I posted this at dyno comparisons,

https://ls1tech.com/forums/dynamometer-results-comparisons/648131-help-me-pick-my-next-cam.html

Figured I'd post it here also to get more feedback. This was my last post.



"Ok, I think I got it narrowed down to 232/236 .595/.598 but I'm still not sure about what lsa to run it on.

Can somebody tell me what would be the difference in hp/trq, driveability, tuning between running it on a 110 lsa, 112lsa, or 112+2 lsa???

BTW, my tuner Cartek is telling me to run it on a 116lsa for better driveability, ease of tunning, and a broader powerband. It does make sense that I'll have less overlap, but in turn the IVC is also happening later."

I would prob go with like a 112 a 116 is a pretty wide LSA. The 112 will get you the power quicker so more torque for off the line. The 116 will be a sleeper cam almost, bc the idle will be fairly choppy but not too much. The 112 will give you the nice cuttin up sound.
Hope this helps.

I'm not going with the 116. I'm trying to decide between the 110, 112, and the 112+2.

I woul then maybe go with the 111 or 112 and if your wanting to advance it 2 degrees you can get an adjustable timing chain and you can advance or retard the valve timing that way. With N/A cars more overlap is usually good, for boosted car more overlap is bad. So your setup depends on what you need.

LSA does have an effect on driveability, but taking the same lift and duration, the cam with the less LSA will make more power down low and ultimately do a better time in the 1/4, but you sacrifice gas milage and may have more of a dyno tuning issue. As long as the cam doesnt go 24X or more duration that shouldnt be an issue at all. Id get 110 or 112 grind, I wouldnt even consider anything more then 112.

I run a 112 . The 110 can produce more power but it will fall off faster, be more peaky where the 116 will produce a broad torque curve and slightly less power. The 110 will be more explosive. This is where the driveability things comes in. Short and choppy versus long and smooth. 112 is a good compromise

Would a 112+2 be harder to tune compared to the 112?

Do a 112+4 or a 112 and advance the cam 4 degrees on install.

I guess I should have put the +4 in there.

sorry for the dumb questions, but is there any difference between grinding the +4 into the cam or advancing when installing the cam?

Also, what's the difference between running 112+2 and 112+4?

Most of my cam exp is dealing with LT1 grinds which never, ever deal with cams ground advanced or retarted. Speaking pure LSA, the wider the sep, the easier it should be since there is less overlapping of cam events.
