Okay..... I got rid of the cat's..... 2 1/4 in pipe back to a free flowing muffler..... the cat check valve thing...... I shouldn't have welded it shut right? also, it's a total flamer thrower.... more so then I'd think...... hard core backfiring, I know on reciprication engines, this leads to burnt valves.... how does the rotary hold up...


*preparing for the flame!!!*

 

lol... you wont get flamed from me!!! i love shootin flames!! scares the **** out of the person behind you

 

rotary will hold up fine... it's just from unburnt fuels that are ejected from the motor.

 

I loved that about my rotary. Best way I've ever found to get people to stop riding your ***. Rev, release, rev, fireball...

 

=(
mine is rev, release, rev, smoke screen thick enough to create a thunderstorm.

 

Just make sure the flame is from unburnt fuel and not Detenation

 

It's not hard on the engine to rev it to redline?i have 3" downpipe midpipe and 2.5" catback...I better be spitting flames!

 

As long as you don't hold the engine in redline for extended periods of time your'e cool. once in a while it's actually good for it because it get excess carbon out of your engine. do a search for "definitive reason to redline" and you'll find 1 good post on it.
Peace holmes,

Redlining a rotary-good on the engine, bad on the gas mileage.

This is, of course, assuming the engine and cooling system are in good mechanical working order.

 

u can shoot flames on a non turbo too right?
on my mk2 supra i shoot flames out when i backfire, i think its cause my 3" piping all the way through and its non turbo, what makes rotaries shoot flames?

 

Mine only shoots at high rpm. When my thermosensor was disconnected it actually would breath fire. When it idled flames pulsed out the exhaust. IT was pretty rad but running rich means poor performance.

 

I redline my car 1 time a day to keep carbon from building up. Thanks though, Im going to rev to redline to see if i get any flames

 

ya hoo.... I love my S5.... for an N/A it's perdy schnazzy..... should I get a fuel/air controller to balance out the flamage? that should kicker up a bit right?

 

Well your problem is you're in montana. The lack of civilization is killing your car. Just kidding. IT only sucks moderatly. I stayed in billings for a month and I thought Utah was lame. As far as flamage goes its expected. I had my car tuned properly and the flames turned into a firecracker like flash at 7500rpm. But I'm running straight 2.5" exhaust (straight piped all the way) with a single high flow muffler.

 

Well, billings is in the "I wish I had Mountain Section" I live in the mountains.... and I'm running 2 1/4 in from the manifold back to a high flow, w/ and w/o a siliencer, depending on my mood.... it just sees like it may be out o' tune a little.... but I don't have the tools to properly work on her..... have to start somewhere though..... I'd idealy like to be in the 200-210 hp range..... any other idears?

 

200-210 on stock ports? not going to happen if its n/a... best you can shoot for is really about 170 or so

 

that's a load of bunk!!!..... now I want a turbo!!! OHOOOOOO I GET A TURBO>>> YES!!!!!!!!!!!!!!11
