I mean wow.. im around the 1500 mile mark on this engine.. see the video for a description.. im on my phone and its alot to type.. basically i got low compression on rear rotor an even 45 psi on every bounce.. im seriously ticked now..

skunks

was it tuned? how much psi you running? what injectors do you have? sucks but it could be worst. did you rebuild it yourself last time?

Ston3dSnip3r

The motor was built by bryan at rotorsports racing in NC.. after it was built it went straight to the dyno shop right down the street from his house.. i noticed while on the dyno it would bust up real bad on the top end.. not every time but sometimes.. he said it would be fine and to just change the plugs.. we did and it didnt do it again for a week or so.. then i had the clogged injector (previous post) got that fixed and it seemed like it wanted to bust up again but it would only do it WOT in first gear when the tires would spin it would happen.. and only at like 6500 and above.. any time it would happen i would let off immediately because i didnt know if it was detonation or not.. but it just erks me that bryan was so passive about it.. also after the motor was built my knock sensor was going off alot more on the power fc but he said the knock sensor was too sensitive and they usually just disable them. Well it took a couple weeks for Top Speed atlanta could get me in as they are a very busy shop.. Doug (the tuner there) has quite a reputation for being an excellent tuner and i noticed when he was doing some baseline pulls and he heard the busting up he would IMMEDIATELY let off.. this isnt his first seven tune he obviously knows what he is doing. He showed me the ignition timing bryan had set compared to some other rx7 tunes similar to my setup and pointed out that the map was WAY too aggressive.. it was color coded so it was very easy to tell.. well he fixed that and did one more pull and when he left off it came down to the crappy idle.. he said hhmm shut the car off we did a compression test and that was the result. the car was running at 0.99 bar the whole time even the break in period.. i was very careful with the car always check my fluid levels always monitor my plugs i obviously didnt wana throw away the 13 grand i just spent on building the motor.. i just dont know what to think at this point..

skunks

oh nm, didnt see the end of the video. I wonder what your a/f ratio was after the tune. you would think with that much money in the engine, they would give some kinda gaurentee.

Ston3dSnip3r

Yeah well i dont wana sound like im trying to have a pitty party but its the story of my life lol. I tryed calling bryan friday around 2 when it happened he didnt answer.. ill call him monday and how much you wana bet he is gonna be like "oh blah blah blah racing motor cant give a guarentee.." dont get me wrong bryan was a VERY nice guy.. but nice doesnt get me what i paid for..

skunks

well racing motor or not, its not like you raced it. You went to get it tuned by a reputable tuner so I'd expect some kind of gaurentee.

Bryan is here at deals gap so that's probably the reason he didn't answer....so you were running 14 psi during break in?

Also what all was done to the motor...Tell us more about your setup. Dyno pulls already on a fresh rebuilt motor and you had injector issues damn man

allrotor93

Ignore my post

Ston3dSnip3r

Actually derex the injector problem was because after getting the car back from rotor sports i found that the oring for one of the primary injectors was crooked (wasnt before it got sent there) and eventually swelled and was blocking fuel flow that was fixed and the car was fine put another 300 miles or so on it before i took it to top speed.. and the dyno pulls were not on a fresh motor it had a good break in period read the previous post and you will find out whats done to the engine. I just got a call from bryan and he said he will work with me.. so i guess we will see what happens.. work with me sounds like i will be spending more money

I can guarantee you were doing a little more aggressive driving than you say. Lol. I've done it since day one of my rebuild. But sounds to me like you need to talk to your tuner. If he had it in his hands running and even stated your map was crap, and still ran it on the dyno..... hmmm. Then the motor is hurt afterwards..... Hmmm. Make sure you are pointing the fingers at the right people.

Hope it all works out for you.

Ston3dSnip3r

SMH ok first off you cant guarentee anything about the way i drive because you dont know me.. so you can cut that mess short. Second it looks like you live pretty close to bryan so if it were up to me id say ur taking up for a buddy but thats cool whatever im not going to get into all this drama thats for little girls. So in the future, dont guarentee something about someone you know nothing about it makes you look like a dumbass... hhmm. Now i stated before the car was spitting on the top end AFTER the rebuild bryan knew about that problem IT WAS NOT happening before the rebuild. It made me nervous that he was all the way into boost with the problem and noticing the knock sensor going off (wasnt before) but i trusted bryan and was guessing maybe it was because of the aggressive port and the ceramic seals.. he assured me it was nothing to worry about..

i personally felt uncomfortable about the way it drove but it gets me back and forth to work so i would just keep it out of boost because it did fine on the bottom end no probs.. About topspeed.. he asked me if the car drove fine as he loaded it onto the dyno i told him about the problem i was having so he did like three medium pulls straightened up my shitty idle a bit and did a hard pull and noticed the problem immediately.. he told me it was dumping fuel to help stop detonation.. actually started looking at bryans tune and noticed the weird ignition map smoothed it out and did one hard pull and thats when it came down to a shitty idle.. do i blame it on doug? No. i dont know him personally so i am not taking up for him but i know of his reputation.. and he IS known as one of the best tuners on the east coast. This is not his first experience with rotaries.

The problem was there since the day i picked it up from rotor sports so i would say its the builder. I felt like he was brushing off the issue like its no big deal but maybe thats me. regardless i feel like i didnt get what i payed for. For all i know the damage was already done from driving the car for three weeks on a shitty map that originally was designed for a guy named neils car (600bhp rx7) and was modified to work on mine this is exactly what bryan told me.

But really all this bullshit aside i payed top dollar to get an engine that i told bryan i wanted to be reliable spent the extra money for the better parts and 1500 miles later it seems like im **** out of luck but hey i guess we will see.

Ston3dSnip3r

Let me clarify.. Bryan is a really nice guy.. and he did say he would "work with me" i personally dont feel that i should pay for any repairs i payed way more for him to build that motor than some others would have charged me because i heard he was good with a rotary, and payed extra to get these cooling mods he sold me on.. told me that ceramics were the way to go they can take more abuse blah blah blah got my intake extruded and honed all this stuff i got plus selled on i didnt say no to any of it got new housings payed all this flippin money for it and 1500 miles later its ****. thats how i feel. like ****. i felt i was doing the right thing by going the extra mile and getting it built right instead of buying a used one and throwing it in for like 2 grand. at the end of the day who gets the short end?

You are getting the short end because YOUR lack of knowledge. I have had work done with Bryan and everything he did was outstanding. I like you dropped off my car and spent too much money ONLY because I was overseas and unable to monitor the build process. I like you again lost an engine and I know exactly when and where I lost it. I have learned from that lesson and will past that knowledge on to you.


Once you get your motor redone DO NOT waste your time or money allowing shops to tune it. Set up a tuning session with Kan, BDC, Enzo, or someone who is a dedicated tuner and has a good reputation in the ROTARY WORLD NOT in your small local area. Locals will support their local shops and not inform you of some of their mistakes where as you get more accurate feedback with known tuners.

Ston3dSnip3r

lol ur right about that.. and where does ur tag say u live again?

Exactly hint-hint; I lived in Savannah GA when I had my engine issues. I had to drive it to NC for repairs and pick up a rental since it was my daily driver. You might not be thinking about all of the hassles dealing with the NC-GA trips but after awhile it will take its toll. Do it once do it RIGHT!!!!!

I live in South Charlotte and now have the luxury of TWO popular rotary shops (Rotorsports Racing-50 miles or RX-7 World-30 miles) which I have had nothing but positive results.

Ston3dSnip3r

.... really man? i dont even know what to say to you right now.. but its fine im sure other readers are laughing real hard right now..

Ston3dSnip3r

im sorry i just dont know how to respond to that without insulting you and thats not what im here to do so ill let it go.

I didn't mean to come across as a "know it all" or anything of the sorts. Believe me when I say I'm still learning and this is my third 3rd Gen.

My biggest point to you so you don't have to come back here with another "I'm having a little problem" thread is to get a WELL KNOWN TUNER!!!!!!

Im the "Neal" guy u r referring to.. I met you at bryans. I talked to you and we chit chatted about a few things.

1) first thing you said was "man how u feel about bryans tuning". I was like im cool with it and have been running his tunes for years. Also if you remember i said bryan is a old school guy. Loves a good runing, 300-400hp rx7. The 500-600hp seakers like me he laughs at. U were saying how fast the car is and u were happy to get it done so u could go drive it.

2) i was there again when u called saying your motor had problems. U were jumping to conclusions saying the motor was toast. I heard bryan said to check a few things. I gave him my old injectors so he could send them to you to see if that would fix the problem.. Apparantly it did. Hooray. Again you were concerned with bryans tuning and still drove the car. U can deny all you want about boosting, not boosting, etc. But with you saying it was breaking up on the top end that tells on yourself.

3) Im not trying to bash you, and the internet makes people seem harsher than they need to be. Bryan said he would work with you so that should be good enough. I have and many more are running Rotorsports Racing motors... harder than u say u ran yours without issue. So i apologize for your loss and hope you can get things worked out. But remember a motor cannot blow by itself. U have many factors that lead up to the destruction of a motor. A new motor with a old problem = a blown motor again.

I have a brand new built motor from bryan, i drove to charleston for break in miles and i beat on it daily. Guess what, turbo gave out... radiator is leaking, etc all small **** that can ruin your day.

Good luck to you.

Ston3dSnip3r

Neal.. i didnt have to get into boost to notice a problem.. bryan was the first to drive it when i got there and the problem was present.. if the problem wasnt there he wouldnt have tryed to rewire my injectors and asked me to go by new plugs when he put it on his buddys dyno.. and FYI your injectors did not fix the problem.. they were sent back because the problem was when he (or one of those kids there) installed my fuel rails and injectors one of the orings was crooked and swelled over the top and therefore was blocking fuel flow.. yes i agree sometimes the internet may make people seem harsh sometimes.. and i dont want to seem like a douche.. but im not one of these little kids that has to pay couple hundred here and there to barely cover my rebuild i basically just dropped him a large chunk of money over a short period of time and i wanted it to go as planned.. thats why i payed what i did i was trying to avoid future complications so when **** like this happens INSIDE the engine after 1500 miles i would imagine you could understand my disappointment. But thats fine i knew he was gonna have buddys on here come and try to take his back but honestly i just wanted to document my experience.

Ston3dSnip3r

and since we are bringing all the cards to the table.. i hate to put someones business out there but the reason i asked you that question is because of the busting up problem and because guy at the mustang dyno basically told me not 20 feet away from bryan "yeah he is a good guy and builds good engines but he hasnt been the same up there since the wreck.." that was after i dropped the 14 grand and there was no turning back so yeah i must admit i was having doubts in my mind. But all that is irrelevant at this point i spent the money and its gone and if i got to drop another 14 grand then i guess thats just the way it ******* goes.

Ston3dSnip3r

Reading back through this i can see how i may come off as a ******** and i apologize im not trying to be an *** and im not saying bryan doesnt know what he is doing.. pls dont misunderstand.. im just suggesting maybe something was overlooked.. or maybe it could be a fluke and one of the side seals went out or something i dont know.. but im just like any other guy who goes out of his way to try to get something done the right way and when it doesnt it just kinda puts me in a bad mood so if i come off as just a dick i apologize..

Hopefully everything comes together but i have had nothing but problems out of this beyatch i spent 14 grand on the car it had 74,000 miles on it everything stock ran good before i started upgrading i pretty much dropped like 28,000 in parts tried to get all the best stuff i could find it ran great until the motor popped (my fault it was due to a power cut i didnt know i was getting) and since the motor was rebuilt it seems like everything has been going downhill.. i used to have dreams about owning one of these yes before that stupid movie F&F came out i loved the idea of having such a unique setup and it was like heaven for a few weeks.. but at this point im like **** dude i might get it tuned to like 12 psi and find a decent trade or try to sell.. this thing is gonna break my bank.. hell it already has what am i saying lol.

FD. Financial Disaster. It seems like you've had a pretty bad experience with the rotary. There really is a lot of research to be done on these motors as they are EXTREMELY sensitive to problems a normal piston motor could deal with. How long did you research your set up? You did mention that you had break up in boost or up top. That is saying something big. The issue with the injector o ring being crooked is definitely an issue and it's good that that was found. I've never personally met Bryan or anyone at rotorsports but I have spoke to him on the phone a time or two. What concerns me slightly is that if your motor had issues running after it was built, why did he allow it to leave his shop? Personally, if I built a motor for a customer and it was having drastic issues like fueling I wouldn't let my customer drive it away because something like this would happen. We all know what happens when a motor leans out. I have heard several success stories about Bryan's work as well. It seems this is just another one of "those threads". I can only imagine the pain that your blown motor has caused you after all the money you spent and it probably sucks. Makes me scared to do anything to my seven honestly. But I feel that with enough research and ensuring everything is properly prepped, set up, broke in, tuned, monitored, and driven, you shan't have a problem with the rotary.

Again it sucks. But what can you do?
Matt

Ston3dSnip3r

Thnx bud.. yeah it does suck but bryan said he would take care of it so i am crossing my fingers.. just kinda adds insult to injury when his buddies come on here and are quick to say oh you shouldnt have drivin it hard.. its because ur lack of knowledge.. its the tuners fault..im not an idiot, im not spending daddys money i am in the Information Technology field i work hard for my cash and yes i have been reading up on sevens for a good while, i owned a 10th anniversary FC before i got my FD i just feel that maybe this one is cursed lol
