As I mentioned a few posts back, Jeff has the chassis at his trusted Dyno-Tuner's shop. Today he sent an IM telling me that the 2nd pull (with a mild tune) is now at 362 at the rear wheels. Since there is the theoretical 15% payment to the drive train, I guess it's somewhere around 415 @ the crank.
Part of me is saying to myself that I've reached my goal of 400-450, since I'm at 415 at the crank. But the other side of me is saying that my targets need to be measured at the Rear Wheels. If that's the case, to see 425 at the rear wheels, I'd need to be making somewhere around 475 at the crank. When we start getting in that range, I start to feel that it becomes wasted effort (and Dollars).
The tuner is going to hit it again tomorrow, to see what he can get, but I'm wondering if I really want to go much higher or not.
What does all the Dyno speak really mean? Crank Horse Power, Rear Wheel Horse Power, Ford Dyno, Chevy Dyno etc, etc, etc. Oh yeah, I've also heard that when you run a chevy engine on a dyno that typically runs Fords, you're actually looking at about another 15% above what the numbers show. If that's so, then I'm at about 478 @ the crank...
All I really know for sure, is that I don't really know what the engine is doing yet. Jeff said "It's gonna be SWEET!" So I just nod my head and smile.
One thing I can say with certainty, is that it's making me a little nervous to be running that brand new engine for all it's worth before it's ever even touched any asphalt... Especially when Jeff tells me about his collection of piston chunks that he'd like to show me when i come back up next time...
What are your thoughts? I'd really like to know.
