I think the discussion on oil premix has been educational. Ryans engine issues notwithstanding, if the thread still includes technical discussion of merit why should the thread die? Hey Gordon, when are we going to see your car on a TRACK?
Crispy

 

I will have to see those turbos when I get up there.

 

I agree, its turned more into discussion of other topics, rather than here's why I think Ryan's motor died. Some interesting things have been passed around about injectors, premixing, etc that I'll check the thread to see anything else. Granted, a new thread could be started since we aren't even talking about Ryan's car anymore, it just happens to be the thread the discussion started in and it just happens to have PFS in the subject that grabs a person's attention.

Not to bring up a sore subject, but I haven't heard how the pending litigation turned out in regards to the lawsuit. Any info or is it in another thread?

Tim

 

What is so funny about it Gordon?
Do tell.

 

Can I please get the whole story on the trial Gmonson. I am in a lawsuit too. I got rear ended by a drunk and am suing, so I'd just like to know the whole lawsuit story thing if possible. Rikki, great spelling improvement.

 

A turbo failure can cause engine damage.

The CHRA went south on my old turbo. There was enough play in the shaft where it would hit against the compressor housing. There are several scars on the housing.

The engine is fine, but I'm glad I installed the stock twins as soon as I heard the compressor wheel scrape against the housing.

Glad to hear the results Gordon. To be honest, I don't know how Peter stays in business now since the RX-7 is a quickly shrinking market, his rep is shot, he only does IS-300's as well, and he dones't have any race contracts that I know of. I just wonder where he's making his money.

 

Ryan,
Since I was present when your motor blew, Im gonna give my take on it. When your turbo's are going, they blow oil out the exhaust from the turbine of the turbo, hence no oil goes anywhere but out the exhaust. I noticed you DID NOT burn any unusual amount of oil out your exhaust before popping your motor.

I told you when you tuned at PFS that your A/F was too lean for the street and you found out when it popped. Im sorry for that.

As for you turbo's, yes they probably did pop, but most likely when you blew your motor, (since you had stock apex seals) they like to blow apart and usually take your turbos with them. That is what I believe happened to your car and if you believe otherwise, your being mislead. I know your going to agree with whatever is told you because its going to be free to you, but your turbos will not cause your motor to pop.........Good luck and hope to see you back on the road soon....

 

this reply is mostly for gmonsen:

listen buddy, if i was peter, I would be happy that people keep rehashing this lawsuit thing. If you're into getting on peter's back and making sure he doesn't do this to anyone else, let the whole thing blow over, and even help it to blow over (my logic will follow). Basically nearly everyone who owns a 3rd gen, and lots who don't, have a basic or skewed knowledge of the fact that peter may be a poor businessman. However, by discussing this case, you are giving him publicity. New, young, stupid RX-7 owners are going to go to him and ask what it was all about. When they get there, if he is as fast a talker and as good a fighter as you say, his persistence will convince them to do business with him anyway. He will run circles around them.

So basically, even though he's getting alot of negative publicity on this, if he is a shrewd businessman, he will see the potential to spin this around to help his business that is "hanging on by his fingernails". Let it die.

Rikki, you seem pretty experienced with turbos, especially now concerning your situation which i am sorry to hear about. I'm looking into buying an RX-7 in the next couple weeks (the bank has delayed me a bit, long story). My question is, is there a good way to judge the condition of a turbo system on a car without a boost guage besides a visual inspection? Anyone's input would be appreciated. I did a search and didn't come up with anything. Thanks.

 

Your logic is flawed, I'm afraid. Negative publicity is still negative. People will hear about PFS with or without Gordon's posts. All they'd have to do is search this forum or the archived posts on Steve Cirian's web site, and PFS will come up frequently. Far better that people are forewarned against what may possibly happen to them. I shudder to think about how many people may have been screwed if I'd chosen to keep my mouth shut about Hayes Rotary and my experience with them because I didn't want to give them any publicity. Forewarned is forearmed, as the saying goes. If by my actions I prevent one other person from going through the same experience, then it was well worth it.

As for externally diagnosing the turbos, unfortunately no. They're not even really visible in a stock or nearly stock engine bay, and there's nothing you would be able to tell about their internal condition that an outside view would tell you anyway. A compression check on the engine and a temporary boost gauge to monitor the turbos are going to be your best (and easiest) means of determining the relative health of a potential candidate for purchase.

 

jimlab,

thanks for your info on the turbo. i'm actually leaning toward purchasing an RX-7 i found with a 36,000 mile warranty as long as the warranty is not a scam. I actually have a couple questions for you and the rest of the forum though. Is it possible to rent compression equipment and do a compression test myself, having a professional interpret my results? If not, what's my best bet to compression check a dealer vehicle? Also, would i benefit from having the dealer remove the intake piping and obstructions so I could see the turbos in plain sight? Maybe then I could assess the condition of the bearings?

Oh and congrats on your project. I dont' think I've ever come across a better planned project.

Unfortunately, I'm gonna have to disagree with you from a marketing standpoint though. Granted negative publicity is negative, and you may deter the more intelligent consumer from doing business with Peter, there is a sucker born every minute. Negative publicity is free publicity, and negative publicity is better than none, assuming Peter is as shrewd as people say he is. In addition, if he is as unscrupulous as some people believe, he will have no problem using is knowledge and fast talking to con the next young kid who inquires about his credibility and quality of work.

For example, he'll throw a free port and polish at them, which costs him only the value of his employees' time. Then he'll have a new customer and a supporter because the negative publicity got his name out.

Obviously, you have a great point in that the negative publicity will scare away all the true car enthusiasts, but if every rx-7 was owned by a true enthusiast, the junk yards wouldn't be littered with them. I think my point also holds some water. Cheers.

Dan

 

itr,

I see your point about having some publicity is better than none.

I learned from my friend's franchise business that it still does hinder a lot of business. Statistically speaking from the food industry, 1 negative experience will lead a person to tell 10 of his/her friends about it (biased version I'm sure).

Sorry to deviate yet again from the thread subject.

Those A/F numbers are pretty high if you're on boost. I tuned my previous FC to have 10.8 at 15psi just for good margin.
You can tune the idle and cruise for 13's and 14's. Low boost (<5psi) could be as high as low 12's. I would tune the higher boost to be around 11.2 to max boost being 10.8.

Good luck, man!

I for one am glad Jim posted about Hayes, although I don't know how he had time to post about it since most of his time is been used up by his V8 project the past 4 years Between him and the local rotary shop getting hosed by Hayes, I now know if my motor goes, its not going to them or coming from them. I just hope others know about them now since its died down abit about them.

Tim

 

I've been afraid in the past when I see people who have a billion posts on here, which some people take as that person knows their rx-7 stuff, telling people to tune for 12.0 to 1. I just cringe and know that anyone who listens to that idiot will be posting about how fragile the engine is after they tried to tune it. The highest I've ever seen from the rotary tuners in Japan is 11.4 to 1, so being just a tad richer at 11.2 to one makes it even safer. I had an extra exhaust bung welded in to help me tune my PFC for the larger secondaries, shooting for the 11.2 to 11.4 range.

Tim

 

I just wanted to chime in on the publicity topic. When my motor went pop, I considered Hayes, but did not go with them once I read the negative experiences of their customers on the forum. Of course you can't make some people happy or maybe there could be an honest misunderstanding, but there were quite a few people complaining about Hayes. And even before I heard about this Gordon vs. Peter thing, I wouldn't have sent my car to Peter, due to all of the people complaining about his personality. I would rather deal with someone who isn't characterized as arrogant, there are many other good shops to choose from. So, I guess you can say that I believe that no publicity is better than negative publicity.
