Build Or DIE Trying! a 1993 FD story.
some updates this weekend I spent all my time painting and conditioningall the accessories and stuff and replaced the oil cooler . 
Hopefully having the vent will help with cooling.

NEW BOOST GAUGE , and CENTER SPEAKER GAUGE POD
spent some time taking apart the interior passing hte wiring over to the center , BUt will have to finish that during the weekend with some sunlight .. to solder . the wiring

YEAH , Ididnt know they were yours ! , But basically they are for super high revving engines!
And I've watched this video like 10 times already haha

the reason you cant rev a rotary to 20000 RPM is because after a certain RPM , The Eshaft starts to flex and that flex causes wobbling of the rotors ,
So if you lighten the rotors the flexx is LESS on the E shaft
But then , You clearance the rotor , for when it DOES flex even despite the lightening , The sides of the rotors will wobble some and when it does normally the rotors will contact the irons , but by removing and clearancing when it wobbles it has More room where it wont contact the Irons . so you can rev the motor even higher
scalloping what that does is it is sorta the inverse of a port the rotor iselve's edge will be incontact with the port , since you have a limit of howmuch you can port the irons without ruining the engine , This allows for quicker opening of the ports ,
, and then ofcourse balancing at your target RPM range so that when you do Rev the crap out of it any wobble is minimized by being balanced .
basically those rotors have had the WORKS done to them LOL
