It may be that some issue other than octane caused the detonation that took out the apex . But I still say you are better off using e85 as an octane boost additive than the concoction you were running . I settled on 30% ethanol in my setup and have found that is way better than any w/m combo I tried before that . Worth 35 mile trip armed with a few jerrycans ....... IMO

Looking for some advice on porting. I have ported my exhaust ports out to the EPA-4A template from Pineapple, so I have added significant exhaust ports (51 mm x 35mm).

I purchased the Pineapple BP template as I plan on doing a half-bridge. The relief port pretty much mirrors the length of the secondary port. I also see other templates that only use a relief port that is half the length of the secondary port (partial BP). As I understand it, the full length relief port will give significantly more overlap, which will product less vacuum and require higher idle. Use of the relief port that is half the length of the secondary port (open later), will reduce overlap, produce more vacuum, and idle somewhere between a full length bridge and a streetport. I hate the idea of idling around at 1800-2000 especially with the temperature in Florida putting the cooling system on the edge.

Is doing the conservative relief port (starting further from the exhaust port) worth it? Or should I just sack up and do the full length BP?

I already have all the gaskets and my new RA Super Seals waiting to go in once I make a decision on the intake ports.

Update: Well I went ahead and shortened the relief port by 20mm (32mm instead of 52mm). More of a partial bridge with a bit less overlap. I did a minor notching on the rotor housing. Next rebuild I can always make the port larger. I kept the bridge on the wide side. Still waiting on the mail man to deliver my new RA super seals. Hopefully they will show up and I can get the motor back together tonight.

I was going to suggest RA Super Seals as they claim they don't break, just wear. I am curious to see how you like them.

Well the post office lost my seals, the tracking number hasn't been updated in 6 days. I had to request an investigation. RA says they have to wait weeks in order to file a insurance claim so I am out in limbo. I guess I would expect nothing less from a organization that loses $6,000,000,000/year.

Hits just fine. I am using a high-mount turbo setup with 2" primaries so spool isn't great. 10 psi by 4,300, 20ish by 5,000. I am now going to a partial bridge-port, so I am hoping I can improve on both of those by a few hundred revs. I have a datalog on here that shows the turbo pressure coming on.

I finally received my RA apex seals. I was fitting them in my rotors last night, and they are much more snug in the rotor grooves than the Atkins seals were. They appear to be slightly thicker. I am wondering whether I should take some emory paper to the apex groove, or the seal itself? Im guessing that I only need to remove a 1/10 of a mm or two to get the seals moving easily through the slots.

I have been so busy with life lately that I havent been able to put any time into getting the motor rebuilt. I hope to make some progress on Saturday.

A view of the difference of the RX8 5 speed vs 6 speed. The transmission is much beefier in the 5 speed, bellhousing and tail shaft are smaller.



After installing the new transmission, balancing it on my jack, I found that the 5 speed has a dowel on one of the upper passenger bell housing bolt holes. So I had to pull the entire transmission down and drill out the dowel so I could install.




engine and transmission are in, now I just have to hook up everything else and can start.

Got the car fired up this morning. I have to hold the throttle open to keep it running. Seems to run fine at 1,600 RPMs. If I let off the throttle it slowly dies due to the Bridgeport. Before I started I was 89 PSI in the front rotor and 81 PSI in the rear rotor. Its a real PITA to start with an old battery and a freshly rebuilt motor. I will have to drill out the TB a bit more to get a 1,500-1,600 idle. Vacuum was 8 mm Hg at 1,500 RPMS.

Car definitely braps, and the exhaust is a whole level louder. Gotta break this thing in so starting is easier.

Update: Have run the car in my driveway for a few idling sessions of 30 minutes. Vacuum is coming up (12mm HG at 1,600 RPMs) and car is starting easier. I drove the car around the block, and it was smooth. Other than the higher idle, the car drives the same as it did before. Transmission seems fine.

Quick Video of the car idling. Car has 3 resonators and a large muffler, so the exhaust is pretty tame, even with the new port.
