Questions about rx7's backfiring
K im still a noob, I talked to a friend about the backfiring and he said its mainly a n/a thing not a tII. I was just wondering if this is true also he said its due to poor tuning.

my 90na shoots 2 foot flames at idle, every 10 seconds or so.. and when i shift in high rpm shoots 2, 3 feet.. ocasionaly.. not often it will pop stupid loud... and shoot anywhere from 4, to 12 feet... its ridiculas.. and you can here the pop over a mile away... ridiculas...
I have RB downpipe, RB pre-silencer and then straight pipe all the way back, no mufflers.

12 feet? i dont believe it unless you have a picture. im sure you blow flames pretty far.
my 87 NA with intake and apexi n1 cat back shot flames after running the engine hard.

ok, my buddy Jestersrain, and mittidrummer on the west forum will voutch for me on this one; We were racing down on the freeway, jestersrain was right off my rear bumper, and mittidrummer was right behind him, when my car poped, the flame went all the way past jestersrain and up to the front of mittidrummer.
Jester said he could feel the heat off of it. and mittie drummer said it was half blue half orange.
I'll try and get some video.. we have video of it popping flames at idle, but none while driving.

I can totally validate for retardedspleen's wicked flame shooting... how many of you have 7s that pop flames at idle? hmmm? I'm waiting? lol... and I'm sure the NO CATS help! heh

I am sad.
My 88 NA never shoots flames. I've had people watch / recorded it on camera / stood behind it and I've never seen it shoot one single flame.
It's def. running rich too. You can smell that clear enough. :-P

I'v got a 90 GTU withstock manifold, 2.5" pre cat tubing, and some OEM look cat back. (It was free from a vert that I stripped at work and it was better than my gutted stock) I was beginning to be sad that I didn't shoot flames until our welder at work told me how he watches me shoot little blue fireballs every time he sees me pull out of our parking lot. I literally jumped up and downwhen I heard that. Now it's time for an ISC header, 2.5 or 3" pre cat tubing, and an Apex'i N1 Dual cat back. I can't wait.
