Scott Cook and the Intense crew know more about performance and dyno'* than any of us would ever hope to learn in 5 lifetimes. They cut their teeth on it, and everything they do is based on hard facts and true, definable numbers.
They have a very good dyno setup, and use it correctly. Including with air
