Nice to hear it without hearing it. Being 500 miles away sucks. I have full faith in Jesus.y wife did say it sounded beautiful, and she hates my car.

So if my eyes don't deceive me you're running the PP thru the irons and into the housings??? I've never seen it done that way... I've always seen it machined directly into the housings bypassing the irons

How do you keep water from the water jacket out of those? Did he just RTV it around those?

So are you using the stock intake ports in the irons as well?? That's a lot of intake!

Partlymazda (John Doughty) of the infamous You tube Video "Rotary engine class" used to do the same thing years ago to get around porting rules in race car engines he used to build, but his was one big port.

Sense you are also using the side ports I don't know if you will have the same characteristics of a straight P port, but if you can't get the Idle down enough to tune it good Partlymazda told me that if you retard the timing till it runs smooth at idle (30 or so degrees) you can do all your adjustments then reset the timing.

Don't know it this will help anyone but it sure can't hurt. Partlymazda if i got anything wrong please chime in.

Thank you very much for the tips from partlymazda. We already figured the the idle will have to remain above 2k, just writing for the break-in period. The aim was to get a lot more power starting in the midrange all the way to redline. So far it is just as well behaved on the street as my semi p-port Bridgeport. I did not port higher on purpose, I wanted the most port in the useable range without having to Chase to 10k. So far so good.

The setup made the most linear dyno graph I have ever seen. I wish it had lightened rotors in it so we could chase the peak. I'll leave Allan to post the number but I must say that it showed no signs of plateuing.
