lol omg thats not backfire your fucking retarded. thats afterfire first off. its unburnt exhaust gasses that are igniting. backfires would be going through the intake and woulda blown the airbox the fuck off. my SR20DET from the sylvia i got it from afterfired like a bastard after the track tune.
@RotorMedic7 could be loading up on fuel, ( front rotor can do this . mine did. unplug plug wires, and spin it, to clear it out. OR id check the timing as well. ive got an 88 rx7 vert ive got to source another 13b for. or do a v8 conversion
the reason its doin that is there is absolutely no back pressure and it might be a motor that has been redlined too much i've had trouble with that also if you can't keep consistent oil pressure your motors gonna act funny
this school is a rip off, me and 3 of my friends attended here and wyotech never helped us get a job, there are 70 students to 3 teachers, the tools are all junk, the class room is junk as well as the workshop, the instrutors cram so much at you at a time its so hard to know whats going on and they dont got time to go over anything twice, i cant belive this school is still up, whoever is running this joint needs to see whats realy going on
SpideyFan6010, you claim to know a bit about rotaries but its clearly obvious that you know nothing. pulsar 93 is talking about ignition timing, electronic not mechanical. you can't physically change the mechanical timing of a rotary because the rotor is timed to the eccentric shaft, the rotor wont go in if it isnt timed. Porting changes when the degrees before tdc that the fuel can enter similar to adding a large camshaft to a piston engine, your increasing the overlap hence pp, brigeport idle
this doesnt sound like a rotary at all to me... ive hear headders before soo either bad sound quality. i could understand because it sounds like a harley that smoked crack and has a wild heart beat haha.
Never mind then. I wish some of these auto tech schools would offer rotary training. I guess since they don't make up the majority of the engines on the road they just disregard them. I know a lot of people that would sign up if they offered a rotary class but they don't.
they'll teach you all you wanna know about wankels...they're not all that complicated. timing was off by 180 i think on that engine for a while, thats why it sounded like ass and backfired like that
You do know that rotaries run really rich and they naturally backfire like that right. If you are a wyotech student and you came to that conclusion then they must not be teaching much about rotaries. No offense but you pay a lot of money at those technical schools and you don't get that much in return, And your credits don't transfer if you decide to go else where.
dude listen to it !! It sounds like shit...that's not normal, and yeah they run a little rich, but that doesn't change the fact that the timing was off ...That's what we "concluded", and i learned alot there; whats with your animosity? You get kicked out of some tech school or couldn't afford it or something? Chill on the remarks bro when you don't know what you're talking about
what r u talking about Animosity. No where in my comment did I say Wyotech sucks or I hate wyotech. The stuff they teach is not any groundbreaking stuff that u can't learn on Ur own. Is it the Resi 13B from a 1st gen or a FC? I know what I am talking about when it comes 2 rotaries. I own 1 and so does my brother.
how do you know what they teach? Like I said I learned alot. It's also not just what you're learning but how. The proper procedures, techniques and practice that helps all that info sink in is why i went. Plus I just love cars. Why wouldn't you wanna learn everything about something you love? And i'm pretty sure it was out of an FC. It had fuel injection so yea...weren't the first gens only carbed?
I know the GSL are carbed but the GSL-SE is Fuel injected and they used the 13B RESI. My bro just got his GSL so give me some time and I will know more information on them :) It does sound funny though. I would say it sounds like that from porting but It doesn't appear to be ported. It is more of a brap than a low growl at idle.

How did you fix a timing problem on a rotary? Last time I checked it doesn't have any valves or a timing chain. So what exactly did you do to fix it? From my knowledge the only way to advanced the timing of a rotary is to port it. Depending which way you go with the porting determines weather the air comes in earlier or later in the combustion cycle process . Same goes for the exhaust ports.
wyotech suck here in los angeles... we cant work on our own cars anymore

Im guessing thats the one out of the RX7. It had its waste gates welded together at one time. USED to be attached to a bad ass car.

idk , seems to be a problem with the pistons or the connecting rods

are u fucking stupid??!?!?! there are no pistons or conecting rods on a fucking rotary engine. COMPLETELY different
and btw it is a rotary engine u can tell by the 5th and 6th port actuators on the side of the motor.
for those who dont know rotarys. please stfu and learn before you talk. thanks bye

@SpideyFan6010 you time it via the e-shaft position sensor if FI, or via the distributor(s) if carbed.
