I took my 3rd gen to a road course last week and a buddy that was following me with a camera showed me that I was throwing flames 8-12 inches from my exhaust at WOT like the Batmobile.

The car was running really hot and it was 89deg late that afternoon.

My mods are listed below and I still have the stock cat.

Am I running way too rich?

 

I think all rx7's run a little rich especially third gen's... mine does the same thing, but I am sure some more people will chime in and tell you a little more about the flames..

 

Flames are cool!! Never heard of anyone shooting them with the stock cats but with high flo have seen it done.

 

I was at the track with Borch and it was like a blow-torch was coming out of his tailpipe. I think he was running very rich, which wasn't a bad thing but it definitely contributed to the flamage and his fuel consumption.

Pretty rad stuff...

 

Dude! thats cool!!!

hehe, any way to guarantee flames?
that would be so frickin awsome to be leaving work,
and shoot some flames at my coworkers on the way out
mwahhahahahah!!

just running rich + really freeflowing exhaust system?

 

Well, I am assuming that the Pettit ECU has the car running rich, but I stil have the stock cat, so the exhaust isn't extremely free flowing.

Unfortunately, I don't want the car running that hot while I am on the track. I guess the next step is the IC to get more air to lean it out a bit?

 

flames are hellacool
