Motor finally went, where to buy streetport?

Wow thx for the input. Could you please post a detailed report in the performance section? I'm hoping to keep all the RA durability results in that location. There's no way a stock seal would have lasted this long with that kind of A/F ratio on pump gas while at 17psi. I consider this tuning to the ragged edge, yet your engine is still holding up. By the way, how much power you making?

I have never dynoed it, and really have no desire to. However the other night I ran a 2007 gsxr 1000 with exhaust from a 70 roll ( he was in 1st, I was in 3rd gear). I did not brake boost and by the time he reached 160 I was only 3 car lengths behind. Also my timing at 17 psi is 13 deg. at peak torque and 21 deg. by red line.

Really? and how is that.
Kinda stange you would post anything since your handy work on a Power FC can be seen here

Basically everyone is going to have someone that worked out for them and someone that didn't. I always prefer to get a local builder who can build a proper motor, install it and potentially tune it. That way there is never any finger pointing or other BS to deal with.
#34
Find someone local, that way if there is a problem they can't screw you. RA seals can take a beating, just don't seem to make the power that OEM do. I tried to blow an engine running high boost repeatedly, going leaner and leaner and more and more timing, I even had the apex seals bouncing off the housing and motor is still running...

I believe every seal has its pros and cons. I know the regular RA seals can cause chatter if not properly lubricated, I dont know anything about the super seal. Many people like OEM so I dont know what im going to use in the next build..Jason what are your opinions on the Super seals?? Do you see the same chatter that the regular RA seal can cause. Again this is all hear say I read.

I was just saying that your years of rotary service and seeing how rotary's make power and blow up has allowed you to help others.

I have not opened a motor yet that has the super seals. They are all still running (knock on wood). The car we were doing some testing on and trying to get them to blow has the super seals in it. I have a motor coming to us with RA seals that spun a bearing from over revving. Its has about 20k miles on it and I will post some pics once we open that.

Not that I expect you to pay attention to little details, but I am Peter Chhuom. You have met me before I think, I cant remember. GtoRx7 is Logan Carswell just to clarify things. And neither of us work at discount tire, just at our shop every day. Great POS attitude and keep up the outstanding non-fact information!![Lol](https://www.rx7club.com/images/smilies/lol.gif)

Not saying you don't have some sort of point, but I've gotten calls from my mechanic at this time of night and they were just finishing up on my car for the day...
So no, it's not impossible that he's taking a break at 1am..

Its pretty normal for us to work till 2-4am all the time. It helps get work done, and nobody comes around to take up your time. Of all people you might be able to understand that. I dont care what you think honestly, I know where I am and I'm at the shop. Isnt it your bedtime grandpa?

I know each and everyone of you personally. Enough with the insults, seriously. It is extremly childish. Do you guys honestly think bickering over the god damn internet will prove one point or another. Trust me, you are detouring custumers away from one another. No shop is perfect, no person is perfect(well besides me and jesus, lol, this is where you guys laugh) Both shops can coexist without fighting. Nevertheless, I will get to the facts.

and then now this.
quote was found in this thread.
Jason, that is rather contradictive. On your first quote, you say only fuel starvation and timing makes motors blow, so now intake temps matter? Why the sudden change of heart? You also say that OEM seals are junk, why do most of the race teams use nothing but OEM parts. Is it becuase the Aviation seals allows for much more tolerance due to a shitty tune? How many times did Jake Kellers' motor blow? Once, afer 90 miles on it after you tuned it(motor was broken in properly), then again when it spun a bearing. Honestly, hot weather didn't spin the bearing. Either a bad build or loss of oil pressure did.
Logan, you have a potential blown motor on your hands, so far you have done(in my eyes) the correct way to make it good, offer a free teardown and find the culprit. My money is still on the weather/PFC/Stock Intake manifold.
Good luck to both shops. Both of you are DAMN good at what you do(this includes satisfying customers and making yourselfs look like jackasses by arguing on the net). However, you both will have me as a lifetime customer.

P.S. I could continue talking ****, however I will let everyone else do it, they are obviously better at it than I am.

The problem is there are other parts to the system that can cause a motor to detonate other than the tune. Injectors, fuel pump, filter, crap intercooler, boost creep etc... can all cause detonation and a blown motor. Doesnt matter how good the tune is. Mazda seals dont hold up to any detonation. If you are planning on upping the boost and going for more power then I wouldnt do mazda seals. I dont care who tunes the car, its not worth the risk. We have seen many motors where the customer said so and so tuned it 3k miles ago and it blew up. Come to find out it chipped a seal.

Ty you need to get your facts straight.
Since your first quote is refering to twisted7's car, there is no doubt that the Power FC was not setup correctly from the start which is most likley the cause if his blown motor. The settings were so off that it was obvious the whoever tuned it had never tuned a Power FC before and didnt read the book on how to setup the injectors.
If if was setup correctly and looked like it was tuned then I would have never said a thing and we wouldnt be having this conversation. I dont see any contradiction there.
I never said OEM seals were junk, I said they didnt like detonation. I dont recommend them for higher HP applications because as I mentioned in your second quote other things can go wrong. Aviations provide a cushion for some error.
In Terms of Jakes motor we dont know why it spun a bearing or at least I dont remember because its been 3 years. From what I hear his current motor is running well.
I know all shops will have issues with a motor or tune at some point and that includes us. The argument here is whether the Power FC was setup correctly or caused the motor to blow. I never posted anything in public about it until now.
Your theories on why twisted7's car blew are tune issues other than the stock intake manifold and Im not sure who told you that could cause a motor to go.
I do agree that this arguing is a waste of time and has nothing to do with this thread. I will leave it at that.
