My experience happened a llooonngg time ago when I first got into RX-7s...I can't honestly say whether it was a back or after-fire, but I don't remember the air cleaner being damaged. I just remember the kid gunning the engine for some late night flames...pow, pow ,pow and then, suddenly, this giant plume of white smoke started coming out of the exhaust! It would still run but only at high idle. I kept it running long enough for the thermal reactor to go cherry red before I shut it down knowing it would never start again. Thus started the adventures of swapping in used motors from JAP Imports for 1 year fixes until I had the money for an Ari Yallon engine...

 

my 83 pops is that really bad? , only pertaining mods are high flow cats from victoria britsh and a monzo muffler (megaphone) from VB. and a K&N air filter

 

I've got an 83 Rx-7 GS, pretty much stock accept for straight pipe off the stock headers.. (busted out the cats) the thing is loud as a bitch, and right now it's having start problems, and my carb is messed up... just spent 400$ on a stereo, and now the damn car wants more money... anyways, when I race my car, I'll usually take it up to about 7.5k or 7.8k or until my shift lite is blinding me so bad I can't see.. when I change gears real quick, it's the loudest damn backfire I've ever heard.. louder than a damn 12 gauge.. my friends celica was behind me, and he's like dude... you flame licked my car... I didn't even know I was shooting flames...
so is this bad, or normal?

i have a 79 Rx7 GS and it has backfired since the day it was purchased way back in 79. i have dropped another 12A in it and because it has a thermal reacter on it, the Rx will backfire. I think its kinda cool plus u get to say it has a thermal reacter lol kinda blows peoples minds.

 

haha thats awesome, maybe ill pick up at thermal reactor at the junkyard tomorrow, that is well worth sacraficing weight for

 

My thermal reactor '80 used to pop all the time. Between shifts, on decel, just for the hell of it, whenever basically. But when I junked the emissions crap and threw an ACV plate on, it stoppped. Now I only get the flames on full throttle runs, after I take my foot out of it. It's great when it lights up the dark road behind you.

 

new to me 80 7' pops and small back fires - I am going to get some exhaust work an check all my vacm sys

Ill let you know if this fixes it

 

I have hear these poping and backfiring could be due to bad timing. I have never touched my timing, but im afraid it could be bad, so i picked up my haynes manual and its talking about lights and stuff...isn't there an easy way to set it back to stock?

 

My old RX hadnt started in about 9 years... did the carbon lock trick, started right up. sonce i had a new engine waiting, i decided to give it a rev or 2.


then i floored it.
BANG!!!!!!!!
never started again
i was surprised it even started in the first place

 

When mine sounded like shot gun, I had a hole in the back of my muffler canister.

 

And you guys are digging up a 4 year old thread for what, post count?

 

quit being a troll.

 

Not until you start posting something worth while other than upping your count.

 

lol, i'm trying to get to 1,000!

but to add something useful, my SA does it with the racing beat exaust, just little ones though. Dont' seem to cause any harm.

 

I always look forward to reading your posts, kind of reminds me of House.

 

i bumped it because mine backfires on warm up, when i shift between 1-2 and 2-3... sorry for the bump

 

^ you are forgiven, atleast you know how to use the search button

 

i only heard the "shotgun" backfiring once on my car. never backfired that loud again yet

 

Oh boy, another fan, lol. If I said 1/2 of what I want to somedays, I'd quickly be out the door here.


Bumping old threads is fine, if there is a question involved relating to it. My question is, what happened to your engine after it backfired and wouldn't start again.

 

I feel the same, in fact I find myself editing a lot of my posts because of this.

 

Did my post offend you? are you going to shock an army? steal my oil too?

 

I find most of your posts to be uninformed, uneducated and just plain guessing at things. This is why I've been telling you to post less and read/learn more. Apparently that hasn't soaked in yet.

 

You surely have a quick tongue for a n00b. Talk less and learn more is what Trochoid is trying to get thru your thick skull, and I tend to agree. I would add be a little bit more respectful and thankful to contributing forum members.

Oh, and whatever sassy reply to this post comes to your mind, just spare me.

Kids these days...
