Clearly going to be a "2 Kev" race after all !
 
Looks nice and clean in the engine - can\'t help thinking that rotaries go togther like some kind of special lego / meccanno

Looks like that was a lucky ebay buy Kev. Have you decided on ports yet?

Ready to be shot down in flames, but I\'m going to put my machining skills to the test and try a semi-peripheral set up. Retaining the primary ports, filling the secondary ports and adding peripheral ports.

Will then machine either throttle bodies or slide throttle with control over when peripheral ports open.

Comments positive and negative welcome.

Looks like someone\'s ignition setup was a bit shoddy.....

[kev-yorks]

Go for it kev.

wow, you two are monsters :Giggle

Going to be some scarey stuff next year

The wife thinks its a mid life crisis Shaun i\'m getting dafter as i get older. But with this namby pamby government where stuck with, how long will it be before they stop us running slightly overpowered motors on the street so lets have our fun while we still can.

Swap it to LPG and they can\'t charge you congestion charge

Started on some small port mods

A couple of pictures and video on youtube, showing machined rotor housing ready to take alloy plug to be convert to peripheral port.

Port will be quite high to try and keep it drivable on the street( i hope)...

Makes me wonder if anybody has done an elongated PP. Surely with CNC machining you could do quite easily and have it like 55x80mm Ob-round. CNC the plug to the relevent shape cut out of a larger blank with a machined boss.

Very cool, long time since I used a milling machine

I am going to fit a blank plug then CNC machine a D-port similar to this one.
OD of plug will be 60mm and as you can see I have not machined all the way through housing.

I will be aiming at a smaller higher port by machining a 44mm Dia hole straight through then setting up at an angle to machine flat at exit in housing, but keeping round at the front.

[shaunwil]

I did notice that ! is the plug just welded into place ? This will give a different sound as well won\'t it ? Does it reduce the overlap between the ports ?

Can\'t wait to see how its going

I have now machined a scrap housing to peripheral port complete. I have kept it high and tapers from 50mm to 42mm. This is quite small, but I hope to keep it drivable(ish) on the street.

I have also got plugs in 20B housings ready to bond in and finish machine.

[FD3UK]

A bit more progress.

Housings machined ready for hand finishing...





Exhaust flange profiled and sat in car to cut and position exhaust tubes...

Great project.  Nice to see something something different!  Nice machine work BTW.
