i have an 86 n/a with full exhaust and no emissions. My prob is every time i shift or rev it up i get big flame ***** out the exhaust. how do i fix this cus it keeps catching my bumper on fire lol .

 

a friend told me it was runing rich but i dont know how to fix this

 

just need it to stop cus this is the secend bumper i have put on the car.

 

well the problem is:
a) you've got a full exhaust
b) you've got no cats
c) you've got a rotary

to fix the problem, remove one of the above.
or get an AFC and lean it out a little bit (not too much, probably wouldn't help alot anyway and would lead to a blown side seal.)

 

that sucks cus thay are big. i can see them in the rearview mirror lol. it burns the paint

 

stock bumper? why don't you get a tip that extends further past the bumper?

 

thay do like an inch i would juts like it to not do this

 

man, that's the cheapest option IMO, or a longer muffler. bumpers sure aren't cheap.

 

put a metal cat in!! also what kind of exhaust do you have??

 

Umm, make a guard out of aluminum for it? ****, that's funny is all I can say!

 

yea, like asterisk says, you might want to try an aluminum guard like i've seen on some vettes and vipers...else extend the tips way out back

 

+2 on a bumper guard. or drive really slowly and at low rpms which would suck.

 

find out why you are running rich. maybe invest in an safcII to help controle that lil issue. when i had an n/a engine i did this too. same reasons. but i didnt complain. i loved it. i just hated that i could never see the flames

Hey, I'm in Oregon too. I gotta see this ****!

EDIT: we should also take some video and put it on youtube.

 

Make sure the AFM is level if you have an aftermarket intake.

Make sure you have NGK plugs.

Make sure you are running the right fuel pressure (around 43.5 PSI)

Make sure the plug wires are good.

Make sure the injectors arent leaking.

That should be plenty enough to keep the flames down on an NA to keep the bumper from catching fire.

If not, i'm gonna' say get one of those turn pipes and clamp them onto the ends of the tips until you can figure the problem out. Just dont shift or rev the engine near any oil spots, hah.

 

double check you TPS and make shur its set good , it will probly get rid of alot of it

 

where is the tps and got new plugs wires no leaks and it has the stock intake.
where in oregon do you live

 

There's a really good write up on how to adjust it, just search for it.

You should post vids of it too!!

 

Pic of burnt bumper?

 

yes, I too would like to see a flaming bumper!

 

^ +1. Solution : what texfc said or... Rivets + aluminum sheet.

 

Newberg.

 

yes i can get a vid.

 

Have you ever taken a lighter to them at idle?

 

no and a friend just played with tps thay are just the same
