Ok, I have a 89 vert that I am trying to get some good flames out of. Right now 1 out of 10 big pop/booms from the exhaust gives me flames. I have a stock header going to a Racing Beat downpipe replacing the two pre-cats, then to replace the main cat I went to the exhaust shop and had them make a peice of pipe with flanges and fittings as the intermediate pipe, then it goes to the Apex'i N1 duel catback setup. I have the air pump line still going into the exhaust through the custom intermediate pipe. Is the air being pumped into the exhaust hurting my flames or helping? I am still running 89 oct. gas, Should it be higher? Emissions are not a concern. I do plan on getting a RB header in the near future, but what can I do now for bigger natural flames? Any help is appreciated.

run 87 octaine (lower flashpoint)and pull the dashpot of the TB if you havent already done so. i think taking the air pipe off helps a little but not very much in my experience. the 87 realy helps tho i cant even shoot flames on premium.

The dash pot helps control how fast the engine can rev down? correct? will it possibly cause damage or other inconveniences?

andrew lohaus

no. no damage to anyhting. it was another one of thoe lame attempts at "civilizing" the rotary that mazda did with its GT asperations. take it off youle never miss it

I think flames with an NA are so much harder to get. Its usually just a little pop or backfire. Nothing major like on the TIIs. I'd say get some larger injectors and fue pump. Big flames to even match up against a TII.

hard to get on an na? ****, I can shoot them all day long with my sport, can't get them for crap on the TII. I definatly need a timelapse camera!
