Stroker specific cams?
And unless you are NHRA class racing, who gives a rip about "maximum horsepower". 9 times out of 10 you sacrifice horsepower for torque at a certain RPM. You can build a big power engine and put it in a car with the wrong converter, rear gear, or tire size and it is almost worthless. THere again, on the dragstrip it's different. On the street it can be a waste.
Who is talking about max HP. That's something that's being made up.
Look at nm9's post. There are times when killing low end power is the goal. Traction limited cars, most of the circle jerk guys at the local level think they are chassis gurus but an average engine builder can build enough power that the heroes can't make them hook on the best days.
LSA isn't about peak HP. I'm talking about under the curve power, which is what the street driving guys sqeal about constantly.
Using LSA to change idle is crazy. In fact, I'll say it's stupid. Here's why.
You must reduce duration to open the LSA up, otherwise the engine will hold power past peak way too long, and you give up a TON in the middle and lower middle of the power curve doing that.
If some can dude tells me a cam that has been cut on a 110 LSA has a rough idle I just hang up the phone and move on.
I've posted this before and it's still true today.
110 is the de facto LSA becuse Comp wanted it that way. Buying as many cores as they do, the 110 will fit on every core without issues. They can pull the cores out that will go down to 104 and up to 114 and use them when they need.
That's the FACT. It's not a speed secret. Jamora from Isky has written about this. So it's not like it's hidden.
To compromise valve timing events to get the LSA you want is crazy. Just crazy.
The guys who don't or can't test always pull out the max HP card. It's because you don't know what you are losing.
IDGAF what engine or class we are talking about, there will be only a few different timing event sets that will work. That depends on the agressiveness of the lobe, intended use, traction potential (or lack of it), induction and maybe two other things. I'm not considering overall air flow or any of that.
Once you have that information, you'll see that any deviation from the required duration to achieve PEAK power at the RPM required will kill power everywhere if you manipulate the LSA to affect characteristics that should be left alone.
That's wasting power. Not peak power either.
