first off, im not saying reverse split cams are the best cams..of course not. i went with the reverse split cam because they seemed to make better under the curve than a traditional split cam. especially my car being a street car.
go do a search on TR230 everybody and i mean everybody that has ran that cam has loved its under the curve which is what i wanted especially for an off the shelf cam thats already a proven cam. no disappointments. ive seen more threads of guys saying they lacked under the curve performance with there traditional split than those that hated there reverse split.

But how would YOU recognize their expertise?
And, please tell me why you are making fun of TXZ28LS1? (in your sig)
Why would a reverse split cam not be good and efficient on a 100 shot? Please give me the Tech reason (s).
Tech reasons a typical reverse split won't work with nitrous.. EVO is too late, duration is not long enough, incoming air charge will be diluted by unescaped exhaust gasses.. like I said in a previous post.. when using nitrous, trade unusable torque for usable horsepower.. to do that you go in the exact opposite direction a reverse split takes you.

Ahh, see you are saying it yourself, "A cam speced for nitrous".
As we all have experienced, most of us know that that on the street with measely small 100>150 shots, it is better to spec your cam for NA and just shoot it.
What you pay attention to then is Valve events and make it more exhaust biased to facilitate gas exiting after combustion.
A motor combo is not based around the cam but vice versa.
It is not leaving too much on the table if your overall combo is designed to compensate. At these levels, the trq increase over standard splits will translate into faster acceleration.
Bottom line, properly speced at the right valve events with proper supporting mods, it works very well. I know, I do it, I've won championships doing it.
Please be kind, and remove your sig (the blasting part), you seem to have an understanding of what is going on, so try to educate instead of demeaning another member. That is the mark respect and leadership, not what you are doing. How would you feel if Vizard made fun of you on his Web, because you know less than him or did not express yourself correctly?
I'm sure you'll do the right thing

You're right, when you use a car NA 98% of the time, then spec a cam for NA and take the losses you get when spraying. (You know what I mean).

cuz he doesnt understand the difference between hearsay vs. "PROVEN RESULTS"!!!!
IMO FWIW
Predator Z is pretty much on the money with this..."Bottom line, properly speced at the right valve events with proper supporting mods, it works very well". It will depend on application and the supporting parts your using plus what you want out of the car.
Reverse splits proved their place with our LS1/LS6 engines back in the day when the MTI X1 and TR 230/224 were among the top cams available. The extra intake duration can scotched the intake flow of an LS6 intake manifold and usually made more top end power etc over traditional split or single pattern cams in well thought out set ups of era. Many of the 440rwhp-450rwhp+ cars of that era used reverse split and stuck with the LS6 intake. With a better flowing intakes than the LS6, one will likely see overall better numbers with more traditional cam splits. A lot of this also depends on that the heds flow on intake (with manifold in place) and exhaust etc. That's my impression based on the dyno graphs I've seen over the years and the folks I've talked too.
