are there any benefits to having a reverse split cam? for an all motor car with most bolt-ons and at the most STG 1 heads would they put out more power than a cam with same duration and same lift.

230/224 .575/.563 111 LSA vs. TR224 .563/.563 112 LSA

Thanks for any help that yall can give me

With the TR230 you would get a little more top end than the TR224. Plus you would be spinning the TR230 a little bit more. IMO the TR230 is a good cam for the performance you can get out of stock heads, if the heads arent stock then you should go bigger.

 

Personally, I think reverse splits aren't very useful in a performance aspect. They kinda give off a "stock down low", "hot-rod up top" feel. For me, I want a hot-rod all the way around cam, so I always stay with a foward split.

 

Me car runs pretty good with a TR 230/224 @ 3500+ lbs race weight.

But your low-end (below 5k)looks just like a 224/224. Never said it couldn't be good in a performance aspect, but if you'd like more, try the split the other way. 230/236.

 

wether you run a standard or reverse split camshaft really depends on how well your heads flow.

People have shown that TEA heads do better with single pattern and reverse splits than they do with traditional split cams. This is attributed to how efficient our exhaust ports are. Different heads need different cams to obtain that ideal relationship of intake and exhaust flow.

 

Very true. Intake to exaust relation is a critical part of picking a camshaft. If you have a very efficent exaust port, I would say semetrical or maybe 2 degrees of foward split would be plenty. There aren't many situations in which I would venture to a 6 degree reverse split. Seems like it would hender to much flow and somewhat restrict the exaust.
