3 sizes is a bit far for rotor weight but I don't think that had anything to do with busting an apex seal. I would be interested in looking at the bearings though.
I've been happy with the RA kits.

* The car was really not "track worthy". While it did last 2 good years of tracking, I never invested the money to really make it last on the track.
a) Not using race gas on the track
b) Running too high of boost on the track for extended periods
c) Engine temps soared while in the middle of the session. I didn't have a gauge with peak warning (that will be changed) so I have no idea how long my temps were beyond the point of no return. While there was no warping from the heat, I'll bet that the heat coupled with leaky injectors and lower octane (and an old reman) was the combination for disaster.
The problem is that this track session was the first time had I used R-Compound. I had been using some old crappy Goodyears for the last 2 years which were crap on the track but I was never able to push the car hard enough to worry about anything. The R-Compound allowed me to run the car a lot harder than I had before in which case it just couldn't handle it at it's current setup.
So, the some things that will remedy the problems which are going in:
Aluminum Race Radiator
Mocal 19-Row oil cooler
Ceramic coated parts to help keep the engine from ingesting too much heat
Replacing my temp gauge with one that has peak warning (as when I'm on the track I'm not starring at my gauges all the time.
Had I not been tracking the car, the engine would still be running (but I wouldn't be enjoying the car nearly as much).

Looks good. I'm glad to see your doing a good job!

BTW, for anyone curious about the weight of the sound dampening material; the packaging came to me weighting in a 12 lbs. I would guess just under 10 pounds without the shipping material/box.

Do you have specific pics in mind that you need brightened? I say adjust your monitors brightness and contrast.

BTW, I'm a little surprised on those prices for polishing and coating. While not exactly cheap, they're not as bad as I would have expected.

No problem Art,
I'll be waiting for the second batch of parts to come back maybe next month. I know you have at least 2 or 3 engine installs lined up so I'm in no hurry. Mr. V8 MX-7 (that's what I call it since it no longer has a Rotary engine in it) should be out at the track.
However, I now have something else I can track for a little bit (if I decide to) until the RX7 is back up. If you are instructing next Wednesday, you'll get a chance to take a look at it.

We don't have emissions testing here, but we do have visual. The inspectors aren't really that smart around here as they think Borla mufflers are cats. I just like keeping some added back pressure. My goal is to keep my car "quick", I'm not going for some super high-end powered car for the drag strip.
* HKS HiPower Catback
I like the "angled" catback so this was a good excuse to change. I've heard more HKS exhaust drone at highway speeds. So to make sure I can compensate a little, I add the sound dampening material.

BTW, here is RTS3GEN's car at that track event:

Awesome thread. I don't know much about the Pettit ECU, but for some reason I think I've heard that it's a daughterboard that plugs into the stock ECU, mostly to change the fuel maps and timing, but not replacing the 8-bit processor itself. If that is the case, I'd recommend you ditch it quick-like.
Here's a link to some stuff I've posted before with reference to the differences between 8-bit and 16-bit ECUs, as well as the common processor speeds in 1993 compared to 2000:
https://www.rx7club.com/showthread.p...9&page=1&pp=15
Remember, one of the things that was updated each time there were significant changes made to the RX-7's overseas was the ECU. In '96 and again in '99, from what I understand.

If you take a look at RTS3GEN's car up there, it made 359.x rwhp on the Pettit ECU. He's been tracking the car for going on 5+ years now on the same engine and same ECU (road racing, drag, etc). However, his car has been built for the track, mine was not.
The ECU is not the cause for this engine failure. The cause was putting the car in a situation it was not setup for.... I knew this and did it anyway so there is no blame pushed anywhere but on myself. Had I not been tracking the car, the engine would still be in one piece today, carbon or none. However, I would not have been having as much fun as I was... This time out, the car will be built to handle being driven on the track aggresively.

I also know a few guys beating the crap out of the car on Pettit ECU's.. You would "think" they have some idea of what they are doing, yes? I think you're on the right track - keeping the ECU and building around it.

I think I always had a complex with "if I knew then what I know now" things when thinking back to having the dealership install a reman (and new turbos) way back when. So, this was an opprotunity to "do it my way". If my way sucks or doesn't work, it at least it will be mine.

If I can get around 330-340rwhp at 14 PSI, I'll be extremely happy. RTS3GEN made 359rwhp but he has a Race Port so I'm not expecting his numbers.
