Hopefully water-cooling will help and I can copy that too lol. Good luck.

I have been studying my waste gate issue and I am pretty confident I have figured out the problem. I still plan to run coolant though them since I have water cooled waste gates but I do not think they are getting over heated. The cause that I have figured out is that I was using the Anti lag function on the Haltech and that was the cause of the burned up waste gates.

here is what I have thought about.

1. I raced my car for half a season with out any issues.
2. I used the Anti lag launch function at a couple of races mid way through the season.
3. Next race blown waste gates. I repaired the waste gates after I found the problem. unfortunately I raced at the Toledo Ohio Solo with low boost as a result.
4. New waste gates installed for Nationals, first day of Pro Solo ( using ALS ), resulted in low boost for second day. I finished third but maybe the Low boost helped more than hurt.
5. Turned ALS off for good after that and I have not had an issue since. Also the waste gate that had the most damage was the rear one. Yes, it is closest to the exhaust but it also has the most direct "straight" path from the exhaust.

Haltech has a disclaimer on using the ALS they should ad "will destroy waste gates"

Also added more pictures for ABS, Diff brace and exhaust tip.

It's def. the offseason! I was extemely happy with the engine David built for me a few years ago. Using ALS seals?

Paint those ugly fenders

What's with the exhaust tip? Maybe I missed it.

I'm SO glad you figured out the wastegate problem, because that means I won't have to run water to mine LOL!

The exhaust tip is adjustable, I can point it to the left, right or down. I have a spring that hold it in place. Also you can see each hook for the three adjustment points. The adjustment is to direct the exhaust away from the sound meter on the course. We have a 100 db limit and mine is anywhere from 92 to 98.5 dbs.

Oh OK gotcha. I figured it was so you could point it but I couldn't think of why. Makes sense haha. I'm surprised they let you do that, I figured they'd have a cow about that.

As a part of the relocation, did you separate out the ABS ECU, or is it still incorporated into the full body harness as from the factory? Supposing the latter, do you have any intention of separating it out and removing all that excess factory body harness for weight savings/wiring replacement and simplification?

Thanks again for sharing so much of your build. Good luck with the continued project.

Yes, it is still incorporated in the harness, I do not have any intention on doing anything else to it since it is working.

I started making a new oil fill neck that I will ad a catch can to later for my vented PCV set up. Also I am trying to get ready to dyno this weekend. I will try and update everything before my dyno tuning session. I also added a picture of my two helpers.

Love the welding jig Carter.

[cturbo28]

Some more pictures of the over flow tank set up and new DS2 coil mounts. I did ad a vent line to the rear turbo drain which feeds the other side of the tank. I will let everyone know how this turns out in an Auto-X. Hopefully I can keep from spitting out half a qt. a run.....
Slow progress but it is getting together slowly. I also tried to Dyno the car last Saturday but I will go again due to some boosting issues I had.

The season starter will be held this weekend at Georgia Motorsports Park.

I added some pictures of my weekend project. enjoy...

[cturbo28]

The rx7 survived the weekend. I placed first in the season opener. Although I was a little rusty I still pulled out the win. Here are some pics of the car in action.

[speedjunkie]

Damn that's sexy.

Great job Carter! Car looks good as usual!

[cturbo28]

I have started some new top secret projects moving some weight back and right. I am just now fitting everything up and seeing if things are going to fit all together. If anyone has any ideas or suggestions I would be glad to hear them as some times I over think things.

1. EPS

SW20 Electric PS pump moved to passenger side with battery and ABS.

2. EWP

Craig Davis electric water pump, hopefully this will be controlled via Haltech PWM output.

3. ALT relocation

Relocate Alternator to clear up some space up top and since I will be loosing my water pump pulley I thought I needed to relocate it. I would love to move it to the passenger side but packaging is a big issue on that side since the turbo and everything else is located there.

Also my new engine is on the bottom of the list. I pulled the new engine out and put the old motor back in after the Dyno results. I will update later on the outcome of the new motor set up when I hit the numbers I want. The last race I did was on the old motor not the new one.
