Compression
You can load them down pretty low. You just have to have a reason to do it.
OK. IDK a whole lot about these machines. A lot of times and even in here once in a blue moon, someone asks the question, and I don’t see much of a reason to be concerned with power output at 1,00-1,500 when your cam is something like 250/260+@050. No one is putting a cam like that in there car with 2/76 gears riding on 28” tires looking for street manors in the city. Unless you’re crazy? Maybe driving your top end machine built for something like a 1/2 mile oval track? But why would anyone want to build that for driving in rush hour in the city?
Yea, I know it happens….
Loading the dyno that low to know how much power it has at 1,000-1,500 with large street cams, small or big race cams seems silly to me.
Is there a reason?
Have you done this?
Why? For what purpose is that t needed to be loaded and tested @ such a low rpm with cams of 250@050 and greater?
What customer needs to know this and for what?
As I said, I only have been told what I said. I’m not arguing with them or you over it. I’d just like to know.
Have you loaded the dyno @ WOT with a 250*@050 cam down to 1,000 rpm?
Every dyno show I see where they start at 3 or 5k because 'lower doesn't matter' seems to stem from a lack of desire to tune down there. They just throw more converter at it as it's dripping fuel from the pipes.
I’ve been told it’s also related to the cam size and function of the build. If I have an engine with a sizable cam where any meaningful power comes in at 3500/4500, what’s the point of knowing what’s at 1K/1500/2000 rpm.
I’ll just live with what it makes and use the right converter coupled with the gearing and tire size to out out along. After all, the engine means business not at the low rpm’s but where it picks up.
This is what I noted on the shows and what I’d be after.
