LSA...what does it mean for power and idle?
LSA...what does it mean for power and idle? Ok guys im starting to figure out what kind of cam i want for my application. I have been looking at many different cams and I am ready to decide on one but im not sure i understand what LSA means in terms of power and idle. 
Am i correct when i say that say a cam with a 112 LSA will have a choppier idle than the same a cam with a 114 LSA?
And if its a 114 LSA that means that the power band will be slightly lower than a cam with a 112 LSA givin that they are the same cam?
I want a noticeable choppy idle but i also want the power band to be lower...being that i dont really push the car past 6k rpms( just afraid bad things will happen...i know im a puss)
I am lookin at a TSP 228R or a 228 from virginia speed? Any others i will take into consideration as well
Please set me straight...and sorry for the noob questions!!!!

if you doint want to go higher than 6000 a 224 cam is all you need its a good cam many have hit the 11's in the 1/4 with that cam and suporting mods.
yes a 112 lsa is going to be more choppy and a 114 lsa is going to be more streetable but it will also depend your exhaust in how it sounds too. I have the TR 224 and it sound great to me I have a cutout and its as lound as you can ever want it to be.
a 228 cam is a decent cam and I'm shure you looked at some dyno charts right?

yea i have looked at some dyno charts to see what kind of power has been made and the 228 from virginia speed has made the kind of power that im lookin for...i have 4.10 as you can see in my sig. so i think that would help out if i got a 112 LSA. How much difference in RPMs would i see for the power band between the 112 and the 114
i plan on getting new springs obviously and new pushrods as well. I would be fine pushing it to 6500 rpms as long as it would be safe on the motor which has 52k on her.
im runing a 228R cam on a 112lsa and i could not be happier. The lower the LSA the lower its peak power will be at. say 112 peaks at 6200 while a 114 peaks at 6400 but power comes in later
Are you sure I thought it was the other way around. my ms4 runs to 7k its on 111lsa. I thought a 114 was a flatter cam across the powerband and the lower lsa peaked higher.

yeah get springs rods and retainers for shure I now it sound kinda lame but if you want a more choppy idle get the 112 but the 114 will be fine you will know that it has a cam in it for shure. Its just more of the 114 is just more streetable Its not much of a diffrence on the curve, unless you plan on doing some serious racing later I would just look at it this way 112=Choppy 114=little choppy and more streetable haha.

What r u runnin a 112 or a 114?
i thought i could reuse my stock retainers but how much do they run?
while we are at it haha i also have a another quesiton at timing...I am lookin at the TSP 228R which doesnt have any advance ground into it. So does that mean i would want to have it installed at like 4 degree advanced to get a smoother earlier power curve? I know a lot of cam have it ground in

If its 0 you just basicly line it up with the marks that all I wouldent bother with advance if your doing the install it will just make it that much more of a pain.
I have the 114 lsa and it sounds good to me I have a cutout so if I want it loud its open, and I like the idle I'm shure I'd like it if it was choppy too.
and like said above just get the whole kit springs rods retainers and gaskets its not that much more for some inshurance for the future.

the cam im thinking about goin with is the TSP 228R .588/.588 112LSA and then when gets installed having them advance it 4 degree to have a slightly lower power band. I was also gonna go with 7.425 pushrods to quiet the valvetrain along with new springs maybe the 918s...sound like a good combo?
