Just curious what setups you guys who shoot flames have. I'm going to assume straight through exhaust, but just wanted to know.

 

Staright pipe from the turbo into an HKS dragger style.

 

Also what pipe diameter.

 

here are the baisics:
full TB mod.
NO CATS WHATSOEVER
fully removed emmsions (helps, but not essential)
the lowest octain you can support (87 for n/a's, how lucky you turbo guys feel when you fill up)
75:1 premix
get her warm, and let em rip!!

the exhaust itself doesnt matter much as long as there are no cats.

 

Smaller pipes should be better for shooting flames (to a point) true duals, no cat, streightthrough mufflers (if any at all) run rich as you can and heat up your pipes as best you can first.

If you really want to go crazy with it, pick up a coil from an old RX-7 and the plugs as well. mount a spark plug in each pipe and plug it into the coil there. When you want flames, rev high and rich, and fire away!

 

RB Turboback, Walbro and Greddy BOV

 

HKS SSQV BOV vented to atmosphere.........2.5" piping(bonez DP)

 

Where does the BOV come into play as far as flame shooting goes?

 

atmospheric BOVs make the car run richer inbetween shifts or when letting off the throttle.

 

if you mount a BOV to the stock piping, you're releasing metered air (cuz it's after the MAF) so when you let off the gas, your mixture goes instantly rich because of all the air escaping... thus.... KABAM!!!

 

I'm guessing u "flamers" don't get good gas mileage.

 

exhaust manifold ONLY!

 

TB mod, no dashpots, no ACV, couple of vac leaks, stock manifold, 2.5" pipe -> 2.5" y -> 2.5" to dual bomz evo mufflers. Works like a charm.

 

Broken tps is all you need to shoot flames.

 

I get about 130 mi to the tank.

 

Retarding the timing also helps.

28mpg on average for me. About 20ish if i sit around shooting flames at everyone I pass

 

17-18 MPG I used to drive and shift at around 4K.......

 

full exhaust + bov = shooting flames

 

Haltech...fuel maps too rich.

Rb header->RB presilencer->2.5" pipe->2.5" magnaflow single straight-through muffler

I had the header+presilencer with the stock catback, and it never had flames with that.

 

Guessing between 25"-30" vacuum?

Mine likes to flame up whenever I really don't want it to...like at night on the highway when I'm not trying to be pulled over...

 

I have an '86 n/a and I'm running really rich on TII injectors, so if i gut the cats on the stock exhaust will it shoot some good flames?

 

86 GXL plus a full RB exhuast and some sideways action laying on the rev limiter. I light up the mountains I'm drifting on

 

'86 Sport, Bonez race pipe, CorkSport catback, TB mod. It blew some nice flames before I gave it a tune-up, but since then (advanced timing back to spec, reset the TPS) it hasn't been so willing to do so. When I get my S-AFR in and tuned, I don't expect to see many at all.

 

Hmm...less oil on the premix...maybe that's why i usually have a puff of smoke at pops instead of a nice blue flame. Maybe i'll use slightly less oil next time.
