Emilio has posted a bunch of header data somewhere that escapes me at the moment but I would imagine its relevant as flow is flow. (I think its in the 200hp N/A thread)
Cliffs: RB is the way to go for domestic OTS product.
I believe one of the other big-power rotrex guys is using a modified RB. The 2.375" OD secondary tubing was cut off and like a 2.75" or 3" secondary welded in its place to match the rest of the exhaust. I think I read that over on m.net? Dunno, its been a while since I've followed any of the rotrex builds.
What'd you buy, a Raceland or OBX or something?

In a moment of weakness I purchased a new C30-94 Rotrex. The compressor map just looks like a better match for the free flowing head/cams.
I was reluctant to add more HP. That's not what this car is about. It will end up in the upper 300's at the wheels. Torque should be 250ish at the wheels. I don't know if that's gonna kill reliability and drive ability. It should help those corner to corner drag races with the big power guys. Once the sequential goes in things are gonna be really sick.

Do you have some inside info on the Jackson Racing kit that others don't? That thing is years overdue now...

No insider word on the JR kit other than knowing Oscar is working his tail off on other projects.
Aidandj, No issues with internals. Fully built motor. My comment about reliability was directed towards trans and diff. The valves have been taking a beating with the 8k redline. I'll back off that some with the bigger SC just to help buy more time between rebuilds.
