LSA Question

No. 90% of idle is tuning. Your timing curve and carb tuning.

You know how I know that? Because Jim at Racer Brown called me out on my tuning. So, I went and figured it out. And he was dead right. My cam is [email protected] on a 105 and it was in at 105 and it will idle down to 750 all day long. I don’t let it do it, but it can.

Rather than reading up on cam timing, maybe, just maybe if you ask him nice (I’d ask but he may not do it for me lol) @Hysteric may be able to post some links to what Shrinker wrote about carb tuning. And maybe some stuff Tuner wrote about it.

And maybe, if we ask nice, @Mattax will post some links to where ever he gets his information on ignition timing and all that.


Thats where I’d start. Because if you can’t tune or can’t learn it or don’t want to learn it or maybe you don’t want to pay to have it done then that right there is a big clue about what to do about cam timing.

You‘d be surprised how fruitless your effort will be worrying about mid range torque and the like.

Pick your compression, cam it accordingly and tune it up. Worrying about made up **** like “mid range torque” and “throttle response” will drive you mad because none of what you are looking at affects those things.

That stuff falls under the category of “drivability” and very few of the good drivers I know are even capable of taking a car out, evaluating what’s happening and then being able to explain it so it can be tuned.

That’s why if I don’t drive it I don’t tune it any more. It’s too damn hard to try and tune around what other people say, let alone the things they do even after they are told not to.
204° @0.050" lift on a 108°LSA cam is not much more than stock. An "RV" cam. It will likely benefit with some minor adjustment to the tune, but even the stock cam may benefit with the additional TLC of a tune.
