please don't make this another V-8 vs. rotary thread, there are other sections of the forum to carry on that (very) tired discussion
best of luck David....good things come to those who wait (well, usually
) I hope that will be true for my car as well
look forward to seeing you in Asheville with this monster in the future

Tell me about it. You got to compare apple to apples. There's no telling what a Viper V10 is really capable of with tons of boost. Bigger displacement makes more power more reliably period. That's why I'm going the 20b route. I would rather make 450 rwhp on a 20b than a 13b anyday of the week.

Cam at Pettit is a great guy and a fantastic mechanic and fabricator. He had several other major issues going on at the time (among these two hurricanes) and I was kind of caught in between it all.
On the negative side, the car wasn't living up to its potential. 400 RWHP certainly isn't bad, expecially with the low end torque of a 20B, but I wanted more. The car drove and idled well. On the positive side, I'm very pleased with the fabrication and the mechanics of the car.
Now, if I can just solve the HP and electronics issue. Wondor what I am doing about that?

I completely agree and am going through something similar with my project and on several occasions have chosen to be pragmatic (translation-spend more money than planned and sometimes with different people) rather than ideal just to move the project along. Building a 20b car is a huge undertaking. It is not comparable to the other projects I have done, including a single turbo conversion. In my opinion it is analogous to building a kit car. For that reason I think it is inevitable that problems will come up.

I'm an electronics engineer, I'm involved with an "entire" custom FD project (as in every single wire/system in the car is being designed and installed by me) and won't be available for a couple months

So, I picked up the car about 70% tuned and spend several months learning the Wolf unit and tuning the car (with the help of my local resident FD expert Dean Colver). We had it running pretty well but just couldn't seem to break the 400 RWHP barrier. Couldn't get boost to hold above 10 PSI or so.
So, I'm now attempting to solve that issue. Hope I'm not in the same cycle as the above - keep you posted.

Damn, I hope you can get it working soon so you can enjoy it. A few years ago, I watch Peter Ferral drive one at summit point and smoked a 650 hp viper there.
He left him like the viper was a honda civic.

Should have stated more correctly, it's a tuning/EMS issue. Nothing wrong with the EMS, it just needs to be tuned correctly.

first david what a show you've been/going through with this!
I read the entire thread...its been raining for about an hour so...lol.
few questions that I did not see adressed.
1.) how much does this thing weigh w/o a driver?
2.) weight bias? maybe you can get it on a 4 corner scale? pretty please?
3.) do you have any regrets to this project at all?...
4.) did you think about a v8 swap at all?
I think thats it...besides drag times or videos!!!

1.) how much does this thing weigh w/o a driver?
Should weigh in about the same as a regular FD. Pettit claims it weighs 2730 lbs but this seems a tad bit light to me.
2.) weight bias? maybe you can get it on a 4 corner scale? pretty please?
Weight bias should be the same also. As for the 4 corner scale, sure when I get the car back and if you (or anyone else) knows where one is in Northeast Florida.
I drove the car for about 5 months after the conversion and before sending it on its way to CA. It drives and handles fantastically well. Remember, I upgraded most of the suspension and the brakes during the conversion so this could be why it feels so good.
3.) do you have any regrets to this project at all?...
Regrets - That I didn't pin Pettit down more regarding the details of the project, the cost, and the timing. I've had work done at Pettit in the past and it has all gone well and on time. With this project, I said "I trust you, do what is needed". Now that I know more about the whole 20B conversion project, I would have gone single turbo from the beginning and I would have written a contract that would have had a "max time limit" and cost on it. Most mechanics won't accept this though. So, with everything I've had done on the car for the 20B conversion and with the current "project" going on in CA, I'll have sunk about $55K into the car, vastly exceeding what I believe I can get for it in return (once you add in the actual value of the car also).
However, I'll end up with something very unique and very kick butt and that's why I did the project in the first place.
4.) did you think about a v8 swap at all?
No, not to flame the V8 vs. rotary debate, but I'm a purist. V8s are fine but they belong elsewhere, not in an RX7. Yes, I could have done a V8 swap for a lot less and others might wish to consider this. If I wanted a Mustang or Corvette, I would have bought one (along with the Hugh Heffner smoking jacket and gold chaines for the 'Vette) in the first place (heh heh, just a little joke).
My feeling is the car started life with a rotary and I'm enhancing that with a bigger, more powerful rotary. So, I've attempted to put the biggest and most unique rotary in it that seems feasible to me, and that's the 20B.
I think thats it...besides drag times or videos!!!
I sent many months ago vids of the car on the dyno to a forum member for posting but apparently they never got uploaded. I will post new vids when I get the car back as well as a final dyno of the car and its capabilities.

Well David, if your going single, expect to loose some of that low end you once had. I'm talking about the 3k and below performance for better around town drive-ability. The older twins give better response and torque down there from what I've seen on most 20b dyno graphs.

, this is possible. Any experiences with the dual BB turbos and their spool up?FYI - the midpipe just left Jax on its way to you.
