Just to add if you do some research you will find that low LSA cams also have a more peaky TQ curve... They come on real quick but fall off quickly... The lower LSA has a direct relationship to the overlap, when defines where the cam is efficient... lower (more negative) overlap moves the efficiency down in rpm, the higher (more positive) moves the efficiency upwards meaning you spin it higher.... Cam selection comes down to overlap and DCR... The duration, lobes, LSA and ICL all contribute and need to adjusted proportionally... Believe it or not cam selection is a science... I am no expert but i do pick out my own...

 

Do you run a two piece timing cover? I think I am gonna get one, do you have any leaking issues?
I' m right at 11 to 1 comp also. I find that if you run a bit more duration with a short over lap it all comes together.... I don't spec my cams but I read alot of theory.

 

i have read displacement is linked to overlap more than compression... compression always helps!

 

what roll does weight play in all of this ? i also try to do a lot of reaserch on cam's but no were neer as knowledgeable as i wish i was .....

 

If it were up to me I would run mine on a 112 or lower , but I need to have at least -4* overlap to pass smog so I am stuck with a minumum of 114 usually...not to mention the choppy idle you get from a lower lsa.....

 

you must know people man if not pm meeeeee man i got you ....lol

 

I appreciate that..and may take you up on it...You are probably only a few hours north of me...

-I have a guy that will look the other way on the visual, but needs it to actually pass

 

TSP 220 581 110
I like it alot i dont really care to spin it past 6500 and it hits hard from 3400-6200.

The idle was a little tricky to get tuned even after the throttle body was diagnosed as dirty, even now it could use some fine tuning ecspecially now that its summer and the ac is on it can dip down sometimes but its not that bothersome i just havent had a retune yet.

Speedo video yesterday... Inlet air temps were about 135 so it was running like ****. I just got done stuck in traffic for 30 minutes with AC on


Also i was getting back on the freeway and i let out is why it shifted a little early from 2nd to third. Lol as soon as i came over the the little hill of the on ramp there sat a tarrant county sherrif Lol and YES it's still slow as f**k!!

 

I have a 222/226 56/598 111+2 lsa going on my 5.3 tom morning. 10.5 compression .. it was speced by patrick im happy with the specs .. ill have idle videos tomorrow if werything goes well..

 

This should be made into a sticky if something already hasnt been made like this.
