Thought you might be interested in the latest dyno run --
11 pounds of boost, conservative (meaning safe) map.

I have the same exact thing done inside my 13B-REW the jackets around and near the spark plugs are finned to create more surface area and create a tumble as the coolant crosses through.
There is this really neat Appalachian Hillbilly that lives in Port St. Lucie Florida, his shop is called JR Fabrications (formally Just Racing Fabrications) and he did some amazing work on my engine.
I also never saw apex seals installed while the rotor is in the housing. I have seen neat plastic holding devices that let you slide the rotor down. Or, the low tech rubber band method.
On my REW I found big torque gains when we opened up the throttle body and intake runners, as well as an aggressive street port. The intake runners and TB were opened an easy 20%. The low end grunt is seat of the pants noticeable.

Are those MSP rotors or did they use lower compression out of a diff year? Just curious because i know they Apex seals on the rene are different than standard 13b Apex seals. I have the irons and really contemplating doing a similar build.

Brettus had his rotors machined to take taller 3mm apex seals for example

right, but the compression of the MSP is higher. not ideal for boost application. i suppose i should look up clearances and compare my question was more of if another rotor was used would there be tolerance issues with the ports and dropping a seal.

High compression is not an issue in boosted applications if you know how to tune. Less margin for mistakes, that's pretty much it.
