Why use a reverse split Cam?

Again based on past testing either of these cams could be either forward or reverse split and basically do the same as they are already doing. EVERY internet 'expert' knows the reverse split 'doesn't work' so we made this one a forward split. IMHO the exhaust opening point is probably the least sensitive parameter for a properly tuned header system on a street motor. Your mileage may vary, J/K .

Peak power is all that matters!

I've been really looking at this cam too, along with the MTI X1 cam. This thread has answered many of my questions! I see the graphs and all....like others said it doesn't make hardly any Hp/Tq difference from stock till the higher rpm's. Maybe i'm too greedy but I want a cam that makes a better low and mid Hp/Tq and still have good high Hp/Tq numbers. I'm looking for 400+ rwhp. I will get a tune!!
FYI...just looking now because I stilll need to get other mods like headers/ory and all the goodies to swap a cam....springs, pushrods...ect.

A little more power, but not much of nothing compared to a traditional split cam. Look at this graph comparing the TR224, the TR 227/224, and the TR 230/224. All of the graphs are the same until 5k or so. There's no reason not to gain low-end power when swapping cams. The reverse cams just hender the exaust to a point to where they can't move enough air, thus not making any more power that it's smaller counter parts.
Ok, if you don't give up any bottom end, pull pull more in high rpms, how is that a bad thing??? i will put together a little comparison b/w my stockish dyno and cam only dyno, give me some time...
You pick the right reverse split cam, and it'll make you happy....

Red = Borla, free mods, lid
Blue = Full bolt on
Black = TR230 on w/ 853s
All were tuned pulls, all were SAE #s, all were previous dynos of mine
Were the 853's not on the previous combos? Any advantage to them?

my friend has a custom grind i believe TSP did it and I also believe it was on XER lobes, its a 232/228 573/571 113, he never had it dynoed but it ran 11.2@120. I now have this cam sitting in my closet waiting to go in. To me its not about dyno #s its the e.t Love the reverse split!
Love the reverse split!
