How to make exhaust shoot flames??

Danger is my business! :lol: But I don't want to set my bike on fire either.

Here's a toyota cold start injector. i wonder if it would flow enough with only gravity feed and no pump. Anybody know about this? I've never worked with EFI before.

You get one gas nozzle and the electric fuel pump from NOS. Put the nozzle in the pipe about 4" from the end. Put the spark plug almost at the end. Wire it up so when the plug fires, the fuel pump also runs. Nice fire show. That is how the car guys do it.

a buddy of mine used to do this while we were riding...

he would shut off the ignition while rolling with the bike in a tall gear, say 4th or 5th, with the ignition off, and the engine turning over, he then pulled the choke...

the vacuum from the engine turning over pulled LOTS of fuel into the combustion chamber... cams are cranking, fuel goes into exhaust...

next thing he does is turn off the choke, and turns the ignition back on.

ka-BOOOM!!!! 7 or 8 feet of flames out the kerker. if you were too close, he'd singe your eyebrows. the best part was the massive muffled BOOM that it made.

it was quick too, i never could get the combo down pat where i could do it as well as he did.

Gris, I think what happens with those kits is they kill the spark to a cylinder and let the petrol flow on through the exhaust. When you release the button, spark goes back to the cylinder and no more gas in the exhaust. At least that's what I recall from Horsepower TV.

Bingo...My friend has a setup on his 53 pontiac, kill spark a couple plugs, rev it up good, then flip your switch to your plug in the end of the pipe.

How about thick white smoke.....you will need a car windshield washer bottle and some capillary tubing...the basics are fill the washer with mazola oil and inject it into your exhaust through the capillary tubing result massive amounts of white smoke the guy behind you can't see through..if you use canole' oil it will smell like popcorn

so how many psi is the pump we need, and what kind of flow does the nozzle put out? if we want to build a cheap setup with some car parts lying around:whistle:

yup, that's what I want - a cheap homemade rig. I dunno exactly what parts to use though.
