Took the flame arrester out tonight

chance to test yet? I'm assuming this is something you've done before, so whats the end result, she breathes better no?

Should breath way better. . Hoping for better mid and high range with the tune. Should know more after sunday

what exactly does the flame arrester do

Its a emmisions thing really.

The flame arrestor is to prevent backfiring, if enough unburnt fuel is pushed into the exhaust it can cause a backfire with a flame. The flame arrester is there to prevent this.

Now that I took a good look at the pictures... is that on the intake?

Yes its on the manifold

Yeah that's what I thought. I think its more for red tape stuff then anything. It is super restrictive.

Is it running leaner now? I mean that had to of had some effect on the air fuel mix no?

not running lean. The ECU and tuning compensates for the added flow. seems to have better mid rang and top.

ah nice, but yours has obviously been modded. Do you think if you took the flame arrestor out of a stock spark it would affect the mix? Just curious, seems like a simple and free mod and I mean hey if a stocker will also see a better mid-top I'm all game

It would do it to a stock one. . now days the ecu makes the changes it needs.

Nice ill have to yank mine out. My vtech tuner should be showing up today.

I took mine out as well. Good find. I'm all about the cheap/free power mods!

I will keep posting them as I find them.

Hey how would I take the flame arrestor out? Would I need to take the full upper off or simply remove the engine cover?

Yes you would have to remove the full upper, then loosen the clamp on the intake manifold, if your careful you may be able to reuse the clamp but most likely you will need a new one. Just removed it and reclamp and your good.

Will a regular hose/worm gear clamp work, or does it need to be thinner?

Yep, my phone sent this...

size of clamp (or reuse old one) and some "test numbers" on a stocker would be a nice thread! Seat of the pants probably isn't very good..
